Hello -- I'm wondering whether anybody has had any luck getting the GL_ARB_debug_output extension working with AMD hardware/drivers. The extension never shows up in my GL extensions string. I understand that it's generally only supported when using a debug OpenGL context, and after spending hours digging and hacking through framework code, I've got that working (wglCreateContextAttribs() with the debug bit set, etc.). Even then, no GL_ARB_debug_output support, and wglGetProcAddress() on its functions always returns NULL. I've tried several different cards (3xxx-5xxx) and driver versions (10.x-11.6) with the same results everywhere. Has anybody else had any luck with this?
On the plus side, there's the GL_AMD_debug_output extension, which offers nearly-identical functionality with virtually no setup headache. On the other, it's obviously a single-platform solution, and I'd like to use the more portable extension if possible. Speaking of which, here's minor question #2: does anybody know anything about the GL_AMDX_debug_output extension? I can't seem to find it documented anywhere.
Thanks for any help!
