Sorry I'm just learning haskell, so I don't get your suggestion. 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?

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.
