Makefile revision 251750
1# 2# $FreeBSD: head/Makefile 251750 2013-06-14 16:30:11Z sjg $ 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# kernel-toolchains - Build kernel-toolchain for all universe targets. 22# doxygen - Build API documentation of the kernel, needs doxygen. 23# update - Convenient way to update your source tree(s). 24# check-old - List obsolete directories/files/libraries. 25# check-old-dirs - List obsolete directories. 26# check-old-files - List obsolete files. 27# check-old-libs - List obsolete libraries. 28# delete-old - Delete obsolete directories/files. 29# delete-old-dirs - Delete obsolete directories. 30# delete-old-files - Delete obsolete files. 31# delete-old-libs - Delete obsolete libraries. 32# targets - Print a list of supported TARGET/TARGET_ARCH pairs 33# for world and kernel targets. 34# toolchains - Build a toolchain for all world and kernel targets. 35# 36# This makefile is simple by design. The FreeBSD make automatically reads 37# the /usr/share/mk/sys.mk unless the -m argument is specified on the 38# command line. By keeping this makefile simple, it doesn't matter too 39# much how different the installed mk files are from those in the source 40# tree. This makefile executes a child make process, forcing it to use 41# the mk files from the source tree which are supposed to DTRT. 42# 43# Most of the user-driven targets (as listed above) are implemented in 44# Makefile.inc1. The exceptions are universe, tinderbox and targets. 45# 46# If you want to build your system from source be sure that /usr/obj has 47# at least 1GB of diskspace available. A complete 'universe' build requires 48# about 15GB of space. 49# 50# For individuals wanting to build from the sources currently on their 51# system, the simple instructions are: 52# 53# 1. `cd /usr/src' (or to the directory containing your source tree). 54# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 55# 3. `make world' 56# 57# For individuals wanting to upgrade their sources (even if only a 58# delta of a few days): 59# 60# 1. `cd /usr/src' (or to the directory containing your source tree). 61# 2. `make buildworld' 62# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 63# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 64# [steps 3. & 4. can be combined by using the "kernel" target] 65# 5. `reboot' (in single user mode: boot -s from the loader prompt). 66# 6. `mergemaster -p' 67# 7. `make installworld' 68# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 69# 9. `make delete-old' 70# 10. `reboot' 71# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 72# 73# See src/UPDATING `COMMON ITEMS' for more complete information. 74# 75# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 76# cross build world for other machine types using the buildworld target, 77# and once the world is built you can cross build a kernel using the 78# buildkernel target. 79# 80# Define the user-driven targets. These are listed here in alphabetical 81# order, but that's not important. 82# 83# Targets that begin with underscore are internal targets intended for 84# developer convenience only. They are intentionally not documented and 85# completely subject to change without notice. 86# 87# For more information, see the build(7) manual page. 88# 89TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 90 check-old check-old-dirs check-old-files check-old-libs \ 91 checkdpadd clean cleandepend cleandir \ 92 delete-old delete-old-dirs delete-old-files delete-old-libs \ 93 depend distribute distributekernel distributekernel.debug \ 94 distributeworld distrib-dirs distribution doxygen \ 95 everything hier hierarchy install installcheck installkernel \ 96 installkernel.debug packagekernel packageworld \ 97 reinstallkernel reinstallkernel.debug \ 98 installworld kernel-toolchain libraries lint maninstall \ 99 obj objlink regress rerelease showconfig tags toolchain update \ 100 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 101 _build-tools _cross-tools _includes _libraries _depend \ 102 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 103 104TGTS+= ${SUBDIR_TARGETS} 105 106BITGTS= files includes 107BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 108TGTS+= ${BITGTS} 109 110.ORDER: buildworld installworld 111.ORDER: buildworld distributeworld 112.ORDER: buildworld buildkernel 113.ORDER: buildkernel installkernel 114.ORDER: buildkernel installkernel.debug 115.ORDER: buildkernel reinstallkernel 116.ORDER: buildkernel reinstallkernel.debug 117 118PATH= /sbin:/bin:/usr/sbin:/usr/bin 119MAKEOBJDIRPREFIX?= /usr/obj 120_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 121 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 122 -f /dev/null -V MAKEOBJDIRPREFIX dummy 123.if !empty(_MAKEOBJDIRPREFIX) 124.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 125 (in make.conf(5)) or command-line variable. 126.endif 127MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 128BINMAKE= \ 129 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 130 -m ${.CURDIR}/share/mk 131_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH} 132 133# Guess machine architecture from machine type, and vice versa. 134.if !defined(TARGET_ARCH) && defined(TARGET) 135_TARGET_ARCH= ${TARGET:S/pc98/i386/} 136.elif !defined(TARGET) && defined(TARGET_ARCH) && \ 137 ${TARGET_ARCH} != ${MACHINE_ARCH} 138_TARGET= ${TARGET_ARCH:C/mips(n32|64)?(el)?/mips/:C/arm(v6)?(eb)?/arm/} 139.endif 140# Legacy names, for another transition period mips:mips(n32|64)?eb -> mips:mips\1 141.if defined(TARGET) && defined(TARGET_ARCH) && \ 142 ${TARGET} == "mips" && ${TARGET_ARCH:Mmips*eb} 143_TARGET_ARCH= ${TARGET_ARCH:C/eb$//} 144.warning "TARGET_ARCH of ${TARGET_ARCH} is deprecated in favor of ${_TARGET_ARCH}" 145.endif 146.if defined(TARGET) && ${TARGET} == "mips" && defined(TARGET_BIG_ENDIAN) 147.warning "TARGET_BIG_ENDIAN is no longer necessary for MIPS.
