I have a function printErrors (as defined here http://dpwright.com/posts/2015/03/25/the-haskell-gl-package/#error-handling-utilities ) which I scatter around when things go wrong to try and find the root cause...


glGetErrors is in the openglraw package but not opengl, which is kind of weird.

on your web page: GL_NO_ERROR should be gl_NO_ERROR

and sadly, i put in the getErrors function and i'm getting the empty list right before it segfaults.
