[HOpenGL] I now know why there's no binding to FTGL nor to GLTT

I wanted to make a binding to FTGL or GLTT, or the other one, I don't remember the name. Those all are for C++, not for C. Is there a way? I really don't know anything about calling C++ from C. Is there some way to make haskell bindings for a C++ library? Am I stuck in a dead end? Already? Vincenzo
