[wxhaskell-users] wxHaskell 0.90 symbols not found

[Henry L. <hen...@nt...>]

Hi
Having got wxWidgets 2.9.3 built and installed satisfactorily, 
in i86_64-only configuration on Mac OS Snow Leopard (10.6.8) with GHC 7.0.4 (64bit HP ver.)

- widgets HelloWorld apps, demos and samples are building and executing OK at least -

I now try to get wxHaskell working but get the following messages when trying to 
compile/link either the wxcore HelloWorld from  
https://raw.github.com/jodonoghue/wxHaskell/master/samples/wxcore/HelloWorld.hs
or the wx HelloWorld from 
https://github.com/kowey/debug-wx


Henrys-iMac:wxcore henrylockyer$ ghc HelloWorld.hs
[1 of 1] Compiling Main             ( HelloWorld.hs, HelloWorld.o )
