They are in charge of detecting the # current platform. # # A summary of the detection is displayed, and the file `config.mk' is # created in the current directory. # # - When invoked later, this Makefile includes the rules found in # `config.mk'. This sub-Makefile defines some system-specific variables # (like compiler, compilation flags, object suffix, etc.), then includes # the rules found in `PROJECT/builds/PROJECT.mk', used to build the # library. # # See the comments in `builds/detect.mk' and `builds/PROJECT.mk' for more # details on host platform detection and library builds. .PHONY: all dist distclean modules setup # The `space' variable is used to avoid trailing spaces in defining the # `T' variable later. # empty := space := $(empty) $(empty) # The main configuration file, defining the `XXX_MODULES' variables.
