I am currently running Mac OS 10.5.7, and I have install many Haskell files, compiled a bouncing ball example, fixed the enableGUI bug, tried an IDE, and have started installing graphics libraries. I am using Cabal in the terminal to install what I need, though whenever I try to install opengl or a package of opengl; it comes up with an error. Macintosh-2:opengl matthew$ sudo cabal install Resolving dependencies... Configuring OpenGLRaw-1.0.1.0... cabal: Missing dependency on a foreign library: * Missing C library: GL This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is. cabal: Error: some packages failed to install: GLURaw-1.0.0.0 depends on OpenGLRaw-1.0.1.0 which failed to install. OpenGL-2.3.0.0 depends on OpenGLRaw-1.0.1.0 which failed to install. OpenGLRaw-1.0.1.0 failed during the configure step. The exception was: exit: ExitFailure 1 Macintosh-2:opengl matthew$ It appears that I have zoned onto the bit that's causing all this mess, I'm missing a C library: GL. Unfortunately after googling a while I have found no answer. Am I doing something wrong? Is there another way? Could there be a fix? Thanks, -Matt

OpenGL is installed on MacOS X by default; it looks like the .cabal file is missing a -framework OpenGL flag or similar. Write an email to the package maintainer, listed on http://hackage.haskell.org/package/OpenGLRaw Regards, apfelmus -- http://apfelmus.nfshost.com
