To make my understanding of this clear (just in case I'm wrong):= setting > WITH_META_MODE builds only portions that does not need to be build in th= e make context. I'm not sure I parsed that correctly, so let me just say; With MK_META_MODE=3Dyes, bmake should be put into meta mode. This simply means that most targets get a .meta file, that records the expanded command line, any command output and a syscall trace. These can be very useful for debugging. More important; on an update build bmake can use them to make targets out-of-date that the normal rules miss. Any change to the expanded command line, makes the target out-of-date. Any change to any file read or executed makes the target out-of-date. = > Well, the reason writing this email is: on one system, I run almost ever= y reboot into a > "full build" and this puzzles me a bit. The long-lasting and time exhaus= ting builds are You can add -dM to your build flags to have meta_oodate() - the function that does the above, explain why it decided the target is out-of-date. The results can be enlightening. Note, if a target rebuilds without -dM saying why - then the normal make rules decided it was out-of-date. > within the LLVM/CLANG tree. They consume a lot of time.

This is spooky. Add -dM, and see if that tells you why. Also confirm that filemon is getting loaded after each reboot. If that comes and goes, that could cause the behavior you see. > I think there is something missing an I'd like to ask what is the sugges= ted way to > initially restart a full build to ensure that WITH_META_MODE gets initia= lised correctly. I think Bryan has set that up so that it should take care of itself pretty well - even toggling bewteen non-meta and meta builds should DTRT - which is why it matters if filemon was used that it is there for next build. > Well, I'm not a developer, so please be patient with my naive report. No problem. Adding -dM to your build (will add a fair bit of output), will hopefully tell you what's up. =46rom what you describe, I'd not be surprised if you see some "a build command has changed" and it only takes a few to trigger a cascade of targets out-of-date. --sjg
