I have the following GLSL code:
#version 150 compatibility
#extension GL_EXT_gpu_shader4 : enable
uniform sampler1D tex;
vec4 theValue = texelFetch(tex, 0, 0);
When I try to use this shader, I get the following compile error:
error(#202) No matching overloaded function found texelFetch
I'm using an Evergreen card with the latest drivers (10.12).
I can't reproduce your problem on Cat10.12. Could you please double check it or provide the whole shader?
Sorry, it was one of my mistakes.
