123,Haskell Platform 2010.1.0.0 platform does not include C++ support,jodonoghue,refold,"Unable to cabal install wx (wxHaskell installation) on 2010.1.0.0 Haskell Platform (this has succeeded on previous versions of HP).

Analysis showed error compiling the wrapper around C++ code in wxWidgets, due to cabal unable to find cc1plus.exe. 

This is blocking for anyone trying to compile C++ code via Cabal installers on Windows using the latest HP, and breaks wxHaskell installation on Windows using Haskell Platform.

Attached reply from Neil Mitchell to mail on haskell mailing list:
