1) Can you try using 2.6.0's libraries instead of 2.3.6's libraries (use /opt/X11 rather than /usr/X11)
I wish: eile% ./debug_glx/bin/eqPly.app/Contents/MacOS/eqPly --eq-config examples/configs/config.eqc dyld: Symbol not found: _gll_noop Referenced from: /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL Expected in: /opt/X11/lib//libGL.1.dylib in /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL
2) Can you provide the crash report (likely saved in ~/Library/Logs/DiagnosticReports)?
See attached file. IN the crash report the stack trace is truncated/corrupted by one frame. In the debugger I reach the glXCreateNewContext call as shown below.
My guess is that a bad config is being requested, but we certainly shouldn't crash inside glXCreateNewContext.
Neither should GLX 1.2 gets reported nor glXCreateContextWithConfigSGIX return 0 without any error. Any chance of these getting fixed? It's already difficult enough to code for GLX with extensions, and having to care about non-standard implementation behavior makes this even worse. FYI we are using GLEW/GLXEW for this. As a workaround we fall back to glXGetVisualFromFBConfigSGIX + glXCreateContext which seems to work. See <http://www.equalizergraphics.com/cgi-bin/viewvc.cgi/trunk/src/libs/client/glXWindow.cpp?view=markup&pathrev=5582> Cheers, Stefan.

Jeremy, all,
this is a followup to bug 466: http://xquartz.macosforge.org/trac/ticket/466
I tried the following to get my implementation working, details below:
1) Use glXCreateNewContext: crash 2) Use glXCreateContextWithConfigSGIX: return 0
I'm running 2.6.0 with the following libraries:

What's the proper way to get this working?
Cheers,
Stefan.
