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.
See you,
Barney.
