==== 2026-07-11 ====
* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====
* Got PRs merged: [https://github.com/OSGeo/grass/pull/7660 #7660], [https://github.com/OSGeo/grass/pull/7659 #7659],
* Created follow-up PR for sscanf: [https://github.com/OSGeo/grass/pull/7673 #7673]
* Discussed with Stefan Blumentrath:
** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.
* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]
* Video call on FHS
* First review of Fable windows installer in CI on [https://github.com/echoix/grass/pull/664 echoix#664]

==== 2026-07-13 ====
* Reviewed PRs: [https://github.com/OSGeo/grass/pull/7663 #7663], [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass/pull/7337 #7337], [https://github.com/OSGeo/grass/pull/7672 #7672], [https://github.com/OSGeo/grass/pull/7684 #7684], [https://github.com/OSGeo/grass/pull/7687 #7687]
* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]
* Worked on CMake formatting, moving forward the PR a contributor opened for Gersemi, PR [https://github.com/OSGeo/grass/pull/7663 #7663], discussed weird finding with Vashek, lead to issue [https://github.com/OSGeo/grass/issues/7686 #7686]. To be continued the next day.
* Opened PR [https://github.com/OSGeo/grass/pull/7685 #7685] (merged), [https://github.com/OSGeo/grass/pull/7683 #7683] (needs more work/investigation), [https://github.com/OSGeo/grass/pull/7680 #7680] (merged)
* Opened issue to add zizmor to grass-website tools used to check, either local or CI [https://github.com/OSGeo/grass-website/issues/636 grass-website#636]

==== 2026-07-14 ====
* (Early night) Merge PR that updates minimum Python version to 3.11, needed to change the required checks in order to do so. [https://github.com/OSGeo/grass/pull/7684 #7684].
** In the morning, update PRs which were most probably ready, and needed the check passing, like [https://github.com/OSGeo/grass/pull/7329 #7329], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7687 #7687]

* Long review and analysis of [https://github.com/OSGeo/grass-website/pull/646 grass-website#646], coming from a discussion earlier on that using a single workflow to build, but split the deploy part in order to run separately.
* Work on CMake formatting tool: Finally ended up replacing [https://github.com/OSGeo/grass/pull/7663 #7663] with [https://github.com/OSGeo/grass/pull/7696 #7696]. Will close issue [https://github.com/OSGeo/grass/issues/7346 #7346] and [https://github.com/OSGeo/grass/issues/7686 #7686].

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====

* Discussed with Stefan Blumentrath:
** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.
* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]

* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]

** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])

* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.

** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

==== 2026-07-11 ====
* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====

* Created follow-up PR for sscanf: [https://github.com/OSGeo/grass/pull/7673 #7673]
* Discussed with Stefan Blumentrath:
** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.
* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]
* Video call on FHS
* First review of Fable windows installer in CI on [https://github.com/echoix/grass/pull/664 echoix#664]

==== 2026-07-13 ====
* Reviewed PRs: [https://github.com/OSGeo/grass/pull/7663 #7663], [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass/pull/7337 #7337], [https://github.com/OSGeo/grass/pull/7672 #7672], [https://github.com/OSGeo/grass/pull/7684 #7684], [https://github.com/OSGeo/grass/pull/7687 #7687]

* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged

** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])

* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]

** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])

* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]

* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])

** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.
* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]

** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====

* Reviewed PRs: [https://github.com/OSGeo/grass/pull/7663 #7663], [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass/pull/7337 #7337], [https://github.com/OSGeo/grass/pull/7672 #7672], [https://github.com/OSGeo/grass/pull/7684 #7684], [https://github.com/OSGeo/grass/pull/7687 #7687]
* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]
* Worked on CMake formatting, moving forward the PR a contributor opened for Gersemi, PR [https://github.com/OSGeo/grass/pull/7663 #7663], discussed weird finding with Vashek, lead to issue [https://github.com/OSGeo/grass/issues/7686 #7686]. To be continued the next day.
* Opened PR [https://github.com/OSGeo/grass/pull/7685 #7685] (merged), [https://github.com/OSGeo/grass/pull/7683 #7683] (needs more work/investigation), [https://github.com/OSGeo/grass/pull/7680 #7680] (merged)
* Opened issue to add zizmor to grass-website tools used to check, either local or CI [https://github.com/OSGeo/grass-website/issues/636 grass-website#636]

==== 2026-07-14 ====
* (Early night) Merge PR that updates minimum Python version to 3.11, needed to change the required checks in order to do so. [https://github.com/OSGeo/grass/pull/7684 #7684].
** In the morning, update PRs which were most probably ready, and needed the check passing, like [https://github.com/OSGeo/grass/pull/7329 #7329], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7687 #7687]

* Long review and analysis of [https://github.com/OSGeo/grass-website/pull/646 grass-website#646], coming from a discussion earlier on that using a single workflow to build, but split the deploy part in order to run separately.
* Work on CMake formatting tool: Finally ended up replacing [https://github.com/OSGeo/grass/pull/7663 #7663] with [https://github.com/OSGeo/grass/pull/7696 #7696]. Will close issue [https://github.com/OSGeo/grass/issues/7346 #7346] and [https://github.com/OSGeo/grass/issues/7686 #7686].

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])

** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====
* Got PRs merged: [https://github.com/OSGeo/grass/pull/7660 #7660], [https://github.com/OSGeo/grass/pull/7659 #7659],

** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.
* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]

* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])

* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====
* Got PRs merged: [https://github.com/OSGeo/grass/pull/7660 #7660], [https://github.com/OSGeo/grass/pull/7659 #7659],

* Discussed with Stefan Blumentrath:
** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.
* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]
* Video call on FHS
* First review of Fable windows installer in CI on [https://github.com/echoix/grass/pull/664 echoix#664]

==== 2026-07-13 ====
* Reviewed PRs: [https://github.com/OSGeo/grass/pull/7663 #7663], [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass/pull/7337 #7337], [https://github.com/OSGeo/grass/pull/7672 #7672], [https://github.com/OSGeo/grass/pull/7684 #7684], [https://github.com/OSGeo/grass/pull/7687 #7687]
* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

==== 2026-07-11 ====
* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====
* Got PRs merged: [https://github.com/OSGeo/grass/pull/7660 #7660], [https://github.com/OSGeo/grass/pull/7659 #7659],
* Created follow-up PR for sscanf: [https://github.com/OSGeo/grass/pull/7673 #7673]
* Discussed with Stefan Blumentrath:
** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.
* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]
* Video call on FHS
* First review of Fable windows installer in CI on [https://github.com/echoix/grass/pull/664 echoix#664]

==== 2026-07-13 ====
* Reviewed PRs: [https://github.com/OSGeo/grass/pull/7663 #7663], [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass/pull/7337 #7337], [https://github.com/OSGeo/grass/pull/7672 #7672], [https://github.com/OSGeo/grass/pull/7684 #7684], [https://github.com/OSGeo/grass/pull/7687 #7687]
* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]
* Worked on CMake formatting, moving forward the PR a contributor opened for Gersemi, PR [https://github.com/OSGeo/grass/pull/7663 #7663], discussed weird finding with Vashek, lead to issue [https://github.com/OSGeo/grass/issues/7686 #7686]. To be continued the next day.
* Opened PR [https://github.com/OSGeo/grass/pull/7685 #7685] (merged), [https://github.com/OSGeo/grass/pull/7683 #7683] (needs more work/investigation), [https://github.com/OSGeo/grass/pull/7680 #7680] (merged)
* Opened issue to add zizmor to grass-website tools used to check, either local or CI [https://github.com/OSGeo/grass-website/issues/636 grass-website#636]

* Work on CMake formatting tool: Finally ended up replacing [https://github.com/OSGeo/grass/pull/7663 #7663] with [https://github.com/OSGeo/grass/pull/7696 #7696].

GRASS GSoC 2026 Parallelizing r.proj and Raster Processing Modules in GRASS

== Abstract ==
{{cmd|r.proj}} is one of the most commonly used modules in GRASS. It reprojects raster maps between coordinate systems. It has always been single threaded, so on modern multi core hardware most CPU cores sit idle and large reprojections take longer than they need to.

This project parallelizes r.proj and {{cmd|r.param.scale}} using OpenMP, with {{cmd|r.geomorphon}} planned as a third module. The two main obstacles are memory and the PROJ library. A naive parallel version holds the entire input map in RAM, which does not scale to large maps, and PROJ transformation objects cannot be shared between threads. The approach here processes the output map in horizontal bands sized to stay under a user controlled memory cap. For strongly tilted projections where even a single row of output needs more input than the cap allows, each band is further split into smaller column sections until every piece fits. Reading the input and computing the reprojection both run in parallel, with each thread using its own file descriptor and its own PROJ context, while the output is still written in row order so the result is exactly identical to the serial module.

r.param.scale, a terrain analysis module, was parallelized with the same memory bounded idea. Its sequential sliding window was replaced with a two level band and chunk design that honors the memory option. During that work a long standing data race was found in the GRASS math library and fixed. Together these changes give future GRASS contributors a reusable pattern for parallelizing raster modules under a memory constraint.

GRASS Community Meeting San Michele 2026

2026-07-10T15:46:05Z

Neteler: be less mysterious

[[File:Sanmichele.png|frameless|center|1000px|San Michele all'Adige]]

{{toc|right}}

The ''GRASS Community Meeting'' for contributors and developers will be happening from '''July 11 - 19, 2026''' in [https://www.openstreetmap.org/relation/46990#map=12/46.1349/11.1947 San Michele all'Adige, Trentino, Italy].

== Sponsors ==

Sponsors make the event possible. Learn more about [https://grass.osgeo.org/contribute/sponsoring/ Sponsoring].

* [https://www.osgeo.org/ OSGeo]: 2500 USD (see [https://wiki.osgeo.org/w/index.php?title=GRASS_Community_Meeting_2026:_Budget budget]]).

[[File:Osgeo logo.png|none|left|alt=Light and dark green logo of OSGeo saying Your Open Source Compass|Open Source Geospatial Foundation]]

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

== Agenda ==

Agenda is being refined.

=== Saturday, July 11 ===

Day of arrival. Contact organizers (Luca, see FAQ below) if you are interested in individualized program or helping with organization.

Registration is free; participants cover their own travel and lodging (see below), often with employer support — thank you. Ideally we'd reimburse everyone, and every [https://numfocus.org/donate-to-grass donation] or [https://grass.osgeo.org/contribute/sponsoring/ employer sponsorship] of the project helps us get closer.

== Venue ==
The meeting will be hosted at [https://fmach.it/ Fondazione Edmund Mach] (FEM) in San Michele all'Adige, Trentino, Italy — about 15 km north of Trento. FEM is a research and education center with on-site facilities that allow participants to work, sleep, and eat in the same location.

[https://maps.app.goo.gl/5YEuEts6qXvky7HD9 Map]

=== Getting there ===

San Michele all'Adige is reachable by train on the Trento–Bolzano line (Trento or Mezzocorona station), with frequent connections from Trento (~15 minutes) and Verona (~1 hour). The nearest airports are Verona (VRN), Venice Marco Polo (VCE) and Treviso (TSF), Milan Bergamo (BGY), Malpensa (MXP), and Linate (LIN), Bologna (BLQ), and Innsbruck (INN) in Austria. Trento is also the host city of FOSS4G Italy 2026 (July 9–11), making it convenient to combine both events.

From Trento main train station you need to move to Ferrovia Trento-Malè (FTM) train station (few minutes by walk, https://www.openstreetmap.org/#map=17/46.072739/11.120814) and there take a train to Grumo/San Michele all'Adige. Train timetable is [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20ANDATA.pdf here], the opposite way is [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20RITORNO.pdf this one]

Another possibility is to arrive with the main train (Ferrovie dello Stato) in Mezzocorona and here you can walk to San Michele (around 20 minutes by walk) or take the small train Trento-Malè from Mezzocorona Ferrovia station (in front of main train station https://www.openstreetmap.org/#map=18/46.206633/11.128024) and stop in Grumo/San Michele (you need to look for the [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20RITORNO.pdf way back schedule])

== Accommodation and Costs ==

''Registration is free''. However, participants should plan for the following costs:

* Travel
* Lodging

Participants can stay on-site at the FEM convitto (dormitory), keeping the community together for the full duration of the meeting:

* €35 per person per night
* Double and triple rooms (triples include a small kitchen)
* A mandatory on-site supervisor is required at €200 per night (flat fee, shared across the group)
* Family members are welcome to stay in the dormitory as well
* [https://cif.fmach.it/content/download/2701/78358/file/brochure_convitto.pdf Brochure]
* For '''lodging booking''' options: see [https://grasscommunitymeeting2026.eventbrite.it/ Eventbrite]

For anyone preferring alternative lodging, hotels and B&Bs are available in San Michele and nearby Trento.

Lunches on weekdays can be taken at the FEM canteen (mensa), located on the same campus. Details and pricing are being finalized.

== Individual Preparation ==

* Bring your own computer
* Bring {{wikipedia|AC power plugs and sockets|power adapter}} if needed (Italy: 230V, 50Hz, {{wikipedia|Europlug|Type C}}, {{wikipedia|Schuko|Type F}}, and {{wikipedia|AC power plugs and sockets: L|Type L}} sockets are common)
* Install git and the compiler tools, and come with a working GRASS development environment if possible. See [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md here] for details.

== FAQ ==

* ''Is this a conference?''
** Talks or presentations may be included, but the purpose is to work together on the project. Among conference formats, the closest comparison would be a participatory workshop.
* ''Is this a hackathon?''
** While there is plenty of intensive coding, the meeting is not competitive. We meet to collaborate.
* ''Is the GRASS Community Meeting for developers only?''
** No, the meeting is open to all users, supporters, contributors, power users, and developers ''who want to make a meaningful contribution to the project''.
* ''What skills do I need?''
** Coding skills are not required. Contributions to documentation, tutorials, translations, website, and testing are all valuable. Practical help during the meeting, such as coordinating meals, photography, or reporting, is a real contribution too.
* ''Can I attend remotely?''
** The meeting is in-person, but everyone is welcome to use the same week for focused work on the project from wherever they are.
* ''What language is used during the meeting?''
** English is the working language, but you may hear several other languages spoken at the event.
* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''Where can I get help and more information about the community meeting?''
** Contact local organizer [[User:Lucadelu|Luca Delucchi]] (<tt><lucadeluge at gmail com></tt>) or [[User:wenzeslaus|Vaclav Petras]] (<tt><wenzeslaus at gmail com></tt>) for budget questions.
* ''What if I can't spend time on this?''
** Can you spend money instead? [https://numfocus.org/donate-to-grass Donate to GRASS through NumFOCUS] to help keep the project going.

We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

Registration is free; participants cover their own travel and lodging (see below), often with employer support — thank you. Ideally we'd reimburse everyone, and every [https://numfocus.org/donate-to-grass donation] or [https://grass.osgeo.org/contribute/sponsoring/ employer sponsorship] of the project helps us get closer.

== Venue ==
The meeting will be hosted at [https://fmach.it/ Fondazione Edmund Mach] (FEM) in San Michele all'Adige, Trentino, Italy — about 15 km north of Trento. FEM is a research and education center with on-site facilities that allow participants to work, sleep, and eat in the same location.

[https://maps.app.goo.gl/5YEuEts6qXvky7HD9 Map]

=== Getting there ===

San Michele all'Adige is reachable by train on the Trento–Bolzano line (Trento or Mezzocorona station), with frequent connections from Trento (~15 minutes) and Verona (~1 hour). The nearest airports are Verona (VRN), Venice Marco Polo (VCE) and Treviso (TSF), Milan Bergamo (BGY), Malpensa (MXP), and Linate (LIN), Bologna (BLQ), and Innsbruck (INN) in Austria. Trento is also the host city of FOSS4G Italy 2026 (July 9–11), making it convenient to combine both events.

From Trento main train station you need to move to Ferrovia Trento-Malè (FTM) train station (few minutes by walk, https://www.openstreetmap.org/#map=17/46.072739/11.120814) and there take a train to Grumo/San Michele all'Adige. Train timetable is [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20ANDATA.pdf here], the opposite way is [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20RITORNO.pdf this one]

Another possibility is to arrive with the main train (Ferrovie dello Stato) in Mezzocorona and here you can walk to San Michele (around 20 minutes by walk) or take the small train Trento-Malè from Mezzocorona Ferrovia station (in front of main train station https://www.openstreetmap.org/#map=18/46.206633/11.128024) and stop in Grumo/San Michele (you need to look for the [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20RITORNO.pdf way back schedule])

== Accommodation and Costs ==

''Registration is free''. However, participants should plan for the following costs:

* Travel
* Lodging

Participants can stay on-site at the FEM convitto (dormitory), keeping the community together for the full duration of the meeting:

* €35 per person per night
* Double and triple rooms (triples include a small kitchen)
* A mandatory on-site supervisor is required at €200 per night (flat fee, shared across the group)
* Family members are welcome to stay in the dormitory as well
* [https://cif.fmach.it/content/download/2701/78358/file/brochure_convitto.pdf Brochure]
* For '''lodging booking''' options: see [https://grasscommunitymeeting2026.eventbrite.it/ Eventbrite]

For anyone preferring alternative lodging, hotels and B&Bs are available in San Michele and nearby Trento.

Lunches on weekdays can be taken at the FEM canteen (mensa), located on the same campus. Details and pricing are being finalized.

== Individual Preparation ==

* Bring your own computer
* Bring {{wikipedia|AC power plugs and sockets|power adapter}} if needed (Italy: 230V, 50Hz, {{wikipedia|Europlug|Type C}}, {{wikipedia|Schuko|Type F}}, and {{wikipedia|AC power plugs and sockets: L|Type L}} sockets are common)
* Install git and the compiler tools, and come with a working GRASS development environment if possible. See [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md here] for details.

== FAQ ==

* ''Is this a conference?''
** Talks or presentations may be included, but the purpose is to work together on the project. Among conference formats, the closest comparison would be a participatory workshop.
* ''Is this a hackathon?''
** While there is plenty of intensive coding, the meeting is not competitive. We meet to collaborate.
* ''Is the GRASS Community Meeting for developers only?''
** No, the meeting is open to all users, supporters, contributors, power users, and developers ''who want to make a meaningful contribution to the project''.
* ''What skills do I need?''
** Coding skills are not required. Contributions to documentation, tutorials, translations, website, and testing are all valuable. Practical help during the meeting, such as coordinating meals, photography, or reporting, is a real contribution too.
* ''Can I attend remotely?''
** The meeting is in-person, but everyone is welcome to use the same week for focused work on the project from wherever they are.
* ''What language is used during the meeting?''
** English is the working language, but you may hear several other languages spoken at the event.
* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''Where can I get help and more information about the community meeting?''
** Contact local organizer [[User:Lucadelu|Luca Delucchi]] (<tt><lucadeluge at gmail com></tt>) or [[User:wenzeslaus|Vaclav Petras]] (<tt><wenzeslaus at gmail com></tt>) for budget questions.
* ''What if I can't spend time on this?''
** Can you spend money instead? [https://numfocus.org/donate-to-grass Donate to GRASS through NumFOCUS] to help keep the project going.

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways.

The meeting will be hosted at [https://fmach.it/ Fondazione Edmund Mach] (FEM) in San Michele all'Adige, Trentino, Italy — about 15 km north of Trento. FEM is a research and education center with on-site facilities that allow participants to work, sleep, and eat in the same location.

[https://maps.app.goo.gl/5YEuEts6qXvky7HD9 Map]

=== Getting there ===

San Michele all'Adige is reachable by train on the Trento–Bolzano line (Trento or Mezzocorona station), with frequent connections from Trento (~15 minutes) and Verona (~1 hour). The nearest airports are Verona (VRN), Venice Marco Polo (VCE) and Treviso (TSF), Milan Bergamo (BGY), Malpensa (MXP), and Linate (LIN), Bologna (BLQ), and Innsbruck (INN) in Austria. Trento is also the host city of FOSS4G Italy 2026 (July 9–11), making it convenient to combine both events.

From Trento main train station you need to move to Ferrovia Trento-Malè (FTM) train station (few minutes by walk, https://www.openstreetmap.org/#map=17/46.072739/11.120814) and there take a train to Grumo/San Michele all'Adige. Train timetable is [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20ANDATA.pdf here], the opposite way is [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20RITORNO.pdf this one]

Another possibility is to arrive with the main train (Ferrovie dello Stato) in Mezzocorona and here you can walk to San Michele (around 20 minutes by walk) or take the small train Trento-Malè from Mezzocorona Ferrovia station (in front of main train station https://www.openstreetmap.org/#map=18/46.206633/11.128024) and stop in Grumo/San Michele (you need to look for the [https://www.trentinotrasporti.it/images/allegati/ferrovia/ftm/FTM%20est2026%20-%20RITORNO.pdf way back schedule])

== Accommodation and Costs ==

''Registration is free''. However, participants should plan for the following costs:

* Travel
* Lodging

Participants can stay on-site at the FEM convitto (dormitory), keeping the community together for the full duration of the meeting:

* €35 per person per night
* Double and triple rooms (triples include a small kitchen)
* A mandatory on-site supervisor is required at €200 per night (flat fee, shared across the group)
* Family members are welcome to stay in the dormitory as well
* [https://cif.fmach.it/content/download/2701/78358/file/brochure_convitto.pdf Brochure]
* For '''lodging booking''' options: see [https://grasscommunitymeeting2026.eventbrite.it/ Eventbrite]

For anyone preferring alternative lodging, hotels and B&Bs are available in San Michele and nearby Trento.

