Christian, did you compile this distribution on a G5 PowerPC?
Yes!
GMP is statically linked into this distribution, so if it's using any processor-specific instructions I could see that tripping up my G4. If you or someone else can confirm that this works on a G5, then we should probably just update the downloads page with that requirement.
Your example works for me. Maybe my libgmp.a in <prefix>/lib/ghc-6.8.3/ (that's used for linking) can be exchanged on a G4? My ghc-6.8.3 itself is linked against this very same libgmp.a (and seems to run).
OK, replacing that libgmp with a custom-built version fixed my standalone GCD.hs example. So that confirms the problem. Unfortunately, that doesn't fix it for me; my real issue is that ghc iself is getting the illegal instruction error, in the middle of compiling haddock-0.9. And since ghc is statically linked to libgmp, it can't use the replacement lib for itself. (Ironic, since statically linking gmp is supposed to make installation _easier_ :-) It's not a big problem for me, though; one of the ghc-6.8.2 distributions should work fine, and I can use them to build 6.8.3 myself. Now that we've confirmed it, can someone please update the 6.8.3 downloads page (Replacing "PowerPC" with "PowerPC G5", perhaps)? Thanks, -Judah
