relocation problem

[Dzianis Barzakouski <barzakouski@xxxxxxxxxxxxxx>]

Hi,

I am trying to compile following code:

===lib.c====
extern int foo();

int bar()
{
    int j = foo();
    return j;
}
==========

===add.c===
static int i = 0;

int foo()
{
    __asm__("mov 42, %ax");
    __asm__("mov %ax, i");
    return i;
}
==========

gcc -fPIC -c -o lib.o lib.c
gcc -fPIC -c -o add.o add.c
gcc -shared lib.o add.o -o lib.so
/usr/bin/ld: add.o: relocation R_X86_64_32S against `a local symbol'
can not be used when making a shared object; recompile with -fPIC

I thought that is due static declaration but it removing don't solves
the problem. Is this expected behavior? If yes, can somebody explain?

Thanks,
Dzianis
