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? cheers, claus
