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

1054
1055 Options:
1056    -a arch        Set MACHINE_ARCH to arch.  [Default: deduced from MACHINE]
1057    -B buildid     Set BUILDID to buildid.
1058    -C cdextras    Append cdextras to CDEXTRA variable for inclusion on CD-ROM.
1059    -D dest        Set DESTDIR to dest.  [Default: destdir.MACHINE]
1060    -E             Set "expert" mode; disables various safety checks.
1061                   Should not be used without expert knowledge of the build system.
1062    -h             Print this help message.
1063    -j njob        Run up to njob jobs in parallel; see make(1) -j.
1064    -M obj         Set obj root directory to obj; sets MAKEOBJDIRPREFIX.
1065                   Unsets MAKEOBJDIR.
1066    -m mach        Set MACHINE to mach.  Some mach values are actually
1067                   aliases that set MACHINE/MACHINE_ARCH pairs.
1068                   [Default: deduced from the host system if the host
1069                   OS is NetBSD]
1070    -N noisy       Set the noisyness (MAKEVERBOSE) level of the build:
1071                       0   Minimal output ("quiet")
1072                       1   Describe what is occurring
1073                       2   Describe what is occurring and echo the actual command
1074                       3   Ignore the effect of the "@" prefix in make commands
1075                       4   Trace shell commands using the shell's -x flag
1076                   [Default: 2]
1077    -n             Show commands that would be executed, but do not execute them.
1078    -O obj         Set obj root directory to obj; sets a MAKEOBJDIR pattern.
1079                   Unsets MAKEOBJDIRPREFIX.
1080    -o             Set MKOBJDIRS=no; do not create objdirs at start of build.
1081    -R release     Set RELEASEDIR to release.  [Default: releasedir]
1082    -r             Remove contents of TOOLDIR and DESTDIR before building.
1083    -S seed        Set BUILDSEED to seed.  [Default: NetBSD-majorversion]
1084    -T tools       Set TOOLDIR to tools.  If unset, and TOOLDIR is not set in
1085                   the environment, ${toolprefix}make will be (re)built
1086                   unconditionally.
1087    -U             Set MKUNPRIVED=yes; build without requiring root privileges,
1088                   install from an UNPRIVED build with proper file permissions.
1089    -u             Set MKUPDATE=yes; do not run "make cleandir" first.
1090                   Without this, everything is rebuilt, including the tools.
1091    -V var=[value] Set variable \`var' to \`value'.
1092    -w wrapper     Create ${toolprefix}make script as wrapper.
1093                   [Default: \${TOOLDIR}/bin/${toolprefix}make-\${MACHINE}]
1094    -X x11src      Set X11SRCDIR to x11src.  [Default: /usr/xsrc]
1095    -x             Set MKX11=yes; build X11 from X11SRCDIR
1096    -Y extsrcsrc   Set EXTSRCSRCDIR to extsrcsrc.  [Default: /usr/extsrc]
1097    -y             Set MKEXTSRC=yes; build extsrc from EXTSRCSRCDIR
1098    -Z var         Unset ("zap") variable \`var'.

1554# use getmakevar before we have an up to date version of nbmake; we
1555# might already have an up to date version of nbmake in TOOLDIR, but we
1556# don't yet know where TOOLDIR is.
1557#
1558# The default value of TOOLDIR also depends on the location of the top
1559# level object directory, so $(getmakevar TOOLDIR) invoked before or
1560# after making the top level object directory may produce different
1561# results.
1562#
1563# Strictly speaking, we should do the following:
1564#
1565#    1. build a new version of nbmake in a temporary directory;
1566#    2. use the temporary nbmake to create the top level obj directory;
1567#    3. use $(getmakevar TOOLDIR) with the temporary nbmake to
1568#       get the correct value of TOOLDIR;
1569#    4. move the temporary nbmake to ${TOOLDIR}/bin/nbmake.
1570#
1571# However, people don't like building nbmake unnecessarily if their
1572# TOOLDIR has not changed since an earlier build.  We try to avoid
1573# rebuilding a temporary version of nbmake by taking some shortcuts to
1574# guess a value for TOOLDIR, looking for an existing version of nbmake
1575# in that TOOLDIR, and checking whether that nbmake is newer than the
1576# sources used to build it.

2081# To make this feasible for running without having to install includes and
2082# libraries into destdir (i.e. quick), we only run ld.  This is possible
2083# since the rump kernel is a closed namespace apart from calls to rumpuser.
2084# Therefore, if ld complains only about rumpuser symbols, rump kernel
2085# linking was successful.
2086#
2087# We test that rump links with a number of component configurations.
2088# These attempt to mimic what is encountered in the full build.
2089# See list below.  The list should probably be either autogenerated
2090# or managed elsewhere; keep it here until a better idea arises.

2092# Above all, note that THIS IS NOT A SUBSTITUTE FOR A FULL BUILD.