Lunches on weekdays can be taken at the FEM canteen (mensa), located on the same campus. Details and pricing are being finalized.

== Individual Preparation ==

* Bring your own computer
* Bring {{wikipedia|AC power plugs and sockets|power adapter}} if needed (Italy: 230V, 50Hz, {{wikipedia|Europlug|Type C}}, {{wikipedia|Schuko|Type F}}, and {{wikipedia|AC power plugs and sockets: L|Type L}} sockets are common)
* Install git and the compiler tools, and come with a working GRASS development environment if possible. See [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md here] for details.

== FAQ ==

* ''Is this a conference?''
** Talks or presentations may be included, but the purpose is to work together on the project. Among conference formats, the closest comparison would be a participatory workshop.
* ''Is this a hackathon?''
** While there is plenty of intensive coding, the meeting is not competitive. We meet to collaborate.
* ''Is the GRASS Community Meeting for developers only?''
** No, the meeting is open to all users, supporters, contributors, power users, and developers ''who want to make a meaningful contribution to the project''.
* ''What skills do I need?''
** Coding skills are not required. Contributions to documentation, tutorials, translations, website, and testing are all valuable. Practical help during the meeting, such as coordinating meals, photography, or reporting, is a real contribution too.
* ''Can I attend remotely?''
** The meeting is in-person, but everyone is welcome to use the same week for focused work on the project from wherever they are.
* ''What language is used during the meeting?''
** English is the working language, but you may hear several other languages spoken at the event.
* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''Where can I get help and more information about the community meeting?''
** Contact local organizer [[User:Lucadelu|Luca Delucchi]] (<tt><lucadeluge at gmail com></tt>) or [[User:wenzeslaus|Vaclav Petras]] (<tt><wenzeslaus at gmail com></tt>) for budget questions.
* ''What if I can't spend time on this?''
** Can you spend money instead? [https://numfocus.org/donate-to-grass Donate to GRASS through NumFOCUS] to help keep the project going.

Neteler: /* GitHub issues (2020 - present time) */ + Migrating GRASS code repository from SVN to git

== Introduction ==

=== GitHub issues (2020 - present time) ===

Jan 23, 2020, we switched from trac to GitHub also for the bug tracking (now called "issues").

:'''https://github.com/OSGeo/grass/issues'''

See
* announcement: https://grass.osgeo.org/news/2020_01_23_grass_gis_issues_now_on_github/
* notes: https://neteler.org/blog/remarks-on-svn-trac-to-github-migration/
* Migrating GRASS code repository from SVN to git: https://trac.osgeo.org/grass/wiki/GitMigration

=== trac (2007 - 2020) ===

Since 9 Dec 2007 we use '''Trac'''. [http://trac.edgewall.org Trac] is an open source, web-based project management and bug-tracking tool, inspired by CVSTrac. It is developed and maintained by Edgewall Software.

:'''http://trac.osgeo.org/grass'''

Historical note: The GForge and RT can be used to examine the previously resolved issues, and those that were still in progress as the new system was released. It would be good to move all the tickets from the former trackers to the new one, but nodody has volunteered yet. If you are the one, please contact the admin to arrange it.

=== GForge (2007 - 2008) ===

Used: Jan 2007 - Dec 2008

The former tracker was [http://gforge.org GForge] (a feature-rich system for collaborating on a software project). Under the [http://wald.intevation.org/ GForge setup by Intevation company], there is a [http://wald.intevation.org/tracker/?group_id=21 set of trackers for the GRASS project].

==== Participate ====

The trackers are available for public view, but in order to be able to post (including creating a new report), and to use all the features of the trackers, you need to [http://wald.intevation.org/account/register.php setup an account at GForge] and [http://wald.intevation.org/project/request.php?group_id=21 join the GRASS project at GForge].

==== GForge: How it works ====

''(note: historic section)''

All trackers' new submissions are automatically forwarded to the [http://grass.itc.it/community/support.php#devellists GRASS development mailing list]. The followup traffic is stored in the tracker, and forwarded only to parties discussing the ticket. However, any project member can "monitor" a ticket, or a whole tracker, in order to receive all the related traffic (see [http://gforge.org/docman/index.php?group_id=1&selected_doc_group_id=5&language_id=1 GForge manuals]).

:[[User:Landa|Martin Landa]]

There are 3 project member roles: ''admin'', ''developer'' and ''user''.

; ''admin'': Manages requests to join the project and maintains the GRASS project's setup at GForge.

; ''developer'': Can do most of the things that admin can. Only that he doesn't have his duties and he can't remove the whole GRASS project. But he still can add/modify/delete trackers as well as delete tickets for good. It was neccessary to provide that much power to ''developers'' so that they could move tickets between the trackers. ''Developers'' - please use your power wisely and let the admin know before doing something more intrusive you are not sure about :).

; ''user'': Can open new tickets in the trackers, reply to other tickets and ''monitor'', participate in surveys (''admin'' and ''developer'' can too, of course).

===== Buggy GForge bugtracker? =====

When you spot something wrong or a possible enhacement in the setup of GRASS trackers at GForge, please drop admin a line. If it's a bug or a missing feature in the GForge software itself, please report it to [http://wald.intevation.org/projects/siteadmin wald.intevation.org GForge site maintainers], preferably using [http://wald.intevation.org/tracker/?atid=162&group_id=1&func=browse their bugtracker]. If unsure whether the issue is in the GRASS trackers setup, or in the GForge itself, contact admin first, or ask on [http://grass.itc.it/devel/index.php#list GRASS dev ML].

Current top issues with GForge from the point of view of GRASS team, which hamper info flow and productivity:

* [http://wald.intevation.org/tracker/index.php?func=detail&aid=300&group_id=1&atid=162 can't CC an email from GForge]
* <strike>[http://wald.intevation.org/tracker/index.php?func=detail&aid=360&group_id=1&atid=162 whole discussion included in the email notification = noise]</strike> ''fixed by Sascha Wilde on 18.07.2007''

===== GForge: beyond the trackers =====

GForge provides many functionalities. Currently we use only the trackers, as all the other functionalities are implemented in the current GRASS infrastructure (besides surveys; maybe there will be some use for them - let's keep them in mind :) ). However, it is worth rembering that GForge can provide things like discussion forums, mailing lists, ftp space, SVN server and some more.

''NOTE, 2007.04.07: according to [http://www.nabble.com/d.menu%2C-d.ask-tf3385241.html#a9832649 discussion on GRASS dev ML], [[SVN hosting|migration to SVN]] is planned soon.''

=== Request Tracker RT (2000 - 2006) ===

Used: Dec 2000 - Dec 2006

There is also the even older [https://web.archive.org/web/20070630161517/http://intevation.de/rt/webrt?q_status=open&q_queue=grass GRASS Request Tracker] - RT.

=== Bug tracking in early days (1982 - 1999) ===

The entire bug tracking was done manually, through emails (with focus on the mailing lists).

GRASS Community Meeting San Michele 2026

2026-06-19T13:46:05Z

Neteler: For lodging booking options: see https://grasscommunitymeeting2026.eventbrite.it/

[[File:Sanmichele.png|frameless|center|1000px|San Michele all'Adige]]

{{toc|right}}

The ''GRASS Community Meeting'' for contributors and developers will be happening from '''July 11 - 19, 2026''' in [https://www.openstreetmap.org/relation/46990#map=12/46.1349/11.1947 San Michele all'Adige, Trentino, Italy].

== Sponsors ==

Sponsors make the event possible. Learn more about [https://grass.osgeo.org/contribute/sponsoring/ Sponsoring].

* [https://www.osgeo.org/ OSGeo]: 2500 USD (see [https://wiki.osgeo.org/w/index.php?title=GRASS_Community_Meeting_2026:_Budget budget]]).

[[File:Osgeo logo.png|none|left|alt=Light and dark green logo of OSGeo saying Your Open Source Compass|Open Source Geospatial Foundation]]

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

== Agenda ==

Agenda is being refined.

=== Saturday, July 11 ===

Day of arrival. Contact organizers if you are interested in individualized program or helping with organization.

Registration is free; participants cover their own travel and lodging (see below), often with employer support — thank you. Ideally we'd reimburse everyone, and every [https://numfocus.org/donate-to-grass donation] or [https://grass.osgeo.org/contribute/sponsoring/ employer sponsorship] of the project helps us get closer.

== Venue ==
The meeting will be hosted at [https://fmach.it/ Fondazione Edmund Mach] (FEM) in San Michele all'Adige, Trentino, Italy — about 15 km north of Trento. FEM is a research and education center with on-site facilities that allow participants to work, sleep, and eat in the same location.

[https://maps.app.goo.gl/5YEuEts6qXvky7HD9 Map]

=== Getting there ===

San Michele all'Adige is reachable by train on the Trento–Bolzano line (San Michele all'Adige–Mezzocorona station), with frequent connections from Trento (~15 minutes) and Verona (~1 hour). The nearest airports are Verona (VRN), Venice Marco Polo (VCE) and Treviso (TSF), Milan Bergamo (BGY), Malpensa (MXP), and Linate (LIN), Bologna (BLQ), and Innsbruck (INN) in Austria. Trento is also the host city of FOSS4G Italy 2026 (July 9–11), making it convenient to combine both events.

== Accommodation and Costs ==

''Registration is free''. However, participants should plan for the following costs:

* Travel
* Lodging

Participants can stay on-site at the FEM convitto (dormitory), keeping the community together for the full duration of the meeting:

* €35 per person per night
* Double and triple rooms (triples include a small kitchen)
* A mandatory on-site supervisor is required at €200 per night (flat fee, shared across the group)
* Family members are welcome to stay in the dormitory as well
* [https://cif.fmach.it/content/download/2701/78358/file/brochure_convitto.pdf Brochure]
* For '''lodging booking''' options: see [https://grasscommunitymeeting2026.eventbrite.it/ Eventbrite]

For anyone preferring alternative lodging, hotels and B&Bs are available in San Michele and nearby Trento.

Lunches on weekdays can be taken at the FEM canteen (mensa), located on the same campus. Details and pricing are being finalized.

== Individual Preparation ==

* Bring your own computer
* Bring {{wikipedia|AC power plugs and sockets|power adapter}} if needed (Italy: 230V, 50Hz, {{wikipedia|Europlug|Type C}}, {{wikipedia|Schuko|Type F}}, and {{wikipedia|AC power plugs and sockets: L|Type L}} sockets are common)
* Install git and the compiler tools, and come with a working GRASS development environment if possible. See [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md here] for details.

== FAQ ==

* ''Is this a conference?''
** Talks or presentations may be included, but the purpose is to work together on the project. Among conference formats, the closest comparison would be a participatory workshop.
* ''Is this a hackathon?''
** While there is plenty of intensive coding, the meeting is not competitive. We meet to collaborate.
* ''Is the GRASS Community Meeting for developers only?''
** No, the meeting is open to all users, supporters, contributors, power users, and developers ''who want to make a meaningful contribution to the project''.
* ''What skills do I need?''
** Coding skills are not required. Contributions to documentation, tutorials, translations, website, and testing are all valuable. Practical help during the meeting, such as coordinating meals, photography, or reporting, is a real contribution too.
* ''Can I attend remotely?''
** The meeting is in-person, but everyone is welcome to use the same week for focused work on the project from wherever they are.
* ''What language is used during the meeting?''
** English is the working language, but you may hear several other languages spoken at the event.
* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''Where can I get help and more information about the community meeting?''
** Contact local organizer [[User:Lucadelu|Luca Delucchi]] (<tt><lucadeluge at gmail com></tt>) or [[User:wenzeslaus|Vaclav Petras]] (<tt><wenzeslaus at gmail com></tt>) for budget questions.
* ''What if I can't spend time on this?''
** Can you spend money instead? [https://numfocus.org/donate-to-grass Donate to GRASS through NumFOCUS] to help keep the project going.

GRASS Community Meeting San Michele 2026

2026-06-08T14:53:54Z

Neteler: update arrival + activities (Markus)

[[File:Sanmichele.png|frameless|center|1000px|San Michele all'Adige]]

{{toc|right}}

The ''GRASS Community Meeting'' for contributors and developers will be happening from '''July 11 - 19, 2026''' in [https://www.openstreetmap.org/relation/46990#map=12/46.1349/11.1947 San Michele all'Adige, Trentino, Italy].

== Sponsors ==

Sponsors make the event possible. Learn more about [https://grass.osgeo.org/contribute/sponsoring/ Sponsoring].

* [https://www.osgeo.org/ OSGeo]: 2500 USD (see [https://wiki.osgeo.org/w/index.php?title=GRASS_Community_Meeting_2026:_Budget budget]]).

[[File:Osgeo logo.png|none|left|alt=Light and dark green logo of OSGeo saying Your Open Source Compass|Open Source Geospatial Foundation]]

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

== Agenda ==

Agenda is being refined.

=== Saturday, July 11 ===

Day of arrival. Contact organizers if you are interested in individualized program or helping with organization.

=== Sunday, July 12 ===

The ''GRASS Community Meeting'' for contributors and developers will be happening from '''July 11 to June 19, 2026''' in [https://www.openstreetmap.org/relation/46990#map=12/46.1349/11.1947 San Michele all'Adige, Trentino, Italy].

[[File:Osgeo logo.png|none|left|alt=Light and dark green logo of OSGeo saying Your Open Source Compass|Open Source Geospatial Foundation]]

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

== Venue ==
The meeting will be hosted at [https://fmach.it/ Fondazione Edmund Mach] (FEM) in San Michele all'Adige, Trentino, Italy — about 15 km north of Trento. FEM is a research and education center with on-site facilities that allow participants to work, sleep, and eat in the same location.

[https://maps.app.goo.gl/5YEuEts6qXvky7HD9 Map]

=== Getting there ===

San Michele all'Adige is reachable by train on the Trento–Bolzano line (San Michele all'Adige–Mezzocorona station), with frequent connections from Trento (~15 minutes) and Verona (~1 hour). The nearest airports are Verona (VRN), Venice Marco Polo (VCE) and Treviso (TSF), Milan Bergamo (BGY), Malpensa (MXP), and Linate (LIN), Bologna (BLQ), and Innsbruck (INN) in Austria. Trento is also the host city of FOSS4G Italy 2026 (July 9–11), making it convenient to combine both events.

== Accommodation and Costs ==

''Participation is free of charge''. However, participants should plan for the following costs:

* Travel
* Lodging

Participants can stay on-site at the FEM convitto (dormitory), keeping the community together for the full duration of the meeting:

* €35 per person per night
* Double and triple rooms (triples include a small kitchen)
* A mandatory on-site supervisor is required at €200 per night (flat fee, shared across the group)
* Family members are welcome to stay in the dormitory as well
* [https://cif.fmach.it/content/download/2701/78358/file/brochure_convitto.pdf Brochure]

For anyone preferring alternative lodging, hotels and B&Bs are available in San Michele and nearby Trento.

Lunches on weekdays can be taken at the FEM canteen (mensa), located on the same campus. Details and pricing are being finalized.

== Individual Preparation ==

* Bring your own computer
* Bring {{wikipedia|AC power plugs and sockets|power adapter}} if needed (Italy: 230V, 50Hz, {{wikipedia|Europlug|Type C}}, {{wikipedia|Schuko|Type F}}, and {{wikipedia|AC power plugs and sockets: L|Type L}} sockets are common)
* Install git and the compiler tools, and come with a working GRASS development environment if possible. See [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md here] for details.

== FAQ ==

* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''Is the GRASS Community Meeting for developers only?''
** No, the meeting is open to all users, supporters, contributors, power users and developers ''who want to make a meaningful contribution to the project''.
* ''Where can I get help and more information about the community meeting?''
** Contact local organizer [[User:Lucadelu|Luca Delucchi]] (<tt><lucadeluge at gmail com></tt>) or [[User:wenzeslaus|Vaclav Petras]] (<tt><wenzeslaus at gmail com></tt>) for budget questions.

Compile and Install

2026-04-02T12:21:04Z

Neteler: +python3-pip; fix libfftw3

'''Disclaimer''': This page explains how to turn the GRASS source code into an installable binary package ("compilation") for different operating systems. If you just want to get ready-to-use binaries, go [https://grass.osgeo.org/download/ here], otherwise read on...

== How to do compilation and installation of GRASS? ==

Here we explain the procedure to compile GRASS from GitHub, but it also applies to official GRASS 8 releases.

''For installation of precompiled binary packages, see the main [[Installation Guide]].''

For detailed information on compilation, please see the [https://github.com/OSGeo/grass/blob/main/INSTALL.md INSTALL] file in the source code.

=== Prerequisites ===

==== Extra libraries ====
GRASS needs at least two extra libraries: PROJ and GDAL/OGR. It is recommended to download them as ready-to-use packages for your software platform (Linux distribution, Windows, Mac...).

Other libraries needed to run GRASS are listed on the [https://github.com/OSGeo/grass/blob/main/REQUIREMENTS.md requirements page].

To compile, you will also need the respective "-devel" packages; see below for details.

==== Download GRASS source code ====

First, [https://grass.osgeo.org/download/ download the GRASS source code].

=== Generic Compilation and installation procedure ===

* It is wise that compilation processes are carried out as a normal user: If you want to get the source code in a place where you do not have write permissions (e.g. in /usr/local/src/) just follow this:
cd /usr/local/src/
su -c 'mkdir grass8'
su -c 'chown yourlogin:yourgroup grass8'

Otherwise if you have permissions just continue as a normal user:
mkdir $HOME/src
cd $HOME/src/
git clone https://github.com/OSGeo/grass.git grass_main

* run configure with parameters to adapt the compile process to your own system. To see what options can be passed to it, run:
./configure --help | less


It may (!) look like this:

./configure \
--with-cxx \
--with-sqlite \
--with-python \
--with-geos \
--with-gdal=/usr/bin/gdal-config \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype \
--with-freetype-includes=/usr/include/freetype2 \
--with-proj --with-proj-share=/usr/share/proj

You may have to explicitly state the path for certain packages (i.e., gdal). The Unix 'locate' command will come in handy for finding the path of the package you need (you may have to run locate as root ex: sudo locate gdal-config).

Please note that the paths mentioned may widely vary due to the distribution used.
See [[Compile_and_Install#Platform_Specific_Notes|Platform Specific Notes]] below.

Depending on your needs it may be a good idea to include debugging hooks.
: See [[GRASS_Debugging#Compile_Time_Setup]].
CFLAGS="-ggdb -Wall -Werror-implicit-function-declaration" ./configure ...

At the end of configuration process you should get report not much different from this:

GRASS is now configured for: x86_64-pc-linux-gnu

Source directory: /home/user/software/grass_main
Build directory: /home/user/software/grass_main
Installation directory: ${prefix}/grass84

[...]

* Let's compile it (takes a little while...)!
make -j2
* At the end, you should get report not much different from this:
----------------------------------------------------------------------
Following modules are missing the 'description.html' file in src code:

GRASS compilation log
-------------------------
Started compilation: Mon 19 Aug 2024 10:47:57 PM CEST
--
Errors in:
No errors detected.
--
Finished compilation: Mon 19 Aug 2024 10:55:12 PM CEST
(In case of errors please change into the directory with error and run 'make')

* If there is any error, change directory to directory with error and run "make" again. Report occurring bug to GRASS mailing list
* Once the installation process is finished, you're ready to install GRASS system wide.
su -c 'make install'
* enjoy GRASS:
grass

=== What else? ===

If you want to use [https://www.qgis.org QGIS], then also compile the GRASS-GDAL/OGR plugin. This is also useful to access your GRASS-data
from other application using GDAL/OGR like [[R_statistics/ R]].
* [[Compile and install GRASS and QGIS with GDAL/OGR Plugin]] (enables QGIS to read GRASS data directly)

=== Compile and install GDAL-GRASS plugin ===

* See [[Compile and install GDAL-GRASS plugin]]

=== Platform Specific Notes ===

==== Linux ====

Linux comes in various flavours, i.e. distributions.

===== Distribution related packaging =====

</source>

===== Archlinux =====
You can install GRASS for Archlinux distribution based like Archlinux, Manjaro, EndeavourOS ...

* <big>'''Easiest method : use a prebuilt package using arch4edu repository'''</big>
''"Arch4edu is a community repository for Arch Linux and Arch Linux ARM that strives to provide the latest versions of most software used by college students."''

1. Add Arch4edu repository. Follow instructions from official documentation:

https://github.com/arch4edu/arch4edu/wiki/Add-arch4edu-to-your-Archlinux

2. Refresh packages list with

pacman -Syyu

3. Install GRASS package

pacman -S grass

* <big>'''Advanced method : use AUR (Arch User Repository) package'''</big>
Up-to-date links to Archlinux GRASS PKGBUILDs are on Arch User Repository.
PKGBUILD downloads and builds automatically sources from https://grass.osgeo.org/download/software/linux/.

