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.
1065 -j njob Run up to njob jobs in parallel; see make(1) -j.
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")
1074 1 Describe what is occurring
1075 2 Describe what is occurring and echo the actual command
1076 3 Ignore the effect of the "@" prefix in make commands
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]
1084 -r Remove contents of TOOLDIR and DESTDIR before building.
1085 -S seed Set BUILDSEED to seed. [Default: NetBSD-majorversion]
1086 -T tools Set TOOLDIR to tools. If unset, and TOOLDIR is not set in
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]
