freeGlut and HopenGL on Windows

Does HopenGL support freeGlut? I would like to use some functions like "mainLoopEvent". If so, how should I install it?. I have tried renaming frreglut.dll to glut32.dll but it does'nt work. I am working with GHC 6.6 on Windowx XP. Any help would be appreciated.

 

Thanks

 

Pepe

Yes, the GLUT package supports all freeglut extensions to GLUT, and openSUSE
(the platform I'm developing on) ships freeglut as "the" GLUT for some time
now, so I'm quite confident that it works on *nices. I haven't tried it under
Windows yet, but I can't think of a fundamental reason why it shouldn't work
there, too. What did you do exactly and what happened?

Cheers,
   S.

I am sure that I am loading the right dll (it is in my workind directory,
and I have changed the mainLoop C function to print a message on the
console, and it does).
I was a bit confussed as function "glutVersion" was reporting "GLUT 3.7",
but that is because it is just guessing and getProcAddressInternal is not
working. To confirm this, I got a copy of Extension.hs and loaded it:

ghci -package GLUT -fffi Extensions.hs

then I get:

*Graphics.UI.GLUT.Extensions> getProcAddressInternal "glutSetOption"
0x00000000
*Graphics.UI.GLUT.Extensions> getProcAddressInternal
"glutSetWindowStayOnTop"
0x00000000

By the way, I get the same behaviour when using the original glut32.dll.

Any help?
