Re: OpengGL lockup using GHC 6.6 on Intel Mac

I can get this to work if I compile it with ghc, rather than try to run it with ghci or hugs. ghc --make Alpha3D.hs ./Alpha3D works fine with no hangs. Deborah On Dec 1, 2006, at 6:49 PM, Deborah Goldsmith wrote:

It fails on PowerPC too, using the standard PPC distribution.

This also fails in Hugs (crashes rather than hangs), so it looks like it's a problem with the GLUT binding on Mac OS X Intel rather than something specific to GHC. I'll see if I can find a PPC machine to try it on also.

I can reproduce this with ghc-6.6 built from source as well. I sampled ghc while it was stuck like this, and it looks like it's trying to open a GUI event loop (not surprising if it's opening a window). It looks like something about that is not working.

Unfortunately, the Intel binary distribution on the downloads page is missing some of the OpenGL C headers, and so won't work properly either.

Well, it doesn't lock the whole machine but loading Alpha3D.hs int GHCi and typing main causes a window to be displayed with no content and ghc 6.6 locked up, requiring a hard kill.

The Haskell versions of the NeHe tutorials work for me on x86_64 openSUSE 10.1 (GHC 6.6 and bleeding edge GHC from darcs repo, perhaps a few weeks old), so I guess that this is a Mac issue. Jason converted the tutorials on a G4, so I assume it is a problem with Mac + Intel. I don't have access to such a platform, so some help is needed. Do any of the examples from

http://darcs.haskell.org/packages/GLUT/examples/

work on your platform?

Cheers, S.
