[[TOC]] == 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 [http://download.osgeo.org/osgeo4w/osgeo4w-setup.exe 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 (?)) 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) 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) 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: * '''bin-utils''' from [http://downloads.sourceforge.net/mingw/binutils-2.19.1-mingw32-bin.tar.gz here] * '''gcc-core''' from [http://downloads.sourceforge.net/mingw/gcc-core-3.4.5-20060117-3.tar.gz here] * '''gcc-g++''' from [http://downloads.sourceforge.net/mingw/gcc-g++-3.4.5-20060117-3.tar.gz here] * '''mingw32-make''' from [http://downloads.sourceforge.net/mingw/mingw32-make-3.81-20080326-3.tar.gz here] * '''mingw-runtime''' from [http://downloads.sourceforge.net/mingw/mingwrt-3.15.2-mingw32-dev.tar.gz here] * '''mingw-utils''' from [http://downloads.sourceforge.net/mingw/mingw-utils-0.3.tar.gz here] * '''w32api''' from [http://downloads.sourceforge.net/mingw/w32api-3.13-mingw32-dev.tar.gz here] 7. Unpack all to c:\osgeo4w 8. Download an updated '''make''' from [http://downloads.sourceforge.net/mingw/make-3.81-MSYS-1.0.11-2.tar.bz2 here] (required for grass-7.0.svn) 9. Unpack to c:\osgeo4w\apps\msys === Pre-built Binaries === Download: * '''bison''' from [http://downloads.sourceforge.net/gnuwin32/bison-2.1-bin.zip here] * '''bison-deps''' from [http://downloads.sourceforge.net/gnuwin32/bison-2.1-dep.zip here] * '''flex''' from [http://downloads.sourceforge.net/gnuwin32/flex-2.5.4a-1-bin.zip here] * '''gettext-bin''' from [http://downloads.sourceforge.net/gnuwin32/gettext-0.14.4-bin.zip here] * '''gettext-lib''' from [http://downloads.sourceforge.net/gnuwin32/gettext-0.14.4-lib.zip here] * '''libintl-bin''' from [http://downloads.sourceforge.net/gnuwin32/libintl-0.14.4-bin.zip here] * '''libintl-lib''' from [http://downloads.sourceforge.net/gnuwin32/libintl-0.14.4-lib.zip here] * '''regex''' from [http://downloads.sourceforge.net/gnuwin32/regex-2.7-bin.zip here] Unpack all to c:\osgeo4w == Compiling and Installing GRASS (6.4.0) == 1. Download the latest GRASS 6.4.0 source code from [http://grass.osgeo.org/grass64/source/snapshot/ here]. 2. Unpack to c:\osgeo4w\usr\src 3. 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 \ }}} 5. 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 }}} When finished, you should have the following compilation log (c:\osgeo4w\usr\src\grass-6.4xxx\error.log): {{{ GRASS GIS compilation log ------------------------- Started compilation: Mon Feb 16 10:11:17 GMT 2009 -- Errors in: /usr/local/src/grass-6.4.0/raster/r.li/r.li.daemon /usr/local/src/grass-6.4.0/raster/r.li/r.li.edgedensity /usr/local/src/grass-6.4.0/raster/r.li/r.li.patchdensity /usr/local/src/grass-6.4.0/raster/r.li/r.li.patchnum /usr/local/src/grass-6.4.0/raster/r.li/r.li.shape /usr/local/src/grass-6.4.0/raster/r.li/r.li.simpson /usr/local/src/grass-6.4.0/raster/r.li/r.li.shannon /usr/local/src/grass-6.4.0/raster/r.li/r.li.mps /usr/local/src/grass-6.4.0/raster/r.li/r.li.mpa /usr/local/src/grass-6.4.0/raster/r.li/r.li.padcv /usr/local/src/grass-6.4.0/raster/r.li/r.li.padsd /usr/local/src/grass-6.4.0/raster/r.li/r.li.padrange /usr/local/src/grass-6.4.0/raster/r.li/r.li.cwed /usr/local/src/grass-6.4.0/raster/r.li/r.li.richness /usr/local/src/grass-6.4.0/raster/r.li/r.li.dominance -- In case of errors please change into the directory with error and run 'make'. If you get multiple errors, you need to deal with them in the order they appear in the error log. If you get an error building a library, you will also get errors from anything which uses the library. -- Finished compilation: Mon Feb 16 10:11:17 GMT 2009 make: *** [default] Error 1 }}} Currently r.li.