Re: [wxhaskell-devel] CPP to FFI
Ah I see. I'm still looking through the wxHaskell code to see if there is any work I think I can do (as a beginner!) and thought id give this a mention. I agree that SWIG is a great tool! Hopefully they get their summer of code working.

[wxhaskell-devel] CPP to FFI
Hi guys, Did anyone see this new C++ foreign function generator mentioned in the haskell weekly news. http://ianwookim.org/fficxx/ At the moment the lack of documentation puts me off, but something like this could be the end of some of our generation problems. In my mind it's great that people are working on this sorta thing! I might look into this deeper at the weekend and see if I could use it to generate wx bindings.

Re: [wxhaskell-devel] Compile problems
I used this repo: https://github.com/atzedijkstra/wxHaskell Using wxWidgets 2.9.4, and GHC 7.6.3 the only change needed is in wxc/src/cpp/eljdc.cpp line 214 (the #if wxCHECK_VERSION(2,9,5) should be commented out - or at least had to be on my setup. Then a simple: cabal install ./wxdirect ./wxc ./wxcore ./wx Should hopefully get you up and running, let me know how it goes.

Re: [wxhaskell-devel] Build
I agree that the current deployment system for wxHaskell is not ideal and we should probably look into changing it. Does anyone have any ideas as to how we could go about this? The logical first step seems to be to combine the 3 packages (wxcore, wx, wxc) into some form of singly installed package. I'm a novice when it comes to cabal so not sure how what the effects of such a change could be. I appreciate that cabal is a great system for installing Haskell packages but perhaps we should provide additional install methods that also come pro-bundled with wxWidgets, this way we can control the version that we ship with - again the issue comes with how to install them on different platforms and in a controlled manner. These are just a few ideas. I'd be willing to work on additional deployment methods if anyone wants to take this on and needs help (as I say I'm possibly too novice at wxHaskell and Cabal to get this right on my own).

[wxhaskell-devel] Maintenance
Hi, It was mentioned on the Haskell beginners mailing list that wxHaskell was looking for volunteers. I was wondering if anyone knew of any "entry" level tasks which need performed so I can get a feel for the codebase etc. I have an intermediate knowledge of Haskell (less than a year but still learning). I also don't mind working in C/C++ which makes this project good fit in my mind. I realise there was a mailing list post a while ago debating the maintenance of wxHaskell but I couldn't figure out who the lead maintainer currently is?
