[Mapserver-users] Raster geotiff turns background yellow

[randy james]

Hi

I'm not sure of which version of GD was compiled, i
did not specify when i ran configure. I have 2.0.1 and
1.8.4 installed. 

I'll try downloading the source of GD 2.0.11 and
reconfigure, and compile with it tommorrow.

I have GDAL 1.1.8 installed
