They are in charge of detecting # the current platform. # # A summary of the detection will be displayed, and the file `config.mk' # will be created in the current directory. # # - When invoked later, this Makefile will include the rules found in # `config.mk'. This sub-Makefile will define some system-specific # variables (like compiler, compilation flags, object suffix, etc.), then # include 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 setup distclean modules # The `space' variable is used to avoid trailing spaces in defining the # `T' variable later. # empty := space := $(empty) $(empty) ifndef CONFIG_MK CONFIG_MK := config.mk endif # If no configuration sub-makefile is present, or if `setup' is the target # to be built, run the auto-detection rules to figure out which # configuration rules file to use. # # Note that the configuration file is put in the current directory, which is # not necessarily $(TOP). # If `config.mk' is not present, set `check_platform'. # ifeq ($(wildcard $(CONFIG_MK)),) check_platform := 1 endif # If `setup' is one of the targets requested, set `check_platform'. # ifneq ($(findstring setup,$(MAKECMDGOALS)),) check_platform := 1 endif # Include the automatic host platform detection rules when we need to # check the platform. # ifdef check_platform # This is the first rule `make' sees. # all: setup ifdef USE_MODULES # If the module list $(MODULE_LIST) file is not present, generate it. # #modules: make_module_list setup endif include $(TOP)/builds/detect.mk ifdef USE_MODULES include $(TOP)/builds/modules.mk ifeq ($(wildcard $(MODULE_LIST)),) setup: make_module_list endif endif # This rule makes sense for Unix only to remove files created by a run # of the configure script which hasn't been successful (so that no # `config.mk' has been created).
