Hi Brian, I'm trying to track down the wxHaskell in ghci bug on my Windows platform, and I'm running into an issue which is stopping me from getting anywhere before I even start.
The problem probably stems from the way wxHaskell is compiled under MinGW, which doesn't seem to behave quite as I would expect. Output for your minimal 'test'hs' program (per the post a couple of days back): C:\jodonoghue\haskell>ghci test.hs GHCi, version 6.10.4: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.

Loading package wxcore-0.12.1.2 ... <interactive>: stdc++: The specified module could not be found. can't load .so/.DLL for: stdc++ (addDLL: could not load DLL) I notice that in the wxcore Setup.hs build file, you manually append stdc++ to the list of libraries reported by wx-config. One consequence of this seems to be that ghci thinks it needs to load libstdc++, and this does not exist as a DLL on Windows. Actually, it is not needed as the wxWidgets DLL is statically linked with libstdc++ on Windows (I've run a dependency checker on the wxWidgets DLL, and it depends only on mingwm10.dll and the usual standard set of Microsoft system DLLs). I don't think wxcore actually depends on libstdc++. wxWidgets does (unless you explicitly compile without it) for sure, and I assume that on Linux you therefore need the libstdc++ to make everything link. Is this correct? I'm going to experiment with removing the libstdc++ dependency for Windows platforms, to see if this makes the problem go away. I'll keep you posted.
