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. 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# check-old - Print a list of old files/directories in the system. 20# delete-old - Delete obsolete files and directories interactively. 21# delete-old-libs - Delete obsolete libraries interactively. 22# 23# This makefile is simple by design. The FreeBSD make automatically reads 24# the /usr/share/mk/sys.mk unless the -m argument is specified on the 25# command line. By keeping this makefile simple, it doesn't matter too 26# much how different the installed mk files are from those in the source 27# tree. This makefile executes a child make process, forcing it to use 28# the mk files from the source tree which are supposed to DTRT. 29# 30# The user-driven targets (as listed above) are implemented in Makefile.inc1. 31# 32# If you want to build your system from source be sure that /usr/obj has 33# at least 400MB of diskspace available. 34# 35# For individuals wanting to build from the sources currently on their 36# system, the simple instructions are: 37# 38# 1. `cd /usr/src' (or to the directory containing your source tree). 39# 2. `make world' 40# 41# For individuals wanting to upgrade their sources (even if only a 42# delta of a few days): 43# 44# 1. `cd /usr/src' (or to the directory containing your source tree). 45# 2. `make buildworld' 46# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 47# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 48# 5. `reboot' (in single user mode: boot -s from the loader prompt). 49# 6. `mergemaster -p' 50# 7. `make installworld' 51# 8. `make delete-old' 52# 9. `mergemaster' 53# 10. `reboot' 54# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 55# 56# See src/UPDATING `COMMON ITEMS' for more complete information. 57# 58# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can 59# cross build world for other architectures using the buildworld target, 60# and once the world is built you can cross build a kernel using the 61# buildkernel target. 62# 63# Define the user-driven targets. These are listed here in alphabetical 64# order, but that's not important. 65# 66# Targets that begin with underscore are internal targets intended for 67# developer convenience only.
