[-O obj] [-R release] [-S seed] [-T tools]
[-V var=[value]] [-w wrapper] [-X x11src] [-Z var]
operation [...]
Build operations (all imply "obj" and "tools"):
build Run "make build".
distribution Run "make distribution" (includes DESTDIR/etc/ files).
release Run "make release" (includes kernels & distrib media).
Other operations:
help Show this message and exit.
makewrapper Create ${toolprefix}make-\${MACHINE} wrapper and ${toolprefix}make.
Always performed.
obj Run "make obj". [Default unless -o is used]
tools Build and install tools.
install=idir Run "make installworld" to \`idir' to install all sets
except \`etc'. Useful after "distribution" or "release"
kernel=conf Build kernel with config file \`conf'
releasekernel=conf Install kernel built by kernel=conf to RELEASEDIR.
sets Create binary sets in
RELEASEDIR/RELEASEMACHINEDIR/binary/sets.
DESTDIR should be populated beforehand.
sourcesets Create source sets in RELEASEDIR/source/sets.
syspkgs Create syspkgs in
RELEASEDIR/RELEASEMACHINEDIR/binary/syspkgs.
iso-image Create CD-ROM image in RELEASEDIR/iso.
iso-image-source Create CD-ROM image with source in RELEASEDIR/iso.
params Display various make(1) parameters.
Options:
-a arch Set MACHINE_ARCH to arch. [Default: deduced from MACHINE]
-B buildId Set BUILDID to buildId.
-C cdextras Set CDEXTRA to cdextras
-D dest Set DESTDIR to dest. [Default: destdir.MACHINE]
-E Set "expert" mode; disables various safety checks.
Should not be used without expert knowledge of the build system.
-h Print this help message.
-j njob Run up to njob jobs in parallel; see make(1) -j.
-M obj Set obj root directory to obj; sets MAKEOBJDIRPREFIX.
Unsets MAKEOBJDIR.
-m mach Set MACHINE to mach; not required if NetBSD native.
-N noisy Set the noisyness (MAKEVERBOSE) level of the build:
0 Quiet
1 Operations are described, commands are suppressed
2 Full output
[Default: 2]
-n Show commands that would be executed, but do not execute them.
-O obj Set obj root directory to obj; sets a MAKEOBJDIR pattern.
Unsets MAKEOBJDIRPREFIX.
-o Set MKOBJDIRS=no; do not create objdirs at start of build.
-R release Set RELEASEDIR to release. [Default: releasedir]
-r Remove contents of TOOLDIR and DESTDIR before building.
-S seed Set BUILDSEED to seed. [Default: NetBSD-majorversion]
-T tools Set TOOLDIR to tools. If unset, and TOOLDIR is not set in
the environment, ${toolprefix}make will be (re)built unconditionally.
-U Set MKUNPRIVED=yes; build without requiring root privileges,
install from an UNPRIVED build with proper file permissions.
-u Set MKUPDATE=yes; do not run "make cleandir" first.
Without this, everything is rebuilt, including the tools.
-V v=[val] Set variable \`v' to \`val'.
-w wrapper Create ${toolprefix}make script as wrapper.
[Default: \${TOOLDIR}/bin/${toolprefix}make-\${MACHINE}]
-X x11src Set X11SRCDIR to x11src. [Default: /usr/xsrc]
-x Set MKX11=yes; build X11R6 from X11SRCDIR
-Z v Unset ("zap") variable \`v'.

# doesn't override TOOLDIR via /etc/mk.conf);
# * Failing that, search for ${toolprefix}make, nbmake, bmake, or make,
# in the PATH (this might accidentally find a non-NetBSD version of
# make, which will lead to failure in the next step);
# * If a copy of make was found above, try to use it with
