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# buildworld - Rebuild *everything*, including glue to help do 9# upgrades. 10# installworld - Install everything built by "buildworld". 11# world - buildworld + installworld, no kernel. 12# buildkernel - Rebuild the kernel and the kernel-modules. 13# installkernel - Install the kernel and the kernel-modules. 14# installkernel.debug 15# reinstallkernel - Reinstall the kernel and the kernel-modules. 16# reinstallkernel.debug 17# kernel - buildkernel + installkernel. 18# doxygen - Build API documentation of the kernel, needs doxygen. 19# update - Convenient way to update your source tree (cvs). 20# check-old - Print a list of old files/directories in the system. 21# delete-old - Delete obsolete files and directories interactively. 22# delete-old-libs - Delete obsolete libraries interactively. 23# 24# This makefile is simple by design. The FreeBSD make automatically reads 25# the /usr/share/mk/sys.mk unless the -m argument is specified on the 26# command line. By keeping this makefile simple, it doesn't matter too 27# much how different the installed mk files are from those in the source 28# tree. This makefile executes a child make process, forcing it to use 29# the mk files from the source tree which are supposed to DTRT. 30# 31# The user-driven targets (as listed above) are implemented in Makefile.inc1. 32# 33# If you want to build your system from source be sure that /usr/obj has 34# at least 400MB of diskspace available. 35# 36# For individuals wanting to build from the sources currently on their 37# system, the simple instructions are: 38# 39# 1. `cd /usr/src' (or to the directory containing your source tree). 40# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 41# 3. `make world' 42# 43# For individuals wanting to upgrade their sources (even if only a 44# delta of a few days): 45# 46# 1. `cd /usr/src' (or to the directory containing your source tree). 47# 2. `make buildworld' 48# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 49# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 50# [steps 3. & 4. can be combined by using the "kernel" target] 51# 5. `reboot' (in single user mode: boot -s from the loader prompt). 52# 6. `mergemaster -p' 53# 7. `make installworld' 54# 8. `make delete-old' 55# 9. `mergemaster' 56# 10. `reboot' 57# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 58# 59# See src/UPDATING `COMMON ITEMS' for more complete information. 60# 61# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 62# cross build world for other machine types using the buildworld target, 63# and once the world is built you can cross build a kernel using the 64# buildkernel target. 65# 66# Define the user-driven targets. These are listed here in alphabetical 67# order, but that's not important. 68# 69# Targets that begin with underscore are internal targets intended for 70# developer convenience only. They are intentionally not documented and 71# completely subject to change without notice. 72# 73TGTS= all all-man buildenv buildenvvars buildkernel buildworld check-old \ 74 checkdpadd clean cleandepend cleandir delete-old delete-old-libs \ 75 depend distribute distributeworld distrib-dirs distribution doxygen \ 76 everything hierarchy install installcheck installkernel \ 77 installkernel.debug reinstallkernel reinstallkernel.debug \ 78 installworld kernel-toolchain libraries lint maninstall \ 79 obj objlink regress rerelease showconfig tags toolchain update \ 80 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 81 _build-tools _cross-tools _includes _libraries _depend \ 82 build32 distribute32 install32 83TGTS+= ${SUBDIR_TARGETS} 84 85BITGTS= files includes 86BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 87TGTS+= ${BITGTS} 88 89.ORDER: buildworld installworld 90.ORDER: buildworld distributeworld 91.ORDER: buildworld buildkernel 92.ORDER: buildkernel installkernel 93.ORDER: buildkernel installkernel.debug 94.ORDER: buildkernel reinstallkernel 95.ORDER: buildkernel reinstallkernel.debug 96 97PATH= /sbin:/bin:/usr/sbin:/usr/bin 98MAKEOBJDIRPREFIX?= /usr/obj 99_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 100 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 101 -f /dev/null -V MAKEOBJDIRPREFIX dummy 102.if !empty(_MAKEOBJDIRPREFIX) 103.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 104 (in make.conf(5)) or command-line variable. 105.endif 106MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 107BINMAKE= \ 108 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 109 -m ${.CURDIR}/share/mk 110_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 111 112# 113# Make sure we have an up-to-date make(1).
