Próbuję skompilować i uruchomić prosty program „Hello World” w C i otrzymuję dziwny błąd w wielu definicjach niektórych funkcji C stdlib

Plik .c to:

<code>#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv) {

  printf("hello world\n");
  return 0;
}
</code>

Polecenia, których używam do kompilacji i tworzenia pliku wykonywalnego to:

<code>gcc -Werror -Wall src/main.c -o bin/m.o
gcc -Werror -Wall bin/m.o -o bin/m
</code>

Część kompilacji idzie dobrze, ale w drugim poleceniu, w którym wywołuję linker GCC, aby utworzyć plik wykonywalny, otrzymuję następujące błędy:

tak przy okazji, kiedy uruchamiam plik m.o z prefiksem wykonującym bash, działa to dobrze

nigdy nie programowałem w C ani nic, staram się zacząć, ale to mnie powstrzymuje
