Makefile revision 217815
1# 2# $FreeBSD: head/Makefile 217815 2011-01-25 08:13:31Z bz $ 3# 4# The user-driven targets are: 5# 6# universe - *Really* build *everything* (buildworld and 7# all kernels on all architectures). 8# tinderbox - Same as universe, but presents a list of failed build 9# targets and exits with an error if there were any. 10# buildworld - Rebuild *everything*, including glue to help do 11# upgrades. 12# installworld - Install everything built by "buildworld". 13# world - buildworld + installworld, no kernel. 14# buildkernel - Rebuild the kernel and the kernel-modules. 15# installkernel - Install the kernel and the kernel-modules. 16# installkernel.debug 17# reinstallkernel - Reinstall the kernel and the kernel-modules. 18# reinstallkernel.debug 19# kernel - buildkernel + installkernel. 20# kernel-toolchain - Builds the subset of world necessary to build a kernel 21# doxygen - Build API documentation of the kernel, needs doxygen. 22# update - Convenient way to update your source tree (cvs). 23# check-old - List obsolete directories/files/libraries. 24# check-old-dirs - List obsolete directories. 25# check-old-files - List obsolete files. 26# check-old-libs - List obsolete libraries. 27# delete-old - Delete obsolete directories/files/libraries. 28# delete-old-dirs - Delete obsolete directories. 29# delete-old-files - Delete obsolete files. 30# delete-old-libs - Delete obsolete libraries. 31# targets - Print a list of supported TARGET/TARGET_ARCH pairs 32# for world and kernel targets. 33# 34# This makefile is simple by design. The FreeBSD make automatically reads 35# the /usr/share/mk/sys.mk unless the -m argument is specified on the 36# command line. By keeping this makefile simple, it doesn't matter too 37# much how different the installed mk files are from those in the source 38# tree. This makefile executes a child make process, forcing it to use 39# the mk files from the source tree which are supposed to DTRT. 40# 41# Most of the user-driven targets (as listed above) are implemented in 42# Makefile.inc1. The exceptions are universe, tinderbox and targets. 43# 44# If you want to build your system from source be sure that /usr/obj has 45# at least 1GB of diskspace available. A complete 'universe' build requires 46# about 15GB of space. 47# 48# For individuals wanting to build from the sources currently on their 49# system, the simple instructions are: 50# 51# 1. `cd /usr/src' (or to the directory containing your source tree). 52# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 53# 3. `make world' 54# 55# For individuals wanting to upgrade their sources (even if only a 56# delta of a few days): 57# 58# 1. `cd /usr/src' (or to the directory containing your source tree). 59# 2. `make buildworld' 60# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 61# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 62# [steps 3. & 4. can be combined by using the "kernel" target] 63# 5. `reboot' (in single user mode: boot -s from the loader prompt). 64# 6. `mergemaster -p' 65# 7. `make installworld' 66# 8. `make delete-old' 67# 9. `mergemaster' (you may wish to use -U or -ai). 68# 10. `reboot' 69# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 70# 71# See src/UPDATING `COMMON ITEMS' for more complete information. 72# 73# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 74# cross build world for other machine types using the buildworld target, 75# and once the world is built you can cross build a kernel using the 76# buildkernel target. 77# 78# Define the user-driven targets. These are listed here in alphabetical 79# order, but that's not important. 80# 81# Targets that begin with underscore are internal targets intended for 82# developer convenience only. They are intentionally not documented and 83# completely subject to change without notice. 84# 85# For more information, see the build(7) manual page. 86# 87TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 88 check-old check-old-dirs check-old-files check-old-libs \ 89 checkdpadd clean cleandepend cleandir \ 90 delete-old delete-old-dirs delete-old-files delete-old-libs \ 91 depend distribute distributeworld distrib-dirs distribution doxygen \ 92 everything hierarchy install installcheck installkernel \ 93 installkernel.debug reinstallkernel reinstallkernel.debug \ 94 installworld kernel-toolchain libraries lint maninstall \ 95 obj objlink regress rerelease showconfig tags toolchain update \ 96 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 97 _build-tools _cross-tools _includes _libraries _depend \ 98 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 99 100TGTS+= ${SUBDIR_TARGETS} 101 102BITGTS= files includes 103BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 104TGTS+= ${BITGTS} 105 106.ORDER: buildworld installworld 107.ORDER: buildworld distributeworld 108.ORDER: buildworld buildkernel 109.ORDER: buildkernel installkernel 110.ORDER: buildkernel installkernel.debug 111.ORDER: buildkernel reinstallkernel 112.ORDER: buildkernel reinstallkernel.debug 113 114PATH= /sbin:/bin:/usr/sbin:/usr/bin 115MAKEOBJDIRPREFIX?= /usr/obj 116_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 117 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 118 -f /dev/null -V MAKEOBJDIRPREFIX dummy 119.if !empty(_MAKEOBJDIRPREFIX) 120.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 121 (in make.conf(5)) or command-line variable. 122.endif 123MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 124BINMAKE= \ 125 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 126 -m ${.CURDIR}/share/mk 127_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 128 129# 130# Make sure we have an up-to-date make(1).
