Re: Broken dependencies on cabal install haddock

Hey Duncan, Thanks for the fast reply / sorry about my slow one! The next instalment: dave@eliza:~$ ghc-pkg check package ghc-6.8.2 has missing dependencies: Cabal-1.2.3.0 Which is interesting, no? Dave, 2009/2/4 Duncan Coutts :

There is also a library package called ghc.

Which should be installed if you have the compiler. Hmm.

If the package is broken due to missing dependencies then cabal-install ignores it. It's on my TODO list to make it report more clearly the fact that it needed a package that is broken (ie instead of removing the broken packages from the set of installed packages, add a constraint not to use that version and when we get a constraint conflict with we can report a more helpful message).

Dave, you can confirm if the ghc package is broken by running ghc-pkg check.
