/* We will check for errors later when we try to use the program */Lets not do that. Assuming you're talking about inside drawPrimitiveDrawStrided, that's going to kill performance. What is the problem with checking for errors right after compilation?
The error wasn't being generated from GL using checkGLcall() until I called glUseProgramObjectARB() (equivalent to glBindProgramARB()). If there is an error, we need to use glGetInfoLogARB() to get the detailed error message. Up until that point, none of the other functions (Source, Compile, Attach, Link) return any type of error from checkGLcall().
Yes, checkGLcall doesn't work for that. We should just check the info log.
