testing for variables that are always defined (e.g., "make -V CC") would still print a false warning. Fix this by only passing a submake the MAKEOBJDIRPREFIX=* argument if it was present. As a result, we loose the check for -DMAKEOBJDIRPREFIX, or an esoteric "MAKEOBJDIRPREFIX = foo" (with embedded spaces), but these are unorthodox enough to not care about them. The make(1) bug mentioned in the previous revision was just fixed in make/main.c,v 1.109.

# The user-driven targets are:
|
|
#
|
|
# universe - *Really* build *everything* (buildworld and
|
|
# all kernels on all architectures).
|
|
# buildworld - Rebuild *everything*, including glue to help do
|
|
# upgrades.
|
|
# installworld - Install everything built by "buildworld".
|
|
# world - buildworld + installworld.
|
|
# buildkernel - Rebuild the kernel and the kernel-modules.
|
|
# installkernel - Install the kernel and the kernel-modules.
|
|
# installkernel.debug
|
|
# reinstallkernel - Reinstall the kernel and the kernel-modules.
|
|
# reinstallkernel.debug
|
|
# kernel - buildkernel + installkernel.
|
|
# update - Convenient way to update your source tree (cvs).
|
|
#
|
|
# This makefile is simple by design. The FreeBSD make automatically reads
|
|
# the /usr/share/mk/sys.mk unless the -m argument is specified on the
|
|
# command line. By keeping this makefile simple, it doesn't matter too
|
|
# much how different the installed mk files are from those in the source
|
|
# tree. This makefile executes a child make process, forcing it to use
|
|
# the mk files from the source tree which are supposed to DTRT.
|
|
#
|
|
# The user-driven targets (as listed above) are implemented in Makefile.inc1.
|
|
#
|
|
# If you want to build your system from source be sure that /usr/obj has
|
|
# at least 400MB of diskspace available.
|
|
#
|
|
# For individuals wanting to build from the sources currently on their
|
|
# system, the simple instructions are:
|
|
#
|
|
# 1. `cd /usr/src' (or to the directory containing your source tree).
|
|
# 2. `make world'
|
|
#
|
|
# For individuals wanting to upgrade their sources (even if only a
|
|
# delta of a few days):
|
|
#
|
|
# 1. `cd /usr/src' (or to the directory containing your source tree).
|
|
# 2. `make buildworld'
|
|
# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
|
|
# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
|
|
# 5. `reboot' (in single user mode: boot -s from the loader prompt).
|
|
# 6. `mergemaster -p'
|
|
# 7. `make installworld'
|
|
# 8. `mergemaster'
|
|
# 9. `reboot'
|
|
#
|
|
# See src/UPDATING `COMMON ITEMS' for more complete information.
|
|
#
|
|
# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
|
|
# cross build world for other architectures using the buildworld target,
|
|
# and once the world is built you can cross build a kernel using the
|
|
# buildkernel target.
|
|
#
|
|
# Define the user-driven targets. These are listed here in alphabetical
|
|
# order, but that's not important.
|
|
#
|
|
# Targets that begin with underscore are internal targets intended for
|
|
# developer convenience only. They are intentionally not documented and
|
|
# completely subject to change without notice.
