How to link standard library to a cross-compiler?

Question

I want to build xv6 on macOS, so I installed the cross-compiler toolchain i386-elf-gcc and i386-elf-gcc from a Homebrew Tap.

The problem is i386-elf-gcc cant link standard libraries while compiling. I tested on a simple c file, and got the following error.

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

int main(void) {
    printf("d\n");
    return 0;
}

Error:

> i386-elf-gcc --sysroot=usr/includes test.c
test.c:1:10: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
          ^~~~~~~~~
compilation terminated.

to resolve, you could try adding the newlib library and cross-compile it to your architecture. The following link says the freeware newlib can be used as source of the stdlib to compile all by yourself.

One problem is that the standard libraries provided with most software development tool suites arrive only in object form...
