Created attachment 119919 [details] Simple test program showing a shader compilation error
The shaders generated seem to be a source of the trouble. The compiler dislikes the following part of the shader:
int bits = ...; const uint mask = 0xFFFFFFFFu >> (32 - bits);
It complains: "error: initializer of const variable `mask' must be a constant expression"
Attached is a simple test program to check for this error. Compile and link using "g++ const_init.cpp -lGL -lSDL2 -lGLEW"
You think that's bad? How about the 'offest' typo? :) You need to force GL4 in order to do the trace. Might want to also have a copy of r600g that enables ARB_gpu_shader5 (which will remove the need for those wrong overrides).