* cannot be compiled on Windows, but grass will run fine without them. 6. Because of these errors in the install script stops. To finish it type: {{{ make install }}} Now GRASS should 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, you'll need a different start-up file. 1. Open '''C:\OSGeo4W\apps\grass\bin\grass64''' and at line 24 add: {{{ # Set the PYTHONPATH PYTHONPATH="$GISBASE/etc/python:$PYTHONPATH" }}} 2. To start grass, 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 [http://grass.osgeo.org/wiki/Working_with_SVN Working with SVN]. 1. Download '''Collabnet Subversion Command-Line Client (1.6)''' from [http://www.collab.net/downloads/subversion/ 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 [http://tortoisesvn.tigris.org/ here]. === Grass-6.5.svn (develbranch_6) === 1. Download the grass-6.5.svn source tree with: * subversion (also see [wiki:DownloadSource here] {{{ cd /osgeo4w/usr/src svn co http://svn.osgeo.org/grass/grass/branches/develbranch_6/ grass6-devel #For Subsequent updates, type: cd /osgeo4w/usr/src/grass6-devel svn up }}} OR * Download a daily snapshot from [http://grass.osgeo.org/grass65/source/snapshot/ here] 2. 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 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 [wiki:DownloadSource here] {{{ cd /osgeo4w/usr/src svn checkout https://svn.osgeo.org/grass/grass/trunk grass_trunk #For Subsequent updates, type: cd /osgeo4w/usr/src/grass_trunk svn up }}} OR * Download a daily snapshot from [http://grass.osgeo.org/grass70/source/snapshot/ 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\lib\python\grass.py, and at line 208 change: {{{ os.execvp("g.parser", [name] + argv) }}} To: {{{ os.execvp("g.parser.exe", [name] + argv) }}} 4. Open c:\osgeo4w\usr\src\grass_trunk\include\Make\Multi.make, at at line 19 change: {{{ $(BIN)/%$(EXE): $(DEPENDENCIES) $(call linker) define objs_rule $(BIN)/$(1)$(EXE): $$(patsubst %.o,$(OBJDIR)/%.o,$$($$(subst .,_,$(1)_OBJS))) }}} To: {{{ define objs_rule $(BIN)/$(1)$(EXE): $$(patsubst %.o,$(OBJDIR)/%.o,$$($$(subst .,_,$(1)_OBJS))) $(DEPENDENCIES) $$(call linker) }}} 5. Download the package.sh script from [http://trac.osgeo.org/grass/browser/grass/branches/develbranch_6/mswindows/osgeo4w/package.sh?format=raw here] 6. Put in c:\osgeo4w\usr\src\grass_trunk\mswindows\osgeo4w\ (you may have to create the latter two folders) 7. 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 8. Also, at line 35 change: {{{ --with-freetype-includes=/osgeo4w/include/freetype2 }}} To: {{{ --with-freetype-includes=/osgeo4w/include/freetype2 \ --without-cairo \ --without-geos }}} 9. To compile, type in MSYS console: {{{ cd /osgeo4w/usr/src/grass_trunk ./mswindows/osgeo4w/package.sh }}} 10. Once the scripts fails on the r.li.* errors (see above), type: {{{ make install }}} 11. Once this is finished open c:\osgeo4w\apps\grass\grass-7.0.svn\etc\Init.sh, and at line 150 change: {{{ PATH="$GRASS_LD_LIBRARY_PATH" }}} To: {{{ PATH="$GRASS_LD_LIBRARY_PATH:$PATH" }}} 12. Open c:\osgeo4w\apps\grass\bin\grass70, and at line 25 add: {{{ # Set the PYTHONPATH PYTHONPATH="$GISBASE/etc/python:$PYTHONPATH" }}} 13. 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 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 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}}}|| == TODO == * QGIS * Add cairo support to grass-7.0.svn * Possibly use these cairo binaries [http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/cairo-1.6.4-2.zip deps] and [http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/cairo-dev-1.6.4-2.zip bin]. * 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 [wiki:CompileOnWindowsMSVC] == See also == * [http://trac.osgeo.org/osgeo4w/wiki/pkg-grass GRASS package page in OSGeo4W] (including [http://trac.osgeo.org/osgeo4w/wiki/pkg-grass#PackagerNotes packaging notes]) * [wiki:BuildingOnWindows Develop your own GRASS modules on MS-Windows] * http://wiki.qgis.org/qgiswiki/BuildingFromSource by QGIS Team * http://www.webalice.it/marco.pasetti/grass/BuildFromSource.html by Marco Pasetti * http://www.webalice.it/marco.pasetti/qgis+grass/BuildFromSource.html by Marco Pasetti
