https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D257616 Mark Millard <marklmi26-fbsd@yahoo.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |marklmi26-fbsd@yahoo.com --- Comment #3 from Mark Millard <marklmi26-fbsd@yahoo.com> --- I'll note that if #define __FreeBSD_version in src/tree/sys/sys/param.h has changed, rebuilds are expected behavior. So I'm assuming that has not changed. Are you saying that the following wort of sequence rebuilds the toolchain 3 times? # cd /usr/src/ # env WITH_META_MODE=3Dyes make buildworld # env WITH_META_MODE=3Dyes make buildworld # env WITH_META_MODE=3Dyes make buildworld Note that lack of any other activity between buildworld's. I do not expect the above would rebuild the toolchain 3 times. By constrast it is expected that the below sort of sequence will rebuild (or relink) more than the the above would overall: # cd /usr/src/ # env WITH_META_MODE=3Dyes make buildworld # env WITH_META_MODE=3Dyes make installworld # env WITH_META_MODE=3Dyes make buildworld # env WITH_META_MODE=3Dyes make installworld # env WITH_META_MODE=3Dyes make buildworld This is because the installworld activity will update file dates on files that WITH_META_MODE checks as an example of a dependency. WITH_META_MODE has some examples of dependency recording that could be avoided with appropriate safety. An example would be avoiding checking in the rm command having been updated, even when rm was used in the command sequence for regenerating a file. You may need to be more explicit about your sequence of steps that leads to the rebuilds that you object to. --=20 You are receiving this mail because: You are the assignee for the bug.=
