test with "${MKxxx}" = "no" instead of -z "${MKxxx}"
Ignore errors when running pwd -P. (GNU coreutils incorrectly complains)
Both problems pointed out in private email from Christian Limpach.
rather than adding '-s' to make's command line in the makewrapper,
use the .SILENT target based on MAKEVERBOSE's value.
This means that you can do:
./build.sh -N 1 makewrapper
$TOOLDIR/bin/nbmake-$MACHINE
# runs at MAKEVERBOSE==1, with command lines suppressed
$TOOLDIR/bin/nbmake-$MACHINE MAKEVERBOSE=2
# runs at MAKEVERBOSE==2 for this invocation, with command lines shown
trying to use them internally to build.sh.
Fixes issue where build.sh would run "make cleandir" if MKUPDATE=yes was
set in mk.conf and -u wasn't given to build.sh.
to be at any time that build.sh is run without -o, because we need
the objdir of the top-level to exist if build.sh is going to provide
a default DESTDIR/RELEASEDIR, and with the previous code, if
MAKEOBJDIRPREFIX was used and the objdir of the source tree didn't
exist, build.sh would incorrectly determine the DESTDIR.
(mmm, obscure bugs).
* add "releasekernel=conf", to install a gzipped copy of the kernels
built by "kernel=conf" to RELEASEDIR/MACHINE/binary/kernel
build.sh:
* be more consistent in various status messages
* move the {release,}kernel=conf conf parsing code into getkernelconf()
and use in both buildkernel() and releasekernel()
* only warn once when building multiple kernels without updating the tools
the .OBJDIR of the top of the source tree, but expressing that in 1
line or less starts to get complicated). Requested by Hubert.
* When using a -el or -eb MACHINE "shortcut", use that original value
as the MACHINE for the default makewrapper filename. Requested by Simon.
which sets the appropriate MACHINE_ARCH and rewrites MACHINE to lose
the -e[bl] suffix.
* Don't default to a MACHINE_ARCH for evbmips or sbmips.
Per discussion wth Simon Burge.
* If not expert mode, provide defaults for:
DESTDIR /top/of/obj/destdir.${MACHINE}
RELEASEDIR /top/of/obj/releasedir
* Collate the various status messages output during the run
and display them at the end in a "summary report".
* Cross-check the validity of MACHINE against MACHINE_ARCH.
Fixes PR [toolchain/20193] from David Maxwell.
* Highlight that the tools will be rebuilt if UPDATE isn't set.
* Add stronger language recommending against -E unless you
* Improve whitespace use in usage()
Code stuff:
* Be consistent about using "${var}"
* Be more consistent how [ tests ] are run
* Improve some comments
* Rename getmakevar() to raw_getmakevar()
* Rename safe_getmakevar() to getmakevar()
* cd back to ${TOP} after a kernel build.
* Always keep the tmpdir around for the build (it's where the
status messages are collated, for one).
Add "makewrapper" operation to build.sh.
[The above changes were suggested by Alan Barrett on current-users@]
Fail if building as non-root unless: UNPRIVED is set, -U is given, or -E
(expert mode) is given.

Improve the examples in BUILDING.
parameters, and a list of "operations" defines what to do.
The full usage is show below. Notes:
`-b' has been deprecated (it always occurs now)
`-d' is replaced by "distribution"
`-R rel' onlys sets RELEASEDIR; use "release" to build a release
`-k kern' has been replaced by "kernel=kern"
`-i idir' has been replaced by "install=idir"
-r now occurs before nbmake is rebuilt
Add a copyright (long due!). Rework the code to (a KNF inspired) ShellNF.
Use functions appropriately. Allow `nb' prefix to be easily changed to
something else. Solve world peace (just kidding)
This is part of the (never achievable) goal of attempting to make
NetBSD easier to build...
