Gtk2Hs is a GUI library for Haskell based on GTK+. GTK+ is an extensive and mature multi-platform toolkit for creating graphical user interfaces.
Installing C libraries
The following commands will install most of the C libraries used by the Gtk2Hs and haskell-gi.
sudo dnf install gobject-introspection-devel webkitgtk3-devel webkitgtk4-devel gtksourceview3-devel
sudo apt-get install libgirepository1.0-dev libwebkitgtk-3.0-dev libwebkit2gtk-4.0-dev libgtksourceview-3.0-dev
sudo pacman -S gobject-introspection gobject-introspection-runtime gtksourceview3 webkitgtk webkit2gtk
OS X MacPorts
sudo port install gobject-introspection webkit-gtk3 webkit2-gtk gtksourceview3 gtk-osx-application-gtk3 adwaita-icon-theme
You will also need to build a MacPorts compatible of GHC. First install GHC some other way then unpack the source for the GHC version you want to use and run:
sudo port install libxslt gmp ncurses libiconv llvm-3.5 libffi ./configure --prefix=$HOME/ghc-8.0.1 --with-iconv-includes=/opt/local/include --with-iconv-libraries=/opt/local/lib --with-gmp-includes=/opt/local/include --with-gmp-libraries=/opt/local/lib --with-system-libffi --with-ffi-includes=/opt/local/lib/libffi-3.2.1/include --with-ffi-libraries=/opt/local/lib --with-nm=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/nm-classic make make install
Then make sure the
$HOME/ghc-8.0.1/bin is in your $PATH.
OS X Homebrew
Unlike MacPorts you will not need a custom build of GHC for homebrew since it uses the system
some packaged (such as WebKitGTK) seem to be less well supported on Homebrew.
brew install gtk+3
And if you got an error about that pkg-config can not find libffi when installing haskell-gi or something like that, you need
to find out where your brew installed libffi, and add the pkg_config(e.g.
/usr/local/Cellar/libffi/3.0.13/lib/pkgconfig) directory to $PKG_CONFIG_PATH.
TIPS: If you installed GTK with homebrew, you do not need to install X11 on macOS. The one installed by brew was linked with GTK+'s Quartz backend, and you can use macOS's native display manager, keyboard, and pointing device.
choco install ghc pacman -S mingw64/mingw-w64-x86_64-pkg-config mingw64/mingw-w64-x86_64-gobject-introspection mingw64/mingw-w64-x86_64-gtksourceview3 mingw64/mingw-w64-x86_64-webkitgtk3
Install Extra Tools
cabal update cabal install alex happy cabal install haskell-gi
~/.cabal/bin is in PATH)
Building with stack
While you currently cannot have the tools automatically installed with
stack you should be able to install them
in the local stack. For instance here are the build instructions for building Leksah using stack:
git clone --recursive https://github.com/leksah/leksah.git cd leksah stack install alex happy stack install haskell-gi stack install gtk2hs-buildtools stack install
