[[TOC]] = 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 environment === 1. Download the [http://download.osgeo.org/osgeo4w/v2/osgeo4w-setup.exe OSGeo4W installer] 2. Run the installer. {{{ osgeo4w-setup -g -k -a x86_64 -q -P proj-devel,gdal-devel,geos-devel,libtiff-devel,libpng-devel,pdal-devel,netcdf-devel,cairo-devel,fftw,freetype-devel,gdal-ecw,gdal-mrsid,liblas-devel,libxdr,libpq-devel,pdcurses,python3-matplotlib,python3-numpy,python3-ply,python3-pywin32,python3-six,python3-wxpython,regex-devel,wxwidgets-devel,zstd-devel,sqlite-dev }}} === Install the MSYS2 environment === 1. Download and install [https://msys2.github.io/ MSYS2]. 2. Start MSYS2 terminal and install requirements: {{{ pacman -S tar libintl make bison flex diffutils git dos2unix zip mingw-w64-x86_64-toolchain mingw-w64-x86_64-cairo mingw-w64-x86_64-fftw mingw-w64-x86_64-lapack mingw-w64-x86_64-pkg-config mingw-w64-x86_64-gcc mingw-w64-x86_64-ccache mingw-w64-x86_64-zlib mingw-w64-x86_64-libiconv mingw-w64-x86_64-bzip2 mingw-w64-x86_64-gettext mingw-w64-x86_64-libsystre mingw-w64-x86_64-libtre-git mingw-w64-x86_64-libwinpthread-git mingw-w64-x86_64-libpng mingw-w64-x86_64-pcre mingw-w64-x86_64-python3-six }}} 3. 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 [https://www.visualstudio.com Visual Studio] framework. It's recommended to install ''Common Tools for Visual C++''. == Compiling and Installing GRASS GIS == Start '''MSYS2''' terminal. 1. Download GRASS source code (see wiki:DownloadSource for details). Example for development version (main branch): {{{ cd /usr/src git clone https://github.com/OSGeo/grass grass }}} 2. Switch to GRASS GIS source code directory (in our case `grass`) and run `package.sh` compilation script: {{{ cd grass export OSGEO4W_ROOT_MSYS=/c/osgeo4w export VCPATH="C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx86\x64" # for release builds ./mswindows/osgeo4w/package.sh # for daily builds PACKAGE_POSTFIX=-daily ./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-8.x.dev}}}. === 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 [source:grass/trunk/mswindows 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 [source:grass-addons/tools/wingrass-packager scripts] used for [http://wingrass.fsv.cvut.cz 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 [wiki:HowToTestGrass6 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--Package}}}, e.g. {{{c:\temp\GRASS-70-Package}}}. === Install NSIS === 1. Download the [http://sourceforge.net/projects/nsis/files/NSIS%202/ NSIS installer] 2. Install to {{{c:\DevTools}}} === Install NSIS: Untgz Plugin === 1. Download the [https://nsis.sourceforge.io/UnTGZ_plug-in NSIS Untgz Plugin] 2. Copy {{{untgz.dll}}} to {{{c:\DevTools\Plugins}}} === Install NSIS: !AccessControl Plugin === 1. Download the [http://nsis.sourceforge.net/AccessControl_plug-in 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}}}. == Misc == === LibreDWG === Required by GRASS Addons [source:grass-addons/grass7/vector/v.in.redwg v.in.redwg]. 1. Download http://www.gnu.org/software/libredwg/ TODO: Finish this part. === WinGRASS 64bit Notes === External notes for building windows 64bit-binaries: * [http://lists.osgeo.org/pipermail/osgeo4w-dev/2013-August/002362.html OSGeo4W-64bit inital notes] * [http://trac.osgeo.org/grass/ticket/2095 GRASS changes for OSGeo4W 64bit] * [http://cran.r-project.org/doc/manuals/R-admin.html#Building-R-for-64_002dbit-Windows Building R for 64-bit Windows] * [http://www.gaia-gis.it/gaia-sins/mingw64_how_to.html Building SpatiaLite for 64-bit Windows] * [http://gvsigce.sourceforge.net/wiki/index.php/Setting_up_the_GNU_Compiler_Collection#Windows gvSIG and MinGW-w64 (C/C++ compiler)] * [http://download.osgeo.org/osgeo4w/x86_64/release/grass/grass-6.4.3-5-src.tar.bz2 recipe used to build GRASS 6.4.3 on OSGeo4W in 64bit] Tool chains for building windows 64bit-binaries: * [http://mingw-w64.sourceforge.net/ MinGW-w64 - GCC for both 64 & 32 bits Windows] * [http://tdm-gcc.tdragon.net/ TDM-GCC - A compiler suite for 32- and 64-bit Windows based on the GNU toolchain] * [http://www.drangon.org/mingw/ Native windows x64 software develop with Mingw-w64] == Hints == === Startup errors after installation === See here: http://grass.osgeo.org/wiki/WinGRASS_errors === 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 * Besides Cygwin and MinGW there is another along similar lines called "som" or "gow" or something? == Errata == * see also [http://trac.osgeo.org/osgeo4w/wiki/pkg-grass#Errata 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. == Open Tickets == '''winGRASS 6:''' [[TicketQuery(status=new|assigned|reopened&keywords~=wingrass&milestone=!7.0.0)]] '''winGRASS 7:''' [[TicketQuery(status=new|assigned|reopened&keywords~=wingrass&milestone=7.0.0)]]
