reuse header and c file as 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?
