Hi Sven, After comparing the 'ghc-pkg describe' for GLUT 2.2.0.0 and GLUT 2.2.1.0, on my OSX 10.5, this works for me: if os(windows) && flag(UseNativeWindowsLibraries) cpp-options: "-DCALLCONV=stdcall" extra-libraries: glut32 cc-options: "-DUSE_GETPROCADDRESS" else cpp-options: "-DCALLCONV=ccall" cc-options: "-DUSE_DLSYM" if os(darwin) frameworks: GLUT else extra-libraries: glut So a) + b). Other combinations (i've just tried them) do not work. Also, USE_NSADDRESSOFSYMBOL seems deprecated (ld gives link warnings), but -USE_DLSYM works, so I've also changed this. Please let me know how this works out. Andy On Aug 16, 2009, at 10:25 AM, Sven Panne wrote:

[...] Is this generally the case for Mac OS X users? If yes, the extra-libraries line should be excluded in the Cabal file for this platform. Have others experienced the same problem? Reports would be nice, regardless if things work or not...
Just another idea from a different email: Perhaps "-framework OpenGL" is missing for Mac OS X? It would be nice to hear what the right fix is, I don't have access to any Macs...
Hmmm, no replies yet... So I'd like to The OpenGLRaw.cabal obviously needs some tweaks on Mac OS X, but it is not clear for me what to do. Should
a) the "extra-libraries: GL" line be removed for the "os(darwin)" case?
b) a "frameworks: OpenGL" line be added?
What is the right way to fix things? a) alone? b) alone? Or both a) and b)? Feedback would be highly appreciated, because I don't have access to Macs.
Cheers, S.

OK, I've committed the changes above to the GLUT package repository. Could you (or somebody else) post the corresponding sections of a working OpenGLRaw and GLURaw Cabal file for OS X, please? I guess that they should both use dlsym(), too, and both should contain a "framework: OpenGL" line instead of an extra- libraries: line on this platform, correct? Cheers, S.
