Fortunately, yes. Reinstalling base is impossible (at least with GHC, might be possible with other compilers), so it's good that cabal doesn't even try. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Really impossible to reinstall `base' using cabal?
Thanks, Daniel. So, do you have any advice for me, with regard to solving this issue: Implicit import declaration: Could not find module `Prelude': Perhaps you haven't installed the "dyn" libraries for package `base'? ? That is, how do I get the dynamic versions of the `base' package libraries installed, if not via a `cabal install'?

How did you get your ghc? If from your distro's package manager, you should be able to get the dyn- libs from that too. If downloaded from the ghc page or built from source, well, then they should already be there, if they aren't, something went wrong.

Debian (and in extension, Ubuntu) builds a ghc-dynamic package (http://packages.debian.org/sid/ghc-dynamic) on i386 and amd64, but does not build -dyn variants of the packaged libraries. So you base and everything that comes with ghc is covered, everything else (including stuff like mtl) is not.

But everything that doesn't come with ghc *can* be reinstalled (though one has to be careful, and it may be inconvenient), so you provide a good starting point. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