You can use an AUR helper like ''pamac'', ''yay'', among others ... More info through this link https://wiki.archlinux.org/title/AUR_helpers

Exemple with ''yay'':
yay -S grass

* <big>'''Expert method : compile from source code'''</big>
If you want to compile it yourself, you could follow steps below :

''(As an alternative it is recommended to download PKGBUILD from AUR and then customize to your needs)''

Install dependencies :
pacman -S bzip2 cairo fftw fontconfig freetype2 gcc-libs gdal geos glibc glu libpng libtiff libx11 libgl netcdf pdal proj python-gdal python-numpy python-pillow python-wxpython readline zlib zstd

Download and extract sources : https://grass.osgeo.org/download/software/sources/

We can now start building GRASS

export PATH=~/usr/bin:$PATH && \
./configure \
--with-freetype-includes=/usr/include/freetype2 \
--with-wxwidgets \
--with-readline \
--with-pthread \
--with-netcdf \
--with-nls \
--with-geos \
--with-postgres \
--with-pdal=/usr/include/pdal \
--with-bzlib \
--with-zstd

Now let's compile and install it

make
make install

It's done, you can enjoy GRASS in Arch, just type "grass" in the terminal to launch it or look for grass in your menu.

===== Generic procedure for Debian-based distributions (Ubuntu, ...) =====

WORK IN PROGRESS

1. Install official GRASS package

sudo apt install grass grass-dev

2. Enable source code download

# do backup first
sudo cp /etc/apt/sources.list /etc/apt/sources.list.orig
sudo sed -i '/^#\sdeb-src /s/^# *//' /etc/apt/sources.list

3. Install GRASS dependencies

sudo apt build-dep grass

4. Download GRASS source code

git clone https://github.com/osgeo/grass

5. Compile GRASS from source code

cd grass

Configure:

grass --config build | sh

Optionally install missing dependencies (can happen when official GRASS package is not compatible with GRASS main), eg.

sudo apt install libzstd-dev

Compile:

make -j2

===== Ubuntu =====

There is a dedicated page on how to [[Compile_and_Install_Ubuntu | Compile the GRASS source code & install it in Ubuntu]].

===== Linux Mint =====

The [[Compile_and_Install_Ubuntu | detailed compilation guide for Ubuntu]] may just work. However, here is a short guide for Mint:

<source lang="bash">
# Linux Mint 21+

# be sure to have an updated system
sudo apt-get update && sudo apt-get upgrade -y

# installation of required libraries and compile tools
# recommended to give Python3 precedence over Python2 (which is end-of-life since 2024)
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1

# install compiler tools and further dependencies (tested with Linux Mint 21)
# this is a single command, please copy-paste it entirely into the terminal:
sudo apt-get install \

</source>

Next steps:
* create a subdirectory in your HOME tree for storing the GRASS source code (and later compilation)
* get source code, one of the two options:
** a) download [https://grass.osgeo.org/grass-stable/source/snapshot/ GRASS source code weekly snapshot] (e.g. take the "8.x.git snapshot"), or
*** unpack source code
** b) current source code from GitHub:
*** <code>git clone https://github.com/OSGeo/grass.git</code>
* change into the source code directory

<source lang="bash">
# in the source code directory, "configure" the source code to prepare for compilation:

===== Enterprise Linux =====

Enterprise Linux (EL) and derivatives (that is, Red Hat Enterprise Linux, CentOS and Scientific Linux) is a popular and robust platform for servers and computing-heavy workstations, and is therefore a good fit for GIS specific requirements.

See: https://wiki.osgeo.org/wiki/Enterprise_Linux_GIS

===== Scientific Linux =====

See Centos

===== CentOS =====

You first need to add the EPEL repository for PROJ and GDAL, see [https://fedoraproject.org/wiki/EPEL/FAQ#How_can_I_install_the_packages_from_the_EPEL_software_repository.3F here]

'''GRASS 8 compilation and installation'''

[https://grass.osgeo.org/grass84/source/snapshot/ Download source code] (e.g., --> "Download latest 8.4 code)" and configure GRASS 8 (suggestion: save this as script):

./configure \
--with-cxx \
--with-proj --with-proj-share=/usr/share/proj \
--with-gdal=/usr/bin/gdal-config \
--with-sqlite \
--with-python \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype --with-freetype-includes=/usr/include/freetype2 \
--with-wxwidgets=/usr/bin/wx-config \
--with-openmp \
--with-blas --with-blas-includes=/usr/include/atlas-x86_64-base/ \
--with-lapack --with-lapack-includes=/usr/include/atlas-x86_64-base/ \
--with-fftw \
--with-geos \
--with-netcdf \
--without-ffmpeg \
--without-mysql \
--without-postgres \
--without-odbc \
--without-fftw

Compile:
make
or on a multicore system (number depends of available cores):
make -j4

For a system wide installation, run as root user:
make install
OR simply run it directly from the source code directory (substitute ARCH with i686 or x86_64):

bin.$ARCH/grass -gui

In this case, for convenience, add it to the search path:
mkdir $HOME/bin
cd $HOME/bin
# example:
ln -s $HOME/software/grass84_release/bin.x86_64-pc-linux-gnu/grass .

Now use it subsequently with
grass -gui

'''Installation grass on a HPC system with '''Centos 7''' and no root privileges:'''

This assumes that python3, fftw, proj, gdal and geos are available on the HPC system, either as modules or as installed software.

Download and prepare some dependencies (freetypes and zstd)
mkdir -p $HOME/grass/freetypes
cd $HOME/grass/freetypes
wget path/to/freetype-2.9.1.tar.gz
tar -xf freetype-2.9.1.tar.gz

mkdir $HOME/grass/zstd
cd mkdir $HOME/grass/zstd
wget path/to/v1.4.4/zstd-1.4.4.tar.gz
tar -xf zstd-1.4.4.tar.gz
make install PREFIX=./

Add the ZSTD path to your LD_LIBRARY_PATH

tee -a $HOME/.bashrc > /dev/null << EOT
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/grass/zstd/zstd-1.4.4/lib
EOT

The configure command could look like this
./configure \
-prefix=$HOME/grass \
--enable-64bit --with-fftw-includes=/path/to/fftw/include/ \
--with-fftw-libs=/path/to/fftw/lib/ \
--with-freetype-includes=$HOME/grass/freetypes/freetype-2.9.1/include/ \
--with-netcdf --with-geos --with-blas --with-lapack --with-postgres \
--with-zstd-includes=$HOME/grass/zstd/zstd-1.4.4/lib/ \
--with-zstd-libs=$HOME/grass/zstd/zstd-1.4.4/lib/ \
--with-gdal=/path/to/gdal-config # This could be the path to a gdal version compiled from source

Finally as usual:
make; make install

====== GRASS 8 on Fedora ======

'''Preparation''' for the compilation of GRASS 8+ source code (F36+):

dnf install gcc gcc-c++ bison flex ncurses-devel gettext proj-devel \
gdal gdal-devel sqlite-devel xml2 mesa-libGL-devel cairo-devel \
fftw-devel mesa-libGLU-devel libXmu-devel libX11-devel geos geos-devel \
libtiff-devel python3-devel numpy wxGTK-devel gawk git \
python3-dateutil python3-imaging python3-matplotlib-wx doxygen python3-sphinx \
libzstd-devel libzstd python3-six python3-numpy python3-wxpython4 \
proj-data PDAL-devel PDAL-libs

# optionally also: netcdf-devel postgresql-devel
# atlas-devel lapack-devel lapack-devel
# laszip laszip-devel
# proj-data-at proj-data-au proj-data-be ...

''Note 1: the optional ffmpeg-devel comes from the rpmfusion-free repository ([https://rpmfusion.org/Configuration/ configuration]).''

'''Download''' and unpack the source code:
* GRASS 8: [https://grass.osgeo.org/grass84/source/snapshot/ weekly snapshot] - [https://github.com/OSGeo/grass/releases GitHub repository]

'''Configure''': This is an example how to configure the source code on a Fedora system:

./configure \
--with-cxx \
--with-gdal=/usr/bin/gdal-config \
--with-proj --with-proj-share=/usr/share/proj \
--with-geos \
--with-pdal \
--with-sqlite \
--with-nls \
--with-wxwidgets=/usr/bin/wx-config \
--with-fftw \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype --with-freetype-includes=/usr/include/freetype2 \
--enable-largefile \
--without-odbc

''Extra 1:'' If you also want '''FFMPEG support''' - it requires 'dnf install fftw-devel' from the rpmfusion-free repository. Then add to the configuration lines above:

--with-ffmpeg --with-ffmpeg-includes="/usr/include/ffmpeg /usr/include/ffmpeg/libav* /usr/include/ffmpeg/libpostproc /usr/include/ffmpeg/libswscale" \

''Extra 2:'' For '''LAPACK/BLAS support''' (addons i.spec.unmix, v.kriging etc), install "dnf install lapack lapack-devel blas blas-devel atlas atlas-devel". Then add to the configuration lines above:
--with-blas --with-blas-includes=/usr/include/atlas-x86_64-base/ \
--with-lapack --with-lapack-includes=/usr/include/atlas-x86_64-base/ \

''Extra 3:'' For '''ZSTD support''' (Zstandard compression algorithm), first install "dnf install libzstd libzstd-devel zstd". After installing the zstd related packages, add to the configuration lines above:
--with-zstd \

Finally '''compile''' the configured source code:
make
or on multicore (number depends of available cores):
make -j4
and
make install # requires root permissions unless you become owner of /usr/local/

Then use GRASS 8 and enjoy!

grass --version

==== macOS ====

Compiling GRASS for macOS is not fundamentally different from for other *nix systems. It is on the contrary quite similar, but what differ is the lack of a default package management system for software GRASS depends on. This leaves the mac user to either: (1) compile the dependencies one-by-one; (2) compiling with one of the third-party package management systems avaliable; or (4) a combination thereof.

If you are interested in installing a precompiled version, please check out the [https://grass.osgeo.org/download/software/mac-osx/ official download site].

To date, maybe the easiest way to compile for Mac is by using [https://github.com/nilason/grass-conda GRASS app build script] which is based on the instructions below for building using Anaconda. It will install dependencies, package and install an app bundle with just a command in Terminal.

===== Compilation and installation =====

For more up-to-date instructions please read:

* [https://github.com/nilason/grass-conda Compiling on macOS using Conda] (Intel / Apple silicon based machine M1)
* [[Compiling on macOS using Anaconda]]
* [[Compiling on macOS using Homebrew]]
* [[Compiling on macOS using MacPorts]]

===== Legacy instructions =====

The following compilation and installation instructions are rather outdated as a whole. They do, however, contain parts and snippets that still may be very instructive and useful.

* [[Compiling on MacOSX]]
* [[Compiling on MacOSX using Fink]]
* [https://web.archive.org/web/20180718005252/https://www.kyngchaos.com/software/frameworks#build_scripts build scripts for dependencies]

Troubleshooting:
* solving errors at starting GRASS: [[MacOSX GRASS errors]]

==== FreeBSD / NetBSD ====

The recommended compiler tools are GCC, GNU make, GNU coreutils (for install), and flex. All are available through the respective package managing tools (pkg_add for FreeBSD and pkgin install for NetBSD) and for recent *BSD versions most likely installed by default.

GRASS 8 should compile on FreeBSD and NetBSD.

It is highly recommended to install GDAL/OGR and PROJ first. These libraries and tools are available as [https://www.freebsd.org/ports/ ports for FreeBSD] and [https://www.pkgsrc.org/ packages for NetBSD].

Optional functionality is listed with ''./configure --help'', and related libraries and tools might need to be installed first.

You then may need to edit include/Make/Platform.make and set
ICONVLIB = -liconv

==== AIX ====

A recent [ftp://ftp.gnu.org/gnu/make/ GNU make] (>= 3.81) and GNU coreutils are required. These are available with the [https://www-03.ibm.com/systems/power/software/aix/linux/toolbox/download.html IBM AIX toolbox] or through third-party AIX software repositories, e.g. [https://www.bullfreeware.com/ bullfreeware] and [https://www.perzl.org/aix/ perzl.org]. Note that 'make' does not work, only 'gmake' works.

General instructions to compile on AIX are e.g. [https://www.perzl.org/aix/index.php?n=Main.Instructions here]

On AIX, compilation results by default in 32 bit applications and static libraries. The [https://developer.ibm.com/components/aix/ IBM documentation] explains how to build 64 bit applications and shared libraries with GCC.

'''GRASS 8: Using the IBM xlc compiler:'''

==== MS-Windows ====

See also [[WinGRASS Current Status]] for latest updates.

===== MS-Windows/native =====

GRASS on Windows using a standalone installer. It is still MinGW based (we are going to move this to CMake in 2024+).

Instructions to compile from source code:
* [https://trac.osgeo.org/grass/wiki/CompileOnWindows GRASS Windows Native Binary Building Guide]

===== MS-Windows/OSGeo4W =====

OSGeo4W is an installer for a broad set of open source geospatial software packages including GRASS as well as many other packages (QGIS, GDAL/OGR, and more).

* See [https://trac.osgeo.org/osgeo4w/ OSGeo4W]

===== MS-Windows/Cygwin =====

* See the [[Cygwin]] wiki pages

=== Common problems and solutions ===

During compilation, error can occur if certain packages are not installed. Here a list of problems with solution:

* error: X11/Xlib.h: No such file or directory
** this suggests that you don't have the X headers installed
** Solution: Install the libx11-dev package

* error: g.list: error while loading shared libraries: libgdal1.6.0.so.1: cannot open shared object file: No such file or directory
** this error appears in the shell right after the user clicks GUI's "Start GRASS" button. The GUI shows an error about geographic extent and gets closed afterwards.
** It happens when you launch bin.i686 executable on 64bit system. Be careful and choose the right architecture.

* error: lib/python/ctypes
** This error appears during the compilation: <code>free(): invalid pointer Aborted (core dumped)</code>
** It happens when you have multiple <code>libproj</code> versions on your system (check it with command <code>ldd PATH_TO_GRASS_INSTALL/lib/libgrass_gproj.so | grep proj</code> - when this is not your problem, you should obtain exactly one result)
** Solution: Try to reinstall <code>libproj-dev</code> and <code>proj-data</code>

=== Static compilation ===

In order to get static rather than dynamically linked binaries, configure like this:

./configure --disable-shared --enable-static

This will however break the wxGUI and GRASS 8 completely because "ctypes" wants to link against shared libs, or there is something in the static libs that "ctypes" does not like.

=== Optimization ===

GCC and other compilers support [https://gcc.gnu.org/onlinedocs/gcc-4.3.3/gcc/Optimize-Options.html#Optimize-Options optimization]

If you would like to set compiler optimisations, for a possibly faster binary, type (don't enter a ";" anywhere):

CFLAGS=-O ./configure
or,
setenv CFLAGS -O
./configure

whichever works on your shell. Use -O2 instead of -O if your compiler supports this (note: O is the letter, not zero). Using the "gcc" compiler, you can also specify processor specific flags (examples, please suggest better settings to us):

CFLAGS="-mcpu=athlon -O2" # AMD Athlon processor with code optimisations
CFLAGS="-march=amdfam10" # AMD Phenom II X4 64bit processor with gcc >=4.3
CFLAGS="-mcpu=pentium" # Intel Pentium processor
CFLAGS="-mcpu=pentium4" # Intel Pentium4 processor
CFLAGS="-O2 -msse -msse2 -mfpmath=sse -minline-all-stringops" # Intel XEON 64bit processor
CFLAGS="-mtune=nocona -m64 -minline-all-stringops" # Intel Pentium 64bit processor

To find out optional CFLAGS for your platform, enter:
gcc -dumpspecs

See also: https://gcc.gnu.org/

A real fast GRASS version (and small binaries) will be created with LDFLAGS set to "stripping" (but this disables debugging):

CFLAGS="-O2 -mcpu=<cpu_see_above> -Wall" LDFLAGS="-s" ./configure

=== Configure options and their meanings ===

For configure there are many options and some GRASS modules are built only if some options are set. Here are listed common configuration options with short explanation.

* --prefix=/path - Sets path where GRASS will be installed. GRASS will reside in /path/grass-version.
* --enable-largefile - Enables large (>2Gb on 32bit systems) support. For current large file support status look at [[Large File Support]] page.
* --with-cxx - Enables compilation of C++ code. Required for r.terraflow module.
* --with-readline - Enables readline support. If readline is enabled, you can use its history/editing facilities when entering r.mapcalc expressions on stdin.
* --with-glw - Enables GLw support. The GLw library provides OpenGL "canvas" widgets for Athena and Motif.

That switch is unnecessary for normal compilation. It's only
required for r3.showdspf, which isn't normally built; if you
want it, you have build it manually
(e.g. "make -C raster3d/r3.showdspf").
As similar functionality is now provided by NVIZ, r3.showdspf
is deprecated.
r3.showdspf uses the Motif widget (so you also need a
Motif library, e.g. Lesstif or OpenMotif).
[https://grass.itc.it/pipermail/grassuser/2006-December/037475.html Glynn Clements at GRASS-user mailing list]

=== Parallelized compilation on multi-core CPUs ===

You can dramatically accelerate the compilation of the GRASS code with the -j flag of "make" if you have a multi-core CPU system. This determines the maximum number of jobs to have running at once, so cores don't have to sit idle waiting for jobs on other cores to complete. A good rule of thumb for this value is <tt>number_of_cores * 1.5</tt>, but note that setting any higher than the actual number of cores will only affect the timing slightly. For example, on a dual-core processor:
make -j 4



== GRASS-GDAL plugin ==

* see [[Compile and install GRASS and QGIS with GDAL/OGR Plugin]]

== Addons ==

Please note that the installation of [https://grass.osgeo.org/grass-stable/manuals/addons/ GRASS addons] can be easily done with the {{cmd|g.extension}} manager. The compile instructions below are aiming at own development.

=== Compiled modules ===

This is the general way which works for C modules as well as scripts (Python or Shell/Bash modules) which has HTML documentation.

'''Requirements:'''

Either:
* a binary GRASS package, or
* source code which has been prepared with:
./configure [opionally flags]
make libs

Each of the [[GRASS_AddOns|addon]] modules should come with a Makefile. To compile it, just run:
make MODULE_TOPDIR=/path/to/grass84/

Note that the <tt>/path/to/grass84</tt> has to be absolute, not relative.

If using Bash it may be useful to set that up as an alias:
alias gmake64='make MODULE_TOPDIR=/path/to/grass84/'

Installation (perhaps requires "sudo"):
make MODULE_TOPDIR=/path/to/grass84/ install

Note: Compiled addons may require a re-compilation if you changed/updated your GRASS standard binaries.

==== If binary comes with a -dev package ====

''(work in progress, this text states how it eventually will be :)''
Nowadays one does not need to the source code, nor compiling GRASS by oneself to be able to add add-ons. On Debian, you can just install the grass-dev package and then run:
make MODULE_TOPDIR=/usr/lib/grass84/ INST_DIR=/usr/lib/grass84/

The grass-dev package essentially provides GRASS's <tt>include</tt> header files and Make configuration files.

=== Scripts ===

If the addon module is a script, it is sufficient to copy it into the (GRASS binaries) path somewhere. Alternatively, install addons into a separate GRASS addons binaries/scripts directory which is easier to maintain. It avoids getting clobbered every time you reinstall GRASS. To use these separately stored scripts, set and export the GRASS_ADDON_PATH environment variable before starting GRASS and it will automatically be added to the module search path (see the {{cmd|variables}} help page). To simplify this, do for example:

# add in $HOME/.bashrc:
GRASS_ADDON_PATH=/usr/local/grass/addons/
export GRASS_ADDON_PATH

Make sure that the script is executable, then just call it in GRASS typing the filename. Python scripts need to be called writing the extension as well, like:

GRASS (nc_spm):~ > v.krige.py

Compile and Install

2026-03-27T16:27:31Z

Neteler: Linux Mint 22: fix wxpython version, subversion -> git

'''Disclaimer''': This page explains how to turn the GRASS source code into an installable binary package ("compilation") for different operating systems. If you just want to get ready-to-use binaries, go [https://grass.osgeo.org/download/ here], otherwise read on...

== How to do compilation and installation of GRASS? ==

Here we explain the procedure to compile GRASS from GitHub, but it also applies to official GRASS 8 releases.

''For installation of precompiled binary packages, see the main [[Installation Guide]].''

For detailed information on compilation, please see the [https://github.com/OSGeo/grass/blob/main/INSTALL.md INSTALL] file in the source code.

=== Prerequisites ===

==== Extra libraries ====
GRASS needs at least two extra libraries: PROJ and GDAL/OGR. It is recommended to download them as ready-to-use packages for your software platform (Linux distribution, Windows, Mac...).

Other libraries needed to run GRASS are listed on the [https://github.com/OSGeo/grass/blob/main/REQUIREMENTS.md requirements page].

To compile, you will also need the respective "-devel" packages; see below for details.

==== Download GRASS source code ====

First, [https://grass.osgeo.org/download/ download the GRASS source code].

