Let's say you have object file print_hello.a and a header print_hello.h. To be more precise let's create print_hello.a:

print_hello.h

#ifndef __PRINT_HELLO_
#define __PRINT_HELLO_

void print_hello();

#endif /* __PRINT_HELLO__ */

print_hello.c

#include <stdio.h>
#include "print_hello.h"

void print_hello() {
    printf("Hello!\n");
}

Compile it with

$ gcc -c print_hello.c -o print_hello.a

Now we need to add this to Eclipse. Create a project let's call it example. Create a example.c in which you will call print_hello

#include "print_hello.h"

int main() {
    print_hello();
}

Now we need to link it to the print_hello.a. Right-click on project and choose Properties. Go to the C/C++ Build -> Settings -> GCC C Linker -> Miscellaneous. In the Other objects click on add button and choose the path to the print_hello.a. Also add path to .h file in GCC C Compiler -> Includes. Build and run you project, it should output
