Libtool and staged installs (-L$install-libdir before -L$staged-install-libdir)

[Ulrik Petersen]

Hello,

I'm using a fairly recent CVS snapshot of libtool (April 25, 2003),
along with a CVS snapshot of autoconf from the same day, and Automake
1.7.4.

Automake allows "staged installs".  A description of how to do "staged
installs" could be as follows (taking my Emdros software package as an
example):

-- example description begins --
The following assumes that you want to install in /opt/Emdros and build
the package in /var/tmp/Emdros before installing.

1. ./configure --prefix=/opt/EmdrosPQ
2. make
3. mkdir /tmp/EmdrosPQ
4. make DESTDIR=/tmp/EmdrosPQ install
5. build package in /tmp/EmdrosPQ for installation in /opt/EmdrosPQ
-- example description ends --

When running

$ make DESTDIR=/tmp/EmdrosPQ install

libtool relinks the shared libraries.  Below I have reproduced four
lines of the output from this command, with most spaces converted to
newlines + indentation.  The lines are numbered.


1. /bin/bash ../libtool --mode=install .././install-sh -c  libmql.la
/tmp/EmdrosPQ/opt/EmdrosPQ/lib/emdros/libmql.la

2. libtool: install: warning: relinking `libmql.la'

3. (cd /var/tmp/emdros-1.1.11.pre31/MQL; /bin/bash ../libtool

    -L/tmp/EmdrosPQ/opt/EmdrosPQ/lib/emdros
    -lpgemdf
    -lemdf  


Problem is, libtool (in line 4.) adds a -L/opt/EmdrosPQ/lib/emdros
switch before the -L/tmp/EmdrosPQ/opt/EmdrosPQ/lib/emdros switch:

    -L/opt/EmdrosPQ/lib/emdros
    -L/tmp/EmdrosPQ/opt/EmdrosPQ/lib/emdros

(see the last four "lines" of line 4.)

This means that if there was an old version of the package lying around
in the installation directory (/opt/EmdrosPQ/lib/emdros), the old
versions of any dependency-libraries (in this case -lpgemdf and -lemdf)
are linked against rather than the ones in 

    -L/tmp/EmdrosPQ/opt/EmdrosPQ/lib/emdros

I hope you will take the time to fix this, if you agree with me that it
is a bug.  Perhaps it is automake that is at fault.

Ulrik Petersen
