I have 7.0.2 building from source, using a binary version of GHC 6.12.3, and the GCC 4.4 (gcc44 package from CentOS). GCC 4.1(gcc package) that ships with CentOS 5.5. gave me the "relocation error" already detailed at the bottom of http://hackage.haskell.org/trac/ghc/wiki/Building/Troubleshooting.

 It would be really neat to have CentOS supported out of the gate, rather than having to install a bootstrapping ghc, to then compile latest ghc, to finally compile latest haskell-platform. Does anyone know of a trusted third-party repo that packages ghc or even better, the haskell-platform for CentOS? I found (http://pkgs.org/centos-5-rhel-5/nogin-random-x86_64/) but I know nothing about who is packaging them.


cheers,

Now that you mention it, I did have to switch to a newer gcc for the
x86_64 build.  I ended up using 4.5.  That part is annoying;  I wasn't
able to coax the default 4.1.2+patches into generating correct
position-independent code either.
