The FreeBSD make automatically reads 51# the /usr/share/mk/sys.mk unless the -m argument is specified on the 52# command line. By keeping this makefile simple, it doesn't matter too 53# much how different the installed mk files are from those in the source 54# tree. This makefile executes a child make process, forcing it to use 55# the mk files from the source tree which are supposed to DTRT. 56# 57# Most of the user-driven targets (as listed above) are implemented in 58# Makefile.inc1. The exceptions are universe, tinderbox and targets. 59# 60# If you want to build your system from source be sure that /usr/obj has 61# at least 6GB of diskspace available. A complete 'universe' build requires 62# about 100GB of space. 63# 64# For individuals wanting to build from the sources currently on their 65# system, the simple instructions are: 66# 67# 1. `cd /usr/src' (or to the directory containing your source tree). 68# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 69# 3. `make world' 70# 71# For individuals wanting to upgrade their sources (even if only a 72# delta of a few days): 73# 74# 1. `cd /usr/src' (or to the directory containing your source tree). 75# 2. `make buildworld' 76# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 77# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 78# [steps 3. & 4. can be combined by using the "kernel" target] 79# 5. `reboot' (in single user mode: boot -s from the loader prompt). 80# 6. `mergemaster -p' 81# 7. `make installworld' 82# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 83# 9. `make delete-old' 84# 10. `reboot' 85# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 86# 87# See src/UPDATING `COMMON ITEMS' for more complete information. 88# 89# If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can 90# cross build world for other machine types using the buildworld target, 91# and once the world is built you can cross build a kernel using the 92# buildkernel target. 93# 94# Define the user-driven targets. These are listed here in alphabetical 95# order, but that's not important. 96# 97# Targets that begin with underscore are internal targets intended for 98# developer convenience only. They are intentionally not documented and 99# completely subject to change without notice. 100# 101# For more information, see the build(7) manual page. 102# 103 104# This is included so CC is set to ccache for -V, and COMPILER_TYPE/VERSION 105# can be cached for sub-makes. 106.include <bsd.compiler.mk> 107 108# Note: we use this awkward construct to be compatible with FreeBSD's 109# old make used in 10.0 and 9.2 and earlier. 110.if defined(MK_DIRDEPS_BUILD) && ${MK_DIRDEPS_BUILD} == "yes" && !make(showconfig) 111# targets/Makefile plays the role of top-level 112.include "targets/Makefile" 113.else 114 115TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 116 check check-old check-old-dirs check-old-files check-old-libs \ 117 checkdpadd checkworld clean cleandepend cleandir cleanworld \ 118 delete-old delete-old-dirs delete-old-files delete-old-libs \ 119 depend distribute distributekernel distributekernel.debug \ 120 distributeworld distrib-dirs distribution doxygen \ 121 everything hier hierarchy install installcheck installkernel \ 122 installkernel.debug packagekernel packageworld \ 123 reinstallkernel reinstallkernel.debug \ 124 installworld kernel-toolchain libraries lint maninstall \ 125 obj objlink rerelease showconfig tags toolchain update \ 126 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 127 _build-tools _cross-tools _includes _libraries _depend \ 128 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 129 xdev-links native-xtools installconfig \ 130 131TGTS+= ${SUBDIR_TARGETS} 132 133BITGTS= files includes 134BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 135TGTS+= ${BITGTS} 136 137.ORDER: buildworld installworld 138.ORDER: buildworld distributeworld 139.ORDER: buildworld buildkernel 140.ORDER: installworld distribution 141.ORDER: buildkernel installkernel 142.ORDER: buildkernel installkernel.debug 143.ORDER: buildkernel reinstallkernel 144.ORDER: buildkernel reinstallkernel.debug 145 146PATH= /sbin:/bin:/usr/sbin:/usr/bin 147MAKEOBJDIRPREFIX?= /usr/obj 148_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 149 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 150 -f /dev/null -V MAKEOBJDIRPREFIX dummy 151.if !empty(_MAKEOBJDIRPREFIX) 152.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 153 (in make.conf(5)) or command-line variable. 154.endif 155 156# We often need to use the tree's version of make to build it. 157# Choices add to complexity though. 158# We cannot blindly use a make which may not be the one we want 159# so be exlicit - until all choice is removed. 160WANT_MAKE= bmake 161MYMAKE= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}/${WANT_MAKE} 162.if defined(.PARSEDIR) 163HAVE_MAKE= bmake 164.else 165HAVE_MAKE= fmake 166.endif 167.if exists(${MYMAKE}) 168SUB_MAKE:= ${MYMAKE} -m ${.CURDIR}/share/mk 169.elif ${WANT_MAKE} != ${HAVE_MAKE} 170# It may not exist yet but we may cause it to. 171# In the case of fmake, upgrade_checks may cause a newer version to be built. 172SUB_MAKE= `test -x ${MYMAKE} && echo ${MYMAKE} || echo ${MAKE}` \ 173 -m ${.CURDIR}/share/mk 174.else 175SUB_MAKE= ${MAKE} -m ${.CURDIR}/share/mk 176.endif 177 178_MAKE= PATH=${PATH} ${SUB_MAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH} 179 180# Guess machine architecture from machine type, and vice versa. 181.if !defined(TARGET_ARCH) && defined(TARGET) 182_TARGET_ARCH= ${TARGET:S/pc98/i386/:S/arm64/aarch64/} 183.elif !defined(TARGET) && defined(TARGET_ARCH) && \ 184 ${TARGET_ARCH} != ${MACHINE_ARCH} 185_TARGET= ${TARGET_ARCH:C/mips(n32|64)?(el)?/mips/:C/arm(v6)?(eb|hf)?/arm/:C/aarch64/arm64/:C/powerpc64/powerpc/:C/riscv64/riscv/} 186.endif 187.if defined(TARGET) && !defined(_TARGET) 188_TARGET=${TARGET} 189.endif 190.if defined(TARGET_ARCH) && !defined(_TARGET_ARCH) 191_TARGET_ARCH=${TARGET_ARCH} 192.endif 193# for historical compatibility for xdev targets 194.if defined(XDEV) 195_TARGET= ${XDEV} 196.endif 197.if defined(XDEV_ARCH) 198_TARGET_ARCH= ${XDEV_ARCH} 199.endif 200# Otherwise, default to current machine type and architecture. 201_TARGET?= ${MACHINE} 202_TARGET_ARCH?= ${MACHINE_ARCH} 203 204# 205# Make sure we have an up-to-date make(1).
