I can take any of these opengl applications or other examples on the web, but I can't get the application to run on Win32?
They will compile(except for the GLU ones) but when I launch them, the windows just closes? Is HOpenGL supported well on Win32?

I have ghc 6.6
John, I also have a Win32 box (I'm using Windows XP) and I wanted to try some OpenGL as well. I have news for you, good, bad, and ugly. First, the bad news: The HOpenGL site is outdated. Look at [1] and note the date of the most recent release: September 9, *2003*. [1] http://www.haskell.org/HOpenGL/releases.html Now, the good news: I believe the GHC 6.6.1 prepackaged Windows installer comes with OpenGL and GLUT libraries built in. The catch is that the GLUT library was compiled /without/ support for the FreeGLUT library. If standard OpenGL and standard GLUT meet your needs, then go for it. Lastly, the ugly news: If you need or want FreeGLUT, then you just need to compile FreeGLUT itself and then recompile the Haskell GLUT library. As an alternative to GLUT, you could also try GLFW. Be warned, though: I had to resort to major hackery (and a learning curve) to get either of these to work. First, I managed to hack GLFW into partially working. I took what I learned, applied it to FreeGLUT, and made some progress there. I went back and forth, hacking one library and then the other, accumulating what I had learned. In the end, I got FreeGLUT (both the C library and the Haskell bindings) to compile and I successfully installed them into GHC. I made one last hacking attempt with GLFW, but I was unable to successfully install it, and finally I gave up on it in favor of my newly working FreeGLUT installation. If you want to use FreeGLUT, just ask, and I will gladly post how I got it working. -- Ron
