The answer to your problem, which I finally figured out for myself, is
that
make buildkernel
only works if you've recently (sometimes immediately) done a
make buildworld
AND
**you still have the /usr/obj tree around**.
(I don't remember seeing this explicitly stated in the recent threads,
but I definitely could have missed it). If you did a make clean, or
rm-ed /usr/obj, 'make buildkernel' will NOT work.
The clue is early on in the output of buildkernel. You'll see lines
sh /usr/src/sys/kern/genassym.sh genassym.o > assym.s
nm: could not exec elf/nm in /usr/obj/usr/src/i386/usr/libexec: No
such file or
directory
Turns out Makefile.inc1 sets OBJFORMAT_PATH, which causes the exec that
script to fail.
My conclusion is that even if I've done a buildworld recently, and blew
away /usr/obj for space reasons, then I should go about building new
kernels via
cd /usr/src/sys/i386/conf
config -r MYKERNEL
make depend && make && make install
Furthermore, as long as I haven't supped since I built world, the
old-fashioned way of building a kernel is not only safe, but necessary,
if /usr/obj is cleaned.
