Compiling a .dll in netbeans (Almost there)

Question

(I have the GNU g++ cygwin compile installed and selected to be used as C compiler in netbeans)
I have got so far but falling at the last hurdle.
I have modified a java wrapper so that I can put it in a package, I adjusted the code, compiled it, called javah on the source class using:
javah packagename.classname
which worked
I've then re-written the wrapper.c file so that it includes this new header file classname.h
I've re-written the methods so that they start with Java_packagename1_classname1_ (the way they appear in the header)
I've created a new C/C++ project in netbeans (Selected dynamic linked library in options)
I've added the exsisting classname.h files + Cdll.h file to the header files (both included in the wrapper.c)
Now I should be set to compile my wrapper.c into a .dll file
I press the build button and I get this:

Ok I'm still stuck here is my test code as simple as I can make it:
Main.java
package dlltestapp;
import java.util.logging.Level;
import java.util.logging.Logger;
public class Main {
    static {
         System.loadLibrary( "J-K8055-wrapper" );
    public static void main(String[] args) {
        USB_interface_K8055.JOpenDevice(0);
        USB_interface_K8055.JSetAllDigital();
        try {
            Thread.sleep(1000);
        } catch (InterruptedException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        USB_interface_K8055.JClearAllDigital();
        USB_interface_K8055.JCloseDevice();
}USB_interface_K8055.java
package dlltestapp;
public class USB_interface_K8055 {
public static native long JOpenDevice(long i);
public static native void JCloseDevice();
public static native void JSetAllDigital();
public static native void JClearAllDigital();
