I have found what appears to be a regression in Libtool 2.4.4 vs. 2.4.2 (I =
did not test 2.4.3).

When embedding LT 2.4.4 libltdl in a larger project, the first time you inv=
oke any "make" target (e.g., even "make clean"), "make" decides to run aclo=
cal in the embedded libltdl directory.

This did not happen in LT 2.4.2 and earlier.

This behavior causes other problems in the Open MPI project, but I think th=
e fact that "make" decides to invoke aclocal at all is the root cause.

Attached is a simple reproducer (if the tarball doesn't make it through ant=
i-virus scanners, the same source is on github: https://github.com/jsquyres=
/libtool-2.4.4-bug):

- untar it
- run "./autogen.sh" (which runs autoreconf)
- run "./configure"
- run "make clean"

You'll see aclocal invoked in the embedded-libltdl directory.

The problem appears to be that make is checking for ../m4/libtool.m4 file a=
s a dependency.  This file file -- and the entire ../m4 directory, for that=
 matter -- does not exist.  So make decides to fire the "run the aclocal" r=
ule.

In LT 2.4.2, make appears to check for m4/libtool.m4 (note the lack of ../)=
, and somehow decides that even though this directory/file does not exist, =
it does not need to fire the "run the aclocal" rule.

Can someone have a look at this?  This behavior is preventing the Open MPI =
project from upgrading beyond Libtool 2.4.2.

Thank you!

Any comments on this, perchance?

It's a blocker for us in the Open MPI project; it prevents us from upgradin=
g from 2.4.2.

It's a bit of a problem because some software projects, such as mac-ports a=
nd home-brew are shipping LT >=3D 2.4.3.

Hi Jeff,

I'm sorry, I didn't yet have chance to work on this... I'll try to reproduce=
 it over the holidays,
and depending on whether that makes it obvious what's happening, a fix may o=
r not be
straight forward and forthcoming.

It would certainly speed things along if you could help produce an analysis,=
 a small self
contained reproducer, a test case and/or propose a patch.

Sorry I can't be of more help for the moment,

Thanks for replying, Gary.=20

I did include what analysis I was able to do in my first email: I tracked d=
own that the problem is that the "make" rules decide to invoke aclocal in t=
he embedded libltdl because it's looking for non-existent files as dependen=
cies (it looks like the wrong path is being used somehow?). I didn't go bey=
ond that - I don't know the internals of libtool (this is a regression comp=
ared to 2.4.2).=20

I also included a reproducer, both as a tarball and as a link to a github r=
epo.=20

Hopefully that's enough to get you going in the right direction.=20

Sent from my phone. No type good.=20

Hi Jeff,

Sorry for the delay.

Perfect!  So, even though your tarball does reproduce the bug you =
describe, I first converted it to a new autotest to protect against =
future reappearance of the bug, only to discover that inside the =
testsuite everything works as it should.  Hmm.

> Hopefully that's enough to get you going in the right direction.=20

Indeed it is.  And the problem is that autoreconf, as called from the =
autogen.sh in the tarball, still runs the tools in the wrong order.  =
Autoreconf stupidly runs aclocal first, and then calls libtoolize which =
adds more m4 files to AC_CONFIG_MACRO_DIR, and that in turn causes =
aclocal.m4 to be out of date (because it needs to be regenerated to pick =
up the local versions of the libtoolize added m4 files added to =
../config/ after it was first generated).

The bootstrap script in the libtool source tree fixes this (and many =
other problems with the autogen.sh/autoreconf approach), so if you care =
to write a bootstrap.conf (by copying and hacking nearly everything out =
of libtool-2.4.4/bootstrap.conf), things are then created in the right =
order and the bug disappears.

Alternatively, you can amend your autogen.sh to something like this:

  libtoolize --install --copy --ltdl
  LIBTOOLIZE=3Dtrue autoreconf -fvi

If it worked for you in 2.4.2 in that order, then it was just a lucky =
combination of an empty local directory and installed versions of the =
macro files in the right place for aclocal.m4 to be valid on the initial =
too-early run.

