We use Makefile.depend (default value for 56# .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to 57# distinguish them from others. 58# 59# Each Makefile.depend file sets DEP_RELDIR to be the 60# the RELDIR (path relative to SRCTOP) for its directory, and 61# since each Makefile.depend file includes dirdeps.mk, this 62# processing is recursive and results in .MAKE.LEVEL 0 learning the 63# dependencies of the tree wrt the initial directory (_DEP_RELDIR). 64# 65# BUILD_AT_LEVEL0 66# Indicates whether .MAKE.LEVEL 0 builds anything: 67# if "no" sub-makes are used to build everything, 68# if "yes" sub-makes are only used to build for other machines. 69# It is best to use "no", but this can require fixing some 70# makefiles to not do anything at .MAKE.LEVEL 0. 71# 72# TARGET_SPEC_VARS 73# The default value is just MACHINE, and for most environments 74# this is sufficient. The _DIRDEP_USE target actually sets 75# both MACHINE and TARGET_SPEC to the suffix of the current 76# target so that in the general case TARGET_SPEC can be ignored. 77# 78# If more than MACHINE is needed then sys.mk needs to decompose 79# TARGET_SPEC and set the relevant variables accordingly. 80# It is important that MACHINE be included in and actually be 81# the first member of TARGET_SPEC_VARS. This allows other 82# variables to be considered optional, and some of the treatment 83# below relies on MACHINE being the first entry. 84# Note: TARGET_SPEC cannot contain any '.'s so the target 85# triple used by compiler folk won't work (directly anyway). 86# 87# For example: 88# 89# # Always list MACHINE first, 90# # other variables might be optional. 91# TARGET_SPEC_VARS = MACHINE TARGET_OS 92# .if ${TARGET_SPEC:Uno:M*,*} != "" 93# _tspec := ${TARGET_SPEC:S/,/ /g} 94# MACHINE := ${_tspec:[1]} 95# TARGET_OS := ${_tspec:[2]} 96# # etc. 97# # We need to stop that TARGET_SPEC affecting any submakes 98# # and deal with MACHINE=${TARGET_SPEC} in the environment. 99# TARGET_SPEC = 100# # export but do not track 101# .export-env TARGET_SPEC 102# .export ${TARGET_SPEC_VARS} 103# .for v in ${TARGET_SPEC_VARS:O:u} 104# .if empty($v) 105# .undef $v 106# .endif 107# .endfor 108# .endif 109# # make sure we know what TARGET_SPEC is 110# # as we may need it to find Makefile.depend* 111# TARGET_SPEC = ${TARGET_SPEC_VARS:@v@${$v:U}@:ts,} 112# 113 114.if ${.MAKE.LEVEL} == 0 115# only the first instance is interested in all this 116 117# First off, we want to know what ${MACHINE} to build for. 118# This can be complicated if we are using a mixture of ${MACHINE} specific 119# and non-specific Makefile.depend* 120 121.if !target(_DIRDEP_USE) 122# do some setup we only need once 123_CURDIR ?= ${.CURDIR} 124 125# make sure these are empty to start with 126_DEP_TARGET_SPEC = 127_DIRDEP_CHECKED = 128 129# If TARGET_SPEC_VARS is other than just MACHINE 130# it should be set by sys.mk or similar by now. 131# TARGET_SPEC must not contain any '.'s. 132TARGET_SPEC_VARS ?= MACHINE 133# this is what we started with 134TARGET_SPEC = ${TARGET_SPEC_VARS:@v@${$v:U}@:ts,} 135# this is what we mostly use below 136DEP_TARGET_SPEC = ${TARGET_SPEC_VARS:S,^,DEP_,:@v@${$v:U}@:ts,} 137# make sure we have defaults 138.for v in ${TARGET_SPEC_VARS} 139DEP_$v ?= ${$v} 140.endfor 141 142.if ${TARGET_SPEC_VARS:[#]} > 1 143# Ok, this gets more complex (putting it mildly). 144# In order to stay sane, we need to ensure that all the build_dirs 145# we compute below are fully qualified wrt DEP_TARGET_SPEC. 146# The makefiles may only partially specify (eg.
