Need help with strange ldd output

[Yann Dirson <ydirson@altern.org>]

I have compiled a package which contains the following shared lib:

/usr/lib/liballeg-3.9.33.so


I think there are a number of things which were done wrong here, and
would appreciate any hints.  Please CC me on reply, I'm not on
deb-dev.

When I link something with it I get in ldd's output:

        liballeg-3.9.33.so => /usr/lib/liballeg-3.9.33.so (0x40025000)
        libc.so.6 => /lib/libc.so.6 (0x400d6000)

This syntax confuses dpkg-shlibdeps (and dh_makeshlibs did not look at
the file either).  Did anyone already seen such a problem ?  Was the
lib erroneously built, or is it just a symlink missing (I tried to
symlink it to liballeg.so.3.9.33, with no changes.


Also linitian reports the lib does not contain PIC, although .o files
are built with -fPIC, and the lib is linked with -shared.  Only
suspect thing I found: a couple of .o files do not appear to have a
GOT, although they were compiled with -fPIC:


$ rm obj/unix/shared/alleg/lgfxdrv.o 
$ make obj/unix/shared/alleg/lgfxdrv.o 
gcc -DHAVE_CONFIG_H -Iinclude -Iinclude/allegro -I./include -I./include/allegro -I.  -I/usr/X11R6/include  -O3 -ffast-math -fomit-frame-pointer -Wall -fPIC -DALLEGRO_SHARED -c ./src/linux/lgfxdrv.c -o obj/unix/shared/alleg/lgfxdrv.o
$ objdump -x obj/unix/shared/alleg/lgfxdrv.o
