I'm using ghc 6.8.3 on a Mac PowerBook G4. Googling "OpenGL illegal instruction" produced an unending choice of horror stories.
What message am I not getting? Is there some crucial manual I'm not reading? Is there something which we should be being told on the relevant wiki page?
You need to find (or build) a G4-compatible ghc; the 6.8.3 build for Leopard (and Tiger?) was built for a G5, and the above is the result.
This sounds like bad news to me. I wonder how broken this G5 ghc is for a G4. Perhaps it should be labelled G5 rather than PowerPC in the large print. I'm quite scared about trying to build ghc: I worry that it may involve confronting large areas of my ignorance. I'm running Mac OS X 10.4.11 on a 1.5GHz PowerPC G4 PowerBook with 768MB of memory. I've got gcc 4.0.0. I'm using the 6.8.3 build whose entry on this page http://www.haskell.org/ghc/download_ghc_683.html reads ----- MacOS X (PowerPC) * ghc-6.8.3-powerpc-apple-darwin.tar.bz2 This is a binary distribution for Mac OS X 10.4 (Tiger) on PowerPC G5 machines, prepared by Christian Maeder. It needs libreadline. 5.2.dylib and libncurses.5.dylib under /opt/local/lib/. libgmp.a is statically linked in. ----- Now I'm wondering how badly I've shot myself in the foot. Alarmed Conor
