Makefile revision 217273
1# 2# $FreeBSD: head/Makefile 217273 2011-01-11 18:32:05Z imp $ 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 stop on first failure. 9# buildworld - Rebuild *everything*, including glue to help do 10# upgrades. 11# installworld - Install everything built by "buildworld". 12# world - buildworld + installworld, no kernel. 13# buildkernel - Rebuild the kernel and the kernel-modules. 14# installkernel - Install the kernel and the kernel-modules. 15# installkernel.debug 16# reinstallkernel - Reinstall the kernel and the kernel-modules. 17# reinstallkernel.debug 18# kernel - buildkernel + installkernel. 19# kernel-toolchain - Builds the subset of world necessary to build a kernel 20# doxygen - Build API documentation of the kernel, needs doxygen. 21# update - Convenient way to update your source tree (cvs). 22# check-old - List obsolete directories/files/libraries. 23# check-old-dirs - List obsolete directories. 24# check-old-files - List obsolete files. 25# check-old-libs - List obsolete libraries. 26# delete-old - Delete obsolete directories/files/libraries. 27# delete-old-dirs - Delete obsolete directories. 28# delete-old-files - Delete obsolete files. 29# delete-old-libs - Delete obsolete libraries. 30# targets - Print a list of supported TARGET/TARGET_ARCH pairs. 31# 32# This makefile is simple by design. The FreeBSD make automatically reads 33# the /usr/share/mk/sys.mk unless the -m argument is specified on the 34# command line. By keeping this makefile simple, it doesn't matter too 35# much how different the installed mk files are from those in the source 36# tree. This makefile executes a child make process, forcing it to use 37# the mk files from the source tree which are supposed to DTRT. 38# 39# Most of the user-driven targets (as listed above) are implemented in 40# Makefile.inc1. The exceptions are universe, tingerbox and targets. 41# 42# If you want to build your system from source be sure that /usr/obj has 43# at least 800MB of diskspace available. 44# 45# For individuals wanting to build from the sources currently on their 46# system, the simple instructions are: 47# 48# 1. `cd /usr/src' (or to the directory containing your source tree). 49# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 50# 3. `make world' 51# 52# For individuals wanting to upgrade their sources (even if only a 53# delta of a few days): 54# 55# 1. `cd /usr/src' (or to the directory containing your source tree). 56# 2. `make buildworld' 57# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 58# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 59# [steps 3. & 4. can be combined by using the "kernel" target] 60# 5. `reboot' (in single user mode: boot -s from the loader prompt). 61# 6. `mergemaster -p' 62# 7. `make installworld' 63# 8. `make delete-old' 64# 9. `mergemaster' (you may wish to use -U or -ai). 65# 10. `reboot' 66# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 67# 68# See src/UPDATING `COMMON ITEMS' for more complete information. 69# 70# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 71# cross build world for other machine types using the buildworld target, 72# and once the world is built you can cross build a kernel using the 73# buildkernel target. 74# 75# Define the user-driven targets. These are listed here in alphabetical 76# order, but that's not important. 77# 78# Targets that begin with underscore are internal targets intended for 79# developer convenience only. They are intentionally not documented and 80# completely subject to change without notice. 81# 82# For more information, see the build(7) manual page. 83# 84TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 85 check-old check-old-dirs check-old-files check-old-libs \ 86 checkdpadd clean cleandepend cleandir \ 87 delete-old delete-old-dirs delete-old-files delete-old-libs \ 88 depend distribute distributeworld distrib-dirs distribution doxygen \ 89 everything hierarchy install installcheck installkernel \ 90 installkernel.debug reinstallkernel reinstallkernel.debug \ 91 installworld kernel-toolchain libraries lint maninstall \ 92 obj objlink regress rerelease showconfig tags toolchain update \ 93 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 94 _build-tools _cross-tools _includes _libraries _depend \ 95 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 96 97TGTS+= ${SUBDIR_TARGETS} 98 99BITGTS= files includes 100BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 101TGTS+= ${BITGTS} 102 103.ORDER: buildworld installworld 104.ORDER: buildworld distributeworld 105.ORDER: buildworld buildkernel 106.ORDER: buildkernel installkernel 107.ORDER: buildkernel installkernel.debug 108.ORDER: buildkernel reinstallkernel 109.ORDER: buildkernel reinstallkernel.debug 110 111PATH= /sbin:/bin:/usr/sbin:/usr/bin 112MAKEOBJDIRPREFIX?= /usr/obj 113_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 114 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 115 -f /dev/null -V MAKEOBJDIRPREFIX dummy 116.if !empty(_MAKEOBJDIRPREFIX) 117.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 118 (in make.conf(5)) or command-line variable. 119.endif 120MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 121BINMAKE= \ 122 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 123 -m ${.CURDIR}/share/mk 124_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 125 126# 127# Make sure we have an up-to-date make(1).
