Re: [wxhaskell-users] Question about how to install WxHakell on Ubuntu and Win7
Regarding the Ubuntu setup, wxHaskell 0.90 requires wxWidgets 2.9, which are not packaged for Ubuntu as far as I know. You can try `cabal install wx-0.13.2.3` for a version of wxHaskell compatible with wxWidgets 2.8, or build wxWidgets 2.9 from source -- which will probably be harder.

Re: [wxhaskell-users] wxHaskell and forkIO or forkOS
If the only restriction here is that all the GUI updates should happen on the main OS thread, doesn't it mean that Haskell (green) threads spawned through forkIO are fine, because they execute on the same OS thread?

Re: [wxhaskell-users] preview: wx-config in Haskell
Good to see something moving in wxHaskell on Windows space. Some random remarks: - making wx cabal Setups dependent on this library instead of the command line wx-config sounds like a very good idea - one of the reasons it currently fails to work with official wxHaskell darcs tip might be its usage of --version flag in wxcore/Setup.hs, which I mentioned in a post to wxhaskell-devel a couple of weeks back Are you coming to CamHac in three weeks' time? I'd love to get wxHaskell tip to buildable state in my environment, looks like your help could be invaluable. In the mean time I'll see if I can build from your branch.

My wxhaskell branch at http://darcsden.com/kowey/wxhaskell contains a Haskell implementation of wx-config. It seems to work for me as a drop-in replacement for wx-config on Windows, at least as far as wxHaskell is concerned. Note that it offers none of the features of the real wx-config. Good news - - no need to set WXCFG - setting WXWIN is optional if you put wxWidgets in a path this wx-config will think to look at (eg. C:\wxWidgets-2.8) - can be used as a Haskell library - can be depended on as a Cabal dependency Bad news - has not been tested with wxWidgets 2.9 - broken with HEAD wxHaskell (seems to work for the latest released one) - no maintainer: I don't think I have the resources to actually maintain it or extend it with new features. I'm mainly hoping to break inertia by starting with something that sort of works while hoping that somebody else can take over. - none of the features/safety of the real wx-config. In fact, it's little more than a glorified putStrLn of the wx-config --cppflags --libs output.
