[Haskell-cafe] Problem with wxHaskell

[John Velman]

Your code works fine on Linux.  :-)

Oh, by the way, I compiled my wxHaskell with GHC 6.2.2

I note that the windows binary on the download site was compiled with
GHC 6.2.1, and apparently these are not binary compatible with GHC 6.2.2.

Best,


John Velman
