239 The NetBSD build system requires a shell that supports modern POSIX
240 features, as well as the "local" keyword in functions (which is a
241 widely-implemented but non-standardised feature).
242 
243 Please re-run this script under a suitable shell.  For example:
244 
245 	/path/to/suitable/shell $0 ...
246 
247 The above command will usually enable build.sh to automatically set
248 HOST_SH=/path/to/suitable/shell, but if that fails, then you may also
249 need 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 ...
254 EOF
255     exit 1
256 fi
257 
258 #
259 # }}} End shell feature tests.

1055                         patterns or exact values in MACHINE or MACHINE_ARCH.
1056 
1057  Options:
1058     -a arch        Set MACHINE_ARCH to arch.  [Default: deduced from MACHINE]
1059     -B buildid     Set BUILDID to buildid.
1060     -C cdextras    Append cdextras to CDEXTRA variable for inclusion on CD-ROM.
1061     -D dest        Set DESTDIR to dest.  [Default: destdir.MACHINE]
1062     -E             Set "expert" mode; disables various safety checks.
1063                    Should not be used without expert knowledge of the build system.
1064     -h             Print this help message.

1066     -M obj         Set obj root directory to obj; sets MAKEOBJDIRPREFIX.
1067                    Unsets MAKEOBJDIR.
1068     -m mach        Set MACHINE to mach.  Some mach values are actually
1069                    aliases that set MACHINE/MACHINE_ARCH pairs.
1070                    [Default: deduced from the host system if the host
1071                    OS is NetBSD]
1072     -N noisy       Set the noisyness (MAKEVERBOSE) level of the build:
1073                        0   Minimal output ("quiet")

1077                        4   Trace shell commands using the shell's -x flag
1078                    [Default: 2]
1079     -n             Show commands that would be executed, but do not execute them.
1080     -O obj         Set obj root directory to obj; sets a MAKEOBJDIR pattern.
1081                    Unsets MAKEOBJDIRPREFIX.
1082     -o             Set MKOBJDIRS=no; do not create objdirs at start of build.
1083     -R release     Set RELEASEDIR to release.  [Default: releasedir]

1085     -S seed        Set BUILDSEED to seed.  [Default: NetBSD-majorversion]

1087                    the environment, ${toolprefix}make will be (re)built
1088                    unconditionally.
1089     -U             Set MKUNPRIVED=yes; build without requiring root privileges,
1090                    install from an UNPRIVED build with proper file permissions.
1091     -u             Set MKUPDATE=yes; do not run "make cleandir" first.
1092                    Without this, everything is rebuilt, including the tools.
1093     -V var=[value] Set variable \`var' to \`value'.
1094     -w wrapper     Create ${toolprefix}make script as wrapper.
1095                    [Default: \${TOOLDIR}/bin/${toolprefix}make-\${MACHINE}]
1096     -X x11src      Set X11SRCDIR to x11src.  [Default: /usr/xsrc]
1097     -x             Set MKX11=yes; build X11 from X11SRCDIR
1098     -Y extsrcsrc   Set EXTSRCSRCDIR to extsrcsrc.  [Default: /usr/extsrc]
1099     -y             Set MKEXTSRC=yes; build extsrc from EXTSRCSRCDIR

1555 # if nbmake was rebuilt.
1556 #
1557 # There is a cyclic dependency between building nbmake and choosing
1558 # TOOLDIR: TOOLDIR may be affected by settings in /etc/mk.conf, so we
1559 # would like to use getmakevar to get the value of TOOLDIR; but we can't
1560 # use getmakevar before we have an up to date version of nbmake; we
1561 # might already have an up to date version of nbmake in TOOLDIR, but we
1562 # don't yet know where TOOLDIR is.
1563 #
1564 # The default value of TOOLDIR also depends on the location of the top
1565 # level object directory, so $(getmakevar TOOLDIR) invoked before or
1566 # after making the top level object directory may produce different
1567 # results.
1568 #
1569 # Strictly speaking, we should do the following:
1570 #
1571 #    1. build a new version of nbmake in a temporary directory;
1572 #    2. use the temporary nbmake to create the top level obj directory;
1573 #    3. use $(getmakevar TOOLDIR) with the temporary nbmake to
1574 #       get the correct value of TOOLDIR;
1575 #    4. move the temporary nbmake to ${TOOLDIR}/bin/nbmake.
1576 #
1577 # However, people don't like building nbmake unnecessarily if their
1578 # TOOLDIR has not changed since an earlier build.  We try to avoid
1579 # rebuilding a temporary version of nbmake by taking some shortcuts to
1580 # guess a value for TOOLDIR, looking for an existing version of nbmake
1581 # in that TOOLDIR, and checking whether that nbmake is newer than the
