Compiling GRASS on MS-Windows

Dependencies required for building with MinGW

Compiling your own copy of GRASS is greatly simplified by using the MSYS2 and 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 GIS.

Install the OSGeo4W directory structure

OSGeo4W has several of the required dependencies for compiling GRASS GIS:

Download the OSGeo4W installer - 32bit or 64bit

Run the installer.

Select Advanced Install, and Next.

Set the install directory to C:\OSGeo4W (32bit) or C:\OSGeo4W64 (64bit) (other directories are 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\.

Select:
- cairo
- gdal
- geos
- fftw
- fftw-devel (32bit only)
- freetype-devel
- freetype-devel-mingw (32bit only)
- iconv
- libjpeg
- liblas-devel
- libpng
- libpq
- libtiff
- libxdr
- pdcurses
- proj
- regex-devel
- sqlite3
- zlib

Optionally select also GDAL plugins for common GIS formats (be careful not to introduce GPL incompatibilities)
- gdal-ecw
- gdal-mrsid

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

Install the MSYS2 directory structure

MSYS2 has several of the required dependencies for compiling GRASS GIS (like gcc and others):

Download and install MSYS2 - 32bit or 64bit.

Start MSYS2 terminal and install requirements (both 32bit and 64bit):

pacman -S tar libintl make bison diffutils subversion dos2unix zip

Install MinGW-w64 toolchain:

32bit:

pacman -S mingw-w64-i686-toolchain mingw-w64-i686-cairo mingw-w64-i686-python2-numpy mingw-w64-i686-sqlite3

64-bit:

pacman -S mingw-w64-x86_64-toolchain mingw-w64-x86_64-cairo mingw-w64-x86_64-python2-numpy mingw-w64-x86_64-sqlite3

Compiling and Installing GRASS GIS

Start MSYS2 terminal - mingw32_shell.bat (32bit) or mingw64_shell.bat (64bit).

Download GRASS source code (see wiki:DownloadSource for details). Example for development version (trunk):

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

Switch to GRASS GIS source code directory (in our case grass_trunk) and run package.sh compilation script:

cd grass_trunk

# for release builds on 32bit
./mswindows/osgeo4w/package.sh

# for daily builds on 32bit
PACKAGE_POSTFIX=-daily ./mswindows/osgeo4w/package.sh

# for release builds on 64bit
OSGEO4W_POSTFIX=64 ./mswindows/osgeo4w/package.sh

# for daily builds on 64bit
PACKAGE_POSTFIX=-daily OSGEO4W_POSTFIX=64 ./mswindows/osgeo4w/package.sh

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

GRASS GIS should now be installed in c:\osgeo4w\apps\grass\grass-7.1.svn.

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 cmd console (assuming that we compiled GRASS 7.1):

c:\osgeo4w\bin\grass71svn.bat

Creating a WinGRASS Installer

The instructions for creating a WinGRASS native installer (self-contained package installer) using the scripts contained in the mswindows directory. In order to avoid mistakes or misunderstandings, we highly recommend to follow each step and command exactly as they are written in this document. See also scripts used for daily builds.

Install MSYS2/OSGeo4W Tree and Compile GRASS

First of all download the MSYS2, OSGeo4W installers, install the required dependencies, and build GRASS GIS from source (see notes above). Do not move on to step two until you have successfully tested your new version of GRASS.

Create a GRASS self-contained Package

Copy all the content of the mswindows directory to a temporary directory, for example c:\temp.

Launch the file c:\temp\GRASS-Packager.bat.

When finished, you should have a GRASS self-contained release package in c:\temp\GRASS-<Version>-Package, e.g. c:\temp\GRASS-70-Package.

Install NSIS

Download the NSIS installer

Install to c:\DevTools

Install NSIS: Untgz Plugin

Download the NSIS Untgz Plugin

Copy untgz.dll to c:\DevTools\Plugins

Install NSIS: AccessControl Plugin

Download the NSIS AccessControl Plugin

Unzip to c:\DevTools\

Create the WinGRASS Installer

Launch c:\temp\GRASS-Installer.nsi.

When finished, you should have the WinGRASS installer in c:\temp.

Required by GRASS Addons v.in.redwg .

Hints

Startup errors after installation

See here: http://grass.osgeo.org/wiki/WinGRASS_errors

Errata

see also OSGeo4W pkg-grass buglist

Some anti-virus software seem to think that the r.out.png.exe module (etc.) is a sneaky attempt to fool you into thinking it's an image instead of what it really is: a program which exports a PNG file. g.version is also reported to set them off. You'll have to bypass these over-zealous warnings as appropriate.
