[Bug binutils/2676] New: ld and shared libraries

[Philippe dot Vouters at laposte dot net]

I noticed that, instead of inserting a soft shared library link inside the
executable, Linux linker (ld) inserts the resolved shared library name. This
forces programs to be relinked each time an actual shared library name has
changed, after any upgrade either using yum or distribution upgrades. This
prevents me from using programs which are shipped within an RPM and are linked
under FC4, such as Openwengoo among some. Providing ldd would show a soft link,
this would enable to more easily distribute executable programs.

HP Unices (HP-UX and Tru64) linkers only inserts in the programs the soft link,
enabling to easily install library patches with a different extension without
having to relink all programs.

So I'd like to report this wish to ld and dl (dynamic loader) maintainers so
that soft shared libraries links are used instead.

Reproducer:

address@hidden ~]$ cat hello.c
#include <stdio.h>
int main(){
printf("Hello!\n");
return 1;
}
address@hidden ~]$ cc -c  hello.c
address@hidden ~]$ cc -o hello -lc hello.o
address@hidden ~]$ ldd hello
        linux-gate.so.1 =>  (0x00a1b000)
        libc.so.6 => /lib/libc.so.6 (0x001a6000)
        /lib/ld-linux.so.2 (0x0018b000)
