Failure to link multiple libraries.

[Roger Leigh]

I have two shared libraries, each made in a separate subdirectory.
Both are made with automake and libtool.

One library depends on the other, and I've used

libgimpprintui_la_LIBADD = $(GIMPPRINT_UI_LIBDEPS)

to indicate this ($(GIMPPRINT_UI_LIBDEPS) includes
$(top_builddir)/src/main/libgimpprint.la).

This seems to work when building, although libgimpprintui has the path
to the build tree libgimpprint.so hard-coded in.  However, when I
install, all libgimpprintui-using binaries are relinked incorrectly,
so that they now use *two* binary-incompatible libgimpprint.so's:

libtool: install: warning: relinking `libgimpprintui.la'

(cd /home/roger/gimp-print/current/src/libgimpprintui; /bin/sh
../../libtool --mode=relink gcc -Wall -Wcast-align -Wstrict-prototypes
-Wmissing-prototypes -Wmissing-declarations -Wnested-externs
-Wwrite-strings -pedantic -I../../include -I../../include -I../../intl
-g -O2 -o libgimpprintui.la -rpath /usr/local/lib -release 4.3.7
-rpath /usr/local/lib panel.lo plist.lo ui-utils.lo

-L/tmp/inst/usr/local/lib -lgimpprint -L/usr/X11R6/lib
                          ^^^^^^^^^^^ why!!!

-L/tmp/inst/usr/lib -lgtk -lgdk -lgmodule -lglib -ldl -lXi -lXext
-lX11 -lm -Wl,-soname -Wl,libgimpprintui-4.3.7.so -o
.libs/libgimpprintui-4.3.7.so


$ ldd /usr/lib/libgimpprintui.so | grep libgimpprint
        libgimpprint.so.1 => /usr/lib/libgimpprint.so.1 (0x40028000)

address@hidden:/usr/lib/gimp/1.2/plug-ins$ ldd print  | grep libgimpprint
        libgimpprintui-4.3.7.so => /usr/lib/libgimpprintui-4.3.7.so (0x4007a000)
        libgimpprint-4.3.7.so => /usr/lib/libgimpprint-4.3.7.so (0x4008f000)
        libgimpprint.so.1 => /usr/lib/libgimpprint.so.1 (0x40574000)
address@hidden:/usr/lib/gimp/1.2/plug-ins$

The installed version of libgimpprint (libgimpprint.so.1.1.0 is linked
to libgimpprint.so.1), but the development version is versioned with
-release, and called libgimpprint-4.2.7.so.  Somehow, *both* versions
are getting linked in...  In the above example, I'm installing into a
DESTDIR.


I think a problem similar to this has been posted before to the list,
but I'm not sure this is the same issue.  I'm using libtool 4.2.3
(Debian unstable).  Is there a way around this problem?


Thanks,
Roger
