rpath problem.

[Jean-Paul CHAPUT]

Hi Mr Libtool,


I'm managing a project for wich we uses libtool (& all others autotools)
and I'm encountering a problem with rpath.

To do our development we have adopted the following architecture :

1. - Stables version of libraries resides in a shared directory.
     Says : /asim/project/lib holding
              libA.so.1.0.0 (+.la)
              libB.so.1.0.0 (+.la)
              libC.so.1.0.0 (+.la)
     "C" library depends on "B" and so "B" on "A".

2. - Unstables versions resides in a directory in the developper
     Account. Says : $HOME_B/project/lib holding
                       libB.so.1.0.0 (+.la)

3. - At link time Mr B. wants to use is own version of the "B" library,
     but the stable version of the "A" and "C" libraries. So he writes
     a line like this :

       ... -L$HOME/project/lib -L/asim/project/lib -lC -lB -lA

     In the hope that the first library path to be taken into account
     would be is personal one. But what seems to happens is that the
     rpath taken from "libC.la" overrides the one given in the command
     line and the "B" library which is choosen is the one from
     /asim/project/lib and not from the developper's library.

I've made a quick patch to overcome this problem, but I don't think it's
very clean and it mades two checks from the testsuite to fail. I join
the patch to this mail.

I uses libtool 1.5.6 from a Fedora Core 2 distribution with all updates
applied.


Thanks in advance.
