The FreeBSD make automatically reads 49# the /usr/share/mk/sys.mk unless the -m argument is specified on the 50# command line. By keeping this makefile simple, it doesn't matter too 51# much how different the installed mk files are from those in the source 52# tree. This makefile executes a child make process, forcing it to use 53# the mk files from the source tree which are supposed to DTRT. 54# 55# Most of the user-driven targets (as listed above) are implemented in 56# Makefile.inc1. The exceptions are universe, tinderbox and targets. 57# 58# If you want to build your system from source be sure that /usr/obj has 59# at least 1GB of diskspace available. A complete 'universe' build requires 60# about 15GB of space. 61# 62# For individuals wanting to build from the sources currently on their 63# system, the simple instructions are: 64# 65# 1. `cd /usr/src' (or to the directory containing your source tree). 66# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 67# 3. `make world' 68# 69# For individuals wanting to upgrade their sources (even if only a 70# delta of a few days): 71# 72# 1. `cd /usr/src' (or to the directory containing your source tree). 73# 2. `make buildworld' 74# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 75# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 76# [steps 3. & 4. can be combined by using the "kernel" target] 77# 5. `reboot' (in single user mode: boot -s from the loader prompt). 78# 6. `mergemaster -p' 79# 7. `make installworld' 80# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 81# 9. `make delete-old' 82# 10. `reboot' 83# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 84# 85# See src/UPDATING `COMMON ITEMS' for more complete information. 86# 87# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 88# cross build world for other machine types using the buildworld target, 89# and once the world is built you can cross build a kernel using the 90# buildkernel target. 91# 92# Define the user-driven targets. These are listed here in alphabetical 93# order, but that's not important. 94# 95# Targets that begin with underscore are internal targets intended for 96# developer convenience only. They are intentionally not documented and 97# completely subject to change without notice. 98# 99# For more information, see the build(7) manual page. 100# 101TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 102 check-old check-old-dirs check-old-files check-old-libs \ 103 checkdpadd clean cleandepend cleandir \ 104 delete-old delete-old-dirs delete-old-files delete-old-libs \ 105 depend distribute distributekernel distributekernel.debug \ 106 distributeworld distrib-dirs distribution doxygen \ 107 everything hier hierarchy install installcheck installkernel \ 108 installkernel.debug packagekernel packageworld \ 109 reinstallkernel reinstallkernel.debug \ 110 installworld kernel-toolchain libraries lint maninstall \ 111 obj objlink regress rerelease showconfig tags toolchain update \ 112 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 113 _build-tools _cross-tools _includes _libraries _depend \ 114 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 115 native-xtools \ 116 117TGTS+= ${SUBDIR_TARGETS} 118 119BITGTS= files includes 120BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 121TGTS+= ${BITGTS} 122 123.ORDER: buildworld installworld 124.ORDER: buildworld distributeworld 125.ORDER: buildworld buildkernel 126.ORDER: buildkernel installkernel 127.ORDER: buildkernel installkernel.debug 128.ORDER: buildkernel reinstallkernel 129.ORDER: buildkernel reinstallkernel.debug 130 131PATH= /sbin:/bin:/usr/sbin:/usr/bin 132MAKEOBJDIRPREFIX?= /usr/obj 133_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 134 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 135 -f /dev/null -V MAKEOBJDIRPREFIX dummy 136.if !empty(_MAKEOBJDIRPREFIX) 137.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 138 (in make.conf(5)) or command-line variable. 139.endif 140 141# We often need to use the tree's version of make to build it. 142# Choices add to complexity though. 143# We cannot blindly use a make which may not be the one we want 144# so be exlicit - until all choice is removed. 145.if !defined(WITHOUT_BMAKE) 146WANT_MAKE= bmake 147.else 148WANT_MAKE= fmake 149.endif 150MYMAKE= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}/${WANT_MAKE} 151.if defined(.PARSEDIR) 152HAVE_MAKE= bmake 153.else 154HAVE_MAKE= fmake 155.endif 156.if exists(${MYMAKE}) 157SUB_MAKE:= ${MYMAKE} -m ${.CURDIR}/share/mk 158.elif ${WANT_MAKE} != ${HAVE_MAKE} || ${WANT_MAKE} != "bmake" 159# It may not exist yet but we may cause it to. 160# In the case of fmake, upgrade_checks may cause a newer version to be built. 161SUB_MAKE= `test -x ${MYMAKE} && echo ${MYMAKE} || echo ${MAKE}` \ 162 -m ${.CURDIR}/share/mk 163.else 164SUB_MAKE= ${MAKE} -m ${.CURDIR}/share/mk 165.endif 166 167_MAKE= PATH=${PATH} ${SUB_MAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH} 168 169# Guess machine architecture from machine type, and vice versa. 170.if !defined(TARGET_ARCH) && defined(TARGET) 171_TARGET_ARCH= ${TARGET:S/pc98/i386/} 172.elif !defined(TARGET) && defined(TARGET_ARCH) && \ 173 ${TARGET_ARCH} != ${MACHINE_ARCH} 174_TARGET= ${TARGET_ARCH:C/mips(n32|64)?(el)?/mips/:C/arm(v6)?(eb)?/arm/} 175.endif 176# Legacy names, for another transition period mips:mips(n32|64)?eb -> mips:mips\1 177.if defined(TARGET) && defined(TARGET_ARCH) && \ 178 ${TARGET} == "mips" && ${TARGET_ARCH:Mmips*eb} 179_TARGET_ARCH= ${TARGET_ARCH:C/eb$//} 180.warning "TARGET_ARCH of ${TARGET_ARCH} is deprecated in favor of ${_TARGET_ARCH}" 181.endif 182.if defined(TARGET) && ${TARGET} == "mips" && defined(TARGET_BIG_ENDIAN) 183.warning "TARGET_BIG_ENDIAN is no longer necessary for MIPS.
