I have a simple frag shader that is not compiling on OS X. It says it does not know 'fragColor', but that is built-in, isn't it? I use it in all my other frag shaders but this one is giving me this error. Anyone know why that might happen?
Frag Shader compile log:
ERROR: 0:9: Use of undeclared identifier 'fragColor'
Failed to compile frag shader:
fragColor = vec4(1.0);
