==== Using MacPorts and Snow Leopard ====
+
* [[Gtk2Hs/Windows|Windows]]
 
+
* [[Gtk2Hs/Mac|Mac]]
This explains how to install Gtk2Hs-0.10.1 on Mac OS X 10.6 Snow Leopard, in combination with GTK+ from MacPorts.
+
* [[Gtk2Hs/Linux|Linux]]
 
+
* Install the [http://hackage.haskell.org/platform/ Haskell Platform] for Mac
+
* Download gtk2hs from [http://www.haskell.org/gtk2hs/ 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
+
:::make
+
:::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 [http://hackage.haskell.org/package/Chart/ 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 [http://passingcuriosity.com/2009/haskell-on-snow-leopard/ 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 [http://gtk-osx.sourceforge.net/ 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 [http://gtk-osx.sourceforge.net/ 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 [http://gtk-osx.sourceforge.net/ GTK+ OS X Framework] (this uses the standard Mac package installer).
+
# Install [http://pkg-config.freedesktop.org/ pkg-config], either by compiling it from source or via MacPorts.
+
# Download and unpack the Gtk2Hs tar ball from the [http://www.haskell.org/gtk2hs/download/ 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/GLib.framework/Resources/dev/lib/pkgconfig:\
+
      /Library/Frameworks/Gtk.framework/Resources/dev/lib/pkgconfig ./configure --disable-gio
+
# Build with
+
      make
+
# 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 [http://macports.org 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 [http://www.haskell.org/gtk2hs/downloads/ 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:
+
make
+
sudo make install
+
 
+
==== Recent experiences ====
+
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 [http://haskell.org/gtk2hs/development/#darcs 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 [http://haskell.org/gtk2hs/development/#darcs 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.
