To compile GHC as a package, get a recent GHC source tree and set 'BuildPackageGHC=YES' in your mk/build.mk. You should also set $(GHC_PKG) to point to your ghc-pkg command. Then build ghc as normal, and in ghc/compiler say 'make install-inplace-pkg' to register the package (this won't do any actual installation, just register the package with your installed GHC).
I have ghc-6.2.2 installed on my system and it could not build ghc if I set BuildPackageGHC=YES. It failed with WARNING: error while reading directory gnore-package ghc-6.2.2: file `ghc' does not exist so I guess it didn't understand the parameters "-ignore-package ghc". If I download a recent snapshot of ghc-6.4, compile it, set BuildPackageGHC=YES, how can I compile the package using that compiler? And will that package be compatible with my installation of ghc-6.2.2? Thanks in advance, Lennart
