Gtk2Hs is a GUI library for Haskell based on GTK+. GTK+ is an extensive and mature multi-platform toolkit for creating graphical user interfaces.

This can be done with something like...

sudo apt-get install libgtk2.0-dev libgtk-3-dev

For OS X you have at least three options (none of them perfect)

• http://www.gtk.org/download/macos.php (webkit not currently working)
• http://www.macports.org/ (requires that you use the macports GHC too)
• http://brew.sh/ (still uses X11)

TODO

Install the latest Cabal and cabal-meta (make sure cabal-meta winds up in your PATH)

cabal install Cabal cabal-meta

Clone the repo from github

git clone https://github.com/gtk2hs/gtk2hs
cd gtk2hs

Install gtk2hs-buildtools from the repo (make sure they also wind up in your PATH)

cabal install ./tools

If you want GTK+ 3 and no GTK+ 2 suport

cabal-meta install

or if you want both GTK+ 3 and GTK+ 2 support

./install-both.sh