In your original report, however, you said:

"The problem appears to be that make is checking for ../m4/libtool.m4 =
file as a dependency.  This file file -- and the entire ../m4 directory, =
for that matter -- does not exist.  So make decides to fire the "run the =
aclocal" rule."

...which seems odd to me, because for a subproject libltdl, the parent =
AC_CONFIG_MACRO_DIR/ACLOCAL_AMFLAGS directory is supposed to be merged =
in.  Did you mean to say "../config/libtool.m4" above?  If that =
substitution really isn't happening, then you've found a different bug - =
but I can't reproduce that one with 2.4.3, 2.4.4 nor current master.

HTH,

That's a bummer.  We always thought that The Recommended Way to run the aut=
ootols was to use autoreconf.  Specifically: we used to have a magic incant=
ation of a specific order of Autotools to bootstrap OMPI.  But that orderin=

Just to be clear: you're saying that I should invoke libtoolize *before* au=
toreconf, right?  (as opposed to appending those 2 lines at the end of my e=
xisting autogen.sh script)

I'm pretty sure that's what you're saying, and indeed, if I make my autogen=
.sh be this:

-----
$ more autogen.sh
#!/bin/sh

libtoolize --install --copy --ltdl
autoreconf -ivf --warnings=3Dall,no-obsolete,no-override -I config
-----

...then the problem goes away.  Yay!

bination of an empty local directory and installed versions of the macro fi=
les in the right place for aclocal.m4 to be valid on the initial too-early =
run.

Ever since we switched to invoking a single autoreconf (which was a loooong=
 time ago; I'd have to go spelunking through history to find out when it wa=
s done, but it was probably on the order of years ago), we've not invoked l=
ibtoolize before autoreconf.

So just to be crystal clear: is the official guidance that we should run li=
btoolize and then autoreconf, and that should always work?

A bummer indeed.  I suppose this may very well be fixed in autoconf =
master... though I'm too lazy to check :-)

Getting the order right is a difficult error-prone process with hard to =
debug side-effects, so the fewer tools you have to invoke to do the =
bootstrap, the better.  And autoreconf is several fewer than =
aclocal/automake/autoconf, even though it calls libtoolize (and =
autopoint IIRC) too late! Of course, it gets out of hand fast when you =
have to run all the gettextize bits, and gnulib-tool and throw in some =
help2mans and the like :-(

Pretty much, although without the LIBTOOLIZE=3Dtrue setting before =
calling autoreconf, it will run wastefully run libtoolize a second time, =
which may or may not throw the timestamps out of sync again, depending =
how careful I was about preserving filestamps in generated files from =
the libtoolize code when their content does not change.  I'd recommend =
keeping that setting, just in case.

The crux of the matter is that if you run `aclocal -I m4` and then put =
more files that configure.ac calls out to into m4, then the next run of =
`aclocal -I m4` necessarily generates a new and different aclocal.m4 =
(with m4_includes for the new files replacing verbatim copies of the =
/usr/share/aclocal contents).

>> If it worked for you in 2.4.2 in that order, then it was just a lucky =

Well, I hesitate to dub my word as "official"... but this is what my =
bootstrap script (and the gnulib bootstrap script) have been doing as a =
work-around for autoreconf brokenness for several years a piece with =
less weirdness than the olden days of trusting autoreconf.

Another option you have, should you worry about maintaining your own =
autogen.sh script to keep track of changes in upstream autotools =
dependencies and invocation ordering, is to use my bootstrap script (as =
used by libtool itself and m4 among others, and maintained separately at =
http://github.com/gvvaughan/bootstrap).  This nicely future-proofs you =
against upstream changes, or addition of internationalization or gnulib =
to your projects.

Is this something that needs to be reported to the Autoconf devs, or is thi=

If it's not already a known issue, I'm guessing that Open MPI may not be th=
e only project to run into this bug once other projects start upgrading to =
LT 2.4.4 (although, admittedly, there may not be many that embed libltdl).

Ahhh... I see.  I thought that the mailer had munged your previous mail and=
 there were some quotes missing from your original suggestion.  Now I grok =
what you are suggesting: setting LIBTOOLIZE to effectively be a no-op so th=

l contents).

