[mapserver-users] can't display TIFFs

[Pushkar Pradhan]

Check if your GDAL was compiled with TIFF support:
gdal-config --formats
gtiff should be there, if it's not then you have to install libtiffs on
your system or configure gdal to use the internal tiff support:
./configure  --with-libtiff=internal --with-geotiff=internal

> unless the raster layer is included in the mapfile.  If I comment out that
