Mac OS X

GHC

Mac OS X 10.5 (Leopard)

To install GHC on Mac OS X, there are the following options:

install the Haskell Platform
use the standalone installer
install MacPort's ghc package

Mac OS X 10.6 (Snow Leopard)

Mac OS X 10.6.x (Snow Leopard) is currently not well supported. The problem is that GHC generates 32bit code, but gcc on Snow Leopard defaults to 64bit code now.

The workaround is to tell gcc to accept 32bit code:

install the Haskell Platform
patch the following wrapper scripts to include the flags "-optc-m32 -opta-m32 -optl-m32":
- /usr/bin/ghc
- /usr/bin/ghci
- /usr/bin/runhaskell
- /usr/bin/runghc
- /usr/bin/hsc2hs

Note: MacPorts' ghc package is not yet supported on Mac OS X 10.6.x (Snow Leopard).

HUGS

install MacPort's hugs98 package.
