Hi,
I'm running 3.0 current on my machine:
FreeBSD FreeBSD.pc.sas.com 3.0-CURRENT FreeBSD 3.0-CURRENT #1:
Mon May 11 23:04:43 EDT 1998
root@FreeBSD.pc.sas.com:/usr/src/sys/compile/FreeBSD i386
The following program gives a rather bogus result which causes
cdrecord to fail rather miserably:
main()
{
int rc;
rc = sysconf(_SC_PAGESIZE);
printf("_SC_PAGESIZE == %d\n",rc);
return(0);
}
$ make sysconftst
cc -O -pipe sysconf.c -o sysconf
$ ./sysconftst
_SC_PAGESIZE == -1
$
I'm wondering whether or not this is due to my adding the Posix
scheduling options to the kernel for cdrecord (ie: enable the
sched_get_priority_max(SCHED_RR) code).
#
# Enable Posix priority scheduling
#
options "P1003_1B"
options "_KPOSIX_PRIORITY_SCHEDULING"
options "_KPOSIX_VERSION=199309L"
Well, now I guess I'll start building a kernel without all three
options and see what happens.
Comments? Critiques? They're all welcome!
Thanks,
John
