[Mapserver-users] GRASS raster

[Ling-Yen Liao]

Hi, I'm trying to find where the problem is.

$ /usr/local/bin/gdal-config --formats
finds grass;
$ ldd /usr/local/bin/libgdal.1.1.so
has a link to libgrass: libgrass5.so.0 => /usr/lib/libgrass5.so.0 (0x40300000);
also
$ gdalinfo soils
prints out something and looks like no problem;
but
$ /var/www/cgi-bin/shp2img -m soilsmap -o soils.png
outputs a BLANK img.

So anybody knows what's wrong?

Thank you!
