The general idea is to reach a point where GRASS runs in Windows without any kind of unix emulation. Currently, this is possible, but limits the use to compiled modules as scripts are all of unix-shell type and cannot run within a Windows cmd.exe environment without a series of unix tools such as a shell, awk, sed, etc. So in order to run such scripts a collection of unix-like tools needs to be installed, such as Msys or Gnuwin32+Shell.

Another major feature not available in the windows version are the old-style interactive X monitors (i.e. the x0, PNG, PS, Cairo, etc, monitors opened with '<tt>d.mon&nbsp;x0</tt>'). Only direct rendering works currently. Display is thus "limited" to the Tcl/Tk and wxPython GUIs (the latter might still need some cleanup of unix-specific code). Modules like i.points and d.zoom will not work (see [[#Known_Issues]]).

== Installing binary snapshots ==


Regular binary snapshots for windows are available [http://geog-pc40.ulb.ac.be/grass/wingrass/ here]. To install them, just download and unzip. In order to be able to use the graphical user interface, you also have to download and install [http://www.activestate.com/products/activetcl/ ActiveState Tcl].
Regular binary snapshots for Windows are available from the main GRASS [http://grass.osgeo.org/download/software/ms-windows/ download page].
 
You can then launch the GRASS GUI by clicking on the grass63.bat which is in c:\grass\bin\ (or wherever you unzipped the package). This should launch the GUI which gives you access to all GRASS modules.
 
If you like the command line, you can launch Windows' cmd.exe via Start->Run->cmd.exe. Then type 'c:\grass\bin\grass63.bat -text' to launch grass without the GUI. If you want to access the GUI at a later stage, just type 'gis.m'.
 
If you want to have access to shell scripts, you also have to install [http://sourceforge.net/project/downloading.php?groupname=mingw&filename=MSYS-1.0.11-2004.04.30-1.exe Msys] and then adapt the grass63.bat script according to the examples in the file.


== Compiling by yourself ==
== Compiling by yourself ==


(based on work from Paul Kelly - [http://lists.osgeo.org/pipermail/grass-dev/2006-December/028097.html his message])
=== Guide ===
 
... or see new [http://www.webalice.it/marco.pasetti/grass/BuildFromSource.html GRASS Windows Native Binary Building Guide]
 
=== Requirements ===
 
* To compile winGRASS natively, you need the following additional libraries: ''libpng, PROJ.4, GDAL, Zlib, XDR''. They are available in a gzipped tar file (to get started quickly): http://www.stjohnspoint.co.uk/grass/ (get wingrass-extralibs.tar.gz).
* Additionally, you need [http://www.mingw.org/download.shtml Msys & MingW] (current version)
* [http://www.mingw.org/MinGWiki/index.php/bison bison]
* [http://www.mingw.org/MinGWiki/index.php/flex flex]
 
Decompressing bison and flex in the root msys directory should position the files in the correct directories.
 
'''Optionally:'''
* Freetype
* FFTW
* PDCurses
 
''TODO: is PDCurses really optionally?''
 
=== Configuration and compilation ===
 
The prefix where you untar that file you will need to supply to the GRASS configure as:
 
      --with-includes=prefix --with-libs=prefix
 
Before compilation, you need to set your path in msys in order to add the path to the lib/ and bin/ directories of Paul's tarball before compiling. You might also need to edit the first few lines of the gdal-config script in the bin/ directory, to reflect the path where it is actually installed.
 
You also have to erase $(MANDIR) $(MANPAGES) from line 13 of man/Makefile, i.e. 'default: $(MANDIR) $(MANPAGES)' -> 'default:'.
 
If you get an error such as 'cannot open file `/msys/share/bison/m4sugar/m4sugar.m4': No such file or directory', one solution is to move around the msys bison installation a bit, so that m4sugar.m4 is available in the indicated path.
 
A working configure line is:
      ./configure --prefix=c:/grass --bindir=c:/grass/bin \
      --with-includes=/c/grass/forgrass/include \
      --with-libs=/c/grass/forgrass/lib --with-cxx --without-jpeg --without-tiff \
      --without-postgres --with-opengl=windows --without-fftw --without-x \
      --enable-shared=yes --with-tcltk-includes=/c/tcl/include \
      --with-tcltk-libs=/c/tcl/bin
 
The configure line used for the current binary snapshots can be seen [http://geog-pc40.ulb.ac.be/grass/wingrass/winconfig.log here].


Compile with make.
All the information needed for compiling yourself can be found in '''''[http://trac.osgeo.org/grass/wiki/CompileOnWindows Compiling GRASS on MS-Windows]'''''


After compiling you should copy libxdr.dll, libproj.dll, libpng.dll, libgdal-1.dll and libz.dll.1.2.3 into the GRASS lib directory and all the GDAL and PROJ .exe files in the bin directory into the GRASS bin directory, and then you have a more or less self-contained GRASS distribution.
See also '''[http://trac.osgeo.org/grass/wiki/BuildingOnWindows BuildingOnWindows]'''


For the GUI, including for displaying anything, you need to install [http://www.activestate.com/downloads/ Activestate Tcl/Tk] 8.4.13 (in c:\tcl).

* Note the "Important Microsoft Runtime Libraries" option. Some of the software which ships with GRASS will not run if these system libraries are not already present, and unfortuantely Microsoft does not install them by default, you need to install the .Net framework or Visual C++ compiler runtime support to get them. These libraries are not part of GRASS but we give the user the opportunity to download and install them during the install if they are needed. Typically a computer with a lot of software already installed may have them, a new computer is likely to be missing them. If they are not installed the symptom is that the GRASS window momentarily flashes on the screen then disappears at start up, closing before you can see the error message.