=== Generic Compilation and installation procedure ===

* It is wise that compilation processes are carried out as a normal user: If you want to get the source code in a place where you do not have write permissions (e.g. in /usr/local/src/) just follow this:
cd /usr/local/src/
su -c 'mkdir grass8'
su -c 'chown yourlogin:yourgroup grass8'

Otherwise if you have permissions just continue as a normal user:
mkdir $HOME/src
cd $HOME/src/
git clone https://github.com/OSGeo/grass.git grass_main

* run configure with parameters to adapt the compile process to your own system. To see what options can be passed to it, run:
./configure --help | less


It may (!) look like this:

./configure \
--with-cxx \
--with-sqlite \
--with-python \
--with-geos \
--with-gdal=/usr/bin/gdal-config \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype \
--with-freetype-includes=/usr/include/freetype2 \
--with-proj --with-proj-share=/usr/share/proj

You may have to explicitly state the path for certain packages (i.e., gdal). The Unix 'locate' command will come in handy for finding the path of the package you need (you may have to run locate as root ex: sudo locate gdal-config).

Please note that the paths mentioned may widely vary due to the distribution used.
See [[Compile_and_Install#Platform_Specific_Notes|Platform Specific Notes]] below.

Depending on your needs it may be a good idea to include debugging hooks.
: See [[GRASS_Debugging#Compile_Time_Setup]].
CFLAGS="-ggdb -Wall -Werror-implicit-function-declaration" ./configure ...

At the end of configuration process you should get report not much different from this:

GRASS is now configured for: x86_64-pc-linux-gnu

Source directory: /home/user/software/grass_main
Build directory: /home/user/software/grass_main

(In case of errors please change into the directory with error and run 'make')

* If there is any error, change directory to directory with error and run "make" again. Report occurring bug to GRASS mailing list
* Once the installation process is finished, you're ready to install GRASS system wide.
su -c 'make install'
* enjoy GRASS:
grass

=== What else? ===

If you want to use [https://www.qgis.org QGIS], then also compile the GRASS-GDAL/OGR plugin. This is also useful to access your GRASS-data
from other application using GDAL/OGR like [[R_statistics/ R]].
* [[Compile and install GRASS and QGIS with GDAL/OGR Plugin]] (enables QGIS to read GRASS data directly)

===== Archlinux =====
You can install GRASS for Archlinux distribution based like Archlinux, Manjaro, EndeavourOS ...

* <big>'''Easiest method : use a prebuilt package using arch4edu repository'''</big>
''"Arch4edu is a community repository for Arch Linux and Arch Linux ARM that strives to provide the latest versions of most software used by college students."''

1. Add Arch4edu repository. Follow instructions from official documentation:

https://github.com/arch4edu/arch4edu/wiki/Add-arch4edu-to-your-Archlinux

2. Refresh packages list with

pacman -Syyu

3. Install GRASS package

pacman -S grass

* <big>'''Advanced method : use AUR (Arch User Repository) package'''</big>
Up-to-date links to Archlinux GRASS PKGBUILDs are on Arch User Repository.
PKGBUILD downloads and builds automatically sources from https://grass.osgeo.org/download/software/linux/.

You can use an AUR helper like ''pamac'', ''yay'', among others ... More info through this link https://wiki.archlinux.org/title/AUR_helpers

Exemple with ''yay'':
yay -S grass

* <big>'''Expert method : compile from source code'''</big>
If you want to compile it yourself, you could follow steps below :

''(As an alternative it is recommended to download PKGBUILD from AUR and then customize to your needs)''

Install dependencies :
pacman -S bzip2 cairo fftw fontconfig freetype2 gcc-libs gdal geos glibc glu libpng libtiff libx11 libgl netcdf pdal proj python-gdal python-numpy python-pillow python-wxpython readline zlib zstd

Download and extract sources : https://grass.osgeo.org/download/software/sources/

We can now start building GRASS

export PATH=~/usr/bin:$PATH && \
./configure \
--with-freetype-includes=/usr/include/freetype2 \
--with-wxwidgets \
--with-readline \
--with-pthread \
--with-netcdf \
--with-nls \
--with-geos \
--with-postgres \
--with-pdal=/usr/include/pdal \
--with-bzlib \
--with-zstd

Now let's compile and install it

make
make install

It's done, you can enjoy GRASS in Arch, just type "grass" in the terminal to launch it or look for grass in your menu.

===== Generic procedure for Debian-based distributions (Ubuntu, ...) =====

WORK IN PROGRESS

1. Install official GRASS package

sudo apt install grass grass-dev

2. Enable source code download

Enterprise Linux (EL) and derivatives (that is, Red Hat Enterprise Linux, CentOS and Scientific Linux) is a popular and robust platform for servers and computing-heavy workstations, and is therefore a good fit for GIS specific requirements.

See: https://wiki.osgeo.org/wiki/Enterprise_Linux_GIS

===== Scientific Linux =====

See Centos

===== CentOS =====

You first need to add the EPEL repository for PROJ and GDAL, see [https://fedoraproject.org/wiki/EPEL/FAQ#How_can_I_install_the_packages_from_the_EPEL_software_repository.3F here]

'''GRASS 8 compilation and installation'''

[https://grass.osgeo.org/grass84/source/snapshot/ Download source code] (e.g., --> "Download latest 8.4 code)" and configure GRASS 8 (suggestion: save this as script):

./configure \
--with-cxx \
--with-proj --with-proj-share=/usr/share/proj \
--with-gdal=/usr/bin/gdal-config \
--with-sqlite \
--with-python \
--with-cairo --with-cairo-ldflags=-lfontconfig \

--with-fftw \
--with-geos \
--with-netcdf \
--without-ffmpeg \
--without-mysql \
--without-postgres \
--without-odbc \
--without-fftw

Compile:
make
or on a multicore system (number depends of available cores):
make -j4

For a system wide installation, run as root user:
make install
OR simply run it directly from the source code directory (substitute ARCH with i686 or x86_64):

bin.$ARCH/grass -gui

In this case, for convenience, add it to the search path:
mkdir $HOME/bin
cd $HOME/bin
# example:
ln -s $HOME/software/grass84_release/bin.x86_64-pc-linux-gnu/grass .

Now use it subsequently with
grass -gui

'''Installation grass on a HPC system with '''Centos 7''' and no root privileges:'''

This assumes that python3, fftw, proj, gdal and geos are available on the HPC system, either as modules or as installed software.

Download and prepare some dependencies (freetypes and zstd)
mkdir -p $HOME/grass/freetypes
cd $HOME/grass/freetypes
wget path/to/freetype-2.9.1.tar.gz
tar -xf freetype-2.9.1.tar.gz

mkdir $HOME/grass/zstd
cd mkdir $HOME/grass/zstd
wget path/to/v1.4.4/zstd-1.4.4.tar.gz
tar -xf zstd-1.4.4.tar.gz
make install PREFIX=./

Add the ZSTD path to your LD_LIBRARY_PATH

tee -a $HOME/.bashrc > /dev/null << EOT
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/grass/zstd/zstd-1.4.4/lib
EOT

The configure command could look like this
./configure \
-prefix=$HOME/grass \
--enable-64bit --with-fftw-includes=/path/to/fftw/include/ \
--with-fftw-libs=/path/to/fftw/lib/ \
--with-freetype-includes=$HOME/grass/freetypes/freetype-2.9.1/include/ \

--with-zstd-includes=$HOME/grass/zstd/zstd-1.4.4/lib/ \
--with-zstd-libs=$HOME/grass/zstd/zstd-1.4.4/lib/ \
--with-gdal=/path/to/gdal-config # This could be the path to a gdal version compiled from source

Finally as usual:
make; make install

''Note 1: the optional ffmpeg-devel comes from the rpmfusion-free repository ([https://rpmfusion.org/Configuration/ configuration]).''

'''Download''' and unpack the source code:
* GRASS 8: [https://grass.osgeo.org/grass84/source/snapshot/ weekly snapshot] - [https://github.com/OSGeo/grass/releases GitHub repository]

'''Configure''': This is an example how to configure the source code on a Fedora system:

./configure \
--with-cxx \
--with-gdal=/usr/bin/gdal-config \
--with-proj --with-proj-share=/usr/share/proj \
--with-geos \
--with-pdal \
--with-sqlite \
--with-nls \
--with-wxwidgets=/usr/bin/wx-config \
--with-fftw \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype --with-freetype-includes=/usr/include/freetype2 \
--enable-largefile \
--without-odbc

''Extra 1:'' If you also want '''FFMPEG support''' - it requires 'dnf install fftw-devel' from the rpmfusion-free repository. Then add to the configuration lines above:

--with-ffmpeg --with-ffmpeg-includes="/usr/include/ffmpeg /usr/include/ffmpeg/libav* /usr/include/ffmpeg/libpostproc /usr/include/ffmpeg/libswscale" \

''Extra 2:'' For '''LAPACK/BLAS support''' (addons i.spec.unmix, v.kriging etc), install "dnf install lapack lapack-devel blas blas-devel atlas atlas-devel". Then add to the configuration lines above:
--with-blas --with-blas-includes=/usr/include/atlas-x86_64-base/ \
--with-lapack --with-lapack-includes=/usr/include/atlas-x86_64-base/ \

''Extra 3:'' For '''ZSTD support''' (Zstandard compression algorithm), first install "dnf install libzstd libzstd-devel zstd". After installing the zstd related packages, add to the configuration lines above:
--with-zstd \

Finally '''compile''' the configured source code:
make
or on multicore (number depends of available cores):
make -j4
and
make install # requires root permissions unless you become owner of /usr/local/

Then use GRASS 8 and enjoy!

==== macOS ====

Compiling GRASS for macOS is not fundamentally different from for other *nix systems. It is on the contrary quite similar, but what differ is the lack of a default package management system for software GRASS depends on. This leaves the mac user to either: (1) compile the dependencies one-by-one; (2) compiling with one of the third-party package management systems avaliable; or (4) a combination thereof.

If you are interested in installing a precompiled version, please check out the [https://grass.osgeo.org/download/software/mac-osx/ official download site].

To date, maybe the easiest way to compile for Mac is by using [https://github.com/nilason/grass-conda GRASS app build script] which is based on the instructions below for building using Anaconda. It will install dependencies, package and install an app bundle with just a command in Terminal.

===== Compilation and installation =====

For more up-to-date instructions please read:

* [https://github.com/nilason/grass-conda Compiling on macOS using Conda] (Intel / Apple silicon based machine M1)
* [[Compiling on macOS using Anaconda]]
* [[Compiling on macOS using Homebrew]]
* [[Compiling on macOS using MacPorts]]

===== Legacy instructions =====

The following compilation and installation instructions are rather outdated as a whole. They do, however, contain parts and snippets that still may be very instructive and useful.

* [[Compiling on MacOSX]]
* [[Compiling on MacOSX using Fink]]
* [https://web.archive.org/web/20180718005252/https://www.kyngchaos.com/software/frameworks#build_scripts build scripts for dependencies]

Troubleshooting:
* solving errors at starting GRASS: [[MacOSX GRASS errors]]

==== FreeBSD / NetBSD ====

The recommended compiler tools are GCC, GNU make, GNU coreutils (for install), and flex. All are available through the respective package managing tools (pkg_add for FreeBSD and pkgin install for NetBSD) and for recent *BSD versions most likely installed by default.

GRASS 8 should compile on FreeBSD and NetBSD.

It is highly recommended to install GDAL/OGR and PROJ first. These libraries and tools are available as [https://www.freebsd.org/ports/ ports for FreeBSD] and [https://www.pkgsrc.org/ packages for NetBSD].

Optional functionality is listed with ''./configure --help'', and related libraries and tools might need to be installed first.

You then may need to edit include/Make/Platform.make and set
ICONVLIB = -liconv

==== AIX ====

A recent [ftp://ftp.gnu.org/gnu/make/ GNU make] (>= 3.81) and GNU coreutils are required. These are available with the [https://www-03.ibm.com/systems/power/software/aix/linux/toolbox/download.html IBM AIX toolbox] or through third-party AIX software repositories, e.g. [https://www.bullfreeware.com/ bullfreeware] and [https://www.perzl.org/aix/ perzl.org]. Note that 'make' does not work, only 'gmake' works.

General instructions to compile on AIX are e.g. [https://www.perzl.org/aix/index.php?n=Main.Instructions here]

On AIX, compilation results by default in 32 bit applications and static libraries. The [https://developer.ibm.com/components/aix/ IBM documentation] explains how to build 64 bit applications and shared libraries with GCC.

'''GRASS 8: Using the IBM xlc compiler:'''

==== MS-Windows ====

See also [[WinGRASS Current Status]] for latest updates.

===== MS-Windows/native =====

GRASS on Windows using a standalone installer. It is still MinGW based (we are going to move this to CMake in 2024+).

Instructions to compile from source code:
* [https://trac.osgeo.org/grass/wiki/CompileOnWindows GRASS Windows Native Binary Building Guide]

===== MS-Windows/OSGeo4W =====

OSGeo4W is an installer for a broad set of open source geospatial software packages including GRASS as well as many other packages (QGIS, GDAL/OGR, and more).

* See [https://trac.osgeo.org/osgeo4w/ OSGeo4W]

===== MS-Windows/Cygwin =====

* See the [[Cygwin]] wiki pages

=== Common problems and solutions ===

During compilation, error can occur if certain packages are not installed. Here a list of problems with solution:

* error: X11/Xlib.h: No such file or directory
** this suggests that you don't have the X headers installed
** Solution: Install the libx11-dev package

* error: g.list: error while loading shared libraries: libgdal1.6.0.so.1: cannot open shared object file: No such file or directory
** this error appears in the shell right after the user clicks GUI's "Start GRASS" button. The GUI shows an error about geographic extent and gets closed afterwards.
** It happens when you launch bin.i686 executable on 64bit system. Be careful and choose the right architecture.

* error: lib/python/ctypes
** This error appears during the compilation: <code>free(): invalid pointer Aborted (core dumped)</code>
** It happens when you have multiple <code>libproj</code> versions on your system (check it with command <code>ldd PATH_TO_GRASS_INSTALL/lib/libgrass_gproj.so | grep proj</code> - when this is not your problem, you should obtain exactly one result)
** Solution: Try to reinstall <code>libproj-dev</code> and <code>proj-data</code>

=== Static compilation ===

In order to get static rather than dynamically linked binaries, configure like this:

./configure --disable-shared --enable-static

This will however break the wxGUI and GRASS 8 completely because "ctypes" wants to link against shared libs, or there is something in the static libs that "ctypes" does not like.

=== Optimization ===

GCC and other compilers support [https://gcc.gnu.org/onlinedocs/gcc-4.3.3/gcc/Optimize-Options.html#Optimize-Options optimization]

If you would like to set compiler optimisations, for a possibly faster binary, type (don't enter a ";" anywhere):

CFLAGS=-O ./configure
or,
setenv CFLAGS -O
./configure

whichever works on your shell. Use -O2 instead of -O if your compiler supports this (note: O is the letter, not zero). Using the "gcc" compiler, you can also specify processor specific flags (examples, please suggest better settings to us):

CFLAGS="-mcpu=athlon -O2" # AMD Athlon processor with code optimisations
CFLAGS="-march=amdfam10" # AMD Phenom II X4 64bit processor with gcc >=4.3
CFLAGS="-mcpu=pentium" # Intel Pentium processor
CFLAGS="-mcpu=pentium4" # Intel Pentium4 processor
CFLAGS="-O2 -msse -msse2 -mfpmath=sse -minline-all-stringops" # Intel XEON 64bit processor
CFLAGS="-mtune=nocona -m64 -minline-all-stringops" # Intel Pentium 64bit processor

To find out optional CFLAGS for your platform, enter:
gcc -dumpspecs

See also: https://gcc.gnu.org/

A real fast GRASS version (and small binaries) will be created with LDFLAGS set to "stripping" (but this disables debugging):

CFLAGS="-O2 -mcpu=<cpu_see_above> -Wall" LDFLAGS="-s" ./configure

=== Configure options and their meanings ===

For configure there are many options and some GRASS modules are built only if some options are set. Here are listed common configuration options with short explanation.

* --prefix=/path - Sets path where GRASS will be installed. GRASS will reside in /path/grass-version.
* --enable-largefile - Enables large (>2Gb on 32bit systems) support. For current large file support status look at [[Large File Support]] page.
* --with-cxx - Enables compilation of C++ code. Required for r.terraflow module.
* --with-readline - Enables readline support. If readline is enabled, you can use its history/editing facilities when entering r.mapcalc expressions on stdin.
* --with-glw - Enables GLw support. The GLw library provides OpenGL "canvas" widgets for Athena and Motif.

That switch is unnecessary for normal compilation. It's only
required for r3.showdspf, which isn't normally built; if you
want it, you have build it manually
(e.g. "make -C raster3d/r3.showdspf").
As similar functionality is now provided by NVIZ, r3.showdspf
is deprecated.
r3.showdspf uses the Motif widget (so you also need a
Motif library, e.g. Lesstif or OpenMotif).
[https://grass.itc.it/pipermail/grassuser/2006-December/037475.html Glynn Clements at GRASS-user mailing list]

=== Parallelized compilation on multi-core CPUs ===

You can dramatically accelerate the compilation of the GRASS code with the -j flag of "make" if you have a multi-core CPU system. This determines the maximum number of jobs to have running at once, so cores don't have to sit idle waiting for jobs on other cores to complete. A good rule of thumb for this value is <tt>number_of_cores * 1.5</tt>, but note that setting any higher than the actual number of cores will only affect the timing slightly. For example, on a dual-core processor:
make -j 4



== GRASS-GDAL plugin ==

* see [[Compile and install GRASS and QGIS with GDAL/OGR Plugin]]

== Addons ==

Please note that the installation of [https://grass.osgeo.org/grass-stable/manuals/addons/ GRASS addons] can be easily done with the {{cmd|g.extension}} manager. The compile instructions below are aiming at own development.

=== Compiled modules ===

This is the general way which works for C modules as well as scripts (Python or Shell/Bash modules) which has HTML documentation.

'''Requirements:'''

Either:
* a binary GRASS package, or
* source code which has been prepared with:
./configure [opionally flags]
make libs

Each of the [[GRASS_AddOns|addon]] modules should come with a Makefile. To compile it, just run:
make MODULE_TOPDIR=/path/to/grass84/

Note that the <tt>/path/to/grass84</tt> has to be absolute, not relative.

If using Bash it may be useful to set that up as an alias:
alias gmake64='make MODULE_TOPDIR=/path/to/grass84/'

Installation (perhaps requires "sudo"):
make MODULE_TOPDIR=/path/to/grass84/ install

Note: Compiled addons may require a re-compilation if you changed/updated your GRASS standard binaries.

==== If binary comes with a -dev package ====

''(work in progress, this text states how it eventually will be :)''
Nowadays one does not need to the source code, nor compiling GRASS by oneself to be able to add add-ons. On Debian, you can just install the grass-dev package and then run:
make MODULE_TOPDIR=/usr/lib/grass84/ INST_DIR=/usr/lib/grass84/

The grass-dev package essentially provides GRASS's <tt>include</tt> header files and Make configuration files.

=== Scripts ===

If the addon module is a script, it is sufficient to copy it into the (GRASS binaries) path somewhere. Alternatively, install addons into a separate GRASS addons binaries/scripts directory which is easier to maintain. It avoids getting clobbered every time you reinstall GRASS. To use these separately stored scripts, set and export the GRASS_ADDON_PATH environment variable before starting GRASS and it will automatically be added to the module search path (see the {{cmd|variables}} help page). To simplify this, do for example:

# add in $HOME/.bashrc:
GRASS_ADDON_PATH=/usr/local/grass/addons/
export GRASS_ADDON_PATH

Make sure that the script is executable, then just call it in GRASS typing the filename. Python scripts need to be called writing the extension as well, like:

GRASS (nc_spm):~ > v.krige.py

Please, prefer pre-compiled packages over the manual way described below unless you know ''what'' and ''how'', you want to learn and help testing.'''</span>
</div>

== Quick instructions ==

These instructions should work fine on Ubuntu distributions:

=== Install geospatial dependencies ===

1. Install some dependencies (PROJ, GEOS, GDAL libraries) and the compiler tools <br />
(note: you need Python 3)

<source lang="bash">
# be sure to have an updated system
sudo apt update && sudo apt upgrade -y

# install PROJ
sudo apt install libproj-dev proj-data proj-bin unzip -y
</source>

<source lang="bash">
# optionally, install (selected) datum grid files
sudo apt-get install proj-data

# install GEOS
sudo apt install libgeos-dev -y

# install GDAL
sudo apt install libgdal-dev python3-gdal gdal-bin -y

## install PDAL (optional) - apparently unavailable on Ubuntu
#sudo apt install libpdal-dev pdal -y

# Python3 precedence over Python2 (which is end-of-life since 2019, so it should be the default anyway)
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1
</source>

Install compiler stuff and further dependencies.
Note: this is a single command, please copy-paste it entirely into the terminal:

=== Install further compilation dependencies (Ubuntu 24.04) ===

For Ubuntu 24.04, including wxPython packages for GUI support:

<source lang="bash">
# this is a single command, please copy-paste it entirely into the terminal:
sudo apt-get install \
build-essential \
flex make bison gcc libgcc-s1 g++ \
python3 python3-dev \
python3-dateutil libgsl-dev python3-numpy \
zlib1g-dev gettext \
libtiff-dev libpnglite-dev \
sqlite3 libsqlite3-dev \
libboost-thread-dev libboost-program-options-dev \
systemd-resolved \
git \
checkinstall \
cmake ccache \
python3-opengl libwxbase3.2-1t64 libwxgtk3.2-dev \
python3-wxgtk4.0 \
cairo-dock libcairo2-dev \
libpq-dev \
libfreetype-dev \
libfftw3-dev libfftw3-single3 libfftw3-double3 \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev \
libglu1-mesa-dev libxmu-dev \
ghostscript
</source>

For NVIZ on Ubuntu, to also have video support (optional):
<source lang="bash">
sudo apt-get install \
ffmpeg libavutil-dev \
libffmpegthumbnailer-dev \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev -y
</source>

=== Source code download ===
Now we have all "ingredients" readily installed on our system.

