GRASS (Geographic Resources Analysis Support System) is a free Geographic
Information System (GIS) used for geospatial data management and
analysis, image processing, graphics/maps production, spatial modeling,
and visualization. GRASS is an official project of the Open Source
Geospatial Foundation.
GRASS requires proj, gdal, numpy and wxPython.
The following optional dependencies may be enabled:
blas
lapack
ffmpeg
mysql
postgresql
sqlite
The options you require must be specified by setting the variable ENABLE
before running grass.SlackBuild, for example
ENABLE="sqlite,ffmpeg" ./grass.SlackBuild
If you need to make grass libraries available on the system
echo /opt/grass/lib >> /etc/ld.so.conf && ldconfig