--8<-- new usage follows --8<--
Usage: build.sh [-EnorUu] [-a arch] [-B buildid] [-D dest] [-j njob] [-M obj]
[-m mach] [-O obj] [-R release] [-T tools] [-V var=[value]]
[-w wrapper] [operation [...] ]
System build operations (all imply "obj" and "tools"):
build Run "make build"
distribution Run "make distribution" (includes etc/ files)
release Run "make release" (includes kernels & distrib media)
Other operations:
obj Run "make obj" (default unless -o)
tools Build and install tools
kernel=conf Build kernel with config file `conf'
install=idir Run "make installworld" to `idir'
(useful after 'distribution' or 'release')
Options:
-a arch Set MACHINE_ARCH to arch (otherwise deduced from MACHINE)
-B buildId Set BUILDID to buildId
-D dest Set DESTDIR to dest
-E Set "expert" mode; disables some DESTDIR checks
-j njob Run up to njob jobs in parallel; see make(1)
-M obj Set obj root directory to obj (sets MAKEOBJDIRPREFIX)
-m mach Set MACHINE to mach (not required if NetBSD native)
-n Show commands that would be executed, but do not execute them
-O obj Set obj root directory to obj (sets a MAKEOBJDIR pattern)
-o Set MKOBJDIRS=no (do not create objdirs at start of build)
-R release Set RELEASEDIR to release
-r Remove contents of TOOLDIR and DESTDIR before building
-T tools Set TOOLDIR to tools. If unset, and TOOLDIR is not set in
the environment, nbmake will be (re)built unconditionally.
-U Set UNPRIVED
-u Set UPDATE
-V v=[val] Set variable `v' to `val'
-w wrapper Create nbmake script as wrapper
(default: ${TOOLDIR}/bin/nbmake-${MACHINE})
(Thanks Alan!)
* Before attempting to use KERNOBJDIR, we now need to "make obj" in
${KERNSRCDIR}/${KERNARCHDIR}/compile, not in ${TOP}/etc as used to be
the case.
* Fix one place where getmakevar was invoked unconditionally. It needs
to be conditional on $runcmd != "echo", so that we can rely on the
existence of the new $make executable.
* Add a sanity check to getmakevar, to bomb if a similar error is
introduced in the future.
* Changed the bomb function to print to stderr instead of to stdout, and
to kill the top level shell process. Without this, an attempted bomb
from inside getmakevar did not work properly.
* Moved some duplicated code into a new safe_getmakevar function, which
calls getmakevar if that is safe, or else emits a literal '$' followed
by the variable name.
Improvements from me:
* Always 'trap "exit 1" 1 2 3 15', so the kill in bomb() doesn't cause ugly
output.
make INSTALLWORLDDIR=installworlddir installworld
after every other operation has completed.
If you want to run this target without rebuilding, use -b as well...
- Cache the output of `uname -s` and `uname -m` for future use.
* When building a kernel with the -k option, make obj in $TOP/etc to
ensure that the correct KERNOBJDIR is created and used. Previously,
KERNOBJDIR could sometimes be an objdir outside the source tree
and sometimes $TOP/sys/arch/$ARCH/compile inside the source tree,
depending on whether or not a complete build had beed done before
the kernel build.
* Renamed KERNCONFNAME to kernconfname, for consistency with what
seems to be a convention that variables local to build.sh (as
opposed to make or environment variables) have lowercase names.
* Renamed the do_buildonlytools and do_buildonlykernel variables to
do_buildtools and do_buildkernel, because the word "only" is no
longer appropriate now that more than one of them can be active
simultaneously.
* Changed a few '|| exit 1' tests to '|| bomb "message"', and added a
few more similar tests.
* Changed all 'echo "===> ..."' to use $runcmd, and added a few more
similar echos. Previously, some used $runcmd and some did not.
kernel using the $TOOLDIR toolchain. If kern doesn't contain `/', it will
be searched for in ${KERNCONFDIR} (typically, sys/arch/${MACHINE}/conf).
- Improve ./build.sh usage.
- Add some examples to the documentation.
This is heavily based on [toolchain/18739] from Alan Barrett <apb@cequrux.com>,
with improvements by me.
Obsolete NBUILDJOBS; build.sh just passes -jN through to make(1),
which inherits it cooperatively through the build tree. Fix
documentation so that it's shown to be deprecated.
If you use build -jN, please save full build logs so that errors due
to missing dependancies can be analyzed and corrected.
