Re: [Haskell-cafe] Haskell School of Expression (graphics)

I think this is fixed in the gtk2hs source tree, have you tried building from the repo?

cabal install gtk2hs-buildtools darcs get --lazy http://code.haskell.org/gtk2hs/ cd gtk2hs chmod +x bootstrap.sh ./bootstrap.sh

Is this worth chasing down? I loaded the Haskell Platform, which I assume has some graphics capability (Cairo?). Maybe my time would be better spent getting familiar with that?

There's some sort of glitch with Gtk2hs (on which SOE depends) that causes it to not build with GHC 7.x (?) unless you hand-edit some of the files (!)
