Comment (by 246tnt@…):

 * The OpenGL errors are normal on OSX and those are not fatal. As the
 message says, the compilation fails but it will use a fallback method.
 (which in what's currently used shouldn't make much of a difference
 visually).

 This error happens because I rely on the GLSL 1.5 compatibility profile
 for those shaders. I basically want to use some of the advanced GLSL
 features not available in previous versions, but I don't want to give up
 the legacy pipeline. To go to full 3.x core profile, I'd need to
 completely give up immediate mode, use my own vertex shaders, re-implement
 the matrix stuff myself, etc, etc ... which I'm really not willing to do
 so I can just draw a few lines and 2 textured quads with pixel shaders
 applied ...


 * The CL error is the real issue. It says it selected "Intel(R) Core(TM)
 i7-2620M CPU @ 2.70GHz" which is a CPU implemention of OpenCL since your
 GPU doesn't do OpenCL. Now, that means it evaluated the device and thought
 that it was capable of running fosphor. But obviously it wasn't because
 even though the initialization went nicely, when it tried to actually
 queue the execution of some compuation, it failed with
 CL_INVALID_WORK_GROUP_SIZE. To know if this is justified, it would be
 useful to see the actual capabilities of the device. I attached a clInfo.c
 test program that should print all the required info. If you could compile
 and execute it and post the results, it would be nice.

 PS: Also, btw, I now _hate_ trac ... the damn 'attach file' function
 doensn't warn you it will just drop the whole comment you already typed
 ...
