Makefile revision 204661
1# 2# $FreeBSD: head/Makefile 204661 2010-03-03 21:08:44Z 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# 30# This makefile is simple by design. The FreeBSD make automatically reads 31# the /usr/share/mk/sys.mk unless the -m argument is specified on the 32# command line. By keeping this makefile simple, it doesn't matter too 33# much how different the installed mk files are from those in the source 34# tree. This makefile executes a child make process, forcing it to use 35# the mk files from the source tree which are supposed to DTRT. 36# 37# The user-driven targets (as listed above) are implemented in Makefile.inc1. 38# 39# If you want to build your system from source be sure that /usr/obj has 40# at least 800MB of diskspace available. 41# 42# For individuals wanting to build from the sources currently on their 43# system, the simple instructions are: 44# 45# 1. `cd /usr/src' (or to the directory containing your source tree). 46# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 47# 3. `make world' 48# 49# For individuals wanting to upgrade their sources (even if only a 50# delta of a few days): 51# 52# 1. `cd /usr/src' (or to the directory containing your source tree). 53# 2. `make buildworld' 54# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 55# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 56# [steps 3. & 4. can be combined by using the "kernel" target] 57# 5. `reboot' (in single user mode: boot -s from the loader prompt). 58# 6. `mergemaster -p' 59# 7. `make installworld' 60# 8. `make delete-old' 61# 9. `mergemaster' (you may wish to use -U or -ai). 62# 10. `reboot' 63# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 64# 65# See src/UPDATING `COMMON ITEMS' for more complete information. 66# 67# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 68# cross build world for other machine types using the buildworld target, 69# and once the world is built you can cross build a kernel using the 70# buildkernel target. 71# 72# Define the user-driven targets. These are listed here in alphabetical 73# order, but that's not important. 74# 75# Targets that begin with underscore are internal targets intended for 76# developer convenience only. They are intentionally not documented and 77# completely subject to change without notice. 78# 79# For more information, see the build(7) manual page. 80# 81TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 82 check-old check-old-dirs check-old-files check-old-libs \ 83 checkdpadd clean cleandepend cleandir \ 84 delete-old delete-old-dirs delete-old-files delete-old-libs \ 85 depend distribute distributeworld distrib-dirs distribution doxygen \ 86 everything hierarchy install installcheck installkernel \ 87 installkernel.debug reinstallkernel reinstallkernel.debug \ 88 installworld kernel-toolchain libraries lint maninstall \ 89 obj objlink regress rerelease showconfig tags toolchain update \ 90 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 91 _build-tools _cross-tools _includes _libraries _depend \ 92 build32 distribute32 install32 xdev xdev-build xdev-install 93TGTS+= ${SUBDIR_TARGETS} 94 95BITGTS= files includes 96BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 97TGTS+= ${BITGTS} 98 99.ORDER: buildworld installworld 100.ORDER: buildworld distributeworld 101.ORDER: buildworld buildkernel 102.ORDER: buildkernel installkernel 103.ORDER: buildkernel installkernel.debug 104.ORDER: buildkernel reinstallkernel 105.ORDER: buildkernel reinstallkernel.debug 106 107PATH= /sbin:/bin:/usr/sbin:/usr/bin 108MAKEOBJDIRPREFIX?= /usr/obj 109_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 110 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 111 -f /dev/null -V MAKEOBJDIRPREFIX dummy 112.if !empty(_MAKEOBJDIRPREFIX) 113.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 114 (in make.conf(5)) or command-line variable. 115.endif 116MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 117BINMAKE= \ 118 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 119 -m ${.CURDIR}/share/mk 120_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 121 122# 123# Make sure we have an up-to-date make(1).
