Sven,

I got this working by *removing* GL from the line extra-libraries: GL in the *cabal file.

It seems to work with this change. Perhaps GL is needed for another build method?

Thank you for doing the hard work with OpenGL and OpenGLRaw, that lets us experiment with our ChalkBoard accelerator.

Hi Sven,

I get the following error when trying to include OpenGLRaw, as build out of the box.

$ cat Main.hs import Graphics.Rendering.OpenGL.Raw

main = print "Hello" $ ghc --make Main.hs [1 of 1] Compiling Main ( Main.hs, Main.o ) Linking Main ... ld: library not found for -lGL collect2: ld returned 1 exit status

*Any* ideas? I'm stuck. I've got a OSX 10.5. Are there any gotyas I should know about?

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... Cheers, S.
