My C compiler gcc is returned a reference error

Question

I tried compiling my program named 1-print_rev_recursion.c using this command gcc -o 1-print_rev_recursion.c recursion.o

#include "main.h"
#include "main.c"
/**
  * _print_rev_recursion - Print a string in reverse
  * @s: the string to reverse
  *
  * Return: void.
  */
void _print_rev_recursion(char *s)
{
        if (*s == '\0')
        {
                return;
        }

        s++;
        _print_rev_recursion(s);
        s--;
        _putchar(*s);
}

Here's my file main.c

#include <unistd.h>

int _putchar(char c)

And my header file main.h

But I got this error
