Ok, wait I think I misunderstood. You are saying that the ancient
ATI card in the autobuild machines might support the nvidia
extensions, and they are being properly detected. I thought you mean
whether the card was nvidia or not (neither are).
There are extensions to OpenGL which are vendor specific and some vendors may support ones that are not their own. In this case glDeleteProgramsNV has to do with vertex and fragment shaders and Nvidia had their own extension before it was approved by the review board for full GL status. I think that glDeleteProgramsNV could be removed since glDeleteProgramsARB covers the same functionality.
It seems to load from the command line with -nogui, I am testing now
whether I can load an object.
The ATI drivers should not define the NV extension in the headers if it is not supported by the driver. All GEM does is have an #ifdef for the presence of that extension and then builds with it enabled or not.
So, does the autobuild GEM run on the autobuild machine?
