Updating deps/*.d files

Updating deps/*.d files

[Richard Stallman]

Is there a make target to update them?
I can't see one, and it was just a pain in the neck.

There's no make target for them.  We could add one by
appending something like the following to src/autodeps.mk:

dependencies: $(ALLOBJS)

and then one could type "make dependencies".

I'm not sure this would be a good idea, though.
Why was it a pain in the neck?  What happened?
Perhaps we could fix the underlying problem directly,
with no need for a manual "make dependencies" action.

    dependencies: $(ALLOBJS)

    and then one could type "make dependencies".

ALLOBJS seems to be a list of .o file names.  How would that do the job?
Is it that compilation also generates the deps/*.d files as a side output?

The problem was, make was failing because deps/bidi.d contained two
old .h files that don't exist any more.  I could not see any way to
update bidi.d automatically, so I edited it by hand to make things
proceed.  That doesn't seem clean.

Yes.

You could also delete bidi.d.

Yes.

The problem you bumped into has been fixed (the deps generated more
recently will "do the right thing" if one of the dependencies is
missing).
In general, "rm -rf src/deps" is simpler than editing by hand and works
about as well.

	dependencies: $(ALLOBJS)

	and then one could type "make dependencies".

My problem was that `make bidi.o' was failing.  It said that
there was no way to make a couple of .h files that were dependencies
of bidi.o, but no longer existed.

I think that `make dependencies' would have failed too.
So that is not a solution.

As they are generated at the same time the .c-file is compiled, no.
You can remove deps and recompile Emacs.
There is a configure option to disable them: --disable-autodepend.
