Makefile revision 217125
1# 2# $FreeBSD: head/Makefile 217125 2011-01-07 20:36:27Z imp $ 3# 4# The user-driven targets are: 5# 6# universe - *Really* build *everything* (buildworld and 7# all kernels on all architectures). 8# buildworld - Rebuild *everything*, including glue to help do 9# upgrades. 10# installworld - Install everything built by "buildworld". 11# world - buildworld + installworld, no kernel. 12# buildkernel - Rebuild the kernel and the kernel-modules. 13# installkernel - Install the kernel and the kernel-modules. 14# installkernel.debug 15# reinstallkernel - Reinstall the kernel and the kernel-modules. 16# reinstallkernel.debug 17# kernel - buildkernel + installkernel. 18# kernel-toolchain - Builds the subset of world necessary to build a kernel 19# doxygen - Build API documentation of the kernel, needs doxygen. 20# update - Convenient way to update your source tree (cvs). 21# check-old - List obsolete directories/files/libraries. 22# check-old-dirs - List obsolete directories. 23# check-old-files - List obsolete files. 24# check-old-libs - List obsolete libraries. 25# delete-old - Delete obsolete directories/files/libraries. 26# delete-old-dirs - Delete obsolete directories. 27# delete-old-files - Delete obsolete files. 28# delete-old-libs - Delete obsolete libraries. 29# targets - Print a list of supported TARGET/TARGET_ARCH pairs. 30# 31# This makefile is simple by design. The FreeBSD make automatically reads 32# the /usr/share/mk/sys.mk unless the -m argument is specified on the 33# command line. By keeping this makefile simple, it doesn't matter too 34# much how different the installed mk files are from those in the source 35# tree. This makefile executes a child make process, forcing it to use 36# the mk files from the source tree which are supposed to DTRT. 37# 38# The user-driven targets (as listed above) are implemented in Makefile.inc1. 39# 40# If you want to build your system from source be sure that /usr/obj has 41# at least 800MB of diskspace available. 42# 43# For individuals wanting to build from the sources currently on their 44# system, the simple instructions are: 45# 46# 1. `cd /usr/src' (or to the directory containing your source tree). 47# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 48# 3. `make world' 49# 50# For individuals wanting to upgrade their sources (even if only a 51# delta of a few days): 52# 53# 1. `cd /usr/src' (or to the directory containing your source tree). 54# 2. `make buildworld' 55# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 56# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 57# [steps 3. & 4. can be combined by using the "kernel" target] 58# 5. `reboot' (in single user mode: boot -s from the loader prompt). 59# 6. `mergemaster -p' 60# 7. `make installworld' 61# 8. `make delete-old' 62# 9. `mergemaster' (you may wish to use -U or -ai). 63# 10. `reboot' 64# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 65# 66# See src/UPDATING `COMMON ITEMS' for more complete information. 67# 68# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 69# cross build world for other machine types using the buildworld target, 70# and once the world is built you can cross build a kernel using the 71# buildkernel target. 72# 73# Define the user-driven targets. These are listed here in alphabetical 74# order, but that's not important. 75# 76# Targets that begin with underscore are internal targets intended for 77# developer convenience only. They are intentionally not documented and 78# completely subject to change without notice. 79# 80# For more information, see the build(7) manual page. 81# 82TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 83 check-old check-old-dirs check-old-files check-old-libs \ 84 checkdpadd clean cleandepend cleandir \ 85 delete-old delete-old-dirs delete-old-files delete-old-libs \ 86 depend distribute distributeworld distrib-dirs distribution doxygen \ 87 everything hierarchy install installcheck installkernel \ 88 installkernel.debug reinstallkernel reinstallkernel.debug \ 89 installworld kernel-toolchain libraries lint maninstall \ 90 obj objlink regress rerelease showconfig tags toolchain update \ 91 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 92 _build-tools _cross-tools _includes _libraries _depend \ 93 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 94 95TGTS+= ${SUBDIR_TARGETS} 96 97BITGTS= files includes 98BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 99TGTS+= ${BITGTS} 100 101.ORDER: buildworld installworld 102.ORDER: buildworld distributeworld 103.ORDER: buildworld buildkernel 104.ORDER: buildkernel installkernel 105.ORDER: buildkernel installkernel.debug 106.ORDER: buildkernel reinstallkernel 107.ORDER: buildkernel reinstallkernel.debug 108 109PATH= /sbin:/bin:/usr/sbin:/usr/bin 110MAKEOBJDIRPREFIX?= /usr/obj 111_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 112 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 113 -f /dev/null -V MAKEOBJDIRPREFIX dummy 114.if !empty(_MAKEOBJDIRPREFIX) 115.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 116 (in make.conf(5)) or command-line variable. 117.endif 118MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 119BINMAKE= \ 120 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 121 -m ${.CURDIR}/share/mk 122_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 123 124# 125# Make sure we have an up-to-date make(1).
