[The example context here for extracted materials is a amd64 -> armv6 cross
build.]
In my recent experimentation with WITH_META_MODE=yes I’ve had multiple
occasions when after updating /usr/src I attempt buildworld buildkernel and end
up with something like:
> --- lib/ncurses/ncursesw__L ---
> Building /usr/obj/clang/arm.armv6/usr/src/lib/ncurses/ncursesw/init_keytry.h
> --- init_keytry.h ---
> sh: ./make_keys: Exec format error
> *** [init_keytry.h] Error code 126
>
> make[4]: stopped in /usr/src/lib/ncurses/ncursesw
> 1 error
>
> make[4]: stopped in /usr/src/lib/ncurses/ncursesw
> *** [lib/ncurses/ncursesw__L] Error code 2
I’ve also had such for powerpc being the target and make toolchain in use
(preparing for buildkernel without buildworld).
There are multiple instances of make_keys construction in the builds. Here it
looks like:
> # grep make_keys
> ~/sys_typescripts/typescript_make_rpi2_nodebug_clang_bootstrap-amd64-host-2016-06-01:15:17:28
> Building /usr/obj/clang/arm.armv6/usr/src/lib/ncurses/ncursesw/make_keys
> Building /usr/obj/clang/arm.armv6/usr/src/lib/ncurses/ncurses/make_keys
> Building /usr/obj/clang/arm.armv6/usr/src/lib/ncurses/ncursesw/make_keys
> sh: ./make_keys: Exec format error
Note that ncursesw has two Building lines above with the same path listed.
cleanworld and then retrying the sequence desired always seems to work but is a
complete rebuild.
As for src.conf (example is for the amd64 -> armv6 cross build):
> # more ~/src.configs/src.conf.rpi2-clang-bootstrap.amd64-host
> TO_TYPE=armv6
> #
> KERNCONF=RPI2-NODBG
> TARGET=arm
> .if ${.MAKE.LEVEL} == 0
> TARGET_ARCH=${TO_TYPE}
> .export TARGET_ARCH
> .endif

The amd64 context is at -r301139 and the rpi2/armv6 build was attempting to
update to -r301139 from -r300944.
