239The NetBSD build system requires a shell that supports modern POSIX
240features, as well as the "local" keyword in functions (which is a
241widely-implemented but non-standardised feature).
242
243Please re-run this script under a suitable shell.  For example:
244
245	/path/to/suitable/shell $0 ...
246
247The above command will usually enable build.sh to automatically set
248HOST_SH=/path/to/suitable/shell, but if that fails, then you may also
249need to explicitly set the HOST_SH environment variable, as follows:
250
251	HOST_SH=/path/to/suitable/shell
252	export HOST_SH
253	\${HOST_SH} $0 ...
254EOF
255    exit 1

1078
1079 Options:
1080    -a arch        Set MACHINE_ARCH to arch.  [Default: deduced from MACHINE]
1081    -B buildid     Set BUILDID to buildid.
1082    -C cdextras    Append cdextras to CDEXTRA variable for inclusion on CD-ROM.

1095    -m mach        Set MACHINE to mach.  Some mach values are actually
1096                   aliases that set MACHINE/MACHINE_ARCH pairs.
1097                   [Default: deduced from the host system if the host
1098                   OS is NetBSD]

1118                   unconditionally.
1119    -U             Set MKUNPRIVED=yes; build without requiring root privileges,
1120                   install from an UNPRIVED build with proper file permissions.
1121    -u             Set MKUPDATE=yes; do not run "make cleandir" first.
1122                   Without this, everything is rebuilt, including the tools.

1649# There is a cyclic dependency between building nbmake and choosing

1651# would like to use getmakevar to get the value of TOOLDIR; but we can't

1653# might already have an up to date version of nbmake in TOOLDIR, but we
1654# don't yet know where TOOLDIR is.
1655#
1656# The default value of TOOLDIR also depends on the location of the top
1657# level object directory, so $(getmakevar TOOLDIR) invoked before or
1658# after making the top level object directory may produce different
1659# results.
1660#
1661# Strictly speaking, we should do the following:
1662#
1663#    1. build a new version of nbmake in a temporary directory;
1664#    2. use the temporary nbmake to create the top level obj directory;
1665#    3. use $(getmakevar TOOLDIR) with the temporary nbmake to

1669# However, people don't like building nbmake unnecessarily if their
1670# TOOLDIR has not changed since an earlier build.  We try to avoid

2211# since the rump kernel is a closed namespace apart from calls to rumpuser.

2213# linking was successful.
