||
| − | ==== Changing Environment Variables ==== |
||
| − | This installation process involves adding/modifying environment variables. The rest of this subtopic shows you how to do that in Windows. |
||
| − | * Using the Environment Variable GUI |
||
| − | ** Click to the Windows symbol on the bottom-left where "Start" used to be |
||
| − | ** Right-Click on "Computer", choose "Properties" and click the link for "Advanced System Settings" |
||
| − | ** In the *top* window, Click "New" add a variable or click "Edit" to modify an existing one. |
||
| − | ** The variable should be a ';' seperated list of directories. |
||
| − | * At the DOS prompt |
||
| − | ** To see the current value of variable VAR: |
||
| − | > echo %VAR% |
||
| − | ** To modify variable VAR: |
||
| − | > set %VAR%=%VAR%;dir1;dir2 ... |
||
| − | ** To create variable VAR: |
||
| − | > set %VAR%=dir1;dir2.... |
||
| − | ==== 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 path to the 'include' directory from libxml2-dev. |
||
| − | |||
| − | ==== Install the GTK/Glade bundle ==== |
||
| − | * 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]. |
||
| − | * To the PKG_CONFIG_PATH environment variable add the 'pkgconfig' directory. The default path should be "C:\Program Files\Gtk+\lib\pkgconfig". |
||
| − | * 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 gtk2hs-buildtools'. |
||
| − | * 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. |
||
| − | * |
||
| − | * The following packages will be built: |
||
| − | * |
||
| − | * glib : yes |
||
| − | * gtk : yes |
||
| − | * glade : yes |
||
| − | * cairo : yes |

||
| − | * gnomevfs : yes |
||
| − | * gstreamer : yes |
||
| − | * documentation : yes |
||
| − | * |
||
| − | * Now do "(g)make" followed by "(g)make install" |
||
| − | ************************************************** |
||
| − | * Build and Install: |
||
| − | make |
||
| − | sudo make install |
||
| + | See [[Gtk2Hs/Installation]]. |
||
| − | ==== 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. |
