I need to reproduce a bug that only appears on 32-bit machines. I don't own such a machine but I was hoping I could compile a 32-bit GHC on my Mac and debug using that. What changes do I need to make (e.g. to build/mk) to build a 32-bit GHC?

Install http://www.haskell.org/ghc/dist/7.0.3/ghc-7.0.3-i386-apple-darwin.tar.bz2 and make sure its ghc is first in your path.

Then build as normal.

Running the OS X installers is a bit intrusive. Is there a way to get a 32-bit version directly from source?

You need a 32-bit bootstrapping compiler as binary. The above binary-dist does not use the OS X installer (as it does not end in .pkg) Cheers Christian
