Could you explain to me what exactly I have to do? According to this<http://cvs.haskell.org/Hugs/pages/libraries/OpenGL/Graphics-Rendering-OpenGL-GL-BasicTypes.html#t%3AGLfloat>page GLfloat is just a type synonym for type Float. How come the error message differentiates between them? 2009/9/28 Lyndon Maydwell <maydwell@gmail.com> I think this is an opengl version problem. I came across this error in
vacuum-opengl after I had upgraded my opengl. I patched it up using a "from<numeric type>" call.
