New proposal on howto library dependencies could be handled.
Just install ghc68_wrapper which will install the required dependencies ghc (and libraries) itself. The list libraries given in the wrapper attribute set can be user tuned in the future ? An alternative would be creating something similar to the gcc/g++ include/ lib/ scheme which is could be used by ghc to find installed packages.. svn path=/nixpkgs/trunk/; revision=9581

Goal: really pure GHC. This means put every library into its each package.conf
|
||||
and add all together using GHC_PACKAGE_PATH
|
||||
|
||||
First I've tried separating the build of ghc from it's lib. It hase been to painful. I've failed.
|
||||
Now there is splitpackagedb.hs which just takes the installed package.conf
|
||||
and creates a new package db file for each contained package.
|
||||
|
||||
The final attribute set looks similar to this:
|
||||
ghc, core_libs and extra_libraries will then be used to build all the ohter packages availible on hackege..
