and that in turn says it is generated from rescue.conf
by crunchgen 0.2. The rescue.mk file includes the rule:
tar_make:
(cd $(tar_SRCDIR) && \
$(MAKE) $(BUILDOPTS) $(tar_OPTS) depend &&\
$(MAKE) $(BUILDOPTS) $(tar_OPTS) $(tar_OBJS))
and my guess is that construct is not '-j' safe.
I have no idea how to fix that, or even if I'm on the right
track, but perhaps the above will be useful to someone who
understands parallel makes more than I do...
I don't see how this construct cannot be parallel make safe.
The && requires that the third line check the result of the
second before continuing. It doesn't make sense.
Yeah, I don't know how these pieces all come together (or
don't come together, as the case may be). Nevertheless, it
is true that make is apparently trying a 'make addext.o'
before that .depend file exists. Perhaps this is a bug, or
maybe I'm just barking up the wrong tree...
I'm going to try a few more tests, and see if I can make some
sense out of this.
Given that 'make buildworld' is going to effectively do:
cd /usr/src/rescue
make obj
[...other stuff...]
cd /usr/src/rescue
make includes
[...other stuff...]
cd /usr/src/rescue
make depend
[...other stuff...]
it would be nice if *that* 'make depend' could result in all
of these .depend files being created. That is clearly not
the case at the moment.