'''Source code download''':

There a two ways of getting the source code: either use a) the weekly snapshot (cannot be updated, or b) the source code from the GitHub repository (you can update your local copy easily in future):

'''a) Download of the weekly source code snapshot (not recommended):'''
<source lang="bash">
# download latest GRASS GIS 8.x stable release source code:
mkdir $HOME/src/
cd $HOME/src/
wget https://grass.osgeo.org/grass84/source/snapshot/grass-8.4.git_src_snapshot_latest.tar.gz

# Unpack source code package and remove tarball archive:
tar xvfz grass-8.4.git_src_snapshot_latest.tar.gz
rm -f grass-8.4.git_src_snapshot_latest.tar.gz

# rename source code directory (yes, with the questionmarks!)
mv grass-8.4.git_src_snapshot_20??_??_?? grass-8.4.latest
cd grass-8.4.latest/
</source>

'''b) Download of the current development version from GitHub (adopt the path below accordingly)'''

Note: to find the current version number (8_x), see https://github.com/OSGeo/grass/branches:

<source lang="bash">
sudo apt-get install git
git clone https://github.com/OSGeo/grass.git grass-8.4.latest.git
cd grass-8.4.latest.git/
git checkout releasebranch_8_4
</source>

=== Compilation ===
Now we can '''compile''' the source code in order to generate the GRASS GIS binaries:

<source lang="bash">
# "configure" source code for local machine (checks for CPU type etc):
MYCFLAGS='-O2 -fPIC -fno-common -fexceptions -std=gnu99 -fstack-protector -m64'
#MYCXXFLAGS=''
MYLDFLAGS='-Wl,--no-undefined -Wl,-z,now'

LDFLAGS="$MYLDFLAGS" CFLAGS="$MYCFLAGS" CXXFLAGS="$MYCXXFLAGS" ./configure \
--with-cxx \
--enable-largefile \
--with-proj --with-proj-share=/usr/share/proj \
--with-gdal=/usr/bin/gdal-config \
--with-python \
--with-geos \
--with-sqlite \
--with-nls \
--with-zstd \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-wxwidgets \
--with-fftw \
--with-openmp \
--with-opengl-libs=/usr/include/GL \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--without-pdal \
--without-netcdf \
--without-mysql \
--without-odbc \
--without-ffmpeg
</source>

Now compile the source code (this will take some time as it generates binary code from the source code):
<source lang="bash">
# note: the more CPUs you have, the higher the -j number may be set to
# here: build using 4 CPU cores
make -j4
</source>

=== Installation ===

Install resulting GRASS GIS binaries into /usr/local/:
<source lang="bash">
sudo make install
</source>

Start GRASS GIS in the terminal:
<source lang="bash">
grass
</source>

'''Done & enjoy!'''

== Hints ==

* Usually, the installation of compiled code is done by using the <source lang="bash" enclose="none">make</source> tool. Alternatively, this can be done by using the ''checkinstall'' tool (i.e., <source lang="bash" enclose="none">sudo checkinstall</source> instead of <source lang="bash" enclose="none">sudo make install</source>) which eases off removal of packages. If ''checkinstall'' fails to deliver, please note some related bugs: [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/78455 78455] and [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/599163 599163]. Useful information on using ''checkinstall'': [https://help.ubuntu.com/community/CompilingEasyHowTo Compiling things on Ubuntu the Easy Way].

* In multi-core processors, the compilation performance can be boosted by using ''-j'' switches (e.g. <source lang="bash" enclose="none">make -j2</source> or <source lang="bash" enclose="none">make -j3</source> or even <source lang="bash" enclose="none">make -j4</source>) which specify the number of jobs (commands) to run simultaneously.

== Pre-compiled packages and backports ==

'''Pre-compiled packages and backports''' are available from [https://wiki.ubuntu.com/UbuntuGIS UbuntuGIS] via their [https://launchpad.net/~ubuntugis/+archive/ppa/ ppa.launchpad stable] and [https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable ppa.launchpad unstable] repositories. '''This is by far the simplest and fastest solution. Please prefer it over the manual way of compiling source code yourself as described below.'''

Version overview:
* jammy2 8.4
* noble 8.3
* jammy (22.04): 8.3
* focal (20.04 LTS): 8.2
* bionic (18.04 LTS): 7.8

a) Daily ready-to-install GRASS GIS builds of the stable release branch and master are available from ''ppa:grass/grass-devel'':

<source lang=bash>
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo add-apt-repository ppa:grass/grass-devel
</source>

b) Latest packaged stable version of GRASS GIS is available from ''ppa:grass/grass-stable'':

== Dependencies ==

=== Current stable Ubuntu version ===
First, update the system from the repositories<source lang="bash">
sudo apt-get update && sudo apt-get upgrade
</source>

Then, install ''SQLite'', ''git'' and ''dependencies'' for compiling PROJ, GEOS, GDAL/OGR, GRASS, GDAL-GRASS-PLUGIN (some additional packages may be required in this case); the following action will also install various dependencies (listed in the command line as <source lang="bash" enclose="none">The following extra packages will be installed:</source>...):<br/>

<source lang="bash">
# this is a single command, please copy-paste it entirely into the terminal:
sudo apt-get install \
build-essential \
flex make bison gcc libgcc1 g++ cmake ccache \
python python-dev \

ghostscript
</source>

* See the additional packages bellow and in other sections and install them. Note that some of them are [https://github.com/OSGeo/grass/blob/main/REQUIREMENTS.md required], namely PROJ, GEOS and GDAL. If you don't have special requirements, it is usually enough just to install PROJ, GEOS and GDAL from repository (rather then compile them manually).

* for mysql support, <source lang="bash" enclose="none">libmysqlclient-dev</source> is required
<source lang="bash">
sudo apt-get install libmysqlclient-dev
</source>

* for netcdf support, <source lang="bash" enclose="none">netcdf-bin</source> and <source lang="bash" enclose="none">libnetcdf-dev</source> is required
<source lang="bash">
sudo apt-get install netcdf-bin libnetcdf-dev
</source>

* for {{AddonCmd|i.spec.unmix}} Addon support, install LAPACK and BLAS:
<source lang="bash">
sudo apt-get install libblas-dev liblapack-dev
</source>

* create a directory as a simple user where all source code is going to be stored -- in this example, a directory named <source lang="bash" enclose="none">src</source> under <source lang="bash" enclose="none">/usr/local</source> is created <source lang="bash">
sudo mkdir /usr/local/src
</source>

* take over directories ownerships ('''replace''' below the terms ''userid'' and ''groupid'' with a real <source lang="bash" enclose="none">userid</source>): <source lang="bash">
sudo chown userid:groupid /usr/local/src</source>

* similarly, grant <source lang="bash" enclose="none">rwx</source> (read-write-execute) permissions for our ''userid'' and ''groupid'' onto the <source lang="bash" enclose="none">src</source> directory: <source lang="bash">
sudo chmod ug+rwx /usr/local/src</source>

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL ==

=== PROJ ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
sudo apt-get install libproj-dev proj-data proj-bin
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-proj-share=/usr/local/share/proj/</source> by <source lang="bash" enclose="none">--with-proj-share=/usr/share/proj/</source>

=== GEOS ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
# probably you also need to additionally install "libgeos-c1v5"
sudo apt-get install libgeos-dev
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-geos=/usr/local/bin/geos-config</source> by <source lang="bash" enclose="none">--with-geos=/usr/bin/geos-config</source>

=== GDAL ===

Install the <source lang="bash" enclose="none">dev</source> package (possibly without support for datumgrid):

<source lang="bash">
sudo apt-get install libgdal-dev
</source>

For support of WMS in wxGUI install Python GDAL bindings and GDAL executables:
<source lang="bash">
sudo apt-get install python-gdal gdal-bin
</source>

* Install also the required extra packages (note the message: <source lang="bash" enclose="none">The following extra packages will be installed:</source>)
* Look out for packages to be removed by this operation -- this is most likely caused by incompatible package versions. Fix these problems in advance using commands like the following: <source lang="bash">
sudo apt-get install <package>=<required.version></source>

=== GRASS-GIS ===

[[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]]

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL from GIS.lab PPA==

Ivan Mincik has made all required packages available in his [https://launchpad.net/~imincik/+archive/ubuntu/gis PPA]:

<source lang="bash">
sudo add-apt-repository ppa:imincik/gis
sudo apt-get install libproj-dev libgdal-dev python-gdal libgeos-dev
</source>

Now you can either also install GRASS GIS from there or compile it yourself (see [[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]])

== Compile from source ==

=== PROJ ===

* within the directory <source lang="bash" enclose="none">/usr/local/src</source> (create it if it does not exist) checkout <source lang="bash" enclose="none">proj</source> from its GitHub repository: <source lang="bash">
https://github.com/OSGeo/PROJ/
</source>

* get [http://download.osgeo.org/proj/proj-datumgrid-1.8.zip '''proj-datumgrid-1.8.zip'''] or related files from [https://trac.osgeo.org/proj proj' trac] and move it under <source lang="bash" enclose="none">proj/nad</source>
<ul><source lang="bash">
wget http://download.osgeo.org/proj/proj-datumgrid-1.8.zip
mv proj-datumgrid-1.8.zip /usr/local/src/proj/nad
cd /usr/local/src/proj/nad
</source>
</ul>

* decompress it <source lang="bash">
unzip proj-datumgrid-1.8.zip
</source>

* go back to the <source lang="bash" enclose="none">proj</source> directory <source lang="bash">
cd /usr/local/src/proj
</source>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* ensure that <source lang="bash" enclose="none">/usr/local/lib</source> is added to <source lang="bash" enclose="none">/etc/ld.so.conf</source> and afterwards run <source lang="bash">
sudo ldconfig
</source>

* finally, go back to the parent directory simply by instructing<source lang="bash">
cd ..
</source>

=== GEOS ===

* download '''geos-3.12.2.tar.bz2''' from [https://libgeos.org/ https://libgeos.org/] using <source lang="bash" enclose="none">wget</source> <source lang="bash">
wget https://download.osgeo.org/geos/geos-3.12.2.tar.bz2
</source>

* move to the "source-code" directory and decompress
<ul><source lang="bash">
cd /usr/local/src/
bunzip2 geos-3.12.2.tar.bz2
tar xvf geos-3.12.2.tar
</source>
</ul>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* move to geos directory <source lang="bash">
cd geos-3.12.2
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* do not forget to execute <source lang="bash">
sudo ldconfig
</source>

=== GDAL ===

'''Note''', GDAL must be compiled '''without''' GRASS support!

* download the current stable version (see https://github.com/OSGeo/gdal/releases for latest version):
<source lang="bash">
wget https://github.com/OSGeo/gdal/releases/download/v3.9.1/gdal-3.9.1.tar.gz
</source>

Follow the instructions to compile GDAL:
https://gdal.org/development/building_from_source.html

=== GRASS GIS ===

Note the differences between different GRASS GIS version (branches) in download and cofiguration. Note also the changes required if you installed some of the dependencies from packages (rather then compiled them yourself).

To fully understand the build process, read the <code>INSTALL</code> file, which is located in GRASS' source code root directory.

''' Getting GRASS' source code '''

Select from one of the GRASS GIS versions and download the source code:

https://github.com/OSGeo/grass/releases/

''' Configure, Compile and Install'''

Enter the directory with the source code, for example:

<source lang="bash">
cd grass
</source>

* '''GRASS GIS example configuration''' (which can/should be adjusted according to specific needs):
<ul>
<source lang="bash">
CFLAGS="-O2 -Wall" LDFLAGS="-s" ./configure \
--with-nls \
--with-cxx \
--with-proj-share=/usr/local/share/proj/ \
--with-geos=/usr/local/bin/geos-config \
--with-wxwidgets \
--with-cairo \
--with-opengl-libs=/usr/include/GL \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--with-sqlite=yes \
--with-mysql=yes --with-mysql-includes="/usr/include/mysql" \
--with-odbc=no \
--with-pdal
</source>
</ul>
<ul>
'''Note''', the above configuration uses the <code>PROJ</code> and <code>GEOS</code> packages compiled from the source. In the case that pre-compiled versions from the repository are required, remove the above corresponding lines to use the "defaults", i.e. (note the backslashe at the end of each line)
<source lang="bash">
--with-proj-share=/usr/share/proj \
--with-geos=/usr/bin/geos-config \
</source>
</ul>

* compile & install <source lang="bash">
make -j2 && sudo make install && sudo ldconfig
</source>

<ul> or <source lang="bash">
make -j2 && sudo checkinstall && sudo ldconfig
</source>
</ul>

For subsequent updates execute (not need for the first time):
<source lang="bash">
git pull
make -j2 && sudo make install && sudo ldconfig
</source>

Sometimes, it is required to clean previous configuration and compilation:
<source lang="bash">
make distclean
git pull
./configure ... # (use the configure command above)
make -j2 && sudo make install && sudo ldconfig
</source>

=== GDAL-GRASS-Plugin ===

See: https://github.com/OSGeo/gdal-grass

* get the plugin from [https://github.com/OSGeo/gdal-grass/releases GitHub]: "gdal-grass-X.Y.Z.tar.gz" using <source lang="bash" enclose="none">wget</source>
<ul><source lang="bash">
# update version number accordingly!
wget https://github.com/OSGeo/gdal-grass/archive/refs/tags/1.0.2.tar.gz -O gdal-grass-1.0.2.tar.gz
tar xvzf gdal-grass-1.0.2.tar.gz
cd gdal-grass-1.0.2
</source></ul>

* create <source lang="bash" enclose="none">/etc/ld.so.conf.d/grass.conf</source> or add in <source lang="bash" enclose="none">/etc/ld.so.conf</source> the GRASS library path:
<ul><source lang="bash">
# GRASS GIS stable library path (adapt as needed)
/usr/local/src/releasebranch_8_4/lib

# GRASS GIS development version library path (adapt as needed)
/usr/local/src/grass_master/lib
</source></ul>

* optionally, clean previous configurations/compilations<source lang="bash">
make distclean</source>

* configure -- point to GRASS installation/binaries
<ul><source lang="bash"> ./configure \
--prefix=/usr/local \
--with-gdal=/usr/local/bin/gdal-config \
--with-grass=/usr/local/grass/ \
--with-autoload="/usr/local/lib64/gdalplugins/" \
--with-ld-shared="g++ -shared"</source></ul>
</ul>

* compile & install using checkinstall<source lang="bash">
make -j2 && sudo checkinstall</source>

= Post compilation/installation control =

* For a recommended quick-check read the [https://grass.osgeo.org/wiki/Compile_and_install_GRASS_and_QGIS_with_GDAL/OGR_Plugin#Troubleshooting Troubleshooting] section at [https://grass.osgeo.org/wiki/Compile_and_install_GDAL-GRASS_plugin Compile_and_install_GDAL-GRASS_plugin]

* in case of errors in future compilation attempts, remember to remove program binaries and files created with the "configuration" from previous compilations with
make distclean

* another common mistake is compiling a module against some GRASS version and then try to run it through another GRASS version. The solution is to recompile the affected module or, in case there are multiple GRASS installations, set up properly LD_LIBRARY_PATH paths.

= Removal of GRASS =

To get rid of a GRASS binaries installation, delete (update version numbers accordingly)
* <source lang="bash" enclose="none">/usr/local/grass</source> (directory, binaries location)
* <source lang="bash" enclose="none">/usr/local/bin/grass</source> (file)
* <source lang="bash" enclose="none">/home/username/.grassrc8</source> (file)

If wanted, delete also the complete source code:
* <source lang="bash" enclose="none">/usr/local/src/grass_release</source> (directory, source code location)

To remove <code>grass</code> (or any other package) which was installed by <source lang="bash" enclose="none">checkinstall</source>, use <source lang="bash" enclose="none">dpkg</source>, e.g.<source lang="bash">
sudo dpkg -r grass # package name defined at installation is important</source>

libfftw3-dev libfftw3-single3 libfftw3-double3 \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev \
libglu1-mesa-dev libxmu-dev \
ghostscript
</source>

For NVIZ on Ubuntu, to also have video support (optional):
<source lang="bash">
sudo apt-get install \
ffmpeg libavutil-dev \
libffmpegthumbnailer-dev \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev -y
</source>

=== Source code download ===
Now we have all "ingredients" readily installed on our system.

'''Source code download''':

There a two ways of getting the source code: either use a) the weekly snapshot (cannot be updated, or b) the source code from the GitHub repository (you can update your local copy easily in future):

'''a) Download of the weekly source code snapshot (not recommended):'''
<source lang="bash">
# download latest GRASS GIS 8.x stable release source code:
mkdir $HOME/src/
cd $HOME/src/
wget https://grass.osgeo.org/grass84/source/snapshot/grass-8.4.git_src_snapshot_latest.tar.gz

# Unpack source code package and remove tarball archive:
tar xvfz grass-8.4.git_src_snapshot_latest.tar.gz
rm -f grass-8.4.git_src_snapshot_latest.tar.gz

# rename source code directory (yes, with the questionmarks!)
mv grass-8.4.git_src_snapshot_20??_??_?? grass-8.4.latest
cd grass-8.4.latest/
</source>

'''b) Download of the current development version from GitHub (adopt the path below accordingly)'''

Note: to find the current version number (8_x), see https://github.com/OSGeo/grass/branches:

<source lang="bash">
sudo apt-get install git
git clone https://github.com/OSGeo/grass.git grass-8.4.latest.git
cd grass-8.4.latest.git/
git checkout releasebranch_8_4
</source>

=== Compilation ===
Now we can '''compile''' the source code in order to generate the GRASS GIS binaries:

<source lang="bash">
# "configure" source code for local machine (checks for CPU type etc):
MYCFLAGS='-O2 -fPIC -fno-common -fexceptions -std=gnu99 -fstack-protector -m64'
#MYCXXFLAGS=''
MYLDFLAGS='-Wl,--no-undefined -Wl,-z,now'

LDFLAGS="$MYLDFLAGS" CFLAGS="$MYCFLAGS" CXXFLAGS="$MYCXXFLAGS" ./configure \
--with-cxx \
--enable-largefile \
--with-proj --with-proj-share=/usr/share/proj \
--with-gdal=/usr/bin/gdal-config \
--with-python \
--with-geos \
--with-sqlite \
--with-nls \
--with-zstd \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-wxwidgets \
--with-fftw \
--with-openmp \
--with-opengl-libs=/usr/include/GL \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--without-pdal \
--without-netcdf \
--without-mysql \
--without-odbc \
--without-ffmpeg
</source>

Now compile the source code (this will take some time as it generates binary code from the source code):
<source lang="bash">
# note: the more CPUs you have, the higher the -j number may be set to
# here: build using 4 CPU cores
make -j4
</source>

=== Installation ===

Install resulting GRASS GIS binaries into /usr/local/:
<source lang="bash">
sudo make install
</source>

Start GRASS GIS in the terminal:
<source lang="bash">
grass
</source>

'''Done & enjoy!'''

== Hints ==

* Usually, the installation of compiled code is done by using the <source lang="bash" enclose="none">make</source> tool. Alternatively, this can be done by using the ''checkinstall'' tool (i.e., <source lang="bash" enclose="none">sudo checkinstall</source> instead of <source lang="bash" enclose="none">sudo make install</source>) which eases off removal of packages. If ''checkinstall'' fails to deliver, please note some related bugs: [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/78455 78455] and [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/599163 599163]. Useful information on using ''checkinstall'': [https://help.ubuntu.com/community/CompilingEasyHowTo Compiling things on Ubuntu the Easy Way].

* In multi-core processors, the compilation performance can be boosted by using ''-j'' switches (e.g. <source lang="bash" enclose="none">make -j2</source> or <source lang="bash" enclose="none">make -j3</source> or even <source lang="bash" enclose="none">make -j4</source>) which specify the number of jobs (commands) to run simultaneously.

== Pre-compiled packages and backports ==

'''Pre-compiled packages and backports''' are available from [https://wiki.ubuntu.com/UbuntuGIS UbuntuGIS] via their [https://launchpad.net/~ubuntugis/+archive/ppa/ ppa.launchpad stable] and [https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable ppa.launchpad unstable] repositories. '''This is by far the simplest and fastest solution. Please prefer it over the manual way of compiling source code yourself as described below.'''

