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:

1. Download the OSGeo4W installer - ​32bit or ​64bit

2. Run the installer.

osgeo4w-setup -g -k -a x86_64 -q -P gdal proj geos fftw libjpeg liblas-devel libpng libpq libtiff libxdr pdcurses regex-devel sqlite3 zstd-devel zstd laszip2 python3-core python3-six

Note: on 32bit platform use -a x86

Install the MSYS2 directory structure

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

1. Download and install MSYS2.

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

pacman -S tar libintl make bison diffutils git dos2unix zip

3. Install MinGW-w64 toolchain:

• 32bit:

  pacman -S mingw-w64-i686-toolchain mingw-w64-i686-cairo mingw-w64-i686-xz mingw-w64-i686-lz4
  

• 64-bit:

  pacman -S mingw-w64-x86_64-toolchain mingw-w64-x86_64-cairo mingw-w64-x86_64-xz mingw-w64-x86_64-lz4
  

4. Add to C:\msys{32|64}\home\user\.bashrc

export LC_ALL=C

Optional dependecies

Part of packaging process is also producing VC libraries using dumpbin command which is part of ​Visual Studio framework. It's recommended to install Common Tools for Visual C++ (e.g. in Microsoft Visual Studio 14.0).

In this case, following lines in the source file mswindows/osgeo4w/mklibs.sh should look like:

PROGRAMFILES="/c/Program Files (x86)"
VSDIR="$PROGRAMFILES/Microsoft Visual Studio 14.0"
PATH="$VSDIR/Common7/IDE:$PATH"
PATH="$VSDIR/VC/bin:$PATH"
PATH="$VSDIR/Common7/Tools:$PATH"
PATH="$PATH:/c/OSGeo4W${OSGEO4W_POSTFIX}/bin"

In newer MS Visual Studio versions, Visual Studio Community can be installed instead.

In the case of newer MS Studio versions (e.g. 2017 on 64 bit platform), following lines in the source file mswindows/osgeo4w/mklibs.sh may look like:

PROGRAMFILES="/c/Program Files (x86)"
VSDIR="$PROGRAMFILES/Microsoft Visual Studio/2017/Community"
PATH="$VSDIR/Common7/IDE:$PATH"
PATH="$VSDIR/VC/Tools/MSVC/14.16.27023/bin/Hostx64/x64:$PATH"
PATH="$VSDIR/Common7/Tools:$PATH"
PATH="$PATH:/c/OSGeo4W${OSGEO4W_POSTFIX}/bin"

Compiling and Installing GRASS GIS

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

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

cd /usr/src
git clone https://github.com/OSGeo/grass grass_master

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

cd grass_master

# 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

3. 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-7.7.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 the OSGeo4W cmd console (assuming that we compiled GRASS 7.6):

c:\osgeo4w\bin\grass76svn.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

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

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

4. 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

1. Download the ​NSIS installer

2. Install to c:\DevTools

Install NSIS: Untgz Plugin

1. Download the ​NSIS Untgz Plugin

2. Copy untgz.dll to c:\DevTools\Plugins

Install NSIS: AccessControl Plugin

1. Download the ​NSIS AccessControl Plugin

2. Unzip to c:\DevTools\

Create the WinGRASS Installer

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

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

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.
