In general, try to find precompiled packages (i.e., RPMs for most Linuxes, .deb for Debian, Install packages for MS-Windows etc). Check the GRASS download site for software providers.

Compilation

The compilation order should be kept due to inter-dependencies between the packages. Please keep the order as seen below. GRASS compilation is explained in Compile and Install.

Installation

The install order should be kept due to inter-dependencies between the packages. Please keep the order or install all in a single step:

  1. PROJ4
  2. Optional: GEOS
  3. Optional: PostgreSQL, mySQL, unixODBC, SQLite (SQLite is needed for QGIS)
  4. GDAL/OGR without GRASS support
  5. GRASS 6
  6. GDAL/OGR-GRASS plugin - file: gdal-grass-1.3.1.1.tar.gz (or later) [1] NOTE: the plugin needs to see the GRASS libraries . The best way is to add a file 'grass6.conf' into the directory /etc/ld.so.conf.d (edit as root) which contains the path to the GRASS libraries; then run 'ldconfig'.
  7. QGIS with GRASS support

[1] New plugin version as of 19 Oct 2005, requires GDAL 1.3.1 or later

Troubleshooting

All stuff installed but QGIS doesn't see GRASS or r.out.gdal doesn't work?

  • Check if GDAL finds the plugin:
        gdal_translate --formats | grep -i grass
        GRASS (ro): GRASS Database Rasters (5.7+)
  • Check if the GRASS libs are found by the plugin. All libraries should be found (maybe you forgot to run 'ldconfig' if you didn't install from RPMs?):
        ldd /usr/lib/gdalplugins/gdal_GRASS.so
        ldd /usr/lib/gdalplugins/ogr_GRASS.so
  • Check if the GRASS plugins are in the right directory (check the 'Auto register' directory reported in the output):
        export CPL_DEBUG=on
        ogrinfo -summary $HOME/grassdata/spearfish60/PERMANENT/vector/roads/head

Further Instructions

If you are still having trouble, please also vist GRASS for Fedora Core 4 for more detailed GRASS and GDAL compilation and installation instructions developed by Isaac Ullah for Fedora Core 4.

There are good instructions on source code compiling here http://casoilresource.lawr.ucdavis.edu/drupal/node/123
