MAC OS X support for arbtt

[Vincent Rasneur]

Hi Waldir,

Thanks for the kind words.

I've installed Homebrew, and deleted my old MacPorts packages in order to see if there are some differences.

With Homebrew, the only difference is that I have no linking error with libiconv, as Homebrew does not install this library and relies on the system one. And there are no cabal issues when I configure/build arbtt. By the way, the MAC OS X port does not add any new dependencies in the cabal file.

For the installation directory, with Homebrew or MacPorts, my binaries were installed in ~/Library/Haskell/bin, not ~/.cabal/bin (and I don't know why...).

For the bunch of warnings, I have seen these warnings too (mixing of tabs/spaces, deprecated functions, ...), but they seem easy to fix and are not located in my patches ;-)

I think the patches are going to be fully integrated upstream. There is a commit in the arbtt repo here: https://github.com/nomeata/darcs-mirror-arbtt/commit/b979d03b1650e210fd302567a3024ad0e3b9ae1a

But the src/Capture/OSX.hs and src/Graphics/OSX/Window.hs files are still missing. Maybe they will be added in a future commit?

Regards,

Vincent
