Roman, thanks. I've managed to install wxHaskell. Someone has already patched it like just you said: https://github.com/wxHaskell/wxHaskell
The sample programs compile and work fine now. The only problem now is that I want to distribute a wxHaskell application on mac OS X. I tried using macosx-app and cabal-macosx (https://github.com/michaelt/cabal-macosx) to make an "app" file. It runs fine on my machine, but it fails to run on another computer. I get the following error: Dyld Error Message: Library not loaded: /Users/eduardo/.cabal/lib/wxc-0.90.1.0/ghc-7.6.3/libwxc.dylib. What would be the best way to redistribute wxHaskell apps? -- Eduardo Sato On Thursday, August 8, 2013 at 10:20 AM, Roman Cheplyaka wrote: > * Eduardo Sato <eduardo.s...@gmail.com (mailto:eduardo.s...@gmail.com)> > [2013-08-07 14:46:02-0300] > > Hello, guys.
