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

1079
1080 Options:
1081    -a arch        Set MACHINE_ARCH to arch.  [Default: deduced from MACHINE]
1082    -B buildid     Set BUILDID to buildid.
1083    -C cdextras    Append cdextras to CDEXTRA variable for inclusion on CD-ROM.
1084    -c compiler    Select compiler:

1088    -D dest        Set DESTDIR to dest.  [Default: destdir.MACHINE]
1089    -E             Set "expert" mode; disables various safety checks.

1094                   Unsets MAKEOBJDIR.
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]

1106    -n             Show commands that would be executed, but do not execute them.

1109    -o             Set MKOBJDIRS=no; do not create objdirs at start of build.
1110    -P             Set MKREPRO and MKREPRO_TIMESTAMP to the latest source

1116                   the environment, ${toolprefix}make will be (re)built
1117                   unconditionally.
1118    -U             Set MKUNPRIVED=yes; build without requiring root privileges,
1119                   install from an UNPRIVED build with proper file permissions.
1120    -u             Set MKUPDATE=yes; do not run "make cleandir" first.
1121                   Without this, everything is rebuilt, including the tools.
1122    -V var=[value] Set variable \`var' to \`value'.
1123    -w wrapper     Create ${toolprefix}make script as wrapper.
1124                   [Default: \${TOOLDIR}/bin/${toolprefix}make-\${MACHINE}]

1635#
1636# There is a cyclic dependency between building nbmake and choosing
1637# TOOLDIR: TOOLDIR may be affected by settings in /etc/mk.conf, so we
1638# would like to use getmakevar to get the value of TOOLDIR; but we can't
1639# use getmakevar before we have an up to date version of nbmake; we
1640# might already have an up to date version of nbmake in TOOLDIR, but we
1641# don't yet know where TOOLDIR is.
1642#
1643# The default value of TOOLDIR also depends on the location of the top
1644# level object directory, so $(getmakevar TOOLDIR) invoked before or
1645# after making the top level object directory may produce different
1646# results.
1647#
1648# Strictly speaking, we should do the following:
1649#
1650#    1. build a new version of nbmake in a temporary directory;
1651#    2. use the temporary nbmake to create the top level obj directory;
1652#    3. use $(getmakevar TOOLDIR) with the temporary nbmake to
1653#       get the correct value of TOOLDIR;
1654#    4. move the temporary nbmake to ${TOOLDIR}/bin/nbmake.
1655#
1656# However, people don't like building nbmake unnecessarily if their
1657# TOOLDIR has not changed since an earlier build.  We try to avoid
1658# rebuilding a temporary version of nbmake by taking some shortcuts to
1659# guess a value for TOOLDIR, looking for an existing version of nbmake
