Makefile revision 126031
1# 2# $FreeBSD: head/Makefile 126031 2004-02-20 02:10:35Z gad $ 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. 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# update - Convenient way to update your source tree (cvs). 19# 20# This makefile is simple by design. The FreeBSD make automatically reads 21# the /usr/share/mk/sys.mk unless the -m argument is specified on the 22# command line. By keeping this makefile simple, it doesn't matter too 23# much how different the installed mk files are from those in the source 24# tree. This makefile executes a child make process, forcing it to use 25# the mk files from the source tree which are supposed to DTRT. 26# 27# The user-driven targets (as listed above) are implemented in Makefile.inc1. 28# 29# If you want to build your system from source be sure that /usr/obj has 30# at least 400MB of diskspace available. 31# 32# For individuals wanting to build from the sources currently on their 33# system, the simple instructions are: 34# 35# 1. `cd /usr/src' (or to the directory containing your source tree). 36# 2. `make world' 37# 38# For individuals wanting to upgrade their sources (even if only a 39# delta of a few days): 40# 41# 1. `cd /usr/src' (or to the directory containing your source tree). 42# 2. `make buildworld' 43# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 44# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 45# 5. `reboot' (in single user mode: boot -s from the loader prompt). 46# 6. `mergemaster -p' 47# 7. `make installworld' 48# 8. `mergemaster' 49# 9. `reboot' 50# 51# See src/UPDATING `COMMON ITEMS' for more complete information. 52# 53# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can 54# cross build world for other architectures using the buildworld target, 55# and once the world is built you can cross build a kernel using the 56# buildkernel target. 57# 58# Define the user-driven targets. These are listed here in alphabetical 59# order, but that's not important. 60# 61# Targets that begin with underscore are internal targets intended for 62# developer convenience only. They are intentionally not documented and 63# completely subject to change without notice. 64# 65TGTS= all all-man buildkernel buildworld checkdpadd clean \ 66 cleandepend cleandir depend distribute distributeworld everything \ 67 hierarchy install installcheck installkernel installkernel.debug\ 68 reinstallkernel reinstallkernel.debug installworld \ 69 libraries lint maninstall \ 70 obj objlink regress rerelease tags update \ 71 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 72 _build-tools _cross-tools _includes _libraries _depend 73 74BITGTS= files includes 75BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 76TGTS+= ${BITGTS} 77 78.ORDER: buildworld installworld 79.ORDER: buildworld distributeworld 80.ORDER: buildworld buildkernel 81.ORDER: buildkernel installkernel 82.ORDER: buildkernel installkernel.debug 83.ORDER: buildkernel reinstallkernel 84.ORDER: buildkernel reinstallkernel.debug 85 86PATH= /sbin:/bin:/usr/sbin:/usr/bin 87MAKEOBJDIRPREFIX?= /usr/obj 88MAKEPATH= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE} 89BINMAKE= \ 90 `if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo ${MAKE}; fi` \ 91 -m ${.CURDIR}/share/mk 92_MAKE= PATH=${PATH} ${BINMAKE} -f Makefile.inc1 93 94# 95# Make sure we have an up-to-date make(1).
