The NetBSD build system requires a shell that supports modern POSIX
features, as well as the "local" keyword in functions (which is a
widely-implemented but non-standardised feature).
Please re-run this script under a suitable shell. For example:
/path/to/suitable/shell $0 ...
The above command will usually enable build.sh to automatically set
HOST_SH=/path/to/suitable/shell, but if that fails, then you may also
need to explicitly set the HOST_SH environment variable, as follows:
HOST_SH=/path/to/suitable/shell
export HOST_SH
\${HOST_SH} $0 ...

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.
cleandir Run "make cleandir". [Default unless -u is used]
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.
installmodules=idir Run "make installmodules" to \`idir' to install all
kernel modules.
modules Build kernel modules.
rumptest Do a linktest for rump (for developers).
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.

install-image Create bootable installation image in
RELEASEDIR/RELEASEMACHINEDIR/installation/installimage.
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 Append cdextras to CDEXTRA variable for inclusion on CD-ROM.
-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 Minimal output ("quiet")
1 Describe what is occurring
2 Describe what is occurring and echo the actual command
3 Ignore the effect of the "@" prefix in make commands
4 Trace shell commands using the shell's -x flag
[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]

# There is a cyclic dependency between building nbmake and choosing
# TOOLDIR: TOOLDIR may be affected by settings in /etc/mk.conf, so we
# would like to use getmakevar to get the value of TOOLDIR; but we can't
# use getmakevar before we have an up to date version of nbmake; we
# might already have an up to date version of nbmake in TOOLDIR, but we
# don't yet know where TOOLDIR is.
#
# The default value of TOOLDIR also depends on the location of the top
# level object directory, so $(getmakevar TOOLDIR) invoked before or
# after making the top level object directory may produce different
# results.
#
# Strictly speaking, we should do the following:
#
# 1. build a new version of nbmake in a temporary directory;
# 2. use the temporary nbmake to create the top level obj directory;
# 3. use $(getmakevar TOOLDIR) with the temporary nbmake to
# get the corect value of TOOLDIR;
# 4. move the temporary nbmake to ${TOOLDIR}/bin/nbmake.
#
# However, people don't like building nbmake unnecessarily if their
# TOOLDIR has not changed since an earlier build. We try to avoid
# rebuilding a temporary version of nbmake by taking some shortcuts to
# guess a value for TOOLDIR, looking for an existing version of nbmake
# in that TOOLDIR, and checking whether that nbmake is newer than the
# sources used to build it.

# Run rump build&link tests.
#
# To make this feasible for running without having to install includes and
# libraries into destdir (i.e. quick), we only run ld. This is possible
# since the rump kernel is a closed namespace apart from calls to rumpuser.
# Therefore, if ld complains only about rumpuser symbols, rump kernel
# linking was successful.
#
# We test that rump links with a number of component configurations.
# These attempt to mimic what is encountered in the full build.
# See list below. The list should probably be either autogenerated
# or managed elsewhere; keep it here until a better idea arises.
#
# Above all, note that THIS IS NOT A SUBSTITUTE FOR A FULL BUILD.
