Makefile revision 217734
1# 2# $FreeBSD: head/Makefile 217734 2011-01-22 23:10:58Z 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# 33# This makefile is simple by design. The FreeBSD make automatically reads 34# the /usr/share/mk/sys.mk unless the -m argument is specified on the 35# command line. By keeping this makefile simple, it doesn't matter too 36# much how different the installed mk files are from those in the source 37# tree. This makefile executes a child make process, forcing it to use 38# the mk files from the source tree which are supposed to DTRT. 39# 40# Most of the user-driven targets (as listed above) are implemented in 41# Makefile.inc1. The exceptions are universe, tinderbox and targets. 42# 43# If you want to build your system from source be sure that /usr/obj has 44# at least 1GB of diskspace available. A complete 'universe' build requires 45# about 15GB of space. 46# 47# For individuals wanting to build from the sources currently on their 48# system, the simple instructions are: 49# 50# 1. `cd /usr/src' (or to the directory containing your source tree). 51# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 52# 3. `make world' 53# 54# For individuals wanting to upgrade their sources (even if only a 55# delta of a few days): 56# 57# 1. `cd /usr/src' (or to the directory containing your source tree). 58# 2. `make buildworld' 59# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 60# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 61# [steps 3. & 4. can be combined by using the "kernel" target] 62# 5. `reboot' (in single user mode: boot -s from the loader prompt). 63# 6. `mergemaster -p' 64# 7. `make installworld' 65# 8. `make delete-old' 66# 9. `mergemaster' (you may wish to use -U or -ai). 67# 10. `reboot' 68# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 69# 70# See src/UPDATING `COMMON ITEMS' for more complete information. 71# 72# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 73# cross build world for other machine types using the buildworld target, 74# and once the world is built you can cross build a kernel using the 75# buildkernel target. 76# 77# Define the user-driven targets. These are listed here in alphabetical 78# order, but that's not important. 79# 80# Targets that begin with underscore are internal targets intended for 81# developer convenience only. They are intentionally not documented and 82# completely subject to change without notice. 83# 84# For more information, see the build(7) manual page. 85# 86TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 87 check-old check-old-dirs check-old-files check-old-libs \ 88 checkdpadd clean cleandepend cleandir \ 89 delete-old delete-old-dirs delete-old-files delete-old-libs \ 90 depend distribute distributeworld distrib-dirs distribution doxygen \ 91 everything hierarchy install installcheck installkernel \ 92 installkernel.debug reinstallkernel reinstallkernel.debug \ 93 installworld kernel-toolchain libraries lint maninstall \ 94 obj objlink regress rerelease showconfig tags toolchain update \ 95 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 96 _build-tools _cross-tools _includes _libraries _depend \ 97 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 98 99TGTS+= ${SUBDIR_TARGETS} 100 101BITGTS= files includes 102BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 103TGTS+= ${BITGTS} 104 105.ORDER: buildworld installworld 106.ORDER: buildworld distributeworld 107.ORDER: buildworld buildkernel 108.ORDER: buildkernel installkernel 109.ORDER: buildkernel installkernel.debug 110.ORDER: buildkernel reinstallkernel 111.ORDER: buildkernel reinstallkernel.debug 112 113PATH= /sbin:/bin:/usr/sbin:/usr/bin 114MAKEOBJDIRPREFIX?= /usr/obj 115_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 116 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 117 -f /dev/null -V MAKEOBJDIRPREFIX dummy 118.if !empty(_MAKEOBJDIRPREFIX) 119.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 120 (in make.conf(5)) or command-line variable. 121.endif 122MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 123BINMAKE= \ 124 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 125 -m ${.CURDIR}/share/mk 126_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 127 128# 129# Make sure we have an up-to-date make(1).
