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:

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)
- 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

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:

(updates may be found 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

Unpack all to c:\osgeo4w

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

(updates may be found here)

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
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

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

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

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

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

Download a weekly snapshot from here

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)

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

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")

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\mswindows\osgeo4w\package.sh, and make the same changes as in the grass-6.4.0 section above
