Installing gtk3 for Haskell (GHCJS)

Question

I'm trying to install GHCJS on Mac OSX (Yosemite). So far, I have updated Alex and Happy and installed gtk2hs-buildtools. Now when I run cabal install ghcjs-dom, I'm told that I need to install pkg-config...

~/Haskell/ghcjs-test/domTest: cabal install ghcjs-dom
Resolving dependencies...
Configuring cairo-0.13.1.1...
...

be found.

Hmmmm, pkg-config eh?

~/Haskell/ghcjs-test/domTest: cabal install pkg-config
cabal: There is no package named 'pkg-config'.

I then keep running cabal install ghcjs-dom, each time hitting a dependency that I then have to google and install via brew. This happens about 4 or 5 times. Finally, I'm stuck on gtk.

~/Haskell/ghcjs-test/domTest: cabal install ghcjs-dom

Configuring gtk3-0.14.2...
setup: The pkg-config package 'gtk+-3.0' is required but it could not be
found.
cabal: Error: some packages failed to install:
ghcjs-dom-0.2.3.1 depends on gtk3-0.14.2 which failed to install.
gtk3-0.14.2 failed during the configure step. The exception was:
ExitFailure 1
webkitgtk3-0.14.1.1 depends on gtk3-0.14.2 which failed to install.

After failing to brew install it, I try to install it with cabal:

Now I'm lost. Google is coming up short. Any ideas?

Answer 1

You need to brew install gtk+3. Doing cabal install gtk will only install the Haskell bindings for gtk. That said, the reason you are getting the build errors when trying to install gtk (which you don't need) is because you are missing the -fhave-quartz-gtk flag, which is needed for mac.
