Hi again...
In reply to my own email, I did some playing around last night
with the /usr/share/mk/* files, bsd.subdir.mk in particular, and came
up with:
_SUBDIRUSE: .USE
@for entry in ${SUBDIR}; do \
(if test -d ${.CURDIR}/$${entry}.${MACHINE}; then \
${ECHODIR} "===> ${DIRPRFX}$${entry}.${MACHINE}"; \
edir=$${entry}.${MACHINE}; \
cd ${.CURDIR}/$${edir}; \
else \
${ECHODIR} "===> ${DIRPRFX}$$entry"; \
edir=$${entry}; \
cd ${.CURDIR}/$${edir}; \
fi; \
${MAKE} ${MAKEFLAGS} ${.TARGET:realinstall=install} DIRPRFX=${DIRPRFX}$$edir/); \
done
The only change is adding ${MAKEFLAGS} to the ${MAKE} line so
that the -j3 flag carried down into the subdir's, so that make world
works with parellel make...
Is there any reason that I'm overlooking why this *shouldn't*
be done this way? If not, and there are no arguments against it, I'd
like to make the change a permanent feature...?
Thanks...
