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.
  1. Run the installer.
  1. Select Advanced Install, and Next.
  1. 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 (?))
  1. Select grass from the desktop section (this is a binary but we'll compile from source later).
  1. 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
  1. 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)
  1. Type:
     mkdir /c/osgeo4w/apps/msys/osgeo4w
    
  2. Copy c:\osgeo4w\apps\msys\etc\fstab.sample to c:\osgeo4w\apps\msys\etc\fstab (without .sample)
  1. Open c:\osgeo4w\apps\msys\etc\fstab
  1. At line 16, change:
    c:/mingw		/mingw
    c:/ActiveState/perl	/perl
    

To:

c:/osgeo4w/	/osgeo4w
  1. Download the MinGW packages:

(updates may be found here)

  1. Unpack all to c:\osgeo4w
  1. Download an updated make from here (required for grass-7.0.svn)

(updates may be found here)

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

Pre-built Binaries

Download: (updates may be found 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.
  1. Unpack to c:\osgeo4w\usr\src
  1. Open c:\osgeo4w\usr\src\grass64\mswindows\osgeo4w\package.sh and at line 12, change:
    --with-libs="/c/OSGeo4W/lib /c/MinGW/lib" \
    --with-includes="/c/OSGeo4W/include /c/MinGW/include" \
    

To:

--with-libs=/c/OSGeo4W/lib \
--with-includes=/c/OSGeo4W/include \
  1. To compile, type in MSYS console:
    export PATH="/osgeo4w/bin:$PATH"
    cd /osgeo4w/usr/src/grass-6.4xxx (change to dir of the version you downloaded)
    ./mswindows/osgeo4w/package.sh
    
  1. Check error.log for any error messages and package.log if you're having problems.

GRASS should now be installed in c:\osgeo4w\apps\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)
  1. Run the installer and install to a path without spaces(?) such as c:/Subversion or c:/Programs/Subversion
  1. 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 http://svn.osgeo.org/grass/grass/branches/develbranch_6/ grass6-devel
      

OR

  • Download a weekly snapshot from here
  1. Follow the instructions above for grass-6.4.0, but change all grass64 to grass65, etc.

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

cd /osgeo4w/usr/src/grass6-devel
make distclean
svn up
rm 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")
  1. Open c:\osgeo4w\etc\ini\msys.bat and at line 3 add:
    set PYTHONPATH=%OSGEO4W_ROOT%\apps\Python25
    
  1. 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
  1. 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
    
  1. 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 configure-stamp
./mswindows/osgeo4w/package.sh

Troubleshooting

Here are a few common problems and their solutions:

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

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)
