Hello,

Compiling the Haskell OpenGL/GLUT bindings on Windows is unfortunately very
complicated,
because they use some Unix tools. It is recommended to use the Haskell
Platform instead,
which as you noticed, has them included. If for some reasons you need to
compile them manually,
the primary trick is to install a (recent version!) of MinGW/MSys, which
provides the necessary
unixy tools.

I have more experience with GLUT than with GLFW, so I can add that GLUT
works pretty
robustly too (I use Windows and OSX), even though it clearly shows the age.
The only big
problem I remember is with the middle mouse buttons; and there is some
inconvenience
with the initialization, and lack of vsync support (which has to be hacked
in). However,
it provides a display callback, which as far as I remember, GLFW does not
(it only has
a big loop).

As Jason said, to use GLUT, you need to put glut32.dll at a place where
Windows finds it
(either at the same directory your executable is - recommended if you
distribute your app -,
or some Windows system directory).

Also, with GHCi there are some issues, so first try the compiled version.
I'm not up-to-date
regarding how to solve these issues.

OpenGL/GLUT is much simpler than wxHaskell. I had very bad experiences with
wxHaskell
(though I believe they were primarily caused by wx itself), but that was
some time ago, so it
is possible that it is better now.

Hope this helps,
Balazs
