[Haskell-iPhone] Running hsc2hs

[Stephen Blackheath [to GHC-iPhone]]

David,

It's all coming back to me. It uses the standard hsc2hs, but it gets it 
to compile using the iphone simulator gcc (even if it's compiling for 
iphone). It turned out that the answers are close enough to the real 
iphone that it works.

When I was developing it, there were no link errors. You could compile 
with the iphone simulator gcc, and the resulting binary would just work. 
Perhaps this has changed.

You could try iphone-cabal -v install <package>. That ought to tell you 
what arguments it is passing to hsc2hs, and debug from there.
