Re: [Haskell-cafe] Installing wxHaskel on Snow Leopard

Would it be necessary to change Info.plist? It would be nice being able to distribute haskell apps in general, not only wxHaskell apps. One can certainly write the UI in C++/Objective C, or what have you, and use FFI to call haskell libraries. But I am also interested in writing an app 100% in haskell. Has anyone done that?

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?

This sounds like cabal-macosx was not updated to handle dynamic GHC libraries. (GHC used to default to static; OS X was one of the first platforms to switch to default dynamic.) I know in theory how to deal with this (copy the necessary libraries into the app bundle and use install_name_tool to adjust the references to be bundle-relative) but could not give you exact details.
