[Octave-bug-tracker] [bug #46063] Build system re-makes certain files 2 or even 3 times

[Mike Miller]

Update of bug #46063 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #6:

I think the reason these files are built twice in a single make is because
they are both BUILT_SOURCES and ALL_LOCAL_TARGETS. The "all" target depends on
BUILT_SOURCES as a prerequisite (so that builds them once) and then does a
$(MAKE) all-recursive (which builds them a second time).

I'm able to reproduce this one easily by doing a clean build, then "touch
Makefile" and "make all" again. All of the files in question have Makefile as
a prerequisite, but their timestamps are not updated when they are built.
