Haskell GTK on 64 bit MacOS X

gistfile1.md

Notes

• on lion (and snow leopard i suppose), make sure you are using a 64 bit install of ghc. Also, unless you are suggesting an edit to these directions, please go ask people on the relevant mailing list or wiki for help :)
• Tested on Mac OS X 10.7.4, GHC 7.4.1, 64bit Haskell Platform 2012.2.0.0 (installer package) with Command Line Tools for XCode (June 2012).
• These notes were originally brought to you by Carter Schonwald; the “I” probably refers to him. Eric Kow will refer to himself in the third person).

Steps

1. Install gtk and cairo via HomeBrew

   brew install glib cairo gtk gettext fontconfig
   brew deps gtk # see below
   brew deps gtk | xargs brew link
   brew link cairo gettext fontconfig
   gtk-demo # just to see what happens
   

   Brew may complain, who cares, this makes your life easier (at least if you're living in a haskell world :p )

   NOTE: you will need to make sure that all these Brew libs are built, and linked in

2. Download libfreetype

3. Unpack libfreetype, and then run

   brew install stow
   mkdir /usr/local/stow
   ./configure --prefix /usr/local/stow/freetype-2.4.8
   make
   make install
   cd /usr/local/stow
   stow freetype-2.4.8
   

   This will install the static and dynamic library files for lib freetype in /usr/local/ (../include and ../lib) , which is what you'll want, though this will contribute to brew doctor complaining, but again, this is the easiest way. Eric Kow has added stow to this mix because he thinks that making this easily reversible may be a good thing.

4. Install Haskell gtk

    cabal install gtk2hs-buildtools 
    cabal install gtk
   

   This should work sans complaints! Here if you run into problems installing cairo, you'll see it complains about pkg-config not finding the libpng package in it's search path. First make sure you see libpng.pc in /usr/X11/lib Then

    PKG_CONFIG_PATH=/usr/X11/lib
    export PKG_CONFIG_PATH
    cabal install cairo
    cabal install gtk
   

5. Install something using Cairo, eg, this plott.hs

    cabal install chart-gtk
    ghc --make plott.hs # see link above
    ./plott
   

   Try out some other cool libraries like diagrams!
