An overview of the dependencies required for building with MingW

We would like use a simplified approach with pre-built libraries for all the GRASS dependencies but for the moment compiling many of the dependencies is required in order to have the proper files for grass. Still, a few steps are eliminated if compilation is done within the OSGeo4W directory structure.

Install the OSGeo4W directory structure

OSGeo4W has several of the required dependencies for compiling GRASS:

1. Download the OSGeo4W installer from ​here.

2. Run the installer.

3. Select Advanced Install, and Next.

4. 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 (?))

5. Select grass from the desktop section (this is a binary but we'll compile from source later).

6. Also select:
   • avce00
   • fftw-devel
   • freetype-devel
   • freetype-devel-mingw
   • gpsbabel
   • gsl-libs
   • gsl-devel
   • libxdr
   • msys
   • pdcurses-devel
   • tcltk-devel
   • mingw-libs (contains mingw-style libraries for VC build binaries and depends on gdal, libpq, libjpeg-devel, sqlite3, libtiff, zlib, proj)

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

Install the environment for compilation (MingW)

1. Run msys (there should be an icon on the desktop)

2. type:

    mkdir /c/osgeo4w/apps/msys/osgeo4w
   

3. Copy c:\osgeo4w\apps\msys\etc\fstab.sample to c:\osgeo4w\apps\msys\etc\fstab (without .sample)

4. Open c:\osgeo4w\apps\msys\etc\fstab

5. At line 16, change:

   c:/mingw		/mingw
   c:/ActiveState/perl	/perl
   

To:

c:/osgeo4w/	/osgeo4w

6. Download the MinGW packages:
   • mingw-runtime from ​here
   • mingw32-make from ​here
   • gcc-core from ​here
   • gcc-g++ from ​here
   • w32api from ​here
   • mingw-utils from ​here
   • bin-utils from ​here

7. Unpack all to c:\osgeo4w

Pre-built Binaries

Download:

• flex from ​here
• bison from ​here
• bison-deps from ​here
• regex from ​here
• gettext-bin from ​here
• gettext-lib from ​here
• libintl-bin from ​here
• libintl-lib from ​here

Unpack all to c:\osgeo4w

Compiling and Installing GRASS (6.4.0)

Without a fix for gdal, there will be several errors... help please

1. Download the latest GRASS 6.4.0 source code from ​here.

2. Unpack to c:\osgeo4w\usr\src

3. 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 \

5. 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):

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.

Now GRASS should be installed in c:\osgeo4w\apps\grass-6.4.0\

Usage

The startup grass64.bat file should be in C:\OSGeo4W\apps\grass\bin Open it and replace the contents with:

@echo off
SET OSGEO4W_ROOT=C:\OSGeo4W
PATH %OSGEO4W_ROOT%\bin;%PATH%
for %%f in ("%OSGEO4W_ROOT%"\etc\ini\*.bat) do call "%%f"

rem #########################################################################
rem #
rem #		GRASS Initialization
rem #
rem #########################################################################

set WINGISBASE=%OSGEO4W_ROOT%/apps/grass/grass-6.4xxx (change to the appropriate grass version)
"%WINGISBASE%"\etc\init.bat %*

If you want to be able to use the console from within grass, you'll need a different startup file: Create C:\OSGeo4W\apps\grass\bin\grass64 with the following contents:

#! /bin/sh
