You're probably correct about the dependencies. I have never tried to compile wxHaskell against GHC 6.12.1

I'm waiting for Haskell Platform to be released to make the required changes since (working primarily on Windows) I just don't have time to create a complete GHC 6.12 installation with most of the HP libraries (some of which are a pain to get working on Windows).

wxHaskell will support GHC 6.12.x within a couple of days of release of a suitable Haskell Platform.

Beating a dead horse, but today I decided to see whether I could install wxHaskell, all it took was a few edits in some .cabal files and one in wxcore's Setup to make it all build with 6.12.1. Still, it's annoying because you have to unpack everything, edit and cabal install in the unpacked directories. Now since I did that, I could upload new verxions of wxdirect, wxcore and wx to hackage, so others could do a simple cabal install wx. But I would only do that if I get a go-ahead from somebody authorised (since Jeremy uploaded the previous versions, he'd be qualified, I think). Or I could send the edits to Jeremy and let him do the uploading, whatever is preferred.

I used to recommend Gtk2hs over wxHaskell for GUI development as there was always a version that worked on Windows with the latest GHC release. I think I might have to switch back to recommending C# for GUI development...

The latest revision of wxHaskell can be compiled relatively easy, so that wxHaskell can be used immediately for the latest version of GHC.

Exciting allegation, but it doesn't quite check out with GHC 6.12.1 + cabal 1.8.0.2 and cabal-install 0.8 (see below). I would expect this issue to be easily resolved by specifying "containers <= 0.3.*" in the "wxdirect" package, but cabal is misbehaving (for me) and stating wxdirect needs reinstalled with a supposedly newer version of containers, 0.2.0.1.
