should libtool --relink expand lib*.la files before -L options?

[Mark Wright]

Hi,

In the libtool 2.2.4 relink command below, the ../../taglib/libtag.la
refers to a libtag.so library in the build directory.  I'm, sorry about
the zillion compiler options, however I think only the -L options,
the ../../taglib/libtag.la and its corresponding
-L/var/tmp/pkgbuild-mwright/FOSStaglib-1.5.0-build/opt/foss/lib -ltag
options are relevant.

My hopefully simple question is: is there some way to persuade
libtool/autotools to look for the libtag.so shared library first in
/var/tmp/pkgbuild-mwright/FOSStaglib-1.5.0-build/opt/foss/lib/libtag.so.1.5.0?

As in, I was wondering if libtool should expand the:

../../taglib/libtag.la

into:

-L/var/tmp/pkgbuild-mwright/FOSStaglib-1.5.0-build/opt/foss/lib -ltag

before the other -L options?

As instead what happens is it finds an old, incompatible one in
/usr/lib/libtag.so.1.4.0, which causes the unresolved symbol errors.

In the Makefile.am it just does:

libtag_c_la_LIBADD = ../../taglib/libtag.la

This is Solaris 10u5, Sun Studio 12, libtool 2.2.4, KDE 4 project.

So this is libtool 2.2.4 finding the wrong library in /usr/lib/libtag.so.1.4.0:

And this is how I would like libtool to link it, is there some
option for libtool 2.2.4 to move the:

-L/var/tmp/pkgbuild-mwright/FOSStaglib-1.5.0-build/opt/foss/lib -ltag 

first, before the -L options, like the following link command that works:

Some other changes I made in the above link line:

-no-undefined changed to -z defs
-version-info dropped
passed all the other options to CC.

The rpath is OK with my manual link line, as the libtag.so and
libtag_c.so shared libraries will be installed in /opt/foss/lib:
