Compiling GRASS on MS-Windows

Dependencies required for building with MinGW

Compiling your own copy of GRASS is greatly simplified by using the OSGeo4W directory structure to install most dependencies and downloading the rest from a few other locations. Follow the steps below to set up the build environment for GRASS.

Install the OSGeo4W directory structure

OSGeo4W has several of the required dependencies for compiling GRASS:

1. Download the OSGeo4W installer from ​here.

2. Run the installer.

3. Select Advanced Install, and Next.

4. Set the install directory to c:\OSGeo4W (other directories or fine if there are no spaces in the path but make sure to adjust the instructions below (?)). The MSys maintainers have made it clear that they ​will not support spaces in path names nor accept patches fixing those issues. With some patches to msys.bat however it is possible to install a built GRASS into C:\Program Files\.

5. Select grass from the desktop section (this is a binary but we'll compile from source later).

6. Also select:

• Commandline_Utilities
  • avce00
  • gpsbabel

• Libs:
  • fftw-devel
  • freetype-devel
  • freetype-devel-mingw
  • gsl-libs
  • gsl-devel
  • libpng-devel
  • libpng-devel-mingw
  • libtiff-devel
  • libxdr
  • mingw-libs (contains mingw-style libraries for VC build binaries and depends on gdal, libpq, libjpeg-devel, sqlite3, libtiff, zlib, proj)
  • pdcurses-devel
  • tcltk-devel
  • zlib-devel

7. Click next, the selected packages and their required subpackages will be downloaded and installed automatically.

Install the environment for compilation (MingW)

1. Run msys (there should be an icon on the desktop)
   • Note for Vista 64bit: in case that MSYS starts to open multiple windows, close them all. Check first ​this discussion. A solutions seems to be to download ​http://downloads.sourceforge.net/mingw/MSYS-1.0.11-20070729.tar.bz2 (or newer?). Open the tarball, and copy the bin directory over C:\osgeo4w\apps\msys\bin. see also ​https://sourceforge.net/forum/forum.php?forum_id=720513

2. Type:

   mkdir /c/osgeo4w/apps/msys/osgeo4w
   

3. Copy c:\osgeo4w\apps\msys\etc\fstab.sample to c:\osgeo4w\apps\msys\etc\fstab (without .sample)

cd /c/OSGeo4W/apps/msys/etc/
cp fstab.sample fstab

4. Open c:\osgeo4w\apps\msys\etc\fstab

5. At line 16, change:

   c:/mingw		/mingw
   c:/ActiveState/perl	/perl
   

To:

c:/osgeo4w/	/osgeo4w

6. Download the MinGW packages:

(​updates may be found here)

• Temp bugfix (see ​here), msysCORE-1.0.11-bin from ​here
• bin-utils from ​here
• gcc-core from ​here
• gcc-g++ from ​here
• mingw32-make from ​here
• mingw-runtime from ​here
• mingw-utils from ​here
• w32api from ​here

7. Unpack all to c:\osgeo4w

8. Download an updated make from ​here (required for grass-7.0.svn)

(​updates may be found here)

9. Unpack to c:\osgeo4w\apps\msys

Pre-built Binaries

Download: (​updates may be found here)

• bison from ​here
• bison-deps from ​here
• flex from ​here
• gettext-bin from ​here
• gettext-lib from ​here
• libiconv-lib from ​here
• libintl-bin from ​here
• libintl-lib from ​here
• regex from ​here
• bc from ​here
• readline from ​here

Unpack all to c:\osgeo4w

Compiling and Installing GRASS (6.4.0)

1. Download the latest GRASS 6.4.0 source code from ​here.

2. Unpack to c:\osgeo4w\usr\src

3. To compile, type in MSYS console:

For compiling in the MSYS-environment, lines 94-136 in package.sh should be commented out.

cd /osgeo4w/usr/src/grass-6.4xxx (change to dir of the version you downloaded)
./mswindows/osgeo4w/package.sh

4. Check error.log for any error messages and mswindows/osgeo4w/package.log if you're having problems.

GRASS should now be installed in c:\osgeo4w\apps\grass\grass-6.4.0\

Usage

To start grass use the icon on the desktop.

OR, if you want to be able to use the command line from within grass

1. Type in MSYS console:

   /osgeo4w/apps/grass/bin/grass64
   

Or to use the new wxpython GUI:

/osgeo4w/apps/grass/bin/grass64 -wxpython

Compiling and Installing Development Versions of GRASS

Optional Installation of Subversion

The GRASS source tree is stored in an online repository called Subversion. Rather than downloading source trees from the website, subversion lets you keep up to date, and manage your modifications, with simply commands. For more see ​Working with SVN.

