14 # Build a package with the stage-1 compiler, multiple ways. A typical
15 # libraries/foo/ghc.mk will look like this:
17 # $(eval $(call build-package,libraries/base,dist-install))
19 # The package metadata is generated from the .cabal file and placed in
20 # package-data.mk. It will look something like this:
22 # libraries/base_dist_MODULES = GHC.Base Data.Tuple ...
23 # libraries/base_dist_PACKAGE = base
24 # libraries/base_dist_VERSION = 4.0.0.0
25 # libraries/base_dist_HC_OPTS = -package ghc-prim-0.1.0.0 -XRank2Types ...
26 # libraries/base_dist_C_SRCS = cbits/PrelIOUtils.c ...
27 # libraries/base_dist_S_SRCS = cbits/foo.S ...
28 # libraries/base_dist_CC_OPTS = -Iinclude ...
29 # libraries/base_dist_LD_OPTS = -package ghc-prim-0.1.0.0
