is there, by chance, a file named Prelude.hs in the working directory? (the directory you are in when you type ghci?) - jeremy

Ah. Thanks! That was indeed the problem. Though I think ghci:s response could be a little bit more transparent. Josef

Hi,

It seems I've been able to mess up my ghc installation pretty badly. Here is what happens if I just try to invoke ghci from the prompt:

$ ghci GHCi, version 6.10.4: http://www.haskell.org/ghc/  :? for help Loading package ghc-prim ... linking ... done. Loading package integer ... linking ... done. Loading package base ... linking ... done. <command line>: module `Prelude' is not loaded $

I have no idea what I did to end up in this situation. What I've been doing lately is reinstalling some packages. I also have another ghc installed but it's at a completely different place in the file system. The only thing I can think of is if cabal managed to somehow confuse the two ghcs and wrote some data in the wrong place.

What I really would like to know is if there is a simple way to fix this without completely reinstalling ghc with all the libraries I have installed. Has anyone else experienced anything similar?

If this is a potential bug I'd be happy to provide any data that might help track it down.

Cheers,
