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:
- Download the OSGeo4W installer from here.
- Run the installer.
- Select Advanced Install, and Next.
- 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 (?))
- Select grass from the desktop section (this is a binary but we'll compile from source later).
- 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
- Click next, the selected packages and their required subpackages will be downloaded and installed automatically.
Install the environment for compilation (MingW)
- Run msys (there should be an icon on the desktop)
- type:
mkdir /c/osgeo4w/apps/msys/osgeo4w
- Copy c:\osgeo4w\apps\msys\etc\fstab.sample to c:\osgeo4w\apps\msys\etc\fstab (without .sample)
- Open c:\osgeo4w\apps\msys\etc\fstab
- At line 16, change:
c:/mingw /mingw c:/ActiveState/perl /perl
To:
c:/osgeo4w/ /osgeo4w
- Download the MinGW packages:
- Unpack all to c:\osgeo4w
- Download an updated make from here (required for grass-7.0.svn)
- Unpack to c:\osgeo4w\apps\msys
Pre-built Binaries
Download:
- bison from here
- bison-deps from here
- flex from here
- gettext-bin from here
- gettext-lib from here
- libintl-bin from here
- libintl-lib from here
- regex from here
Unpack all to c:\osgeo4w
Compiling and Installing GRASS (6.4.0)
- Download the latest GRASS 6.4.0 source code from here.
- Unpack to c:\osgeo4w\usr\src
- 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 \
- To compile, type in MSYS console:
export PATH="/osgeo4w/bin:$PATH" cd /osgeo4w/usr/src/grass-6.4xxx (change to dir of the version you downloaded) ./mswindows/osgeo4w/package.sh
When finished, you should have the following compilation log (c:\osgeo4w\usr\src\grass-6.4xxx\error.log):
GRASS GIS compilation log ------------------------- Started compilation: Mon Feb 16 10:11:17 GMT 2009 -- Errors in: /usr/local/src/grass-6.4.0/raster/r.li/r.li.daemon /usr/local/src/grass-6.4.0/raster/r.li/r.li.edgedensity /usr/local/src/grass-6.4.0/raster/r.li/r.li.patchdensity /usr/local/src/grass-6.4.0/raster/r.li/r.li.patchnum /usr/local/src/grass-6.4.0/raster/r.li/r.li.shape /usr/local/src/grass-6.4.0/raster/r.li/r.li.simpson /usr/local/src/grass-6.4.0/raster/r.li/r.li.shannon /usr/local/src/grass-6.4.0/raster/r.li/r.li.mps /usr/local/src/grass-6.4.0/raster/r.li/r.li.mpa /usr/local/src/grass-6.4.0/raster/r.li/r.li.padcv /usr/local/src/grass-6.4.0/raster/r.li/r.li.padsd /usr/local/src/grass-6.4.0/raster/r.li/r.li.padrange /usr/local/src/grass-6.4.0/raster/r.li/r.li.cwed /usr/local/src/grass-6.4.0/raster/r.li/r.li.richness /usr/local/src/grass-6.4.0/raster/r.li/r.li.dominance -- In case of errors please change into the directory with error and run 'make'. If you get multiple errors, you need to deal with them in the order they appear in the error log. If you get an error building a library, you will also get errors from anything which uses the library. -- Finished compilation: Mon Feb 16 10:11:17 GMT 2009 make: *** [default] Error 1
Currently r.li.* cannot be compiled on Windows, but grass will run fine without them.
- Because of these errors in the install script stops. To finish it type:
make install
Now GRASS should be installed in c:\osgeo4w\apps\grass-6.4.0\
Usage
To start grass use the icon on the desktop.
OR, if you want to be able to use the command line from within grass, you'll need a different start-up file.
- Open C:\OSGeo4W\apps\grass\bin\grass64 and at line 24 add:
# Set the PYTHONPATH PYTHONPATH="$GISBASE/etc/python:$PYTHONPATH"
- 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 Working with SVN.
- Download Collabnet Subversion Command-Line Client (1.6) from here. (You'll have to register on Collabnet)
- Run the installer and install to a path without spaces(?) such as c:/Subversion or c:/Programs/Subversion
- 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
Grass-6.5.svn (develbranch_6)
- 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
For Subsequent updates, type:
cd /osgeo4w/usr/src/grass6-devel svn up
OR
- Download a daily snapshot from here
- Follow the instructions above for grass-6.4.0, but change all grass64 to grass65, etc.
Grass-7.0.svn (trunk)
- 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
For Subsequent updates, type:
cd /osgeo4w/usr/src/grass_trunk svn up
OR
- Download a daily 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")
- Open c:\osgeo4w\etc\ini\msys.bat and at line 3 add:
set PYTHONPATH=%OSGEO4W_ROOT%\apps\Python25
- 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)
- 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)
- Download the package.sh script from here
- Put in c:\osgeo4w\usr\src\grass_trunk\mswindows\osgeo4w\ (you may have to create the latter two folders)
- 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
- Also, at line 35 change:
--with-freetype-includes=/osgeo4w/include/freetype2
To:
--with-freetype-includes=/osgeo4w/include/freetype2 \ --without-cairo
- To compile, type in MSYS console:
cd /osgeo4w/usr/src/grass_trunk ./mswindows/osgeo4w/package.sh
- Once the scripts fails on the r.li.* errors (see above), type:
make install
- 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:$PATH"
- Open c:\osgeo4w\apps\grass\bin\grass70, and at line 25 add:
# Set the PYTHONPATH PYTHONPATH="$GISBASE/etc/python:$PYTHONPATH"
- You're finished, start with:
/osgeo4w/apps/grass/bin/grass70

- QGIS
- Add cairo support to grass-7.0.svn
