What's the easiest reference for how to build GHC head and get it up and running with cabal/haskell-platform?

I simply installed 6.12 + haskell-platform then built ghc-6.13.xx and rebuilt only the packages I needed with "cabal install --reinstall". Perhaps this is not the recommended way.

You have to rebuild _everything_ with the new version of GHC.

Indeed, something must be wrong because I can't build certain packages. (I have problems with "base" dependencies.)  For example:

$ cabal install QuickCheck Resolving dependencies... cabal: cannot configure QuickCheck-1.2.0.0. It requires base ==3.* For the dependency on base ==3.* there are these packages: base-3.0.3.1 and base-3.0.3.2. However none of them are available. base-3.0.3.1 was excluded because of the top level dependency base -any base-3.0.3.2 was excluded because of the top level dependency base -any

Looks like GHC-6.13 has dropped base-3 compatability; as such, QuickCheck-1.x will not build as there is no variant that works with base-4. Is there any particular reason why you're not using QuickCheck-2.y ? -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