Ok, I think I see.

That's a good suggestion; many thanks.

I'm a little hesitant to do it, however, simply because I'd prefer to get t=
he Autotools fixed correctly such that autoreconf works properly.  That's (=
supposedly) the officially-recommended Way Of Doing Things, and it should w=
ork.  Perhaps that's naive, but I'd like to stick with the Office Way as mu=
ch as possible.  As such, a 2-line workaround is much more attractive than =
a complicated non-office bootstrap script that we will potentially need to =
continually refresh from your github.

Make sense?

So I think the crux of this particular issue comes down to: do we need to r=
eport this to the Autoconf devs?

I don't really follow Autoconf development these days, but there's =

marked as a duplicate and count as an upvote on what needs fixing next.

Ok.

Sadly, however, your workaround was good enough for my toy example that I s=
ubmitted, but it did not fix the issue in the Open MPI project (i.e., I run=
 libtoolize .../LIBTOOLIZE=3Dtrue autoreconf ..., but aclocal still decides=
 to run in the libltdl directory, and Badness Ensues).

I'll have to investigate a little deeper and see what the difference is bet=
ween my toy project and what Open MPI is doing.

Even if you don't plan to adopt it, it might be instructive to write a =

It certainly looks like a dependency issue between the generated files, =

actually, (at least modern enough) autoreconf runs the aclocal twice.
Once before libtoolize call (do detect whether it should call the
libtoolize tool at all) and second time [1] after libtoolize to
incorporate the macros.

I'd like to say in advance that IMO this should be fixed in libtoolize,
somehow, reasoning follows.

- autoreconf is really generally believed to be the "tool #1" for
  regenerating GNU buildsystem .. if we don't take the 'gnulib' or others
  into account of course;  then however bootstrap comes and autoreconf
  -vfi should still be OK

- thus either libtool or autoreconf should be fixed, ..

- when libltdl is included into project as 'convenience' library, it is
  treated like "subproject".  Then running autoreconf from project's
  $(top_srcdir) treats subprojects independently by recursing down into
  subdirectory (in our case libltdl) and autoreconfing there.

  The child autoreconf does not expect that something defined in parent
  directory will touch subdirectories after successful autoreconf.

  When parent autoreconf finished with autoreconfing of subdirectory, it
  continues in cwd - and that includes running libtoolize; _however_, this
  second run of libtoolize from top-level overwrites the _common_ macros.
  Now, the macros are more recent than the "subdirectory thinks".

  After that ^^^, the aclocal tool is run in top-level directory - but it
  has no idea about recursing down into (otherwise independent)
  subdirectory.  So everything happens as expected, two separate
  directories were autoreconfed independently.

Yes, this work-arounds that.  Thanks!

Hmm, I think sharing the macros with top-level is clear trigger here.

Reproduced.  I'll try to make automatized reproducer and post later
possibly.

To make it clear:  The top-level libtoolize re-initializes the
sub-directory macros without runing autoreconf.  Makefile.in _is already_
generated (distributed via libtool) and put on place.  The Makefile.in
distributed with libtool contains:

  am__aclocal_m4_deps = $(top_srcdir)/../m4/libtool.m4 \
  >-------$(top_srcdir)/../m4/ltargz.m4 $(top_srcdir)/../m4/ltdl.m4 \
  >-------$(top_srcdir)/../m4/ltoptions.m4 \
  >-------$(top_srcdir)/../m4/ltsugar.m4 \
  >-------$(top_srcdir)/../m4/ltversion.m4 \
  >-------$(top_srcdir)/../m4/lt~obsolete.m4 $(top_srcdir)/configure.ac

Without regenerating Makefile.in, bad things happen if user has
non-default AC_CONFIG_MACRO_DIR.  Also, proposed fix [2] is kind of
related.

