/* What's in here?
|
|
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..
|
|
(There is much left to be done)
|
|
|
|
ghcAndLibraries = {
|
|
ghc68 = {
|
|
ghc = {
|
|
src = "The compiler source"
|
|
extra_src = "source of extra libraries"
|
|
version = "GHC version as string"
|
|
}
|
|
|
|
core_libs = [ libs distributed the ghc core (see libraries/core-packages ];
|
|
extra_libraries = [ libraries contained extra_src ];
|
|
};
|
|
|
|
ghc66 = {
|
|
roughly the same
|
|
};
