I tried to reproduce this, and blatantly failed. The core problem is that the .lib (gkmedias.lib for this one, mozjs.lib for comment 0) is not copied in dist/lib when it should be. Except that no matter what i do locally, the .lib is always copied. In fact, it's even copied when it shouldn't... The only way i can think of that would lead to this happening is if the .lib created by msvc is somehow older than the one already in dist/lib, which would suggest some clock problem or something alike. When that happens again, it would be nice to either isolate the builder or preserve the objdir somehow (move it to some temporary place) so that one can look at what exactly is going on with these .libs.

https://tbpl.mozilla.org/php/getParsedLog.php?id=15713801&tree=Mozilla-Inbound from the same patch landing again after being backed out, but thanks to slave affinity meaning it's the slave most likely to be picked for the next inbound win32 debug build and it being after 5 Eastern, I probably won't get the objdir preserved for you. Slightly higher odds when that merges to m-c, since there's less likely to be another of the same job right after it finishes.

https://tbpl.mozilla.org/php/getParsedLog.php?id=15785558&tree=Fx-Team Do I have to clobber fx-team Win64 now?

All of Windows, not just Win64 - it's pure luck (and the fact that a lot of objdirs get removed to make space, so we do a lot of clobber builds) that you made it that far.

Thanks, I've clobbered all of Windows, but not before I got this one again: https://tbpl.mozilla.org/php/getParsedLog.php?id=15802688&tree=Fx-Team

I think I have a fix for this problem, but I need to test it thoroughly, because this is a race condition. Also, chances are a clobber is actually *not* needed when that happens. The next time the same builder will be used, chances are very high that the build will succeed without a clobber.

Essentially, I think the problem can be expressed by this small test makefile: libs:: a b c a: touch a touch b c: b cp b c In a typical case, a is gkmedias.dll, b is gkmedias.lib and c is $(DIST)/lib/gkmedias.lib. More often than not, if you run rm a; make -f test.mk -j4 with the above, you will see: touch a touch b and that's all. That's because by the time make tries to create c, depending on b, b hasn't changed from running the rule for a. rules.mk does have an extra rule, though, which, in this simplified test case can be expressed as: b: a But it turns out it's not enough for make/pymake to be happy. However, adding an empty rule seems to do the trick (originally, i had made it a $(TOUCH) $@, but it turns out a rule that does nothing at all works as well)
