Re: GHCI Can't Find Module But GHC Can

...

I think the problem is that GHCi doesn't respect #ifdef conditional compilation.

I wasn't aware of any bugs in that area, can anyone provide some sample code? (and I'm surprised, because GHCi just runs cpp in the same way as GHC).

Ah, I think it is probably just a failure to use the -cpp option on the ghci commandline. The error message isn't terribly helpful in this regard, since it complains about being unable to find a module that wasn't wanted anyway. It might be more useful to complain that a cpp # directive was found? Regards, Malcolm