-------

For the solution, I was thinking about something like detecting whether
libtoolize is run from $(srcdir) or not.  Something like:

  --- a/libtoolize.in
  +++ b/libtoolize.in
  @@ -898,6 +898,8 @@ func_install_pkgltdl_files ()
       $require_ltdl_dir
       $require_ltdl_mode

  +    test '.' = "$ltdl_dir" || return
  +
       # Remove any lingering files that my have been installed by some
       # previous libtoolize release:
       $opt_force && for file in $all_pkgltdl_files; do

.. or turning maintainer mode on in libltdl?  Documenting autoreconf-ing by
hand in subdirectory is also an option (after top-dir is done) but that is
counter-intuitive without 'autoreconf --no-recursive'.

That all because it seems to me that hacking this in autoreconf is (a) imo
too difficult and (b) too late as libtool-2.4.4 is out.

incorporate the macros.

I'd like to say in advance that IMO this should be fixed in libtoolize,
somehow, reasoning follows.

- autoreconf is really generally believed to be the "tool #1" for
  regenerating GNU buildsystem .. if we don't take the 'gnulib' or others
  into account of course;  then however bootstrap comes and autoreconf
  -vfi should still be OK

- thus either libtool or autoreconf should be fixed, ..

- when libltdl is included into project as 'convenience' library, it is
  treated like "subproject".  Then running autoreconf from project's
  $(top_srcdir) treats subprojects independently by recursing down into
  subdirectory (in our case libltdl) and autoreconfing there.

  The child autoreconf does not expect that something defined in parent
  directory will touch subdirectories after successful autoreconf.

  When parent autoreconf finished with autoreconfing of subdirectory, it
  continues in cwd - and that includes running libtoolize; _however_, this
  second run of libtoolize from top-level overwrites the _common_ macros.
  Now, the macros are more recent than the "subdirectory thinks".

  After that ^^^, the aclocal tool is run in top-level directory - but it
  has no idea about recursing down into (otherwise independent)
  subdirectory.  So everything happens as expected, two separate
  directories were autoreconfed independently.

Yes, this work-arounds that.  Thanks!

Hmm, I think sharing the macros with top-level is clear trigger here.

Reproduced.  I'll try to make automatized reproducer and post later
possibly.

To make it clear:  The top-level libtoolize re-initializes the
sub-directory macros without runing autoreconf.  Makefile.in _is already_
generated (distributed via libtool) and put on place.  The Makefile.in
distributed with libtool contains:

  am__aclocal_m4_deps = $(top_srcdir)/../m4/libtool.m4 \
  >-------$(top_srcdir)/../m4/ltargz.m4 $(top_srcdir)/../m4/ltdl.m4 \
  >-------$(top_srcdir)/../m4/ltoptions.m4 \
  >-------$(top_srcdir)/../m4/ltsugar.m4 \
  >-------$(top_srcdir)/../m4/ltversion.m4 \
  >-------$(top_srcdir)/../m4/lt~obsolete.m4 $(top_srcdir)/configure.ac

Without regenerating Makefile.in, bad things happen if user has
non-default AC_CONFIG_MACRO_DIR.  Also, proposed fix [2] is kind of
related.

-------

For the solution, I was thinking about something like detecting whether
libtoolize is run from $(srcdir) or not.  Something like:

  --- a/libtoolize.in
  +++ b/libtoolize.in
  @@ -898,6 +898,8 @@ func_install_pkgltdl_files ()
       $require_ltdl_dir
       $require_ltdl_mode

  +    test '.' = "$ltdl_dir" || return
  +
       # Remove any lingering files that my have been installed by some
       # previous libtoolize release:
       $opt_force && for file in $all_pkgltdl_files; do

.. or turning maintainer mode on in libltdl?  Documenting autoreconf-ing by
hand in subdirectory is also an option (after top-dir is done) but that is
counter-intuitive without 'autoreconf --no-recursive'.

That all because it seems to me that hacking this in autoreconf is (a) imo
too difficult and (b) too late as libtool-2.4.4 is out.

Hi Pavel,

Not in the least, the issue is convoluted, and I'd rather have long and

That's good to know.  I stopped closely following autoconf development a
few years ago, and didn't realise this was finally cleaned up.  Some of
these corner case may be because of my slightly out of date view of how
these tools interact :-(

Not always.  There is the full subproject mode, but also recursive and
nonrecursive modes that hooks into the parent project's configure.ac =
(and
Makefile.am in the latter case).