Version overview:
* jammy2 8.4
* noble 8.3
* jammy (22.04): 8.3
* focal (20.04 LTS): 8.2
* bionic (18.04 LTS): 7.8

a) Daily ready-to-install GRASS GIS builds of the stable release branch and master are available from ''ppa:grass/grass-devel'':

<source lang=bash>
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo add-apt-repository ppa:grass/grass-devel
</source>

b) Latest packaged stable version of GRASS GIS is available from ''ppa:grass/grass-stable'':
<source lang=bash>
sudo add-apt-repository ppa:ubuntugis/ppa

sudo apt-get install grass
</source>

== Dependencies ==

=== Current stable Ubuntu version ===
First, update the system from the repositories<source lang="bash">
sudo apt-get update && sudo apt-get upgrade
</source>

Then, install ''SQLite'', ''git'' and ''dependencies'' for compiling PROJ, GEOS, GDAL/OGR, GRASS, GDAL-GRASS-PLUGIN (some additional packages may be required in this case); the following action will also install various dependencies (listed in the command line as <source lang="bash" enclose="none">The following extra packages will be installed:</source>...):<br/>

<source lang="bash">
# this is a single command, please copy-paste it entirely into the terminal:
sudo apt-get install \
build-essential \
flex make bison gcc libgcc1 g++ cmake ccache \
python python-dev \
python-opengl \
python-wxversion python-wxtools python-wxgtk3.2 \
python-dateutil libgsl-dev python-numpy \

ghostscript
</source>

* See the additional packages bellow and in other sections and install them. Note that some of them are [https://github.com/OSGeo/grass/blob/main/REQUIREMENTS.md required], namely PROJ, GEOS and GDAL. If you don't have special requirements, it is usually enough just to install PROJ, GEOS and GDAL from repository (rather then compile them manually).

* for mysql support, <source lang="bash" enclose="none">libmysqlclient-dev</source> is required
<source lang="bash">
sudo apt-get install libmysqlclient-dev
</source>

* for netcdf support, <source lang="bash" enclose="none">netcdf-bin</source> and <source lang="bash" enclose="none">libnetcdf-dev</source> is required
<source lang="bash">
sudo apt-get install netcdf-bin libnetcdf-dev
</source>

* for {{AddonCmd|i.spec.unmix}} Addon support, install LAPACK and BLAS:
<source lang="bash">
sudo apt-get install libblas-dev liblapack-dev
</source>

* create a directory as a simple user where all source code is going to be stored -- in this example, a directory named <source lang="bash" enclose="none">src</source> under <source lang="bash" enclose="none">/usr/local</source> is created <source lang="bash">
sudo mkdir /usr/local/src
</source>

* take over directories ownerships ('''replace''' below the terms ''userid'' and ''groupid'' with a real <source lang="bash" enclose="none">userid</source>): <source lang="bash">
sudo chown userid:groupid /usr/local/src</source>

* similarly, grant <source lang="bash" enclose="none">rwx</source> (read-write-execute) permissions for our ''userid'' and ''groupid'' onto the <source lang="bash" enclose="none">src</source> directory: <source lang="bash">
sudo chmod ug+rwx /usr/local/src</source>

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL ==

=== PROJ ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
sudo apt-get install libproj-dev proj-data proj-bin
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-proj-share=/usr/local/share/proj/</source> by <source lang="bash" enclose="none">--with-proj-share=/usr/share/proj/</source>

=== GEOS ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
# probably you also need to additionally install "libgeos-c1v5"
sudo apt-get install libgeos-dev
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-geos=/usr/local/bin/geos-config</source> by <source lang="bash" enclose="none">--with-geos=/usr/bin/geos-config</source>

=== GDAL ===

Install the <source lang="bash" enclose="none">dev</source> package (possibly without support for datumgrid):

<source lang="bash">
sudo apt-get install libgdal-dev
</source>

For support of WMS in wxGUI install Python GDAL bindings and GDAL executables:
<source lang="bash">
sudo apt-get install python-gdal gdal-bin
</source>

* Install also the required extra packages (note the message: <source lang="bash" enclose="none">The following extra packages will be installed:</source>)
* Look out for packages to be removed by this operation -- this is most likely caused by incompatible package versions. Fix these problems in advance using commands like the following: <source lang="bash">
sudo apt-get install <package>=<required.version></source>

=== GRASS-GIS ===

[[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]]

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL from GIS.lab PPA==

Ivan Mincik has made all required packages available in his [https://launchpad.net/~imincik/+archive/ubuntu/gis PPA]:

<source lang="bash">
sudo add-apt-repository ppa:imincik/gis
sudo apt-get install libproj-dev libgdal-dev python-gdal libgeos-dev
</source>

Now you can either also install GRASS GIS from there or compile it yourself (see [[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]])

== Compile from source ==

=== PROJ ===

* within the directory <source lang="bash" enclose="none">/usr/local/src</source> (create it if it does not exist) checkout <source lang="bash" enclose="none">proj</source> from its GitHub repository: <source lang="bash">
https://github.com/OSGeo/PROJ/
</source>

* get [http://download.osgeo.org/proj/proj-datumgrid-1.8.zip '''proj-datumgrid-1.8.zip'''] or related files from [https://trac.osgeo.org/proj proj' trac] and move it under <source lang="bash" enclose="none">proj/nad</source>
<ul><source lang="bash">
wget http://download.osgeo.org/proj/proj-datumgrid-1.8.zip
mv proj-datumgrid-1.8.zip /usr/local/src/proj/nad
cd /usr/local/src/proj/nad
</source>
</ul>

* decompress it <source lang="bash">
unzip proj-datumgrid-1.8.zip
</source>

* go back to the <source lang="bash" enclose="none">proj</source> directory <source lang="bash">
cd /usr/local/src/proj
</source>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* ensure that <source lang="bash" enclose="none">/usr/local/lib</source> is added to <source lang="bash" enclose="none">/etc/ld.so.conf</source> and afterwards run <source lang="bash">
sudo ldconfig
</source>

* finally, go back to the parent directory simply by instructing<source lang="bash">
cd ..
</source>

=== GEOS ===

* download '''geos-3.12.2.tar.bz2''' from [https://libgeos.org/ https://libgeos.org/] using <source lang="bash" enclose="none">wget</source> <source lang="bash">
wget https://download.osgeo.org/geos/geos-3.12.2.tar.bz2
</source>

* move to the "source-code" directory and decompress
<ul><source lang="bash">
cd /usr/local/src/
bunzip2 geos-3.12.2.tar.bz2
tar xvf geos-3.12.2.tar
</source>
</ul>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* move to geos directory <source lang="bash">
cd geos-3.12.2
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* do not forget to execute <source lang="bash">
sudo ldconfig
</source>

=== GDAL ===

'''Note''', GDAL must be compiled '''without''' GRASS support!

* download the current stable version (see https://github.com/OSGeo/gdal/releases for latest version):
<source lang="bash">
wget https://github.com/OSGeo/gdal/releases/download/v3.9.1/gdal-3.9.1.tar.gz
</source>

Follow the instructions to compile GDAL:
https://gdal.org/development/building_from_source.html

=== GRASS GIS ===

Note the differences between different GRASS GIS version (branches) in download and cofiguration. Note also the changes required if you installed some of the dependencies from packages (rather then compiled them yourself).

To fully understand the build process, read the <code>INSTALL</code> file, which is located in GRASS' source code root directory.

''' Getting GRASS' source code '''

Select from one of the GRASS GIS versions and download the source code:

https://github.com/OSGeo/grass/releases/

''' Configure, Compile and Install'''

Enter the directory with the source code, for example:

<source lang="bash">
cd grass
</source>

* '''GRASS GIS example configuration''' (which can/should be adjusted according to specific needs):
<ul>
<source lang="bash">
CFLAGS="-O2 -Wall" LDFLAGS="-s" ./configure \
--with-nls \
--with-cxx \
--with-proj-share=/usr/local/share/proj/ \
--with-geos=/usr/local/bin/geos-config \
--with-wxwidgets \
--with-cairo \
--with-opengl-libs=/usr/include/GL \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--with-sqlite=yes \
--with-mysql=yes --with-mysql-includes="/usr/include/mysql" \
--with-odbc=no \
--with-pdal
</source>
</ul>
<ul>
'''Note''', the above configuration uses the <code>PROJ</code> and <code>GEOS</code> packages compiled from the source. In the case that pre-compiled versions from the repository are required, remove the above corresponding lines to use the "defaults", i.e. (note the backslashe at the end of each line)
<source lang="bash">
--with-proj-share=/usr/share/proj \
--with-geos=/usr/bin/geos-config \
</source>
</ul>

* compile & install <source lang="bash">
make -j2 && sudo make install && sudo ldconfig
</source>

<ul> or <source lang="bash">
make -j2 && sudo checkinstall && sudo ldconfig
</source>
</ul>

For subsequent updates execute (not need for the first time):
<source lang="bash">
svn up
make -j2 && sudo make install && sudo ldconfig
</source>

Sometimes, it is required to clean previous configuration and compilation:
<source lang="bash">
make distclean
svn up
./configure ... # (use the configure command above)
make -j2 && sudo make install && sudo ldconfig
</source>

=== GDAL-GRASS-Plugin ===

See: https://github.com/OSGeo/gdal-grass

* get the plugin from [https://github.com/OSGeo/gdal-grass/releases GitHub]: "gdal-grass-X.Y.Z.tar.gz" using <source lang="bash" enclose="none">wget</source>
<ul><source lang="bash">
# update version number accordingly!
wget https://github.com/OSGeo/gdal-grass/archive/refs/tags/1.0.2.tar.gz -O gdal-grass-1.0.2.tar.gz
tar xvzf gdal-grass-1.0.2.tar.gz
cd gdal-grass-1.0.2
</source></ul>

* create <source lang="bash" enclose="none">/etc/ld.so.conf.d/grass.conf</source> or add in <source lang="bash" enclose="none">/etc/ld.so.conf</source> the GRASS library path:
<ul><source lang="bash">
# GRASS GIS stable library path (adapt as needed)
/usr/local/src/releasebranch_8_4/lib

# GRASS GIS development version library path (adapt as needed)
/usr/local/src/grass_master/lib
</source></ul>

* optionally, clean previous configurations/compilations<source lang="bash">
make distclean</source>

* configure -- point to GRASS installation/binaries
<ul><source lang="bash"> ./configure \
--prefix=/usr/local \
--with-gdal=/usr/local/bin/gdal-config \
--with-grass=/usr/local/grass/ \
--with-autoload="/usr/local/lib64/gdalplugins/" \
--with-ld-shared="g++ -shared"</source></ul>
</ul>

* compile & install using checkinstall<source lang="bash">
make -j2 && sudo checkinstall</source>

= Post compilation/installation control =

* For a recommended quick-check read the [https://grass.osgeo.org/wiki/Compile_and_install_GRASS_and_QGIS_with_GDAL/OGR_Plugin#Troubleshooting Troubleshooting] section at [https://grass.osgeo.org/wiki/Compile_and_install_GDAL-GRASS_plugin Compile_and_install_GDAL-GRASS_plugin]

* in case of errors in future compilation attempts, remember to remove program binaries and files created with the "configuration" from previous compilations with
make distclean

* another common mistake is compiling a module against some GRASS version and then try to run it through another GRASS version. The solution is to recompile the affected module or, in case there are multiple GRASS installations, set up properly LD_LIBRARY_PATH paths.

= Removal of GRASS =

To get rid of a GRASS binaries installation, delete (update version numbers accordingly)
* <source lang="bash" enclose="none">/usr/local/grass</source> (directory, binaries location)
* <source lang="bash" enclose="none">/usr/local/bin/grass</source> (file)
* <source lang="bash" enclose="none">/home/username/.grassrc8</source> (file)

If wanted, delete also the complete source code:
* <source lang="bash" enclose="none">/usr/local/src/grass_release</source> (directory, source code location)

To remove <code>grass</code> (or any other package) which was installed by <source lang="bash" enclose="none">checkinstall</source>, use <source lang="bash" enclose="none">dpkg</source>, e.g.<source lang="bash">
sudo dpkg -r grass # package name defined at installation is important</source>

Please, prefer pre-compiled packages over the manual way described below unless you know ''what'' and ''how'', you want to learn and help testing.'''</span>
</div>

== Quick instructions ==

These instructions should work fine on Ubuntu distributions:

=== Install geospatial dependencies ===

1. Install some dependencies (PROJ, GEOS, GDAL libraries) and the compiler tools <br />
(note: you need Python 3)

<source lang="bash">
# be sure to have an updated system
sudo apt update && sudo apt upgrade -y

# install PROJ
sudo apt install libproj-dev proj-data proj-bin unzip -y
</source>

<source lang="bash">
# optionally, install (selected) datum grid files
sudo apt-get install proj-data

# install GEOS
sudo apt install libgeos-dev -y

# install GDAL
sudo apt install libgdal-dev python3-gdal gdal-bin -y

## install PDAL (optional) - apparently unavailable on Ubuntu
#sudo apt install libpdal-dev pdal -y

# Python3 precedence over Python2 (which is end-of-life since 2019, so it should be the default anyway)
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1
</source>

Install compiler stuff and further dependencies.
Note: this is a single command, please copy-paste it entirely into the terminal:

=== Install further compilation dependencies (Ubuntu 24.04) ===

For Ubuntu 24.04, including wxPython packages for GUI support:

<source lang="bash">
# this is a single command, please copy-paste it entirely into the terminal:
sudo apt-get install \
build-essential \
flex make bison gcc libgcc-s1 g++ \
python3 python3-dev \
python3-dateutil libgsl-dev python3-numpy \
zlib1g-dev gettext \
libtiff-dev libpnglite-dev \
sqlite3 libsqlite3-dev \
libboost-thread-dev libboost-program-options-dev \
systemd-resolved \
git \
checkinstall \
cmake ccache \
python3-opengl libwxbase3.2-1t64 libwxgtk3.2-dev \
python3-wxgtk4.0 \
cairo-dock libcairo2-dev \
libpq-dev \
libfreetype-dev \
libfftw3-dev libfftw3-single3 libfftw3-double3 \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev \
libglu1-mesa-dev libxmu-dev \
ghostscript
</source>

For NVIZ on Ubuntu, to also have video support (optional):
<source lang="bash">
sudo apt-get install \
ffmpeg libavutil-dev \
libffmpegthumbnailer-dev \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev -y
</source>

=== Source code download ===
Now we have all "ingredients" readily installed on our system.

'''Source code download''':

There a two ways of getting the source code: either use a) the weekly snapshot (cannot be updated, or b) the source code from the GitHub repository (you can update your local copy easily in future):

'''a) Download of the weekly source code snapshot (not recommended):'''
<source lang="bash">
# download latest GRASS GIS 8.x stable release source code:
mkdir $HOME/src/
cd $HOME/src/
wget https://grass.osgeo.org/grass84/source/snapshot/grass-8.4.git_src_snapshot_latest.tar.gz

# Unpack source code package and remove tarball archive:
tar xvfz grass-8.4.git_src_snapshot_latest.tar.gz
rm -f grass-8.4.git_src_snapshot_latest.tar.gz

# rename source code directory (yes, with the questionmarks!)
mv grass-8.4.git_src_snapshot_20??_??_?? grass-8.4.latest
cd grass-8.4.latest/
</source>

'''b) Download of the current development version from GitHub (adopt the path below accordingly)'''

Note: to find the current version number (8_x), see https://github.com/OSGeo/grass/branches:

<source lang="bash">
sudo apt-get install git
git clone https://github.com/OSGeo/grass.git grass-8.4.latest.git
cd grass-8.4.latest.git/
git checkout releasebranch_8_4
</source>

=== Compilation ===
Now we can '''compile''' the source code in order to generate the GRASS GIS binaries:

<source lang="bash">
# "configure" source code for local machine (checks for CPU type etc):
MYCFLAGS='-O2 -fPIC -fno-common -fexceptions -std=gnu99 -fstack-protector -m64'
#MYCXXFLAGS=''
MYLDFLAGS='-Wl,--no-undefined -Wl,-z,now'

LDFLAGS="$MYLDFLAGS" CFLAGS="$MYCFLAGS" CXXFLAGS="$MYCXXFLAGS" ./configure \
--with-cxx \
--enable-largefile \
--with-proj --with-proj-share=/usr/share/proj \
--with-gdal=/usr/bin/gdal-config \
--with-python \
--with-geos \
--with-sqlite \
--with-nls \
--with-zstd \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-wxwidgets \
--with-fftw \
--with-openmp \
--with-opengl-libs=/usr/include/GL \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--without-pdal \
--without-netcdf \
--without-mysql \
--without-odbc \
--without-ffmpeg
</source>

Now compile the source code (this will take some time as it generates binary code from the source code):
<source lang="bash">
# note: the more CPUs you have, the higher the -j number may be set to
# here: build using 4 CPU cores
make -j4
</source>

=== Installation ===

Install resulting GRASS GIS binaries into /usr/local/:
<source lang="bash">
sudo make install
</source>

Start GRASS GIS in the terminal:
<source lang="bash">
grass
</source>

'''Done & enjoy!'''

== Hints ==

* Usually, the installation of compiled code is done by using the <source lang="bash" enclose="none">make</source> tool. Alternatively, this can be done by using the ''checkinstall'' tool (i.e., <source lang="bash" enclose="none">sudo checkinstall</source> instead of <source lang="bash" enclose="none">sudo make install</source>) which eases off removal of packages. If ''checkinstall'' fails to deliver, please note some related bugs: [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/78455 78455] and [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/599163 599163]. Useful information on using ''checkinstall'': [https://help.ubuntu.com/community/CompilingEasyHowTo Compiling things on Ubuntu the Easy Way].

* In multi-core processors, the compilation performance can be boosted by using ''-j'' switches (e.g. <source lang="bash" enclose="none">make -j2</source> or <source lang="bash" enclose="none">make -j3</source> or even <source lang="bash" enclose="none">make -j4</source>) which specify the number of jobs (commands) to run simultaneously.

== Pre-compiled packages and backports ==

'''Pre-compiled packages and backports''' are available from [https://wiki.ubuntu.com/UbuntuGIS UbuntuGIS] via their [https://launchpad.net/~ubuntugis/+archive/ppa/ ppa.launchpad stable] and [https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable ppa.launchpad unstable] repositories. '''This is by far the simplest and fastest solution. Please prefer it over the manual way of compiling source code yourself as described below.'''

* See the additional packages bellow and in other sections and install them. Note that some of them are [https://github.com/OSGeo/grass/blob/main/REQUIREMENTS.md required], namely PROJ, GEOS and GDAL. If you don't have special requirements, it is usually enough just to install PROJ, GEOS and GDAL from repository (rather then compile them manually).

* for mysql support, <source lang="bash" enclose="none">libmysqlclient-dev</source> is required
<source lang="bash">
sudo apt-get install libmysqlclient-dev
</source>

* for netcdf support, <source lang="bash" enclose="none">netcdf-bin</source> and <source lang="bash" enclose="none">libnetcdf-dev</source> is required
<source lang="bash">
sudo apt-get install netcdf-bin libnetcdf-dev
</source>

* for {{AddonCmd|i.spec.unmix}} Addon support, install LAPACK and BLAS:
<source lang="bash">
sudo apt-get install libblas-dev liblapack-dev
</source>

* create a directory as a simple user where all source code is going to be stored -- in this example, a directory named <source lang="bash" enclose="none">src</source> under <source lang="bash" enclose="none">/usr/local</source> is created <source lang="bash">
sudo mkdir /usr/local/src
</source>

* take over directories ownerships ('''replace''' below the terms ''userid'' and ''groupid'' with a real <source lang="bash" enclose="none">userid</source>): <source lang="bash">
sudo chown userid:groupid /usr/local/src</source>

* similarly, grant <source lang="bash" enclose="none">rwx</source> (read-write-execute) permissions for our ''userid'' and ''groupid'' onto the <source lang="bash" enclose="none">src</source> directory: <source lang="bash">
sudo chmod ug+rwx /usr/local/src</source>

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL ==

=== PROJ ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
sudo apt-get install libproj-dev proj-data proj-bin
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-proj-share=/usr/local/share/proj/</source> by <source lang="bash" enclose="none">--with-proj-share=/usr/share/proj/</source>

=== GEOS ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
# probably you also need to additionally install "libgeos-c1v5"
sudo apt-get install libgeos-dev
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-geos=/usr/local/bin/geos-config</source> by <source lang="bash" enclose="none">--with-geos=/usr/bin/geos-config</source>

=== GDAL ===

Install the <source lang="bash" enclose="none">dev</source> package (possibly without support for datumgrid):

<source lang="bash">
sudo apt-get install libgdal-dev
</source>

For support of WMS in wxGUI install Python GDAL bindings and GDAL executables:
<source lang="bash">
sudo apt-get install python-gdal gdal-bin
</source>

* Install also the required extra packages (note the message: <source lang="bash" enclose="none">The following extra packages will be installed:</source>)
* Look out for packages to be removed by this operation -- this is most likely caused by incompatible package versions. Fix these problems in advance using commands like the following: <source lang="bash">
sudo apt-get install <package>=<required.version></source>

=== GRASS-GIS ===

[[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]]

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL from GIS.lab PPA==

Ivan Mincik has made all required packages available in his [https://launchpad.net/~imincik/+archive/ubuntu/gis PPA]:

<source lang="bash">
sudo add-apt-repository ppa:imincik/gis
sudo apt-get install libproj-dev libgdal-dev python-gdal libgeos-dev
</source>

Now you can either also install GRASS GIS from there or compile it yourself (see [[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]])

== Compile from source ==

=== PROJ ===

* within the directory <source lang="bash" enclose="none">/usr/local/src</source> (create it if it does not exist) checkout <source lang="bash" enclose="none">proj</source> from its GitHub repository: <source lang="bash">
https://github.com/OSGeo/PROJ/
</source>

* get [http://download.osgeo.org/proj/proj-datumgrid-1.8.zip '''proj-datumgrid-1.8.zip'''] or related files from [https://trac.osgeo.org/proj proj' trac] and move it under <source lang="bash" enclose="none">proj/nad</source>
<ul><source lang="bash">
wget http://download.osgeo.org/proj/proj-datumgrid-1.8.zip
mv proj-datumgrid-1.8.zip /usr/local/src/proj/nad
cd /usr/local/src/proj/nad
</source>
</ul>

* decompress it <source lang="bash">
unzip proj-datumgrid-1.8.zip
</source>

* go back to the <source lang="bash" enclose="none">proj</source> directory <source lang="bash">
cd /usr/local/src/proj
</source>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* ensure that <source lang="bash" enclose="none">/usr/local/lib</source> is added to <source lang="bash" enclose="none">/etc/ld.so.conf</source> and afterwards run <source lang="bash">
sudo ldconfig
</source>

* finally, go back to the parent directory simply by instructing<source lang="bash">
cd ..
</source>

=== GEOS ===

* download '''geos-3.12.2.tar.bz2''' from [https://libgeos.org/ https://libgeos.org/] using <source lang="bash" enclose="none">wget</source> <source lang="bash">
wget https://download.osgeo.org/geos/geos-3.12.2.tar.bz2
</source>

* move to the "source-code" directory and decompress
<ul><source lang="bash">
cd /usr/local/src/
bunzip2 geos-3.12.2.tar.bz2
tar xvf geos-3.12.2.tar
</source>
</ul>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* move to geos directory <source lang="bash">
cd geos-3.12.2
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* do not forget to execute <source lang="bash">
sudo ldconfig
</source>

=== GDAL ===

'''Note''', GDAL must be compiled '''without''' GRASS support!

