Known configurations

Date	Arch	OS	GTK	GHC	Haskell Platform
2011-08	Intel 32 bit	Snow Leopard	2.24.5 HomeBrew	7.0.3	2011.2.0.1
2011-03	Intel 64 bit	Leopard	MacPorts	6.10

HomeBrew (last checked 2011-08)

brew update 
brew install gtk+ libglade
gtk-demo

If the gtk-demo appears to work, proceed to the rest of the ThreadScope install.

Troubleshooting

Problem: Bus error

Try running the gtk-demo program. Does it also fail?

If so, did you try updating your port? For example, if you are using Howebrew try:

brew update brew install gtk+

Then try gtk-demo again and finally

cabal install --renistall gtkhs

It may be worthwhile to try a gtkhs helloworld

The Quick-Guide for OS X 10.6, 64bit, MacPorts

Setbacks: old ghc (6.10.4 as of 2011-03-10)

Install MacPorts (macports.org)
Add +universal to /opt/local/etc/macports/variants.conf (not needed on 32bit)
execute: sudo port install ghc gtk2 gvfs cairo librsvg libglade2 gtkglext gtksourceview2 && sudo port install gtk2hs -universal

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

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 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/GLib.framework/Resources/dev/lib/pkgconfig:\ 
     /Library/Frameworks/Gtk.framework/Resources/dev/lib/pkgconfig ./configure --disable-gio

Build with

     make

Install (to /usr/local/ unless a --prefix option was passed to configure) 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 PKG_CONFIG_PATH.

-== 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.
