Hi,
I was trying to make buildkernel a bit quieter (just listing
the name of the file being compiled).
I hoped to modify the " .c.o: " rules in share/sys.mk but apparently
kernel builds generate their own Makefile using definitions in
sys/conf/kern.pre.mk .
As a result, a patch like the one below gets most of the work done
(a few extra bits are necessary to mask the awk calls, and the
'irregular' compiler invocations).
However I could not found the rule definition used to build modules,
any idea where to look ?
And finally, is there interest in this feature ?
cheers
luigi
