Hi, I'm using GHC 6.4.1 and I've installed WxHaskell 0.9.4 from the batch file. When trying to run the examples in interactive mode I get the following error: *************** Loading package base-1.0 ... linking ... done. Compiling Main ( C:/Programmi/Tony/wxhaskell-0.9.4/samples/wxcore/He lloWorld.hs, interpreted ) C:/Programmi/Tony/wxhaskell-0.9.4/samples/wxcore/HelloWorld.hs:6:0: Failed to load interface for `Graphics.UI.WXCore': Bad interface file: C:\Programmi\Tony\wxhaskell-0.9.4\lib\imports/Graphi cs/UI/WXCore.hi mismatched interface file versions: expected 6041, found 6040 Failed, modules loaded: none. *************** Here the question: Is there some workaround to make WxHaskell running with my sistem (GHC 6.4.1) or I should downgrade to GHC 6.4?
