I recently compiled Grass on a Sun Sparc 10 and ran into the following problem after attempting to run it for the first time: ..grass4.1/sun4/etc/GIS.sh g.gisenv: not found ..grass4.1/sun4/etc/GIS.sh g.gisenv: not found ..grass4.1/sun4/etc/GIS.sh LOCATION_NAME: parameter null or not set Can anyone help me with these problems? Thanks much. Jim
