Thanks, James, that worked. I have to admit I am a bit sloppy on
tracking all the flag days...
Another problem showed up, though: the box I was buiding on has 4GB RAM,
and about 2.5 GB available when I start nightly (according to vmstat).
However, the build failed with an "out of space" error (mksh: Fatal
error: fork failed: Not enough space).
Checking opensolaris.sh, I noticed that the number of parallel jobs is
calculated as follows:
maxjobs() {
ncpu=`/usr/sbin/psrinfo -p`
expr $ncpu \* 2 + 2
}
I fixed the number of jobs to 1, and the build succeeded after 7(!) hours.
I have a dual-core box, thus the original number of jobs was 4. Issues:
- Is it expected that more than 4GB or memory are needed just to build
the kernel with default settings?
- psrinfo -p returns the number of sockets (physical CPUs), not the
number of cores. This would make a quad-core single-socket machine not
work at its full capacity?
