FYI: gdb/common/Makefile calling aclocal & autoconf...

[Joel Brobecker]

FYI: I haven't had a chance to look at what the problem is, but
it seems to me that the gdb/common makefile seems to be calling
aclocal and autoconf even when it doesn't need to. I noticed that
yesterday when trying to build from scratch on a machine that did
not have these tools, and I'm seeing that again today while trying
to fix today's snapshot script (again, due to an issue related
to gdb/common/).

I have also seen it, I had to undo some unexpected configure&co. files
changes.  There is missing @MAINTAINER_MODE_TRUE@:

gdb/Makefile.in:
$(srcdir)/configure: @MAINTAINER_MODE_TRUE@ $(configure_deps)
	  cd $(srcdir) && $(AUTOCONF)
gdb/common/Makefile.in:
$(srcdir)/configure: $(srcdir)/aclocal.m4
	cd $(srcdir) && $(AUTOCONF)

plus in various other autotools generated files/rules around.


Thanks,
Jan

The continued streem of issues with having a configure in the common/
directory makes me convinced that Ppedro is right and we should go
back to explicitly list things in the gdb and gdbserver Makefiles.

Hi Yao,

as you asked the Solaris build is now also broken due to (as autoconf is
usually not present there):

I think Mark are right. We are probably on the second or third "one
last push" to make things work, and we're still not done. I'm really
sorry, but we have 3 Global Maintainers (Mark, Pedro, myself) who
think that this is the wrong way to go. We tried to perservere in
this direction despite our reservations, but it's still not working.

We've learnt a lot in the process, but I think it's time to head
in the other direction (no configure & make in common/).


Anyone strongly opposed to that move, please speak up now.
It's important, IMO, to do that soon, because we're not guarantied
that we will make everything work instantly either.  I will see if
I can produce some patches for review within a day or two (anyone
wanting to take care of that can, of course!).

I would be for:
	Re: Change gdb/common/ to use Automake
	http://sourceware.org/ml/gdb-patches/2011-02/msg00493.html

with a hope for gdb/Makefile.am later; but I have enough other patches to work
on myself.

OK, I agree with this decision, given the other direction makes us more
productive on `real code', instead of configure/make stuff.

Shall I do something, for example, revert my patch, etc?

If you can propose a patch that removes the configury, and adjusts
gdb/Makefile.in + gdbserver/Makefile.in, that's be awesome! I would
wait 24hours, however, to make sure we don't have a strong objection.

I am not opposed to the experiment, but I would defer that for later,
after we have stabilized the situation (and after we've branched 7.3!).
It would also be interesting to verify that automake solves some of
the issues that we actually faced - I don't know automake much...

I would welcome temporarily to at least put those @MAINTAINER_MODE_TRUE@ at
their right places, having to undo the diff changes in every archer+gdb branch
laying around.

I've sent out my revert patch, see
http://sourceware.org/ml/gdb-patches/2011-03/msg00521.html

b.t.w, I drafted a patch yesterday as this problem was reported.  I
didn't send it for review, because we decided to give up on this
direction.  If it is useful to you, please pick it up.

When the revert vs. automake etc. is not decided could this patch go in?

This patch is safe enough regarding the current state of things.

I hope someone may comment it more but otherwise tomorrow please check it in.

As far as I understand, the consensus among the global maintainers is
to revert.
