RE: GHCi Package problem?

(the `impossible' happened, GHC version 6.2): can't load package `fgl' Please report it as a compiler bug to glasgow-haskell-bugs@haskell.org, or http://sourceforge.net/projects/ghc/. This happened after I removed base from the package_deps entry (see below). You shouldn't remove 'base' from the dependencies! (we're being conservative in flagging it as a bug in GHC, in this case it's a bug in your package spec.) When base is included, ghci start fine: Loading package base ... linking ... done. Loading package fgl ... linking ... done. Prelude I can even access some values: Prelude Data.Graph.Inductive.version FGL - Functional Graph Library, February 2005 However, when I try others, I get errors: Prelude Data.Graph.Inductive.Example.clr486 GHCi runtime linker: fatal error: I found a duplicate definition for symbol _DataziGraphziInductiveziInternalziFiniteMap_Empty_closure whilst processing object file ./Data/Graph/Inductive/Internal/FiniteMap.o This could be caused by: * Loading two different object files which export the same symbol * Specifying the same object file twice on the GHCi command line * An incorrect `package.conf' entry, causing some object to be loaded twice. GHCi cannot safely continue in this situation. Exiting now. Sorry. I don't know what to do about this. Looks like GHCi is trying to load an object file for a module that is already present in the package. If Data.Graph.Inductive.Internal.FiniteMap is present in the fgl package, then you shouldn't also have it in the current directory, because GHC will get confused (I believe the upcoming 6.4 release will be better in this regard, though).
