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# 36# "quick" way to test all kernel builds: 37# _jflag=`sysctl -n hw.ncpu` 38# _jflag=$(($_jflag * 2)) 39# [ $_jflag -gt 12 ] && _jflag=12 40# make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag} 41# 42# This makefile is simple by design. The FreeBSD make automatically reads 43# the /usr/share/mk/sys.mk unless the -m argument is specified on the 44# command line. By keeping this makefile simple, it doesn't matter too 45# much how different the installed mk files are from those in the source 46# tree. This makefile executes a child make process, forcing it to use 47# the mk files from the source tree which are supposed to DTRT. 48# 49# Most of the user-driven targets (as listed above) are implemented in 50# Makefile.inc1. The exceptions are universe, tinderbox and targets. 51# 52# If you want to build your system from source be sure that /usr/obj has 53# at least 1GB of diskspace available. A complete 'universe' build requires 54# about 15GB of space. 55# 56# For individuals wanting to build from the sources currently on their 57# system, the simple instructions are: 58# 59# 1. `cd /usr/src' (or to the directory containing your source tree). 60# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 61# 3. `make world' 62# 63# For individuals wanting to upgrade their sources (even if only a 64# delta of a few days): 65# 66# 1. `cd /usr/src' (or to the directory containing your source tree). 67# 2. `make buildworld' 68# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 69# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 70# [steps 3. & 4. can be combined by using the "kernel" target] 71# 5. `reboot' (in single user mode: boot -s from the loader prompt). 72# 6. `mergemaster -p' 73# 7. `make installworld' 74# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 75# 9. `make delete-old' 76# 10. `reboot' 77# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 78# 79# See src/UPDATING `COMMON ITEMS' for more complete information. 80# 81# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 82# cross build world for other machine types using the buildworld target, 83# and once the world is built you can cross build a kernel using the 84# buildkernel target. 85# 86# Define the user-driven targets. These are listed here in alphabetical 87# order, but that's not important. 88# 89# Targets that begin with underscore are internal targets intended for 90# developer convenience only. They are intentionally not documented and 91# completely subject to change without notice. 92# 93# For more information, see the build(7) manual page. 94# 95TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 96 check-old check-old-dirs check-old-files check-old-libs \ 97 checkdpadd clean cleandepend cleandir \ 98 delete-old delete-old-dirs delete-old-files delete-old-libs \ 99 depend distribute distributekernel distributekernel.debug \ 100 distributeworld distrib-dirs distribution doxygen \ 101 everything hier hierarchy install installcheck installkernel \ 102 installkernel.debug packagekernel packageworld \ 103 reinstallkernel reinstallkernel.debug \ 104 installworld kernel-toolchain libraries lint maninstall \ 105 obj objlink regress rerelease showconfig tags toolchain update \ 106 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 107 _build-tools _cross-tools _includes _libraries _depend \ 108 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 109 110TGTS+= ${SUBDIR_TARGETS} 111 112BITGTS= files includes 113BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 114TGTS+= ${BITGTS} 115 116.ORDER: buildworld installworld 117.ORDER: buildworld distributeworld 118.ORDER: buildworld buildkernel 119.ORDER: buildkernel installkernel 120.ORDER: buildkernel installkernel.debug 121.ORDER: buildkernel reinstallkernel 122.ORDER: buildkernel reinstallkernel.debug 123 124PATH= /sbin:/bin:/usr/sbin:/usr/bin 125MAKEOBJDIRPREFIX?= /usr/obj 126_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 127 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 128 -f /dev/null -V MAKEOBJDIRPREFIX dummy 129.if !empty(_MAKEOBJDIRPREFIX) 130.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 131 (in make.conf(5)) or command-line variable. 132.endif 133 134# We often need to use the tree's version of make to build it. 135# Choices add to complexity though. 136# We cannot blindly use a make which may not be the one we want 137# so be exlicit - until all choice is removed. 138.if !defined(WITHOUT_BMAKE) 139WANT_MAKE= bmake 140.else 141WANT_MAKE= fmake 142.endif 143MYMAKE= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}/${WANT_MAKE} 144.if defined(.PARSEDIR) 145HAVE_MAKE= bmake 146.else 147HAVE_MAKE= fmake 148.endif 149.if exists(${MYMAKE}) 150SUB_MAKE:= ${MYMAKE} -m ${.CURDIR}/share/mk 151.elif ${WANT_MAKE} != ${HAVE_MAKE} || ${WANT_MAKE} != "bmake" 152# It may not exist yet but we may cause it to. 153# In the case of fmake, upgrade_checks may cause a newer version to be built. 154SUB_MAKE= `test -x ${MYMAKE} && echo ${MYMAKE} || echo ${MAKE}` \ 155 -m ${.CURDIR}/share/mk 156.else 157SUB_MAKE= ${MAKE} -m ${.CURDIR}/share/mk 158.endif 159 160_MAKE= PATH=${PATH} ${SUB_MAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH} 161 162# Guess machine architecture from machine type, and vice versa. 163.if !defined(TARGET_ARCH) && defined(TARGET) 164_TARGET_ARCH= ${TARGET:S/pc98/i386/} 165.elif !defined(TARGET) && defined(TARGET_ARCH) && \ 166 ${TARGET_ARCH} != ${MACHINE_ARCH} 167_TARGET= ${TARGET_ARCH:C/mips(n32|64)?(el)?/mips/:C/arm(v6)?(eb)?/arm/} 168.endif 169# Legacy names, for another transition period mips:mips(n32|64)?eb -> mips:mips\1 170.if defined(TARGET) && defined(TARGET_ARCH) && \ 171 ${TARGET} == "mips" && ${TARGET_ARCH:Mmips*eb} 172_TARGET_ARCH= ${TARGET_ARCH:C/eb$//} 173.warning "TARGET_ARCH of ${TARGET_ARCH} is deprecated in favor of ${_TARGET_ARCH}" 174.endif 175.if defined(TARGET) && ${TARGET} == "mips" && defined(TARGET_BIG_ENDIAN) 176.warning "TARGET_BIG_ENDIAN is no longer necessary for MIPS.
