FreeBSD Hints

Last update: May 4, 2022 17:05 UTC (dbea9b7d4)

If you are compiling under FreeBSD and see messages in the syslogs that indicate that the ntpd process is trying to use unavailable sched_ calls, it means you are running a kernel that does not have the POSIX scheduling calls enabled.

You have two choices:

• Ignore the messages.

• Generate a new kernel, where the kernel configuration file contains the lines:

  options		"P1003_1B"
  options		"_KPOSIX_PRIORITY_SCHEDULING"
  options		"_KPOSIX_VERSION=199309L"
