We use Makefile.depend (default value for # .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to # distinguish them from others. # # Each Makefile.depend file sets DEP_RELDIR to be the # the RELDIR (path relative to SRCTOP) for its directory, and # since each Makefile.depend file includes dirdeps.mk, this # processing is recursive and results in .MAKE.LEVEL 0 learning the # dependencies of the tree wrt the initial directory (_DEP_RELDIR). # # BUILD_AT_LEVEL0 # Indicates whether .MAKE.LEVEL 0 builds anything: # if "no" sub-makes are used to build everything, # if "yes" sub-makes are only used to build for other machines. # It is best to use "no", but this can require fixing some # makefiles to not do anything at .MAKE.LEVEL 0. # # TARGET_SPEC_VARS # The default value is just MACHINE, and for most environments # this is sufficient. The _DIRDEP_USE target actually sets # both MACHINE and TARGET_SPEC to the suffix of the current # target so that in the general case TARGET_SPEC can be ignored. # # If more than MACHINE is needed then sys.mk needs to decompose # TARGET_SPEC and set the relevant variables accordingly. # It is important that MACHINE be included in and actually be # the first member of TARGET_SPEC_VARS. This allows other # variables to be considered optional, and some of the treatment # below relies on MACHINE being the first entry. # Note: TARGET_SPEC cannot contain any '.'s so the target # triple used by compiler folk won't work (directly anyway). # # For example: # # # Always list MACHINE first, # # other variables might be optional. # TARGET_SPEC_VARS = MACHINE TARGET_OS # .if ${TARGET_SPEC:Uno:M*,*} != "" # _tspec := ${TARGET_SPEC:S/,/ /g} # MACHINE := ${_tspec:[1]} # TARGET_OS := ${_tspec:[2]} # # etc. # # We need to stop that TARGET_SPEC affecting any submakes # # and deal with MACHINE=${TARGET_SPEC} in the environment. # TARGET_SPEC = # # export but do not track # .export-env TARGET_SPEC # .export ${TARGET_SPEC_VARS} # .for v in ${TARGET_SPEC_VARS:O:u} # .if empty($v) # .undef $v # .endif # .endfor # .endif # # make sure we know what TARGET_SPEC is # # as we may need it to find Makefile.depend* # TARGET_SPEC = ${TARGET_SPEC_VARS:@v@${$v:U}@:ts,} # # touch this at your peril _DIRDEP_USE_LEVEL?= 0 .if ${.MAKE.LEVEL} == ${_DIRDEP_USE_LEVEL} # only the first instance is interested in all this # First off, we want to know what ${MACHINE} to build for. # This can be complicated if we are using a mixture of ${MACHINE} specific # and non-specific Makefile.depend* .if !target(_DIRDEP_USE) # do some setup we only need once _CURDIR ?= ${.CURDIR} _OBJDIR ?= ${.OBJDIR} now_utc = ${%s:L:gmtime} .if !defined(start_utc) start_utc := ${now_utc} .endif # make sure these are empty to start with _DEP_TARGET_SPEC = _DIRDEP_CHECKED = # If TARGET_SPEC_VARS is other than just MACHINE # it should be set by sys.mk or similar by now. # TARGET_SPEC must not contain any '.'s.
