I'm back in Cambridge now. Snowdonia was great, and just as wet as expected.
As far as I'm aware, nobody's got a fully functioning Snow Leopard GHC yet. Just before going away, I tried to use my partly-functioning 64-bit GHC to build 6.10, but found that the stage 1 compiler segfaulted.
My plan now is to get 6.8.3 fully working so that we all have something, if a little old, that works. (This is because I need it for another project.) Once I've managed this, I'll post a full set of instructions to get everyone else going too. Then I plan to attempt to get 6.12 working, and provide a binary that can be used for bootstrapping. (I may need some pointers for this.)
Incidentally, 6.12 doesn't appear to be in http://www.haskell.org/ghc/dist/ , only in the Darcs repo. Was that intentional?
So far, the sticking point has been getting the interactive linker to work. Snow Leopard has much tighter security than its predecessors, so we have to use mmap. Unfortunately, the mmap version of GHC's linker also requires mremap, which is a Linux-only extension that Snow Leopard doesn't have.
I believe we fixed the mremap dependency in 6.10, and that was also when we added support for libffi. I expect you'll have a much easier time getting GHCi to work with 6.10 or 6.12, so use 6.8.x for bootstrapping only. Cheers, Simon
