Yes. That is why I was hoping that by explicitly specifying the
Makefile.inc1 as part of the `make' command, I could make other
targets like `all' pick up the /etc/make.conf-conditionally-set
value, and Do The Right Thing.
But I couldn't find the right incantation in quick testing...
Anyway, with as many people as I see having problems with using
the unofficial unsupported-but-seems-like-it-works ``?='' version
that I've suggested to try in make.conf, I'll make a deal -- I'll
stop suggesting it, if you don't deliberately make it impossible
to use ;-) (I mean the `?=' conditional assignment in make.conf,
not the `=' absolute assignment that we all agree doesn't work,
is b0rken, should not be used, needs to be stamped from the face
of the earth, is the root of all evil, and so on)
Hmmm, no way to get targets other than `buildworld' and its ilk
to use Makefile.inc1 this way, is there? I've had to use the
`env MAKEOBJDIR=/foo...' all the times I rebuild a single module
or one binary recently, so it's no big deal for me now -- so long
as I remember.
So, no more suggestions from me to try it with make.conf. It
seems to lead people astray to do Bad Things.
thanks,
