--- Comment #7 from David Lonie <david.lonie at kitware.com> ---
I'm trying to get a trace, but apitrace is failing an assertion:

$ apitrace trace --api gl bin/vtkRenderingCoreCxxTests
"TestTranslucentLUTDepthPeeling"                                                

vtkRenderingCoreCxxTests:
/build/apitrace/src/apitrace-7.1/build/wrappers/glxtrace.cpp:97195: void (*
_wrapProcAddress(const GLubyte*, __GLXextFuncPtr))(): Assertion `procPtr !=
(__GLXextFuncPtr)&glXCreateContextAttribsARB' failed.

This is only happening on Mesa (I get a successful trace using my system nVidia
drivers), and it also happens when following the "Trace manually" instructions
here:

https://github.com/apitrace/apitrace/blob/master/docs/USAGE.markdown#tracing-manually

Is this issue familiar to anyone? I'll keep trying to get this working, but
would appreciate any tips if this is a known issue :)
