Mac OS X

GHC

Mac OS X 10.5 (Leopard)

To install GHC on Mac OS X 10.5 (Leopard), there are the following options:

• install the Haskell Platform
• 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

See also Haskell on Snow Leopard.

To uninstall ghc call:

sudo /Library/Frameworks/GHC.framework/Tools/Uninstaller

HUGS

• install MacPort's hugs98 package.

TextEdit is Mac's default text editor, a very basic editor that works fine for most uses, you must however be careful to put it into plain text mode using the Format menu.
