It currently works with Gtk+ 2.0 through to 2.8 on Unix, Win32 and MacOS X.
See [[Gtk2Hs/Installation#Supported_Versions]] for details on which systems should be able to build Gtk2Hs and which are known to be able to build Gtk2Hs.
The widget function coverage is almost complete, only a few minor bits and pieces are missing.
It currently builds with ghc 5.04.3 through to 6.8.2
(6.12.1 builds fine too, as of 15.4.10)

==== Using MacPorts and Snow Leopard ====
This explains how to install Gtk2Hs-0.10.1 on Mac OS X 10.6 Snow Leopard, in combination with GTK+ from MacPorts.
* Install the [ Haskell Platform] for Mac
* Download gtk2hs from [ gtk2hs website] and untar it.
* Install gtk, cairo, etc. from MacPorts like this (note that the +universal is needed; if you already installed gtk or one of its dependencies, it is recommended you reinstall those as detailed in the NB at the end of this section).
:::sudo port install gtk +universal
* go to the directory where gtk2hs is untarred and run
:::./configure --disable-split-objs --disable-gio
:::sudo make install
Alternatively, if you wish to follow the Mac OS X style of directory layout, you can use this configure command instead:
:::./configure --with-pkgconf=/Users/username/.ghc/i386-darwin-6.10.4/package.conf --prefix=/Users/username/Library/Haskell/packages/gtk2hs --disable-split-objs --disable-gio
Where username is your username ofcourse. Right now you should be able to run the demos. Unfortunately, to build any libraries depending on gtk2hs, such as [ Chart], you need to edit one more file. You will need to find "package.conf" for your ghc by doing
:::ghc-pkg list
In the output you will see the full directory to your package.conf file. In this file, you need to search for "gthread", and everywhere you can find it, add "/opt/local/lib" (with quotes) to the libraryDirs array before it.
If all went well, it should be properly installed now.
NB: If compiling fails with architecture errors for certain dynlibs, you need to reinstall the packages these dynlibs belong to with +universal by doing
:::sudo port upgrade packagename --enforce-variants +universal
Alternatively, and this is recommended, you can follow the steps on [ Haskell On Snow Leopard Blogpost] to immediately add the universal variant of each package:
# Edit /opt/local/macports/variants.conf and add +universal to the end of this file
# sudo port selfupdate
# sudo port sync
# sudo port upgrade --force-installed
==== Using the GTK+ OS X Framework ====
This explains how to install Gtk2Hs on Macs using the native [ GTK+ OS X Framework], a port of GTK+ to the Mac that does '''not''' depend on X11, and hence, is better integrated into the Mac desktop - i.e., menus actually appear in the menu bar, where they belong.  It also avoids the often tedious installation of GTK+ via MacPorts.  However, it misses support for optional Gtk2Hs packages that are currently not supported by the [ GTK+ OS X Framework], most notably support for Glade.  It does include support for Cairo, though.
Here is how to install the library:
# Download and install [ GTK+ OS X Framework] (this uses the standard Mac package installer).
# Install [ pkg-config], either by compiling it from source or via MacPorts.
# Download and unpack the Gtk2Hs tar ball from the [ Gtk2Hs download page] (I tested 0.10.0).
# Configure with (you may want to remove the two backslashes and put everything on one line)
      env PKG_CONFIG_PATH=/Library/Frameworks/Cairo.framework/Resources/dev/lib/pkgconfig:\
      /Library/Frameworks/Gtk.framework/Resources/dev/lib/pkgconfig ./configure --disable-gio
# Build with
# Install (to <tt>/usr/local/</tt> unless a <tt>--prefix</tt> option was passed to <tt>configure</tt>) with
      sudo make install
The library is now registered with the package database of the GHC you used for compiling.
NB: Thanks to Ross Mellgren for his post on the gtk2hs-users list that outlined the use of <tt>PKG_CONFIG_PATH</tt>.
==== Article as of Mid 2008 ====
Installing Gtk2Hs on Mac requires some finesse, at least until Haskell Libary Platform is built or ghc-6.8.3 is
available in macports. (These are planned for late 2008.)
* Install [ MacPorts]
* Install dependencies:
sudo port install glade3 libglade2 gstreamer gst-plugins-base gtksourceview cairo librsvg gtkglext firefox
* Update PKG_CONFIG_PATH (for libraries)
export PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/opt/local/lib/pkgconfig
* Update ghc to use macports libs: Edit your main <tt>ghc</tt> driver program and change the last line to:
exec $GHCBIN $TOPDIROPT ${1+"$@"} -L/opt/local/lib -I/opt/local/include
* Download Gtk2Hs following instructions at [ Gtk2Hs Download page]
* Check configuration:
./configure --enable-docs --enable-profiling
* Configuration completed successfully.         
* The following packages will be built:         
* glib          : yes                           
* gtk          : yes                           
* glade        : yes             
* cairo        : yes               
* svgcairo      : yes             
* gtkglext      : yes             
* gconf        : yes               
* sourceview    : yes           
* mozembed      : yes             
* soegtk        : yes                           
* gnomevfs      : yes             
* gstreamer    : yes           
* documentation : yes                   
* Now do "(g)make" followed by "(g)make install"
* Build and Install:
sudo make install
==== Recent experiences ====
See [[Gtk2Hs/Installation]].
I successfully installed the latest version on Mac OS 10.5 by:
* Installing Macports.
* <tt>sudo port install ghc</tt>
* <tt>sudo port install gtk2hs</tt> - which does not complete successfully. It does however, install the appropriate dependencies. Note that there are so many, you may need to install a couple of times due to time outs etc.. The build of Gtk2HS will fail, but that is ok - continue as below. Also note that ghc configure will give up if your perl5.8 is not new enough, if so deactivate it and try again.
* Remove the build directory under <tt>/opt/.../build/gtk2hs</tt>
* Download Gtk2Hs via darcs as per [ the gtk2hs download instructions]
* do a <tt>sudo port install automake</tt>
* do a <tt>sudo port install alex</tt>
* do a <tt>sudo port install happy</tt> (Note this also fails and must be built from source. See the [[Happy]] page for details.)
* Follow the build instructions on the [ the gtk2hs download page]. I would suggest using <tt>./configure --prefix=/opt/local</tt> to get it in the same place as ports - personal preference though.
Good luck - as usual, your mileage may vary.

[edit] 1 What is it?

Gtk2Hs is a Haskell binding to Gtk+ 2.x. Using it, one can write Gtk+ based applications with GHC.
