Can you tell me what the parameters are for your OSMesaCreateContext()

I do not know. I'll do some digging into the VTK source and ask on the
VTK list.


You could also try setting GALLIUM_DRIVER=softpipe and see if the
softpipe driver works.



The test still fails, however it fails differently, instead of a black
image I get a strip of colored snow at the top of the output image...

How about I just show you?

The output (boring black image) of last night's VTK LoadOpenGLExtension
test which used llvmpipe is here :

http://open.cdash.org/testDetails.php?test=180871306&build=2844006

The output of:

$ env GALLIUM_DRIVER=softpipe \
   /home/kevin/kitware/VTK_OSMesa_Build/bin/vtkRenderingOpenGLCxxTests \
   "LoadOpenGLExtension" "-D" "/home/kevin/kitware/VTKData" \
   "-T" "/home/kevin/kitware/VTK_OSMesa_Build/Testing/Temporary" \
   "-V" "Baseline/Rendering/LoadOpenGLExtension.png"

is here :

Could I get a binary of one of your test programs?  Linux 64-bit?
