Unhappy Unable to resolve glXQueryExtension

I am trying to run a GL app and get the error message

Unable to resolve function glXQueryExtension

I have installed the latest Nvidia drivers. Does anyone have any suggestions
as to where to go next.

I am using an Aopen card based on the FX5200 GPU.

What GL app? Is it dynamically linked? What's your ldd output?

The app is part of Altairs Engineerings Hyperworks and I think the prob is
that it is using the 32 bit lib in /usr/lib whereas the installer creates only
a 64bit lib. Based on the ldd output I will have other probs when I get
past the glx issue.

Is this a 32bit app? The NVIDIA OGL library currently does not support direct rendering of 32bit apps in 64bit linux. However, I would expect the Mesa libGL.so (which you're using) to have glXQueryExtension defined. This is probably a question for the Mesa team.

Would the libs from the IA32 distribution work?

Thought so. Had to ask. I assume this implies that to get accelerated support
the app must be recompiled to use the 64 bit libs.
