Eclipse is an Integrated Development Environment (IDE) for software development.

The CDT-plugin enables support for C/C++ development. While CVS-support is built in, additional plugins have to included to allow for access of SVN repositories.

Eclipse/CDT can be used as a convenient frontend for platform independent GRASS GIS development.

It can handle:

  • Checkout of the latest sources from the SVN
  • Code editing and refactoring
  • GRASS-spedific Configure/Make/Make-Install - toolchain via wrapping in Ant-XML-fragements.
  • Running of a freshly compiled GRASS-build from within Eclipse.

Please note: This approach aims at software development, not the development of a fat GRASS plugin within the Eclipse environment. If this is you interest, you might want to look up the JGRASS project.

What's needed -- Howto

  • A sample Ant-wrapper-file -> paths etc which needs to be updated to local settings (see below). It's pretty much self explanatory. The file should be included in the Eclipse-project (top level).
  • The build process is started from the GUI via ->Run ->External Tools ->Run As -> AntBuild -> Select the file "build.xml" here.
  • When invoked, the file defaults to do the configuration step and stops afterwards.
  • Use the OUTLINE window to fire up the following steps of compilation etc.
  • The tasks (configure/make/make install) can also be concatenated -> "launch" shows how this is done: It includes the whole building chain and eventually starts the newly build GRASS from within Eclipse.

Note: Please be aware that building on a Windows machine will require a bit of fiddling with MSYS. The attached build.xml comes from a linux-environment.
