Something I should know about 'make buildkernel ...', but I don't.
Hi All.
Something's been bugging me about 'make buildkernel ...' (or pro'lly more
precisely, the docs): How do I re-make the kernel without first cleaning
/usr/obj/...?
After applying patches, I bump $BRANCH in /sys/conf/newvers.sh, and would
like the running kernel to reflect the current patchlevel, but not at the
expense of a complete rebuild. Something this trivial shouldn't get me in
any trouble, kernel-wise, should it?
Browsing Makefile.inc1, I see these defines:
-DNOCLEANDIR run ${MAKE} clean, instead of ${MAKE} cleandir
-DNOCLEAN do not clean at all
What does 'cleandir' do that 'clean' doesn't? Remove directory trees?
Anyway, is it as simple as:
make buildkernel -DNOCLEAN KERNCONF=...
Like I said, I should already know this.
Dave

So long as you aren't changing the kernel configuration, then you can
probably use the 'old' build mechanism:
[SNIP]
However, this is only worth doing if you're going to be recompiling
the kernel a number of times, as the first time through it will
compile everything.
Right! Most SAs these days don't effect the kernel. I usually leave
/usr/obj populated from the last build.
Note that this won't put the object files
etc. under /usr/obj...
Yeah, that's why I didn't want to do the old thang. I don't know
that it'd even work right.
But you seem to agree that something this trivial shouldn't yield a
broken kernel if /usr/obj/usr/src/sys/... is unchanged from the previous
build, right?

Just a little bit ago, I wrote: - Forwarded message from D J Hawkey Jr [EMAIL PROTECTED] - But you seem to agree that something this trivial shouldn't yield a broken kernel if /usr/obj/usr/src/sys/... is unchanged from the previous build, right? - End forwarded message - Looking further into the make files, it would appear as though all I would really have to do is 'rm /usr/obj/usr/src/sys/.../vers.*', and do the 'make buildkernel KERNCONF=...' just as usual. This sounds vaguely familiar... From the old way... Sorry if I wasted time and bandwidth. Dave -- __ __ \__ \D. J.
