reuse header and c file as library

I am using Nios II SBT Eclipse. I have couple of .c and .h files that i would like to use in a project. But when I trying to call the function in main program, it keep give me error of "undefined reference to: "function name"". I had include the header using# include. All the .c and .h file are placed in a folder in the same directory. Can someone help me with how to set up this folder as include library?

    Hi,

    Can someone help? I still cant solve the problem. Let say I had a header and a source file,

    ======= myfunc.h ============

    #ifndef _MYFUNC_H___

    # define _MYFUNC_H___

    # include <stdio.h>

    void funcCall();

    # endif

    ====== myfunc.c =============

    #include <stdio.h>

    # include "myfunc.h"

    void funcCall(){

    printf("Called funcCall");

    }

    They both are in a folder called "lib"

    Let say I created a new SBT project and add the source below:

    # include <stdio.h>

    # include "myfunc.h"

    int main(){

    printf("Hello,Its working!");

    funcCall();

    return 0;

    }

    The build result always says that undefined reference to funcCall()... What I have to do to successfully build this simple system?
