Hmm are you using LANGUAGE pragmas or is CPP added in the cabal file? It won't pick those up (but I'd like to do that!). Passing along flags to GHC is high on the list too :))
If you use the '{-# LANGUAGE CPP #-}' style I think it should work! Let me know... will test as soon as I'm back at the computer!

Hey there - it seems that when using halive the c preprocessor is erring at a (pretty common) macro in my program:

1 error generated. maybe I should be passing in some extra data on the command line? Or maybe CPP isn't supported yet? Compilation through stack is working, it's only halive that encounters the error.

@lukexi I'm using {-# LANGUAGE CPP -#}
at the top of my file. I'll try both.
Oop, just remembered to check this and it's working here!
{-# LANGUAGE CPP #-}
#if MIN_VERSION_base(4,8,0)
#define END 11
#else
#define END 12
#endif
main = print [1..END]

This is on HEAD - are you using that or the hackage version? (planning on a new release soon!)
I was using HEAD. I'll try to pull newest, recompile and check some time today :)
