| 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! |
It worked when I threw away all port stuff.
great!
Thanks for this walkthrough. Could you clarify what the brew link step is about (#3), and why we wouldn't just do the default HomeBrew thing. Is this something related to freetype? What's wrong with using the Apple freetype?
I'd love to be able to update the Haskell wiki Gtk2hs Mac install instructions taking your walkthrough into account.
the link step is just to symlink those packages into usr/local/bin and usr/local/lib etc, because some of them default to being "keg only"
the problem with the apple freetype lib (which I assume you mean the one that comes with x11? ) is that it only provides the dylib (.dylib) and not the static lib (.so), and ghc currently doesn't really do dynamic linking by default on OS X.
So those are really two orthogonal issues, but I hope that answers your questions.
I can elaborate further if you like.
Thanks for the explanations!
I'm still stuck on http://hackage.haskell.org/trac/gtk2hs/ticket/1241 it seems. Hmm!
did you make ; make install lib freetype?
you need to do that before building anything else....
I suspect thats related to the linking error I filed about 2 months ago for ghc, but have been to busy to try to come up with a reproducible minimal example of c code to replicate it
Any chance you could dig up a link to that ticket? Thanks :-)
(I had indeed built/installed freetype from src, only diff being that I put it in stow and stow'ed it to add the symlinks prior). Sorry for the late delayed response. I misread your question to think it was something I'd need some effort to figure out whether or not I'd done it.
ok, did you trash all the package which use gtk2hs and rebuild them?
also, once you do that, check if things run via ghci vs statically linked and compiled?
what happens when running the example programs?
@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.
http://hackage.haskell.org/trac/ghc/ticket/5816
is the link
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
johan: these directions are only indicated to work with mac homebrew and I can only help you if you in fact follow the directions as indicated exactly.
