1# 2# $FreeBSD$ 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# xdev - xdev-build + xdev-install for the architecture 36# specified with XDEV and XDEV_ARCH. 37# xdev-build - Build cross-development tools. 38# xdev-install - Install cross-development tools. 39# xdev-links - Create traditional links in /usr/bin for cc, etc 40# 41# "quick" way to test all kernel builds: 42# _jflag=`sysctl -n hw.ncpu` 43# _jflag=$(($_jflag * 2)) 44# [ $_jflag -gt 12 ] && _jflag=12 45# make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag} 46# 47# This makefile is simple by design. The FreeBSD make automatically reads 48# the /usr/share/mk/sys.mk unless the -m argument is specified on the 49# command line. By keeping this makefile simple, it doesn't matter too 50# much how different the installed mk files are from those in the source 51# tree. This makefile executes a child make process, forcing it to use 52# the mk files from the source tree which are supposed to DTRT. 53# 54# Most of the user-driven targets (as listed above) are implemented in 55# Makefile.inc1. The exceptions are universe, tinderbox and targets. 56# 57# If you want to build your system from source be sure that /usr/obj has 58# at least 1GB of diskspace available. A complete 'universe' build requires 59# about 15GB of space. 60# 61# For individuals wanting to build from the sources currently on their 62# system, the simple instructions are: 63# 64# 1. `cd /usr/src' (or to the directory containing your source tree). 65# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 66# 3. `make world' 67# 68# For individuals wanting to upgrade their sources (even if only a 69# delta of a few days): 70# 71# 1. `cd /usr/src' (or to the directory containing your source tree). 72# 2. `make buildworld' 73# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 74# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 75# [steps 3. & 4. can be combined by using the "kernel" target] 76# 5. `reboot' (in single user mode: boot -s from the loader prompt). 77# 6. `mergemaster -p' 78# 7. `make installworld' 79# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 80# 9. `make delete-old' 81# 10. `reboot' 82# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 83# 84# See src/UPDATING `COMMON ITEMS' for more complete information. 85# 86# If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can 87# cross build world for other machine types using the buildworld target, 88# and once the world is built you can cross build a kernel using the 89# buildkernel target. 90# 91# Define the user-driven targets. These are listed here in alphabetical 92# order, but that's not important. 93# 94# Targets that begin with underscore are internal targets intended for 95# developer convenience only. They are intentionally not documented and 96# completely subject to change without notice. 97# 98# For more information, see the build(7) manual page. 99# 100TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 101 check-old check-old-dirs check-old-files check-old-libs \ 102 checkdpadd clean cleandepend cleandir \ 103 delete-old delete-old-dirs delete-old-files delete-old-libs \ 104 depend distribute distributekernel distributekernel.debug \ 105 distributeworld distrib-dirs distribution doxygen \ 106 everything hier hierarchy install installcheck installkernel \ 107 installkernel.debug packagekernel packageworld \ 108 reinstallkernel reinstallkernel.debug \ 109 installworld kernel-toolchain libraries lint maninstall \ 110 obj objlink regress rerelease showconfig tags toolchain update \ 111 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 112 _build-tools _cross-tools _includes _libraries _depend \ 113 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 114 xdev-links \ 115 116TGTS+= ${SUBDIR_TARGETS} 117 118BITGTS= files includes 119BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 120TGTS+= ${BITGTS} 121 122.ORDER: buildworld installworld 123.ORDER: buildworld distributeworld 124.ORDER: buildworld buildkernel 125.ORDER: buildkernel installkernel 126.ORDER: buildkernel installkernel.debug 127.ORDER: buildkernel reinstallkernel 128.ORDER: buildkernel reinstallkernel.debug 129 130PATH= /sbin:/bin:/usr/sbin:/usr/bin 131MAKEOBJDIRPREFIX?= /usr/obj 132_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 133 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 134 -f /dev/null -V MAKEOBJDIRPREFIX dummy 135.if !empty(_MAKEOBJDIRPREFIX) 136.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 137 (in make.conf(5)) or command-line variable. 138.endif 139 140# We often need to use the tree's version of make to build it. 141# Choices add to complexity though. 142# We cannot blindly use a make which may not be the one we want 143# so be exlicit - until all choice is removed. 144WANT_MAKE= bmake 145MYMAKE= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}/${WANT_MAKE} 146.if defined(.PARSEDIR) 147HAVE_MAKE= bmake 148.else 149HAVE_MAKE= fmake 150.endif 151.if exists(${MYMAKE}) 152SUB_MAKE:= ${MYMAKE} -m ${.CURDIR}/share/mk 153.elif ${WANT_MAKE} != ${HAVE_MAKE} 154# It may not exist yet but we may cause it to. 155# In the case of fmake, upgrade_checks may cause a newer version to be built. 156SUB_MAKE= `test -x ${MYMAKE} && echo ${MYMAKE} || echo ${MAKE}` \ 157 -m ${.CURDIR}/share/mk 158.else 159SUB_MAKE= ${MAKE} -m ${.CURDIR}/share/mk 160.endif 161 162_MAKE= PATH=${PATH} ${SUB_MAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH} 163 164# Guess machine architecture from machine type, and vice versa. 165.if !defined(TARGET_ARCH) && defined(TARGET) 166_TARGET_ARCH= ${TARGET:S/pc98/i386/} 167.elif !defined(TARGET) && defined(TARGET_ARCH) && \ 168 ${TARGET_ARCH} != ${MACHINE_ARCH} 169_TARGET= ${TARGET_ARCH:C/mips(n32|64)?(el)?/mips/:C/arm(v6)?(eb|hf)?/arm/} 170.endif 171.if defined(TARGET) && !defined(_TARGET) 172_TARGET=${TARGET} 173.endif 174.if defined(TARGET_ARCH) && !defined(_TARGET_ARCH) 175_TARGET_ARCH=${TARGET_ARCH} 176.endif 177# for historical compatibility for xdev targets 178.if defined(XDEV) 179_TARGET= ${XDEV} 180.endif 181.if defined(XDEV_ARCH) 182_TARGET_ARCH= ${XDEV_ARCH} 183.endif 184# Otherwise, default to current machine type and architecture. 185_TARGET?= ${MACHINE} 186_TARGET_ARCH?= ${MACHINE_ARCH} 187 188# 189# Make sure we have an up-to-date make(1).
