Bug ID: 249957
Summary: FreeBSD head: parallel buildkernel fails because of
processes removing and recreating opt_global.h
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: misc
Assignee: b...@freebsd.org
Reporter: d8zne...@aon.at
Scenario:
- FreeBSD head running some older revision in a virtual machine (bhyve on a
12.1 host)
- /usr/src and /usr/obj mounted via NFS
- running the following command in /usr/src:
nice -20 make -j8 buildworld buildkernel KERNCONF="XYZZY_SMP XYZZY_SMP_NOSPIN
XYZZY_SMP_NOSPIN_HYPERV GENERIC" |& tee
/usr/obj$PWD/make.-j8.buildworld.buildkernel.KERNCONF=XYZZY_SMP.XYZZY_SMP_NOSPIN.XYZZY_SMP_NOSPIN_HYPERV.GENERIC.`stddate`@`hostname
-s`
Result:
- The buildworld part succeeds
- The buildkernel part always fails because various opt_global.h files are
recreated in parallel branches of the build (see the log below).
- This happens at varying levels of progress of the kernel build.
Note:
- I have had this for a long time now with head.
- The buildkernel succeeds if I omit the -j8.
