This is very interesting. Getting this apparently simple proof of concept working is difficult for me. I've tried on Suse 10.2 and Windows XP. files I used on XP:
The recommended wxwindows 2.4.2 requires a wxhaskell dependent on ghc640. The problem is that arrows require base >=2.0 I could update Cabal to 1.1.7 using darcs etc. But I find no instructions on how to update the base-1.0 which comes with GHC 6.4.0. Even with instructions I think it requires a C compiler or more?
I use WinXP, GHC 6.6, and wxWidgets 2.4.2. I compiled wxWidgets and wxHaskell from sources. Conal 23:47, 20 February 2007 (UTC)