* download the current stable version (see https://github.com/OSGeo/gdal/releases for latest version):
<source lang="bash">
wget https://github.com/OSGeo/gdal/releases/download/v3.9.1/gdal-3.9.1.tar.gz
</source>

Follow the instructions to compile GDAL:
https://gdal.org/development/building_from_source.html

=== GRASS GIS ===

Note the differences between different GRASS GIS version (branches) in download and cofiguration. Note also the changes required if you installed some of the dependencies from packages (rather then compiled them yourself).

To fully understand the build process, read the <code>INSTALL</code> file, which is located in GRASS' source code root directory.

''' Getting GRASS' source code '''

Select from one of the GRASS GIS versions and download the source code:

https://github.com/OSGeo/grass/releases/

''' Configure, Compile and Install'''

Enter the directory with the source code, for example:

<source lang="bash">
cd grass
</source>

* '''GRASS GIS example configuration''' (which can/should be adjusted according to specific needs):
<ul>
<source lang="bash">
CFLAGS="-O2 -Wall" LDFLAGS="-s" ./configure \
--with-nls \
--with-cxx \
--with-proj-share=/usr/local/share/proj/ \
--with-geos=/usr/local/bin/geos-config \
--with-wxwidgets \
--with-cairo \
--with-opengl-libs=/usr/include/GL \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--with-sqlite=yes \
--with-mysql=yes --with-mysql-includes="/usr/include/mysql" \
--with-odbc=no \
--with-pdal
</source>
</ul>
<ul>
'''Note''', the above configuration uses the <code>PROJ</code> and <code>GEOS</code> packages compiled from the source. In the case that pre-compiled versions from the repository are required, remove the above corresponding lines to use the "defaults", i.e. (note the backslashe at the end of each line)
<source lang="bash">
--with-proj-share=/usr/share/proj \
--with-geos=/usr/bin/geos-config \
</source>
</ul>

* compile & install <source lang="bash">
make -j2 && sudo make install && sudo ldconfig
</source>

<ul> or <source lang="bash">
make -j2 && sudo checkinstall && sudo ldconfig
</source>
</ul>

For subsequent updates execute (not need for the first time):
<source lang="bash">
svn up
make -j2 && sudo make install && sudo ldconfig
</source>

Sometimes, it is required to clean previous configuration and compilation:
<source lang="bash">
make distclean
svn up
./configure ... # (use the configure command above)
make -j2 && sudo make install && sudo ldconfig
</source>

=== GDAL-GRASS-Plugin ===

See: https://github.com/OSGeo/gdal-grass

* get the plugin from [https://github.com/OSGeo/gdal-grass/releases GitHub]: "gdal-grass-X.Y.Z.tar.gz" using <source lang="bash" enclose="none">wget</source>
<ul><source lang="bash">
# update version number accordingly!
wget https://github.com/OSGeo/gdal-grass/archive/refs/tags/1.0.2.tar.gz -O gdal-grass-1.0.2.tar.gz
tar xvzf gdal-grass-1.0.2.tar.gz
cd gdal-grass-1.0.2
</source></ul>

* create <source lang="bash" enclose="none">/etc/ld.so.conf.d/grass.conf</source> or add in <source lang="bash" enclose="none">/etc/ld.so.conf</source> the GRASS library path:
<ul><source lang="bash">
# GRASS GIS stable library path (adapt as needed)
/usr/local/src/releasebranch_8_4/lib

# GRASS GIS development version library path (adapt as needed)
/usr/local/src/grass_master/lib
</source></ul>

* optionally, clean previous configurations/compilations<source lang="bash">
make distclean</source>

* configure -- point to GRASS installation/binaries
<ul><source lang="bash"> ./configure \
--prefix=/usr/local \
--with-gdal=/usr/local/bin/gdal-config \
--with-grass=/usr/local/grass/ \
--with-autoload="/usr/local/lib64/gdalplugins/" \
--with-ld-shared="g++ -shared"</source></ul>
</ul>

* compile & install using checkinstall<source lang="bash">
make -j2 && sudo checkinstall</source>

= Post compilation/installation control =

* For a recommended quick-check read the [https://grass.osgeo.org/wiki/Compile_and_install_GRASS_and_QGIS_with_GDAL/OGR_Plugin#Troubleshooting Troubleshooting] section at [https://grass.osgeo.org/wiki/Compile_and_install_GDAL-GRASS_plugin Compile_and_install_GDAL-GRASS_plugin]

* in case of errors in future compilation attempts, remember to remove program binaries and files created with the "configuration" from previous compilations with
make distclean

* another common mistake is compiling a module against some GRASS version and then try to run it through another GRASS version. The solution is to recompile the affected module or, in case there are multiple GRASS installations, set up properly LD_LIBRARY_PATH paths.

= Removal of GRASS =

To get rid of a GRASS binaries installation, delete (update version numbers accordingly)
* <source lang="bash" enclose="none">/usr/local/grass</source> (directory, binaries location)
* <source lang="bash" enclose="none">/usr/local/bin/grass</source> (file)
* <source lang="bash" enclose="none">/home/username/.grassrc8</source> (file)

If wanted, delete also the complete source code:
* <source lang="bash" enclose="none">/usr/local/src/grass_release</source> (directory, source code location)

To remove <code>grass</code> (or any other package) which was installed by <source lang="bash" enclose="none">checkinstall</source>, use <source lang="bash" enclose="none">dpkg</source>, e.g.<source lang="bash">
sudo dpkg -r grass # package name defined at installation is important</source>

Please, prefer pre-compiled packages over the manual way described below unless you know ''what'' and ''how'', you want to learn and help testing.'''</span>
</div>

== Quick instructions ==

These instructions should work fine on Ubuntu distributions:

=== Install geospatial dependencies ===

1. Install some dependencies (PROJ, GEOS, GDAL libraries) and the compiler tools <br />
(note: you need Python 3)

<source lang="bash">
# be sure to have an updated system
sudo apt update && sudo apt upgrade -y

# install PROJ
sudo apt install libproj-dev proj-data proj-bin unzip -y
</source>

<source lang="bash">
# optionally, install (selected) datum grid files
sudo apt-get install proj-data

# install GEOS
sudo apt install libgeos-dev -y

# install GDAL
sudo apt install libgdal-dev python3-gdal gdal-bin -y

## install PDAL (optional) - apparently unavailable on Ubuntu
#sudo apt install libpdal-dev pdal -y

# Python3 precedence over Python2 (which is end-of-life since 2019, so it should be the default anyway)
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1
</source>

Install compiler stuff and further dependencies.
Note: this is a single command, please copy-paste it entirely into the terminal:

=== Install further compilation dependencies (Ubuntu 24.04) ===

For Ubuntu 24.04, including wxPython packages for GUI support:

<source lang="bash">
# this is a single command, please copy-paste it entirely into the terminal:
sudo apt-get install \
build-essential \
flex make bison gcc libgcc-s1 g++ \
python3 python3-dev \
python3-dateutil libgsl-dev python3-numpy \
zlib1g-dev gettext \
libtiff-dev libpnglite-dev \
sqlite3 libsqlite3-dev \
libboost-thread-dev libboost-program-options-dev \
systemd-resolved \
git \
checkinstall \
cmake ccache \
python3-opengl libwxbase3.2-1t64 libwxgtk3.2-dev \
python3-wxgtk4.0 \
cairo-dock libcairo2-dev \
libpq-dev \
libfreetype-dev \
libfftw3-dev libfftw3-single3 libfftw3-double3 \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev \
libglu1-mesa-dev libxmu-dev \
ghostscript
</source>

For NVIZ on Ubuntu, to also have video support (optional):
<source lang="bash">
sudo apt-get install \
ffmpeg libavutil-dev \
libffmpegthumbnailer-dev \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev -y
</source>

=== Source code download ===
Now we have all "ingredients" readily installed on our system.

'''Source code download''':

There a two ways of getting the source code: either use a) the weekly snapshot (cannot be updated, or b) the source code from the GitHub repository (you can update your local copy easily in future):

'''a) Download of the weekly source code snapshot (not recommended):'''
<source lang="bash">
# download latest GRASS GIS 8.x stable release source code:
mkdir $HOME/src/
cd $HOME/src/
wget https://grass.osgeo.org/grass84/source/snapshot/grass-8.4.git_src_snapshot_latest.tar.gz

# Unpack source code package and remove tarball archive:
tar xvfz grass-8.4.git_src_snapshot_latest.tar.gz
rm -f grass-8.4.git_src_snapshot_latest.tar.gz

# rename source code directory (yes, with the questionmarks!)
mv grass-8.4.git_src_snapshot_20??_??_?? grass-8.4.latest
cd grass-8.4.latest/
</source>

'''b) Download of the current development version from GitHub (adopt the path below accordingly)'''

Note: to find the current version number (8_x), see https://github.com/OSGeo/grass/branches:

<source lang="bash">
sudo apt-get install git
git clone https://github.com/OSGeo/grass.git grass-8.4.latest.git
cd grass-8.4.latest.git/
git checkout releasebranch_8_4
</source>

=== Compilation ===
Now we can '''compile''' the source code in order to generate the GRASS GIS binaries:

<source lang="bash">
# "configure" source code for local machine (checks for CPU type etc):
MYCFLAGS='-O2 -fPIC -fno-common -fexceptions -std=gnu99 -fstack-protector -m64'
#MYCXXFLAGS=''
MYLDFLAGS='-Wl,--no-undefined -Wl,-z,now'

LDFLAGS="$MYLDFLAGS" CFLAGS="$MYCFLAGS" CXXFLAGS="$MYCXXFLAGS" ./configure \
--with-cxx \
--enable-largefile \
--with-proj --with-proj-share=/usr/share/proj \
--with-gdal=/usr/bin/gdal-config \
--with-python \
--with-geos \
--with-sqlite \
--with-nls \
--with-zstd \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-wxwidgets \
--with-fftw \
--with-openmp \
--with-opengl-libs=/usr/include/GL \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--without-pdal \
--without-netcdf \
--without-mysql \
--without-odbc \
--without-ffmpeg
</source>

Now compile the source code (this will take some time as it generates binary code from the source code):
<source lang="bash">
# note: the more CPUs you have, the higher the -j number may be set to
# here: build using 4 CPU cores
make -j4
</source>

=== Installation ===

Install resulting GRASS GIS binaries into /usr/local/:
<source lang="bash">
sudo make install
</source>

Start GRASS GIS in the terminal:
<source lang="bash">
grass
</source>

'''Done & enjoy!'''

== Hints ==

* Usually, the installation of compiled code is done by using the <source lang="bash" enclose="none">make</source> tool. Alternatively, this can be done by using the ''checkinstall'' tool (i.e., <source lang="bash" enclose="none">sudo checkinstall</source> instead of <source lang="bash" enclose="none">sudo make install</source>) which eases off removal of packages. If ''checkinstall'' fails to deliver, please note some related bugs: [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/78455 78455] and [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/599163 599163]. Useful information on using ''checkinstall'': [https://help.ubuntu.com/community/CompilingEasyHowTo Compiling things on Ubuntu the Easy Way].

* In multi-core processors, the compilation performance can be boosted by using ''-j'' switches (e.g. <source lang="bash" enclose="none">make -j2</source> or <source lang="bash" enclose="none">make -j3</source> or even <source lang="bash" enclose="none">make -j4</source>) which specify the number of jobs (commands) to run simultaneously.

== Pre-compiled packages and backports ==

'''Pre-compiled packages and backports''' are available from [https://wiki.ubuntu.com/UbuntuGIS UbuntuGIS] via their [https://launchpad.net/~ubuntugis/+archive/ppa/ ppa.launchpad stable] and [https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable ppa.launchpad unstable] repositories. '''This is by far the simplest and fastest solution. Please prefer it over the manual way of compiling source code yourself as described below.'''

* See the additional packages bellow and in other sections and install them. Note that some of them are [https://github.com/OSGeo/grass/blob/main/REQUIREMENTS.md required], namely PROJ, GEOS and GDAL. If you don't have special requirements, it is usually enough just to install PROJ, GEOS and GDAL from repository (rather then compile them manually).

* for mysql support, <source lang="bash" enclose="none">libmysqlclient-dev</source> is required
<source lang="bash">
sudo apt-get install libmysqlclient-dev
</source>

* for netcdf support, <source lang="bash" enclose="none">netcdf-bin</source> and <source lang="bash" enclose="none">libnetcdf-dev</source> is required
<source lang="bash">
sudo apt-get install netcdf-bin libnetcdf-dev
</source>

* for {{AddonCmd|i.spec.unmix}} Addon support, install LAPACK and BLAS:
<source lang="bash">
sudo apt-get install libblas-dev liblapack-dev
</source>

* create a directory as a simple user where all source code is going to be stored -- in this example, a directory named <source lang="bash" enclose="none">src</source> under <source lang="bash" enclose="none">/usr/local</source> is created <source lang="bash">
sudo mkdir /usr/local/src
</source>

* take over directories ownerships ('''replace''' below the terms ''userid'' and ''groupid'' with a real <source lang="bash" enclose="none">userid</source>): <source lang="bash">
sudo chown userid:groupid /usr/local/src</source>

* similarly, grant <source lang="bash" enclose="none">rwx</source> (read-write-execute) permissions for our ''userid'' and ''groupid'' onto the <source lang="bash" enclose="none">src</source> directory: <source lang="bash">
sudo chmod ug+rwx /usr/local/src</source>

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL ==

=== PROJ ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
sudo apt-get install libproj-dev proj-data proj-bin
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-proj-share=/usr/local/share/proj/</source> by <source lang="bash" enclose="none">--with-proj-share=/usr/share/proj/</source>

=== GEOS ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
# probably you also need to additionally install "libgeos-c1v5"
sudo apt-get install libgeos-dev
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-geos=/usr/local/bin/geos-config</source> by <source lang="bash" enclose="none">--with-geos=/usr/bin/geos-config</source>

=== GDAL ===

Install the <source lang="bash" enclose="none">dev</source> package (possibly without support for datumgrid):

<source lang="bash">
sudo apt-get install libgdal-dev
</source>

For support of WMS in wxGUI install Python GDAL bindings and GDAL executables:
<source lang="bash">
sudo apt-get install python-gdal gdal-bin
</source>

* Install also the required extra packages (note the message: <source lang="bash" enclose="none">The following extra packages will be installed:</source>)
* Look out for packages to be removed by this operation -- this is most likely caused by incompatible package versions. Fix these problems in advance using commands like the following: <source lang="bash">
sudo apt-get install <package>=<required.version></source>

=== GRASS-GIS ===

[[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]]

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL from GIS.lab PPA==

Ivan Mincik has made all required packages available in his [https://launchpad.net/~imincik/+archive/ubuntu/gis PPA]:

<source lang="bash">
sudo add-apt-repository ppa:imincik/gis
sudo apt-get install libproj-dev libgdal-dev python-gdal libgeos-dev
</source>

Now you can either also install GRASS GIS from there or compile it yourself (see [[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]])

== Compile from source ==

=== PROJ ===

* within the directory <source lang="bash" enclose="none">/usr/local/src</source> (create it if it does not exist) checkout <source lang="bash" enclose="none">proj</source> from its GitHub repository: <source lang="bash">
https://github.com/OSGeo/PROJ/
</source>

* get [http://download.osgeo.org/proj/proj-datumgrid-1.8.zip '''proj-datumgrid-1.8.zip'''] or related files from [https://trac.osgeo.org/proj proj' trac] and move it under <source lang="bash" enclose="none">proj/nad</source>
<ul><source lang="bash">
wget http://download.osgeo.org/proj/proj-datumgrid-1.8.zip
mv proj-datumgrid-1.8.zip /usr/local/src/proj/nad
cd /usr/local/src/proj/nad
</source>
</ul>

* decompress it <source lang="bash">
unzip proj-datumgrid-1.8.zip
</source>

* go back to the <source lang="bash" enclose="none">proj</source> directory <source lang="bash">
cd /usr/local/src/proj
</source>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* ensure that <source lang="bash" enclose="none">/usr/local/lib</source> is added to <source lang="bash" enclose="none">/etc/ld.so.conf</source> and afterwards run <source lang="bash">
sudo ldconfig
</source>

* finally, go back to the parent directory simply by instructing<source lang="bash">
cd ..
</source>

=== GEOS ===

* download '''geos-3.12.2.tar.bz2''' from [https://libgeos.org/ https://libgeos.org/] using <source lang="bash" enclose="none">wget</source> <source lang="bash">
wget https://download.osgeo.org/geos/geos-3.12.2.tar.bz2
</source>

* move to the "source-code" directory and decompress
<ul><source lang="bash">
cd /usr/local/src/
bunzip2 geos-3.12.2.tar.bz2
tar xvf geos-3.12.2.tar
</source>
</ul>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* move to geos directory <source lang="bash">
cd geos-3.12.2
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* do not forget to execute <source lang="bash">
sudo ldconfig
</source>

=== GDAL ===

'''Note''', GDAL must be compiled '''without''' GRASS support!

* download the current stable version (see https://github.com/OSGeo/gdal/releases for latest version):
<source lang="bash">
wget https://github.com/OSGeo/gdal/releases/download/v3.9.1/gdal-3.9.1.tar.gz
</source>

Follow the instructions to compile GDAL:
https://gdal.org/development/building_from_source.html

=== GRASS GIS ===

Note the differences between different GRASS GIS version (branches) in download and cofiguration. Note also the changes required if you installed some of the dependencies from packages (rather then compiled them yourself).

To fully understand the build process, read the <code>INSTALL</code> file, which is located in GRASS' source code root directory.