1. Download Collabnet Subversion Command-Line Client (1.6) from ​here. (You'll have to register on Collabnet)

2. Run the installer and install to a path without spaces(?) such as c:/Subversion or c:/Programs/Subversion

3. Open c:\osgeo4w\etc\ini\msys.bat and at line 1 add the path to your subversion folder, eg. change:

   PATH %PATH%;%OSGEO4W_ROOT%\apps\msys\bin
   

To:

PATH %PATH%;%OSGEO4W_ROOT%\apps\msys\bin;/c/Programs/Subversion

Alternatively TortoiseSVN, a plugin for Windows Explorer, can be used for managing the local source tree. Download ​here.

Grass-6.5.svn (develbranch_6)

1. Download the grass-6.5.svn source tree with:
   • subversion (also see here)

     cd /osgeo4w/usr/src
     svn co https://svn.osgeo.org/grass/grass/branches/develbranch_6/ grass6-devel
     

OR

• Download a weekly snapshot from ​here

2. Follow the instructions above for grass-6.4.0, but change all grass64 to grass65 etc. Note also that the line numbers may differ slightly between GRASS 6.4.0svn (releasebranch_6_4) and GRASS-6.5.svn (develbranch_6).

nb. To update your source tree later using subversion and recompile type:

cd /osgeo4w/usr/src/grass6-devel
make distclean
svn up
rm mwindows/osgeo4w/configure-stamp
./mswindows/osgeo4w/package.sh

Grass-7.0.svn (trunk)

1. Download the grass-7.0.svn source tree with:
   • subversion (also see here

     cd /osgeo4w/usr/src
     svn checkout https://svn.osgeo.org/grass/grass/trunk grass_trunk
     

OR

• Download a weekly snapshot from ​here and unpack to c:\osgeo4w\usr\src (if you use this method in the instructions below change "grass_trunk" to the folder name of your snapshot eg. "grass-7.0.svn_src_snapshot_2009_03_29")

2. Open c:\osgeo4w\etc\ini\msys.bat and at line 3 add:

   set PYTHONPATH=%OSGEO4W_ROOT%\apps\Python25
   

3. Open c:\osgeo4w\usr\src\grass_trunk\mswindows\osgeo4w\package.sh, and make the same changes as in the grass-6.4.0 section above. Note also that the line numbers may differ slightly between GRASS 6.4.0svn (releasebranch_6_4) and GRASS-7.0.svn (trunk).

4. To compile, type in MSYS console:

   cd /osgeo4w/usr/src/grass_trunk
   ./mswindows/osgeo4w/package.sh
   

• If any errors came up during the compile they will be recorded in error.log. If they are non-critical modules you can finish the installation with:

  make install
  

5. You're finished, start with:

   /osgeo4w/apps/grass/bin/grass70
   

nb. To update your source tree later using subversion and recompile type:

cd /osgeo4w/usr/src/grass_trunk
make distclean
svn up
rm mswindows/osgeo4w/configure-stamp
./mswindows/osgeo4w/package.sh

Troubleshooting

Here are a few common problems and their solutions:

With module...	If you get the error	Do the following
r.mapcalc, r.univar, or raster3d/base	No rule to make target ... needed by 'progs'	Update msys's make (see step 8 in the MinGW section above)
scripts/*	ImportError: No module named grass	Fix PYTHONPATH to *nix-style (eg. PYTHONPATH=/osego4w/apps/Python25)

Creating a WinGRASS Installer

The instructions for creating a WinGRASS native installer (for easy installation on any windows machine) are included in the GRASS source tree at mswindows/README.html.

Or, for version 6.4.0svn (releasebranch_6_4) ​click here

TODO

• QGIS
• Add cairo support to grass-7.0.svn
  • Possibly use these cairo binaries ​deps and ​bin. (check for newer versions)
  • Preferably get cairo added to osgeo4w tree.
• Add geos support for grass-7.0.svn (need geos-config file)

Building with MS Visual Studio

• See CompileOnWindowsMSVC

Errata

• see also ​OSGeo4W pkg-grass buglist

• r.patch and v.patch do not work on 32bit Vista. They exit with a "Bad file number" error. Apparently Windows's security measures think that "patch" is a dangerous word. (see bug #759)
  • Solution 1: Switch of UAC.
  • Solution 2: Rename C:\GRASS\bin\r.patch.exe to r.fuzzy_kittens.exe. Do something similar for v.patch.exe. To keep the menus working you will want to edit the C:\GRASS\etc\wxpython\xml\menudata.xml file as well to match the new names.
