The FreeBSD make automatically reads 47# the /usr/share/mk/sys.mk unless the -m argument is specified on the 48# command line. By keeping this makefile simple, it doesn't matter too 49# much how different the installed mk files are from those in the source 50# tree. This makefile executes a child make process, forcing it to use 51# the mk files from the source tree which are supposed to DTRT. 52# 53# Most of the user-driven targets (as listed above) are implemented in 54# Makefile.inc1. The exceptions are universe, tinderbox and targets. 55# 56# If you want to build your system from source be sure that /usr/obj has 57# at least 1GB of diskspace available. A complete 'universe' build requires 58# about 15GB of space. 59# 60# For individuals wanting to build from the sources currently on their 61# system, the simple instructions are: 62# 63# 1. `cd /usr/src' (or to the directory containing your source tree). 64# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 65# 3. `make world' 66# 67# For individuals wanting to upgrade their sources (even if only a 68# delta of a few days): 69# 70# 1. `cd /usr/src' (or to the directory containing your source tree). 71# 2. `make buildworld' 72# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 73# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 74# [steps 3. & 4. can be combined by using the "kernel" target] 75# 5. `reboot' (in single user mode: boot -s from the loader prompt). 76# 6. `mergemaster -p' 77# 7. `make installworld' 78# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 79# 9. `make delete-old' 80# 10. `reboot' 81# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 82# 83# See src/UPDATING `COMMON ITEMS' for more complete information. 84# 85# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 86# cross build world for other machine types using the buildworld target, 87# and once the world is built you can cross build a kernel using the 88# buildkernel target. 89# 90# Define the user-driven targets. These are listed here in alphabetical 91# order, but that's not important. 92# 93# Targets that begin with underscore are internal targets intended for 94# developer convenience only. They are intentionally not documented and 95# completely subject to change without notice. 96# 97# For more information, see the build(7) manual page. 98# 99TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 100 check-old check-old-dirs check-old-files check-old-libs \ 101 checkdpadd clean cleandepend cleandir \ 102 delete-old delete-old-dirs delete-old-files delete-old-libs \ 103 depend distribute distributekernel distributekernel.debug \ 104 distributeworld distrib-dirs distribution doxygen \ 105 everything hier hierarchy install installcheck installkernel \ 106 installkernel.debug packagekernel packageworld \ 107 reinstallkernel reinstallkernel.debug \ 108 installworld kernel-toolchain libraries lint maninstall \ 109 obj objlink regress rerelease showconfig tags toolchain update \ 110 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 111 _build-tools _cross-tools _includes _libraries _depend \ 112 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 113 114TGTS+= ${SUBDIR_TARGETS} 115 116BITGTS= files includes 117BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 118TGTS+= ${BITGTS} 119 120.ORDER: buildworld installworld 121.ORDER: buildworld distributeworld 122.ORDER: buildworld buildkernel 123.ORDER: buildkernel installkernel 124.ORDER: buildkernel installkernel.debug 125.ORDER: buildkernel reinstallkernel 126.ORDER: buildkernel reinstallkernel.debug 127 128PATH= /sbin:/bin:/usr/sbin:/usr/bin 129MAKEOBJDIRPREFIX?= /usr/obj 130_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 131 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 132 -f /dev/null -V MAKEOBJDIRPREFIX dummy 133.if !empty(_MAKEOBJDIRPREFIX) 134.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 135 (in make.conf(5)) or command-line variable. 136.endif 137 138# We often need to use the tree's version of make to build it. 139# Choices add to complexity though. 140# We cannot blindly use a make which may not be the one we want 141# so be exlicit - until all choice is removed. 142.if !defined(WITHOUT_BMAKE) 143WANT_MAKE= bmake 144.else 145WANT_MAKE= fmake 146.endif 147MYMAKE= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}/${WANT_MAKE} 148.if defined(.PARSEDIR) 149HAVE_MAKE= bmake 150.else 151HAVE_MAKE= fmake 152.endif 153.if exists(${MYMAKE}) 154SUB_MAKE:= ${MYMAKE} -m ${.CURDIR}/share/mk 155.elif ${WANT_MAKE} != ${HAVE_MAKE} || ${WANT_MAKE} != "bmake" 156# It may not exist yet but we may cause it to. 157# In the case of fmake, upgrade_checks may cause a newer version to be built. 158SUB_MAKE= `test -x ${MYMAKE} && echo ${MYMAKE} || echo ${MAKE}` \ 159 -m ${.CURDIR}/share/mk 160.else 161SUB_MAKE= ${MAKE} -m ${.CURDIR}/share/mk 162.endif 163 164_MAKE= PATH=${PATH} ${SUB_MAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH} 165 166# Guess machine architecture from machine type, and vice versa. 167.if !defined(TARGET_ARCH) && defined(TARGET) 168_TARGET_ARCH= ${TARGET:S/pc98/i386/} 169.elif !defined(TARGET) && defined(TARGET_ARCH) && \ 170 ${TARGET_ARCH} != ${MACHINE_ARCH} 171_TARGET= ${TARGET_ARCH:C/mips(n32|64)?(el)?/mips/:C/arm(v6)?(eb)?/arm/} 172.endif 173# Legacy names, for another transition period mips:mips(n32|64)?eb -> mips:mips\1 174.if defined(TARGET) && defined(TARGET_ARCH) && \ 175 ${TARGET} == "mips" && ${TARGET_ARCH:Mmips*eb} 176_TARGET_ARCH= ${TARGET_ARCH:C/eb$//} 177.warning "TARGET_ARCH of ${TARGET_ARCH} is deprecated in favor of ${_TARGET_ARCH}" 178.endif 179.if defined(TARGET) && ${TARGET} == "mips" && defined(TARGET_BIG_ENDIAN) 180.warning "TARGET_BIG_ENDIAN is no longer necessary for MIPS.
