relocation R_X86_64_32S against `.data' can not be used when making a shared object; recompile with -fPIC with gcc

Question

When I compile print.s using gcc I get the following error:

/usr/bin/ld: /tmp/cc45uyZj.o: relocation R_X86_64_32S against `.data' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status

1. I tried the same in another linux distribution and it worked perfectly.

2. Adding -fPIC doesn't help. Nor does apt-get update.

3. if you want to see the code: https://github.com/NEGU93/Compilation.git inside the Practice > Part1. Of course is the file print.s (btw. all the .s files have similar errors when I do gcc).

I guess something is missing in the Kali distro but I don't know what can it be.

Answer 1

It seems that your distro enables -pie by default (check gcc -v output) but your assembly is not position-independent. Try compiling a sample .c file under -fPIC and see how it generates calls. In your case it should be

call    printf@PLT

or you can try compiling with gcc -no-pie.

Answer 2

I get the same error as you when trying to link some object files compiled with clang and some with gcc. I guess these two compilers have different default settings regarding whether to produce position independent code.

So make sure you're not accidentally using the wrong compiler on part of your project.
