    attempting to use module `System.IO' (System/IO.hs) which is not loaded

ghc-6.8.2: panic! (the 'impossible' happened)
  (GHC version 6.8.2 for i386-unknown-linux):

Please report this as a GHC bug:

I am using Ubuntu 8.10 Linux 2.6.27-11-generic i686.

I am having trouble using cabal-install, and my real problem may lie there, but I thought I should report this anyway.

  • Keywords base base- panic panic! removed

When cabal-install says a package cannot be installed because it needs base 4, that does not mean you should install base 4. It means you cannot use that version of that package with ghc-6.8. You either have to use an older version of the same package, avoid using the package or upgrade to ghc-6.10 which comes with base 4.

For exactly this reason, cabal-install does not decide to install base 4 (which is why you had to go to such lengths to try to install it).

  • difficulty set to Unknown
  • Resolution set to wontfix
  • Status changed from new to closed

The error message is no longer a panic in 6.10.1:

$ runhaskell Setup.hs configure
<command line>: module `Prelude' is not loaded

Though perhaps it's equally obscure. We don't plan to support this anyway.
