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

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?

I don't believe so; Info.plist is the externally visible interface details, but these libraries should be hidden inside the app bundle and not visible outside of it. When the runtime dynamic library loader is invoked in the context of a bundle, it uses a special token to find bundle-relative internal libraries (see @executable_path and friends in `man 1 dyld`). This is independent of Info.plist, except insofar as existence (not contents) of that plist is part of Apple's definition of bundle. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonadhttp://sinenomine.net ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
