 == Installation Notes ==
-=== Windows 7 32 bit ===
-==== Install Haskell Platform and MingW ====
-* Install the [http://hackage.haskell.org/platform/windows.html Haskell Platform] for Windows.
-* Optional : Install [http://mingw.org MinGW] as per the instructions on their web site. Also install MSYS and mingw-make. A version of MinGW does come with Haskell Platform but excludes MSYS and 'make'.
-==== Install libxml ====
-* Download and unzip the latest libxml2 and libxml2-dev archives from [http://ftp.gnome.org/pub/GNOME/binaries/win32/dependencies/ Gnome].
-* To the PKG_CONFIG_PATH environment variable add the 'pkgconfig' directory in libxml2-dev.
-* To the INCLUDE environment variable add the paths to the 'include' directory in both libxml2 and libxml2-dev.
-==== Install the GTK bundle ====
+* [[Gtk2Hs/Windows|Windows]]
-* Download and install the [http://ftp.gnome.org/pub/GNOME/binaries/win32/glade3/3.6/glade3-3.6.7-with-GTK+.exe bundled GTK and Glade binary].
+* [[Gtk2Hs/Mac|Mac]]
-* To the PKG_CONFIG_PATH environment variable add the 'pkgconfig' directory. The default path should be "C:\Program Files\Gtk+\lib\pkgconfig".
+* [[Gtk2Hs/Linux|Linux]]
-* To the INCLUDE environment variable add the 'libglade-2.0' directory. The default path should be "C:\Program Files\Gtk+\include\libglade-2.0".
-==== Install the Haskell bindings ====
-* At the DOS prompt run 'cabal install gtk'. Make sure you have at least 1.5 GB RAM otherwise this compilation will die.
-* At the DOS prompt run 'cabal install glade'.
-==== Test the GTK install ====
-* In some appropriate temporary directory run 'cabal unpack gtk'. This downloads and unpacks the Haskell sources.
-** Run the demos (using mingw-make)
-*** If you installed MinGW then in the 'demo' directory, navigate into the 'hello' directory and run mingw32-make.exe. Now run the executable that was created.
-** Run the demos (manual compilation)
-*** In the 'demo' directory, navigate into the 'hello' directory and run 'ghc --make World.hs -o helloworld.exe'. Now run the executable that was created.
-==== Test the Glade install ====
-* In some appropriate temporary directory run 'cabal unpack glade'. This downloads and unpacks the Haskell sources.
-** Run the demos (using mingw-make)
-*** If you installed MinGW then in the 'demo' directory, navigate into the 'gladetest' directory and run mingw32-make.exe. Now run the executable that was created.
-** Run the demos (manual compilation)
-*** In the 'demo' directory, navigate into the 'gladetest' directory and run 'ghc --make GladeTest.hs -o gladetest.exe'. Now run the executable that was created.
-==== Common Errors ====
-* Glade.h is not found
-  gtk2hsC2hs.exe : glade/glade.h: File does not exist
-Probably instead of installing the GTK/Glade bundle you installed them seperately. The GTK/Glade bundle comes with the "include/libglade-2.0" containing a number of header files. For some reason this directory is not included in stand-alone GTK and Glade installers. Install the bundle and add this directory to the INCLUDE environment variable.
-* Cabal cannot find gtk2hsC2hs.
-  Please install gtk2hs-buildtools' first and check
-  that the installdirectory is in your PATH (e.g. HOME/.cabal/bin).
-  cabal: Error: some packages failed to install
-Somehow the path to the cabal bin directory has been lost. To the PATH environment variable re-add the cabal bin directory. The default path should be "%USERPROFILE%\AppData\Roaming\cabal\bin".
-* Spinner error with the 'notebook' demo
-Running the 'notebook' demo in the GTK install gives:
-    [1 of 1] Compiling Main             ( Notebook.hs, Notebook.o )
-    Notebook.hs:14:35:
-    Not in scope: type constructor or class `Spinner'
-    Notebook.hs:78:13: Not in scope: `spinnerNew'
-    Notebook.hs:101:2: Not in scope: `spinnerStart'
-    Notebook.hs:109:2: Not in scope: `spinnerStop'
-    mingw32-make: *** [notebook] Error 1
-This happens because this demo uses the new Spinner widget in GTK 2.22. Since this is not available in GTK 2.16 you get this error.
-=== Mac OS X ===
-==== 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 [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.

- **************************************************
-* 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.
