| NOTE: on lion (and snow leopard i suppose), make sure you are using a 64 bit install of ghc. Also, unless you are suggesting an edit to these directions, please go ask people on the relevant mailing list or wiki for help :) | |
| NOTE: gtk2hs 0.12.2 won't build with ghc 7.4.1, but the current darcs repo for gtk2hs does build | |
| NOTE: on 7.4 there seems to be a problem when in ghci and drawing to a window, but not when rendering to pdf. I don't know why this is, but if you do, let me know. I'll update this as i have more info | |
| note that these directions probably can use some cleanup, but i'm choosing these steps so that rebuilding any haskell library doesn't require remembering ANYTHING :-) | |
| (tested on ghc 7.2.2, assumes you have standard developer things installed on mac, like x11 and stuff) | |
| 1) cabal install gtk2hs-buildtools #(this should work with any haskell platform install) | |
| 2) brew install cairo gtk gettext fontconfig | |
| 3) brew link cairo gettext fontconfig and all the other dependencies listed for brew's gtk formula | |
| this is best done with | |
| by hand running brew link for each of the items in `brew deps gtk` along with fontconfig and gettext. | |
| some of these will already linked, and some won't be, so this command makes it simpler | |
| # brew will complain, who cares, this makes your life easier (at least if you're living in a haskell world :p ) | |
| NOTE: you will need to make sure that all these Brew libs are built, and linked in | |
| 4) download libfreetype, heres a URL you can use http://sourceforge.net/projects/freetype/files/freetype2/2.4.8/freetype-2.4.8.tar.bz2/download?use_mirror=iweb | |
| 5) unpack libfreetype, and then run | |
| ./configure ; make ; make install | |
| this will install the static and dynamic library files for lib freetype in /usr/local/ (../include and ../lib) , which is what you'll want, though this will contribute to brew doctor complaining, but again, this is the easiest way | |
| 6) cabal install gtk | |
| this should work sans complaints! | |
| now you can eg | |
| cabal install chart-gtk | |
| and run | |
| this https://gist.github.com/1655252 example chart code either by building with ghc and running the executable | |
| or by running main in ghc, and | |
| or | |
| try out some other cool libraries like diagrams! |

I got a bit busy so i couldn't follow up on the ticket.
basically if the .dylib is available but the .so isn't, it seems that certain crazy crashing could happen, but I never concocted a simplified example to test this out in an easy to reproduce manner
Woo! I'm pretty thrilled to report that after starting over (brew remove packages, unstowing libfreetype), I now have a working gtk2hs/cairo. Thanks for posting this and for your patience.
I must simply have overlooked a step or something (I remember brew remove complaining that some packages I wanted to remove weren't actually installed).
In case it helps, I've formatted your instructions and made them a bit more copy-and-paste friendly (see my fork). Hopefully a bit more foolproof against people like me, who tend to have trouble following instructions :-) Will think about adding this to Haskell wiki too
congrats and kudos
The last time I looked I could not see how to get Quartz support, Gtk+ 3 and WebKitGTK+ working with brew. For that reason I have been using MacPorts.
After installing MacPorts, I add this to my /opt/local/etc/macports/variants.conf file:
+gcc48 -x11 +no_x11 +quartz +gtk3
Then I run something like:
sudo port install webkit-gtk3 gnome-themes-standard gtksourceview3 gtk-osx-application
Then I build a version of GHC that uses the MacPorts libiconv and gmp by configuring the ghc build like this:
./configure --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-gcc=gcc-mp-4.8 --with-cpp=gcc-mp=4.8 --prefix=$HOME/ghc-7.8.4
Then I make sure that version of GHC is in my PATH and run:
cabal install gtk2hs-buildtools
cabal install webkitgtk3-javascriptcore gtksourceview3 gtk3-mac-integration
@kowey, the linking error was that only one of the .so and .dylib version was available
also make sure that you're using the homebrew built version of all the libs.