* No monitors
* No X monitors in winGRASS 6:


This means that you cannot launch any monitor launched with d.mon (x0, PNG, PS, etc). The only way you can render is directly to a file. But you cannot directly display to screen from the command line. This will be solved in GRASS 7 with a new rendering system and possibly via the new wxgrass GUI. So no work will probably be put into this until then.

This will not however, give you all the information i.class provides, such as the histogram of the region, the statistics and the display of matches. These modules will have to be rewritten to clearly separate display and backend parts, so that the backend can be run on the command line or from any GUI frontend. '''Volunteers needed.'''

Currently recommended is [http://sourceforge.net/project/downloading.php?groupname=mingw&filename=MSYS-1.0.11-2004.04.30-1.exe Msys] as this is a simple install of a package containing everything which is needed.

This page describes the current status of winGRASS 6 development as of mid-2013

Current status - Summary

The native windows port of GRASS is slowly coming to a stage where it can be considered mature beta status. All main functions seem to work, but much more testing is needed. The port is of the current SVN release branch 6 for GRASS 6.4. The only prior native port of an earlier version is 6.3.0.

The general idea is to reach a point where GRASS runs in MS-Windows without any kind of UNIX emulation. Currently this is possible but limits the use to compiled modules, as scripts are all of UNIX-shell type and cannot run within a Windows cmd.exe environment without a series of UNIX tools such as a shell, awk, sed, etc. So in order to run such scripts a collection of UNIX-like tools needs to be installed, such as Msys or Gnuwin32+Shell.

Another major feature not available in the MS-Windows version are the old-style interactive X monitors (i.e. the x0 monitors opened with 'd.mon x0'). Only direct rendering works currently. Display is thus "limited" to the wxPython and Tcl/Tk GUIs. Modules like i.points and d.zoom will not work due to their interactive monitor requirements (see #Known_Issues).

Regular binary snapshots for Windows are available from the main GRASS download page.

Platform specific issues

XP/2000

If the GRASS GUI startup fails with "[Error 14001]" in the MSys terminal on a relatively fresh install of XP, the solution is to install some missing DLL files from Microsoft which apparently don't come standard. If these library files are missing, Quantum GIS and other software from the OSGeo4W stack will likely encounter the same trouble as well.

You'll need to install a number of packages: (in order)

  • MS's Windows Installer 3.1 Redistributable (v2)
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=25

It is recommended to run Windows updates after installing these.

Windows7

  • Missing MSVCR71.dll or MSVCP100.dll library causes GRASS to exit immediately upon startup.
For the solution, see WinGRASS errors

ToDo

Dependencies

GRASS Dependencies
  • add the FFMPEG support in GRASS (reports an error in building OGSF library; probably needs to specify -lavutil in gcc command) ***
Non-Free GDAL Plugins

(can't be shipped as part of the GRASS package directly due to various levels of non-freeness, but can be made into user-installable plugins)

  • ECW support in GDAL */**
  • JPEG2000 support in GDAL (through Jasper or Kadaku *) **
  • OGDI support in GDAL *
  • MrSID support in GDAL */**
GRASS and GDAL Dependencies
  • add the Xerces support in both GDAL and GRASS *
  • add the ODBC support in both GDAL and GRASS */**
  • add the MySQL support in both GDAL and GRASS */**
Miscellaneus Dependencies
  • add the OpenSSL support in both PostgreSQL and SQLite *


* needs to build related libraries from source in MinGW
** needs to check the licences first
*** FFMPEG has been already succesfully built on MinGW

Internal Libraries

  • parser: find out why launching a module from the command line without parameters does not call module GUI

Vector modules

  • v.in.ascii crashes on files with irregular line length (see this thread) - still true, 2014?

Raster modules

  • The wxGUI has an issue when trying to run r.mapcalc with the || "or" operator from the wxGUI built-in command entry box on the command console tab of the Layer Manager. You can work around this by running r.mapcalc using the Map Calculator GUI, or from a real command line (in that case remember to "quote" the expression).
  • The same wxGUI built-in command entry box on the command console tab requires file names with paths to be fully "quoted", e.g. input="C:\data\positions.csv", or else the "\" characters are lost.

GRASS 6 Addons

  • Not all the GRASS Addons are available from the wxGUI extension manager. Problems still exist with running Python scripts. The command line version of g.extension requires the full osgeo4w build environment, which is not installed on most Windows users' computers, so you need to use the pre-built downloads from the wxGUI extension tool. The wxGUI manager will download the nightly pre-built Addon executables (Status of winGRASS 6 Addons availability).

Tcl/Tk issues

Miscellaneous

  • metacharacter escape in "sh -c '$cmd'"
  • Have to type "exit" in the console to save ~/.grassrc file. Then, close gis.m to finish the session.
  • A previous installation of grass under cygwin is likely to cause problems with WinGrass. Follow the directions to remove cygwin at http://cygwin.com/faq/faq-nochunks.html#faq.setup.uninstall-all

Dealing with shell scripts or .bat files

Bourne shell scripts require MSys (or some other Bourne shell), but you don't need to start GRASS from MSys.

The main issue with scripts is that Windows doesn't understand the "#!" notation used to specify the interpreter.

All of the supplied scripts in $GISBASE/scripts have a corresponding .bat file in $GISBASE/bin which invokes script via %GRASS_SH%. This allows you to run those scripts from the Windows command prompt.

If you write scripts of your own, you need to either add a corresponding .bat file, or give the script a .sh extension and associate that with the shell, e.g. via the ftype and assoc commands. You can use the PATHEXT variable to eliminate the need to type the extension.

Other libraries

GDAL

  • lib/gis/OBJ.*/fmode.o is needed for any GRASS related modules.
  • modified ltmain.sh to install binary files from wrapper scripts.
