The FreeBSD make automatically reads 371855Ssdama# the /usr/share/mk/sys.mk unless the -m argument is specified on the 381855Ssdama# command line. By keeping this makefile simple, it doesn't matter too 391855Ssdama# much how different the installed mk files are from those in the source 401855Ssdama# tree. This makefile executes a child make process, forcing it to use 411855Ssdama# the mk files from the source tree which are supposed to DTRT. 421855Ssdama# 431855Ssdama# Most of the user-driven targets (as listed above) are implemented in 441855Ssdama# Makefile.inc1. The exceptions are universe, tinderbox and targets. 451855Ssdama# 461855Ssdama# If you want to build your system from source be sure that /usr/obj has 471855Ssdama# at least 1GB of diskspace available. A complete 'universe' build requires 481855Ssdama# about 15GB of space. 491855Ssdama# 501855Ssdama# For individuals wanting to build from the sources currently on their 511855Ssdama# system, the simple instructions are: 521855Ssdama# 531855Ssdama# 1. `cd /usr/src' (or to the directory containing your source tree). 541855Ssdama# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 551855Ssdama# 3. `make world' 561855Ssdama# 571855Ssdama# For individuals wanting to upgrade their sources (even if only a 581855Ssdama# delta of a few days): 591855Ssdama# 601855Ssdama# 1. `cd /usr/src' (or to the directory containing your source tree). 611855Ssdama# 2. `make buildworld' 621855Ssdama# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 631855Ssdama# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 641855Ssdama# [steps 3. & 4. can be combined by using the "kernel" target] 651855Ssdama# 5. `reboot' (in single user mode: boot -s from the loader prompt). 661855Ssdama# 6. `mergemaster -p' 671855Ssdama# 7. `make installworld' 681855Ssdama# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 691855Ssdama# 9. `make delete-old' 701855Ssdama# 10. `reboot' 711855Ssdama# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 721855Ssdama# 731855Ssdama# See src/UPDATING `COMMON ITEMS' for more complete information. 741855Ssdama# 751855Ssdama# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can 761855Ssdama# cross build world for other machine types using the buildworld target, 771855Ssdama# and once the world is built you can cross build a kernel using the 781855Ssdama# buildkernel target. 791855Ssdama# 801855Ssdama# Define the user-driven targets.
