[Message part 1 (text/plain, inline)]

OK - it took awhile to understand this test - and I think it does indicate
a bug.

If I understand the test it is expecting the directory
addrunpath=`pwd`/foobar to be added to the .la file (and now I understand
the name of the test :)) -- tests/runpath-in-lalib.at

I expect this is to 'happen' with this statement

AT_CHECK([$LIBTOOL --mode=link $CC $CFLAGS $LDFLAGS -o liba.la a.lo -rpath
$libdir -R$addrunpath],
         [], [ignore], [ignore])

At the end of the test - this is the contents of the .la files regarding
libraries:
root <at> x064:[/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070]tail
-3 liba.la

# Directory that this library needs to be installed in:
libdir='/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070/inst/lib'

root <at> x064:[/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070]tail
-3 libb.la
# Directory that this library needs to be installed in:
libdir='/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070/inst/lib'
relink_command="(cd
/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070; /bin/sh
\"/data/prj/gnu/libtool/libtool-2.4.6/libtool\"  --mode=relink cc -O2
-qlanglvl=extc99 -o libb.la b.lo -rpath
/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070/inst/lib liba.la
@inst_prefix_dir@)"

Looking at the .so.0 files though...

root <at> x064:[/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070]dump
-H .libs/liba.so.0 | tail -3
                        ***Import File Strings***
INDEX  PATH                          BASE
MEMBER
0
/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070/foobar:/usr/vac/lib:/usr/lib:/lib


root <at> x064:[/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070]dump
-H .libs/libb.so.0 | tail -4
                        ***Import File Strings***
INDEX  PATH                          BASE

/data/prj/gnu/libtool/libtool-2.4.6/tests/testsuite.dir/070/inst/lib:/usr/vac/lib:/usr/lib:/lib

1                                    liba.a
liba.so.0

We see that .../foobar has been added to the internal LIBPATH variable.

I am a bit surprised by this because -R is suppossed to be a NULL op unless
the -bsvr4 flag is also specified - maybe that is also heppening in the
background - will look more carefully for that.

In any case, .../foobar is getting added to the shared object, but not the
.la text.

I have no clue where to look beyond this - hints/patch is welcome!

Michael
