Mac OS X Strike Force
The following is a wiki page to centralize discussion of how to improve Haskell on Mac OS X. The name "strike force" comes from dons' post on reddit and the comments therein.
- 1 Goals

Take care of the Haskell Platform installer
The Haskell Platform OSX installer is looking for a new maintainer (contact Greg: "greg at gregorycollins net").
- who is willing to take over?
- collaborate effort or single effort?
- where to host?
- what are the most presing things on the todo list?
Make GUI-bindings easy to install
Neither wxHaskell nor Gtk2hs with native Gtk seems to be easy to install. What's the state of HQK and qtHaskell?
- We should provide at least one easy way to install one set of GUI bindings
qtHaskell with i386 ghc can be compiled with the following steps:
- Install Qt via MacPorts with the universal option set.
- Install Perl 5.12 via MacPorts.
- qmake will default to building x86_64 binaries, which does not work with 32-bit ghc. Modify /opt/local/libexec/qt4-mac/mkspecs/macx-g++/qmake.conf, adding the following lines:
QMAKE_CXXFLAGS = -arch i386 QMAKE_CFLAGS = -arch i386 QMAKE_LFLAGS = -arch i386
- You could also create your own spec (macx-g++-i386?), and modify build.pl in the qtHaskell top-level directory to use this spec.
- Build qtHaskell by executing the build script in the top-level directory.
Make GHC 64 bit

How Haskell is on OS X today
The simplest methods are currently:
- Binary GHC framework (/Library/Framework)
- Binary Haskell platform framework (/Library/Framework)
- MacPorts (/opt/local)
- Fink (/sw)
- Homebrew (symlinked into /usr/local ?)
ChrisKuklewicz 11:53, 6 September 2010 (UTC) I use MacPorts for the infrastructure and compile ghc against /opt/local but with --prefix=/opt/ghc-6.12.3 to keep it separate.
working in GHC HEAD, not in any released version.
Difficult libraries on OS X
Libraries needed for ghc
- iconv (older version in /usr is incompatible with new version from MacPorts)
- readline (faked in /usr, provided by framework or MacPorts)
- gmp (framework or MacPorts)
Libraries needed for other packages? gtk?
OS X code integration
Write Haskell in XCode?
Write ObjectiveC against GHC.Framework?
FFI for Objective C from Haskell?
A cabal2pkg that maintains proper dependency tracking?
Discussion forum for all this?
