[Haskell-cafe] What's wrong with these foreign calls?

[Andrey Yankin]

For me it seems like calls to GLFW are normal but when I use indirectly GL
(through GLFW) I see a mess.
How could not they be connected properly?

Please, give me any hint...
I use Ubuntu 12.04 and The Glorious Glasgow Haskell Compilation System,
version 7.4.1
