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.

946
947 Options:
948 -a arch Set MACHINE_ARCH to arch. [Default: deduced from MACHINE]
949 -B buildid Set BUILDID to buildid.
950 -C cdextras Append cdextras to CDEXTRA variable for inclusion on CD-ROM.
951 -D dest Set DESTDIR to dest. [Default: destdir.MACHINE]
952 -E Set "expert" mode; disables various safety checks.
953 Should not be used without expert knowledge of the build system.
954 -h Print this help message.
955 -j njob Run up to njob jobs in parallel; see make(1) -j.
956 -M obj Set obj root directory to obj; sets MAKEOBJDIRPREFIX.
957 Unsets MAKEOBJDIR.
958 -m mach Set MACHINE to mach; not required if NetBSD native.
959 -N noisy Set the noisyness (MAKEVERBOSE) level of the build:
960 0 Minimal output ("quiet")
961 1 Describe what is occurring
962 2 Describe what is occurring and echo the actual command
963 3 Ignore the effect of the "@" prefix in make commands
964 4 Trace shell commands using the shell's -x flag
965 [Default: 2]
966 -n Show commands that would be executed, but do not execute them.
967 -O obj Set obj root directory to obj; sets a MAKEOBJDIR pattern.
968 Unsets MAKEOBJDIRPREFIX.
969 -o Set MKOBJDIRS=no; do not create objdirs at start of build.
970 -R release Set RELEASEDIR to release. [Default: releasedir]

977 install from an UNPRIVED build with proper file permissions.
978 -u Set MKUPDATE=yes; do not run "make cleandir" first.
979 Without this, everything is rebuilt, including the tools.
980 -V var=[value] Set variable \`var' to \`value'.
981 -w wrapper Create ${toolprefix}make script as wrapper.
