Gtk2Hs

Build Status

Gtk2Hs is a GUI library for Haskell based on GTK+. GTK+ is an extensive and mature multi-platform toolkit for creating graphical user interfaces.

For all new application development you should consider using haskell-gi as it has much more complete bindings. Cairo and WebKitGTK JavaScriptCore do not have GObject introspection data so you will still need to use the Gtk2Hs packages for those (even when using haskell-gi for everything else).

Installing C libraries

The following commands will install most of the C libraries used by the Gtk2Hs and haskell-gi.

Fedora

sudo dnf install gobject-introspection-devel webkitgtk3-devel webkitgtk4-devel gtksourceview3-devel

Ubuntu/Debian

sudo apt-get install libgirepository1.0-dev libwebkitgtk-3.0-dev libwebkit2gtk-4.0-dev libgtksourceview-3.0-dev

Arch Linux

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 libiconv. However 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.

Windows MSYS2

Install MSYS2 and Chocolatey. Then in a shell with administrator privileges:

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

(make sure ~/.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
