The Paths_foo.hs file is generated in a separate directory, something like dist/autogen/ (I can't remember exactly, you should be able to find it). To get GHCi to find it, you'll need to pass an appropriate -i <dir> flag.
a general question about cabal and ghci:
if I have successfully loaded my project files into ghci, I've presumably set all the right flags and paths, for ghci.
if I have successfully created a cabal project, I've presumably encoded all the right flags and paths, for cabal.
would it be possible to add a "cabal" command to ghci, so that we could:
- create a cabal file for the currently loaded project - load a project from a cabal file
or does this make no sense? doesn't visual haskell do something like that, using cabal behind the scenes?
Actually I did write the code for such a thing a while back, but never finished it off. There's a design choice; do you want - GHCi to understand .cabal files, or - Cabal to launch GHCi I concluded that the latter would be better, because then any hooks in your Setup.hs file still work, for example. I think this would make a nice bitesized task for someone who wants to do some Cabal hacking. Cheers, Simon
