14 # Build a package with the stage-1 compiler, multiple ways. A typical
15 # libraries/foo/ghc.mk will look like this:
16 #
17 # $(eval $(call build-package,libraries/base,dist-install))
18 #
19 # The package metadata is generated from the .cabal file and placed in
20 # package-data.mk. It will look something like this:
21 #
22 # libraries/base_dist_MODULES = GHC.Base Data.Tuple ...
23 # libraries/base_dist_PACKAGE = base
24 # libraries/base_dist_VERSION = 4.0.0.0

26 # libraries/base_dist_C_SRCS = cbits/PrelIOUtils.c ...