Is it only subproject libltdl (the one with its own configure.ac) that
exhibits this bug?

Eventually (and by "eventually" I mean I've been planning for a long =
time,
but haven't got to it yet) I'd like to get rid of the whole concept of
carrying a local libltdl.  Libtool is now pervasive enough in the =
ecosystem,
that it would be massively more straight forward if libltdl were just =
treated
like any other dependency... i.e. if your project needs it, just install =
the
proper version on your system first.

We've long ignored the problem of what happens when linking, say, =
libm4.so
with an internal copy of libltdl.so into an application that also uses =
the
system libltdl.so, or worse wants to link with it's own subproject =
version.
I'm sure distros have to jump through some hoops to make all of these =
clients
simply agree on the system libltdl.so, which really is the only sane =
solution.
The various subproject modes are an outdated idea from 20 years ago when
libltdl didn't have any traction yet.

[[snip]]

I think I'll try to release Libtool 2.4.5 later today, and then hack all =
the
multi-mode libltdl subproject support out entirely for the next release, =
which
neatly sidesteps the trickle of bugs caused all the little subtle =
interactions
between the various generated files.

I bet this particular bug yes.  But that is something I can not say
surely.  Switching to LTDL_INIT([nonrecursive]) works fine for me.

TBH, this is something I have no strong opinion on.  Seems like there is
no big benefit at least for GNU/Linux.  Maybe going through some
obsoleting process could help .. but I need to study more to discuss.

Now that I think about it, why is it necessary to run aclocal just to
find out whether LT_INIT, AM_PROG_LIBTOOL or AC_PROG_LIBTOOL is invoked?
I know that for a full m4 --trace run, one needs to have some (possibly
outdated) versions of required macros available, but it's very easy to
work around that: see the implementation of `func_require_libtoolize` in
the libtool bootstrap script (my clean rewrite of the gnulib bootstrap
script).

Further, now that autoconf is actively maintained again, why do we have
a vestigial autoreconf and a whole zoo of autogen.sh and bootstrap scripts?
Wouldn't it make more sense to centralize and maintain all of this in the
one true autoreconf?  Merging my bootstrap script with the latest autoreconf
eliminates the spurious rerun of aclocal, and brings support for gettext,
gnulib and per-project customizations.

It doesn't seem like a great deal of work to translate 700 lines of perl
into shell, fold it into bootstrap, and ship the result as autoreconf in the
next release of Autoconf.  Then everyone can go back to running `autoreconf
-fvi` and be done with the whole mess of wrapper scripts...

Cheers,

Is it really true that Linux systems all install libltdl-devel by default t=
hese days?

Without it, Open MPI can't compile its libltdl support, which is pretty key=
.

I ask because most people will install a Linux distro and then go grab the =
latest Open MPI tarball and build it from source (because OMPI releases far=
 faster than distros, and we don't distribute binaries).

Plugins are pretty critical to Open MPI... that's why we embed libltdl.

It would be pretty bad for us if you prevent us from embedding libltdl.  We=
 would be very, very sad pandas.  :-(

To be clear...

I'd still really like to embed libltdl in some way in OMPI.

If it's a different way than we've been doing before, that's fine.

E.g., if you give me a simple procedure to follow instead of using the magi=
c m4 macros, that would also be fine.  I.e., something that would reduce yo=
ur support burden by making it less of a general case for everyone to use (=
i.e., reduce that steady trickle of bugs you mentioned).  I'd even be fine =
if the bulk of libltdl's configure.ac script moved into a .m4 that I could =
call from my own, top-level configure.m4 (and I could copy all the relevant=
 libltdl .m4 files into my own m4 macro directory).  That would be great/ea=
sy, for example.

...or any other solution that would be easy(ier) for you to keep maintainin=
g some form of libltdl embedding option.

Why to do this in the first place ?

At all, why to rely on shell scripting when Perl compiles on a gazillion of platforms and doesn't even require root privileges in order to be installed ? Furthermore, Perl is portable in the sense that properly compiled Perl tree can be moved to another location and it will still work - it is by design
