testing for variables that are always defined (e.g.,
"make -V CC") would still print a false warning. Fix
this by only passing a submake the MAKEOBJDIRPREFIX=*
argument if it was present. As a result, we loose
the check for -DMAKEOBJDIRPREFIX, or an esoteric
"MAKEOBJDIRPREFIX = foo" (with embedded spaces), but
these are unorthodox enough to not care about them.
The make(1) bug mentioned in the previous revision
was just fixed in make/main.c,v 1.109.
When make flags are passed to make in the environment, the string is
chopped up in an (argc,argv) vector. This happens in brk_string() and
the chopped up string is stored in static buffer. When this includes
something like "-V BINMAKE", then a pointer into the static buffer is
put on the variables list for evaluation later. However, brk_string()
is used for more than just chopping up the MAKEFLAGS env. variable, so
it's very likely that the static buffer is clobbered. In fact, this is
exactly what happens.
The result is that _MAKEOBJDIRPREFIX gets assigned whatever garbage
the child make happens to emit, causing the test to fail. Like this:
pluto2% cd /usr/src
pluto2% make -V BINMAKE
"/q/6.x/src/Makefile", line 94: MAKEOBJDIRPREFIX can only be set in environment, not as a global (in /etc/make.conf) or command-line variable.
pluto2% make -dv -V BINMAKE | & grep _MAKEOBJDIRPREFIX
Global:_MAKEOBJDIRPREFIX = }
The fix is to not use MAKEFLAGS for this, but simple pass the flags
as arguments. Ideally make(1) should be fixed but that's beyond the
scope of my attention span.
This fixes release.

-DWANT_LIB32 to the world build command line, or 'WANT_LIB32=yes' to
/etc/make.conf will include the 32 bit libraries with the build.

This is still a WIP. We needed this at work so that we could install from

the preferred and suggested sequence of commands. The fact remains
that make world does not upgrade the kernel.
Allow make world when DESTDIR has been specified, including when
DESTDIR specifies the root file system. Otherwise, print a useful

but the biggest issue is that there are situatons when
${.OBJDIR} == ${.SRCDIR}, and in those situations the previous version
would happily remove all your /usr/src while it was cleaning out the objects.
Not that *you* would be happy about it... Thanks to bde for immediately
noticing this serious possibility.
More improvements will be made to this target, but I wanted to commit this
safer version right now, before anyone lost their /usr/src due to it.

buildworld targets by default, but allow it to be done for all user
targets by introducing a boolean option, named ALWAYS_CHECK_MAKE.
This change is by no means perfect and I don't even want to claim
this to be a solution. It does however address the fact that not
everybody likes to see make(1) rebuilt simply because the regression
test failed for some reason or other, including pilot error. It
therefore serves the purpose of keeping the crowd happy until we
have something better or simply reached a compromise.
The reasons for changing the default behaviour are:
o It avoids a negative, possibly non-intuitive option,
o It's according to POLA and fond of feet,
o Only buildworld is documented to do its best to be
successful at reasonably cost.

comprised of the path to a make(1) binary (possibly the one
built by the "make" target in this Makefile), and a path to
a fresh share/mk. The idea is to allow "make release" pick
up the right "make" binary, if one exists.
This fixes release.5 I broke with the last commit here; the
second PATH here was overriding the right one from WMAKEENV
while rebuilding the "build-tools" for crunched binaries.
# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
# update the legacy support for aout. This includes all libraries, ld.so
# and boot objects. This part of build should be regarded as
# deprecated and you should _not_ expect to be able to do this past the
# release of 4.0. You have exactly one major release to move entirely
# to elf.
Now that we're past 5.0, these aren't needed at all anymore and it is
well past its freshness date.
When we call "distributeworld" as part of "make release", we set
MACHINE and MACHINE_ARCH to point to TARGET and TARGET_ARCH; this
confused src/Makefile's idea of what ${MAKEPATH}, and consequently
${MAKE}, is (well, it still confuses ${MAKEPATH}, but see below).
To overcome this problem, we now take the following approach:
- We preserve the make(1)'s idea of its argv[0], ${MAKE}.
- We check to see if ${MAKE} passes the regression tests.
- If it does, we use it. Otherwise, we build and use an
up-to-date make(1).
This fix is still not quite right, in a situation where a single
/usr/obj is shared between different architecture machines, but
it is less critical and I hope to fix that soon.

make in /usr/bin. This is both bogus and does not work under non

now install it into a safe location, and use it from there.
