Hello

Could it be done and would it be interesting, building 'ghc' using cabal?

 * 'lhc' does it  * Use 'cabal-rpm' and 'cabal2arch' to create packages for linux   distributions  * As ordinary user, install specific versions in your home   directory.   cabal install ghc => $HOME/.cabal/bin/ghc  * Get base packages as a dependency.

... except we then have a chicken and egg problem: GHC is built with Cabal, which needs a Haskell compiler/implementation, etc. ;-)

Well, GHC is already written in Haskell, so you already need GHC to compile GHC. I think the reasons are more to do with the fact that Cabal doesn't have some features that are needed for such a complex build as GHC, maybe including the bootstrapping that needs to happen. Alex
