bit binaries from GHC for Snow Leopard?
I've recently upgraded my OS to Snow Leopard, which broke my GHC. I was able to fix it on one machine by adding flags for 32-bit compiles in /usr/bin/ghc (something like -optl -m32 -opta -m32 -optc -m32, gathered from here). Now I can't get it to produce 64-bit binaries for my other machine, which supports 64-bits. The 32-bit flags break, and removing them breaks as well. Any tips?
When I try to compile I get stuff like this:
/var/folders/az/az3Ef9shFZq6RajmTEBwu++++TI/-Tmp-//ghc8006_0/ghc8006_0.s:212:0:
32-bit absolute addressing is not supported for x86-64
/var/folders/az/az3Ef9shFZq6RajmTEBwu++++TI/-Tmp-//ghc8006_0/ghc8006_0.s:212:0:
cannot do signed 4 byte relocation
/var/folders/az/az3Ef9shFZq6RajmTEBwu++++TI/-Tmp-//ghc8006_0/ghc8006_0.s:215:0:
32-bit absolute addressing is not supported for x86-64

Thanks!
64 bit Snow Leopard installers for the Haskell Platform are available, as of 2011.
My understanding is that at the moment ghc cannot generate correct 64 bit binaries under Snow Leopard. This appears to be in part because of a bug in its 64 bit link generation and in part because of a change in the native toolchain. The workaround you mention simply tells it to generate a 32 bit target and thus won't be part of any actual solution to your problem.