''' Getting GRASS' source code '''

Select from one of the GRASS GIS versions and download the source code:

https://github.com/OSGeo/grass/releases/

''' Configure, Compile and Install'''

Enter the directory with the source code, for example:

<source lang="bash">
cd grass
</source>

* '''GRASS GIS example configuration''' (which can/should be adjusted according to specific needs):
<ul>
<source lang="bash">
CFLAGS="-O2 -Wall" LDFLAGS="-s" ./configure \
--with-nls \
--with-cxx \
--with-proj-share=/usr/local/share/proj/ \
--with-geos=/usr/local/bin/geos-config \
--with-wxwidgets \
--with-cairo \
--with-opengl-libs=/usr/include/GL \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--with-sqlite=yes \
--with-mysql=yes --with-mysql-includes="/usr/include/mysql" \
--with-odbc=no \
--with-pdal
</source>
</ul>
<ul>
'''Note''', the above configuration uses the <code>PROJ</code> and <code>GEOS</code> packages compiled from the source. In the case that pre-compiled versions from the repository are required, remove the above corresponding lines to use the "defaults", i.e. (note the backslashe at the end of each line)
<source lang="bash">
--with-proj-share=/usr/share/proj \
--with-geos=/usr/bin/geos-config \
</source>
</ul>

* compile & install <source lang="bash">
make -j2 && sudo make install && sudo ldconfig
</source>

<ul> or <source lang="bash">
make -j2 && sudo checkinstall && sudo ldconfig
</source>
</ul>

For subsequent updates execute (not need for the first time):
<source lang="bash">
svn up
make -j2 && sudo make install && sudo ldconfig
</source>

Sometimes, it is required to clean previous configuration and compilation:
<source lang="bash">
make distclean
svn up
./configure ... # (use the configure command above)
make -j2 && sudo make install && sudo ldconfig
</source>

=== GDAL-GRASS-Plugin ===

See: https://github.com/OSGeo/gdal-grass

* get the plugin from [https://github.com/OSGeo/gdal-grass/releases GitHub]: "gdal-grass-X.Y.Z.tar.gz" using <source lang="bash" enclose="none">wget</source>
<ul><source lang="bash">
# update version number accordingly!
wget https://github.com/OSGeo/gdal-grass/archive/refs/tags/1.0.2.tar.gz -O gdal-grass-1.0.2.tar.gz
tar xvzf gdal-grass-1.0.2.tar.gz
cd gdal-grass-1.0.2
</source></ul>

* create <source lang="bash" enclose="none">/etc/ld.so.conf.d/grass.conf</source> or add in <source lang="bash" enclose="none">/etc/ld.so.conf</source> the GRASS library path:
<ul><source lang="bash">
# GRASS GIS stable library path (adapt as needed)
/usr/local/src/releasebranch_8_4/lib

# GRASS GIS development version library path (adapt as needed)
/usr/local/src/grass_master/lib
</source></ul>

* optionally, clean previous configurations/compilations<source lang="bash">
make distclean</source>

* configure -- point to GRASS installation/binaries
<ul><source lang="bash"> ./configure \
--prefix=/usr/local \
--with-gdal=/usr/local/bin/gdal-config \
--with-grass=/usr/local/grass/ \
--with-autoload="/usr/local/lib64/gdalplugins/" \
--with-ld-shared="g++ -shared"</source></ul>
</ul>

* compile & install using checkinstall<source lang="bash">
make -j2 && sudo checkinstall</source>

= Post compilation/installation control =

* For a recommended quick-check read the [https://grass.osgeo.org/wiki/Compile_and_install_GRASS_and_QGIS_with_GDAL/OGR_Plugin#Troubleshooting Troubleshooting] section at [https://grass.osgeo.org/wiki/Compile_and_install_GDAL-GRASS_plugin Compile_and_install_GDAL-GRASS_plugin]

* in case of errors in future compilation attempts, remember to remove program binaries and files created with the "configuration" from previous compilations with
make distclean

* another common mistake is compiling a module against some GRASS version and then try to run it through another GRASS version. The solution is to recompile the affected module or, in case there are multiple GRASS installations, set up properly LD_LIBRARY_PATH paths.

= Removal of GRASS =

To get rid of a GRASS binaries installation, delete (update version numbers accordingly)
* <source lang="bash" enclose="none">/usr/local/grass</source> (directory, binaries location)
* <source lang="bash" enclose="none">/usr/local/bin/grass</source> (file)
* <source lang="bash" enclose="none">/home/username/.grassrc8</source> (file)

If wanted, delete also the complete source code:
* <source lang="bash" enclose="none">/usr/local/src/grass_release</source> (directory, source code location)

To remove <code>grass</code> (or any other package) which was installed by <source lang="bash" enclose="none">checkinstall</source>, use <source lang="bash" enclose="none">dpkg</source>, e.g.<source lang="bash">
sudo dpkg -r grass # package name defined at installation is important</source>

Neteler: Update geospatial dependencies

<div class="boilerplate metadata" id="attention" style="-moz-border-radius:30px; border: 1px double #35824B; margin-bottom: 1.5em; padding: 1em; background-color: #f9f9f9;">
<p style="font-size: 150%; text-align: left;"><span style="color:#35824B">'''Attention'''</span> </p><span style="color:#333333">'''The following instructions describe the compilation and installation of GRASS GIS and its required dependencies completely from the source on Ubuntu based systems. Please, prefer pre-compiled packages over the manual way described below unless you know ''what'' and ''how'', you want to learn and help testing.'''</span>
</div>

== Quick instructions ==

These instructions should work fine on Ubuntu distributions:

=== Install geospatial dependencies ===

1. Install some dependencies (PROJ, GEOS, GDAL libraries) and the compiler tools <br />
(note: you need Python 3)

<source lang="bash">
# be sure to have an updated system
sudo apt update && sudo apt upgrade -y

# install PROJ
sudo apt install libproj-dev proj-data proj-bin unzip -y
</source>

<source lang="bash">
# optionally, install (selected) datum grid files
sudo apt-get install proj-data

# install GEOS
sudo apt install libgeos-dev -y

# install GDAL
sudo apt install libgdal-dev python3-gdal gdal-bin -y

## install PDAL (optional) - apparently unavailable on Ubuntu
#sudo apt install libpdal-dev pdal -y

# Python3 precedence over Python2 (which is end-of-life since 2019, so it should be the default anyway)
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1
</source>

Install compiler stuff and further dependencies.
Note: this is a single command, please copy-paste it entirely into the terminal:

=== Install further compilation dependencies (Ubuntu 24.04) ===

For Ubuntu 24.04, including wxPython packages for GUI support:

<source lang="bash">
# this is a single command, please copy-paste it entirely into the terminal:
sudo apt-get install \
build-essential \
flex make bison gcc libgcc-s1 g++ \
python3 python3-dev \
python3-dateutil libgsl-dev python3-numpy \
zlib1g-dev gettext \
libtiff-dev libpnglite-dev \
sqlite3 libsqlite3-dev \
libboost-thread-dev libboost-program-options-dev \
systemd-resolved \
git \
checkinstall \
cmake ccache \
python3-opengl libwxbase3.2-1t64 libwxgtk3.2-dev \
python3-wxgtk4.0 \
cairo-dock libcairo2-dev \
libpq-dev \
libfreetype-dev \
libfftw3-dev libfftw3-single3 libfftw3-double3 \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev \
libglu1-mesa-dev libxmu-dev \
ghostscript
</source>

For NVIZ on Ubuntu, to also have video support (optional):
<source lang="bash">
sudo apt-get install \
ffmpeg libavutil-dev \
libffmpegthumbnailer-dev \
libavcodec-dev \
libxmu-dev \
libavformat-dev libswscale-dev -y
</source>

=== Source code download ===
Now we have all "ingredients" readily installed on our system.

'''Source code download''':

There a two ways of getting the source code: either use a) the weekly snapshot (cannot be updated, or b) the source code from the GitHub repository (you can update your local copy easily in future):

'''a) Download of the weekly source code snapshot (not recommended):'''
<source lang="bash">
# download latest GRASS GIS 8.x stable release source code:
mkdir $HOME/src/
cd $HOME/src/
wget https://grass.osgeo.org/grass84/source/snapshot/grass-8.4.git_src_snapshot_latest.tar.gz

# Unpack source code package and remove tarball archive:
tar xvfz grass-8.4.git_src_snapshot_latest.tar.gz
rm -f grass-8.4.git_src_snapshot_latest.tar.gz

# rename source code directory (yes, with the questionmarks!)
mv grass-8.4.git_src_snapshot_20??_??_?? grass-8.4.latest
cd grass-8.4.latest/
</source>

'''b) Download of the current development version from GitHub (adopt the path below accordingly)'''

Note: to find the current version number (8_x), see https://github.com/OSGeo/grass/branches:

<source lang="bash">
sudo apt-get install git
git clone https://github.com/OSGeo/grass.git grass-8.4.latest.git
cd grass-8.4.latest.git/
git checkout releasebranch_8_4
</source>

=== Compilation ===
Now we can '''compile''' the source code in order to generate the GRASS GIS binaries:

<source lang="bash">
# "configure" source code for local machine (checks for CPU type etc):
MYCFLAGS='-O2 -fPIC -fno-common -fexceptions -std=gnu99 -fstack-protector -m64'
#MYCXXFLAGS=''
MYLDFLAGS='-Wl,--no-undefined -Wl,-z,now'

LDFLAGS="$MYLDFLAGS" CFLAGS="$MYCFLAGS" CXXFLAGS="$MYCXXFLAGS" ./configure \
--with-cxx \
--enable-largefile \
--with-proj --with-proj-share=/usr/share/proj \
--with-gdal=/usr/bin/gdal-config \
--with-python \
--with-geos \
--with-sqlite \
--with-nls \
--with-zstd \
--with-pdal \
--with-cairo --with-cairo-ldflags=-lfontconfig \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-wxwidgets \
--with-fftw \
--with-openmp \
--with-opengl-libs=/usr/include/GL \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--without-netcdf \
--without-mysql \
--without-odbc \
--without-ffmpeg
</source>

Now compile the source code (this will take some time as it generates binary code from the source code):
<source lang="bash">
# note: the more CPUs you have, the higher the -j number may be set to
# here: build using 4 CPU cores
make -j4
</source>

=== Installation ===

Install resulting GRASS GIS binaries into /usr/local/:
<source lang="bash">
sudo make install
</source>

Start GRASS GIS in the terminal:
<source lang="bash">
grass
</source>

'''Done & enjoy!'''

== Hints ==

* Usually, the installation of compiled code is done by using the <source lang="bash" enclose="none">make</source> tool. Alternatively, this can be done by using the ''checkinstall'' tool (i.e., <source lang="bash" enclose="none">sudo checkinstall</source> instead of <source lang="bash" enclose="none">sudo make install</source>) which eases off removal of packages. If ''checkinstall'' fails to deliver, please note some related bugs: [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/78455 78455] and [https://bugs.launchpad.net/ubuntu/+source/checkinstall/+bug/599163 599163]. Useful information on using ''checkinstall'': [https://help.ubuntu.com/community/CompilingEasyHowTo Compiling things on Ubuntu the Easy Way].

* In multi-core processors, the compilation performance can be boosted by using ''-j'' switches (e.g. <source lang="bash" enclose="none">make -j2</source> or <source lang="bash" enclose="none">make -j3</source> or even <source lang="bash" enclose="none">make -j4</source>) which specify the number of jobs (commands) to run simultaneously.

== Pre-compiled packages and backports ==

'''Pre-compiled packages and backports''' are available from [https://wiki.ubuntu.com/UbuntuGIS UbuntuGIS] via their [https://launchpad.net/~ubuntugis/+archive/ppa/ ppa.launchpad stable] and [https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable ppa.launchpad unstable] repositories. '''This is by far the simplest and fastest solution. Please prefer it over the manual way of compiling source code yourself as described below.'''

* See the additional packages bellow and in other sections and install them. Note that some of them are [https://github.com/OSGeo/grass/blob/main/REQUIREMENTS.md required], namely PROJ, GEOS and GDAL. If you don't have special requirements, it is usually enough just to install PROJ, GEOS and GDAL from repository (rather then compile them manually).

* for mysql support, <source lang="bash" enclose="none">libmysqlclient-dev</source> is required
<source lang="bash">
sudo apt-get install libmysqlclient-dev
</source>

* for netcdf support, <source lang="bash" enclose="none">netcdf-bin</source> and <source lang="bash" enclose="none">libnetcdf-dev</source> is required
<source lang="bash">
sudo apt-get install netcdf-bin libnetcdf-dev
</source>

* for {{AddonCmd|i.spec.unmix}} Addon support, install LAPACK and BLAS:
<source lang="bash">
sudo apt-get install libblas-dev liblapack-dev
</source>

* create a directory as a simple user where all source code is going to be stored -- in this example, a directory named <source lang="bash" enclose="none">src</source> under <source lang="bash" enclose="none">/usr/local</source> is created <source lang="bash">
sudo mkdir /usr/local/src
</source>

* take over directories ownerships ('''replace''' below the terms ''userid'' and ''groupid'' with a real <source lang="bash" enclose="none">userid</source>): <source lang="bash">
sudo chown userid:groupid /usr/local/src</source>

* similarly, grant <source lang="bash" enclose="none">rwx</source> (read-write-execute) permissions for our ''userid'' and ''groupid'' onto the <source lang="bash" enclose="none">src</source> directory: <source lang="bash">
sudo chmod ug+rwx /usr/local/src</source>

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL ==

=== PROJ ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
sudo apt-get install libproj-dev proj-data proj-bin
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-proj-share=/usr/local/share/proj/</source> by <source lang="bash" enclose="none">--with-proj-share=/usr/share/proj/</source>

=== GEOS ===

Install the <source lang="bash" enclose="none">dev</source> package:

<source lang="bash">
# probably you also need to additionally install "libgeos-c1v5"
sudo apt-get install libgeos-dev
</source>

* In the call to <source lang="bash" enclose="none">./configure</source> for [[#GRASS|GRASS]], replace <source lang="bash" enclose="none">--with-geos=/usr/local/bin/geos-config</source> by <source lang="bash" enclose="none">--with-geos=/usr/bin/geos-config</source>

=== GDAL ===

Install the <source lang="bash" enclose="none">dev</source> package (possibly without support for datumgrid):

<source lang="bash">
sudo apt-get install libgdal-dev
</source>

For support of WMS in wxGUI install Python GDAL bindings and GDAL executables:
<source lang="bash">
sudo apt-get install python-gdal gdal-bin
</source>

* Install also the required extra packages (note the message: <source lang="bash" enclose="none">The following extra packages will be installed:</source>)
* Look out for packages to be removed by this operation -- this is most likely caused by incompatible package versions. Fix these problems in advance using commands like the following: <source lang="bash">
sudo apt-get install <package>=<required.version></source>

=== GRASS-GIS ===

[[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]]

== Using pre-compiled dev Packages for PROJ, GEOS and GDAL from GIS.lab PPA==

Ivan Mincik has made all required packages available in his [https://launchpad.net/~imincik/+archive/ubuntu/gis PPA]:

<source lang="bash">
sudo add-apt-repository ppa:imincik/gis
sudo apt-get install libproj-dev libgdal-dev python-gdal libgeos-dev
</source>

Now you can either also install GRASS GIS from there or compile it yourself (see [[Compile_and_Install_Ubuntu#GRASS_GIS|Jump to sub-section GRASS-GIS below]])

== Compile from source ==

=== PROJ ===

* within the directory <source lang="bash" enclose="none">/usr/local/src</source> (create it if it does not exist) checkout <source lang="bash" enclose="none">proj</source> from its GitHub repository: <source lang="bash">
https://github.com/OSGeo/PROJ/
</source>

* get [http://download.osgeo.org/proj/proj-datumgrid-1.8.zip '''proj-datumgrid-1.8.zip'''] or related files from [https://trac.osgeo.org/proj proj' trac] and move it under <source lang="bash" enclose="none">proj/nad</source>
<ul><source lang="bash">
wget http://download.osgeo.org/proj/proj-datumgrid-1.8.zip
mv proj-datumgrid-1.8.zip /usr/local/src/proj/nad
cd /usr/local/src/proj/nad
</source>
</ul>

* decompress it <source lang="bash">
unzip proj-datumgrid-1.8.zip
</source>

* go back to the <source lang="bash" enclose="none">proj</source> directory <source lang="bash">
cd /usr/local/src/proj
</source>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* ensure that <source lang="bash" enclose="none">/usr/local/lib</source> is added to <source lang="bash" enclose="none">/etc/ld.so.conf</source> and afterwards run <source lang="bash">
sudo ldconfig
</source>

* finally, go back to the parent directory simply by instructing<source lang="bash">
cd ..
</source>

=== GEOS ===

* download '''geos-3.12.2.tar.bz2''' from [https://libgeos.org/ https://libgeos.org/] using <source lang="bash" enclose="none">wget</source> <source lang="bash">
wget https://download.osgeo.org/geos/geos-3.12.2.tar.bz2
</source>

* move to the "source-code" directory and decompress
<ul><source lang="bash">
cd /usr/local/src/
bunzip2 geos-3.12.2.tar.bz2
tar xvf geos-3.12.2.tar
</source>
</ul>

* if required, clean previous configuration & compilation <source lang="bash">
make distclean
</source>

* move to geos directory <source lang="bash">
cd geos-3.12.2
</source>

* simple configure, compile and install <source lang="bash">
./configure && make && sudo make install
</source>
<ul> or <source lang="bash">
./configure && make -j2 && sudo checkinstall
</source>
</ul>

* do not forget to execute <source lang="bash">
sudo ldconfig
</source>

=== GDAL ===

'''Note''', GDAL must be compiled '''without''' GRASS support!

* download the current stable version (see https://github.com/OSGeo/gdal/releases for latest version):
<source lang="bash">
wget https://github.com/OSGeo/gdal/releases/download/v3.9.1/gdal-3.9.1.tar.gz
</source>

Follow the instructions to compile GDAL:
https://gdal.org/development/building_from_source.html

=== GRASS GIS ===

Note the differences between different GRASS GIS version (branches) in download and cofiguration. Note also the changes required if you installed some of the dependencies from packages (rather then compiled them yourself).

To fully understand the build process, read the <code>INSTALL</code> file, which is located in GRASS' source code root directory.

''' Getting GRASS' source code '''

Select from one of the GRASS GIS versions and download the source code:

https://github.com/OSGeo/grass/releases/

''' Configure, Compile and Install'''

Enter the directory with the source code, for example:

<source lang="bash">
cd grass
</source>

* '''GRASS GIS example configuration''' (which can/should be adjusted according to specific needs):
<ul>
<source lang="bash">
CFLAGS="-O2 -Wall" LDFLAGS="-s" ./configure \
--with-nls \
--with-cxx \
--with-proj-share=/usr/local/share/proj/ \
--with-geos=/usr/local/bin/geos-config \
--with-wxwidgets \
--with-cairo \
--with-opengl-libs=/usr/include/GL \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
--with-postgres=yes --with-postgres-includes="/usr/include/postgresql" \
--with-sqlite=yes \
--with-mysql=yes --with-mysql-includes="/usr/include/mysql" \
--with-odbc=no \
--with-pdal
</source>
</ul>
<ul>
'''Note''', the above configuration uses the <code>PROJ</code> and <code>GEOS</code> packages compiled from the source. In the case that pre-compiled versions from the repository are required, remove the above corresponding lines to use the "defaults", i.e. (note the backslashe at the end of each line)
<source lang="bash">
--with-proj-share=/usr/share/proj \
--with-geos=/usr/bin/geos-config \
</source>
</ul>

* compile & install <source lang="bash">
make -j2 && sudo make install && sudo ldconfig
</source>

<ul> or <source lang="bash">
make -j2 && sudo checkinstall && sudo ldconfig
</source>
</ul>

For subsequent updates execute (not need for the first time):
<source lang="bash">
svn up
make -j2 && sudo make install && sudo ldconfig
</source>

Sometimes, it is required to clean previous configuration and compilation:
<source lang="bash">
make distclean
svn up
./configure ... # (use the configure command above)
make -j2 && sudo make install && sudo ldconfig
</source>

=== GDAL-GRASS-Plugin ===

See: https://github.com/OSGeo/gdal-grass

* get the plugin from [https://github.com/OSGeo/gdal-grass/releases GitHub]: "gdal-grass-X.Y.Z.tar.gz" using <source lang="bash" enclose="none">wget</source>
<ul><source lang="bash">
# update version number accordingly!
wget https://github.com/OSGeo/gdal-grass/archive/refs/tags/1.0.2.tar.gz -O gdal-grass-1.0.2.tar.gz
tar xvzf gdal-grass-1.0.2.tar.gz
cd gdal-grass-1.0.2
</source></ul>

* create <source lang="bash" enclose="none">/etc/ld.so.conf.d/grass.conf</source> or add in <source lang="bash" enclose="none">/etc/ld.so.conf</source> the GRASS library path:
<ul><source lang="bash">
# GRASS GIS stable library path (adapt as needed)
/usr/local/src/releasebranch_8_4/lib

# GRASS GIS development version library path (adapt as needed)
/usr/local/src/grass_master/lib
</source></ul>

* optionally, clean previous configurations/compilations<source lang="bash">
make distclean</source>

* configure -- point to GRASS installation/binaries
<ul><source lang="bash"> ./configure \
--prefix=/usr/local \
--with-gdal=/usr/local/bin/gdal-config \
--with-grass=/usr/local/grass/ \
--with-autoload="/usr/local/lib64/gdalplugins/" \
--with-ld-shared="g++ -shared"</source></ul>
</ul>

* compile & install using checkinstall<source lang="bash">
make -j2 && sudo checkinstall</source>

= Post compilation/installation control =

* For a recommended quick-check read the [https://grass.osgeo.org/wiki/Compile_and_install_GRASS_and_QGIS_with_GDAL/OGR_Plugin#Troubleshooting Troubleshooting] section at [https://grass.osgeo.org/wiki/Compile_and_install_GDAL-GRASS_plugin Compile_and_install_GDAL-GRASS_plugin]

* in case of errors in future compilation attempts, remember to remove program binaries and files created with the "configuration" from previous compilations with
make distclean

* another common mistake is compiling a module against some GRASS version and then try to run it through another GRASS version. The solution is to recompile the affected module or, in case there are multiple GRASS installations, set up properly LD_LIBRARY_PATH paths.

= Removal of GRASS =

To get rid of a GRASS binaries installation, delete (update version numbers accordingly)
* <source lang="bash" enclose="none">/usr/local/grass</source> (directory, binaries location)
* <source lang="bash" enclose="none">/usr/local/bin/grass</source> (file)
* <source lang="bash" enclose="none">/home/username/.grassrc8</source> (file)

If wanted, delete also the complete source code:
* <source lang="bash" enclose="none">/usr/local/src/grass_release</source> (directory, source code location)

To remove <code>grass</code> (or any other package) which was installed by <source lang="bash" enclose="none">checkinstall</source>, use <source lang="bash" enclose="none">dpkg</source>, e.g.<source lang="bash">
sudo dpkg -r grass # package name defined at installation is important</source>
