Great!

I would advise against using GLUT. I recommend GLFW-b. You can get it from Hackage. I've tested it on Windows 7, OSX, and Linux. It should just work out of the box.

You need to find a copy of glut32.dll and put it into the same directory. If you want to use GLUT, I would use the dll from freeglut. By the way, if you want to use ghci with opengl you will need to start ghci with -fno-ghci-sandbox. Otherwise you will get weird crashes. This applies to GLUT and GLFW-b equally.
Please help me. I tried 2 days to install this. Before that I tried to instal WXHaskell too, and i failed. Or recomand me an library that you use and there are some examples of code to figure out how to use it and is good for my purpose: Pong.
I would use GLFW-b. You can find some example code for haskell opengl here: https://github.com/dagit/nehe-tuts That version uses openglraw and glfw-b. If you want to use the non-raw version of the api look at this version in the history of the repo: https://github.com/dagit/nehe-tuts/tree/447f5471f3e7fe07b44dc5d2d87c4a95be35... I hope that helps, Jason
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

Hi Not sure if this will do the trick, but you might have _two copies_ of the package installed over the top of each other. You often have this problem if there is a local copy for a specific user and a global, system-wide copy. If I remember correctly, I think I used the command ghc-pkg unregister <package name> to de-register a package (You might need to type in the full version number of the package that you wish to de-register) You can use ghc-pkg list to see which packages are installed, first. I don't know the "correct" way to go about installing packages, but I always do a sudo cabal install --global <package name> That way I don't end up with local and global duplicates overlapping and cause me and ghc confusion. Hope that helps. Mark On 20/05/2012, at 1:23 AM, ai00rea wrote:

Hello,
This is actually *two different* packages, exposing the same module
(namespace).
GHC has a language extension which allows you to select the correct package:
{-# LANGUAGE PackageImports #-}
module MyModule where
import "glfw-b" Graphics.UI.GLFW
...
This specifies that you want the "GLFW-b" package (as opposed to the "GLFW"
package).
You can also hide/expose/delete packages using the ghc-pkg command line
tool:
ghc-pkg hide GLFW-0.5.0.1
ghc-pkg expose GLFW-0.5.0.1
I don't recall the remove command by heart (probably "remove" :)
Hope this helps,
Balazs
