ANNOUNCE: HPong-0.1.2: A simple OpenGL Pong game based on GLFW
About two days ago the beta version of the Haskell Platform was released. Since it comes with an OpenGL library, it is now trivially easy to start making OpenGL programs with Haskell. To test this, I decided to make a simple Pong clone for two reasons: * To experiment with making an OpenGL game * I chose to use the GLFW instead of the GLUT library because GLUT doesn’t respond to closing a window with the close button very well. However, I could only find one piece of sample code for GLFW. Because of that, I decided to make a small game that others can use as a starting point for their own games. The controls are very simple: The up and down arrow keys move your paddle and Esc quits the game. This is my first upload to Hackage, so any comments or suggestions are welcome.
I don't know the exact reason but this should not fail since I have Debian packaged ghc 6.10.1 and OpenGL-2.2.1.1 on my system. I think this is because the filename of the OpenGL shared library is /usr/lib/libGL.so.1 rather than libGL.so. This is why we have two binary distributions for Linux because editline library has the same naming issues in Debian. So, this may be Debian packaging problem of OpenGL bindings. But the interesting thing is that I was able to work around this in Debian, by temporarily making a symbolic link libGL.so pointing to libGL.so.1 and it hpong built successfully. Once it builds, hpong still runs even if I delete the symbolic link libGL.so. So, there is also a possibility that what may be wrong is with the build system (cabal or ghc).

No. Do not manually create the symlink. It sounds like you don't have the -dev packages for OpenGL installed. You should install them and then you should be OK.
