Hi Heinrich, Thanks for helping out. Seems I’m really unlucky with cabal and wxHaskell... A 28/05/2012, às 12:57, Heinrich Apfelmus escreveu:

I had wxHaskell working but since I installed the gtk2hs, which updated some packages I’m having some trouble. I’ve installed wxWidgets and wxHaskell again following the instructions in it’s webpage.

I don't really know what's going on, but there seem to be two potential issues:
* Your wx package has version 0.90 while your wxc package has version 0.90.0.3. I recommend to use the latest patch level releases of all three: wx, wxcore and wxc.
When I try to install wx after updating cabal it is failing on version 0.90.0.1: miguelnegrao@Mac-Miguel:~$ cabal install wx Resolving dependencies... Configuring wx-0.90.0.1...

The exception was: ExitFailure 1 Does this mean that the package that was pushed to cabal has an actual error ? How do I "use the latest patch level releases” of the packages ?
* Your wxWidgets (wxmax) version is reported both as 2.8.12 and 2.9.3.1
right. But that is because the current stable version is 2.8.12 and to use the latest version in homebrew I have to use the switch --devel which will install 2.9.3.1. I followed the instructions here :http://www.haskell.org/haskellwiki/WxHaskell/MacOS_X best, Miguel
