Can't create Frame object with gcc 3.2

Mon Nov 4 00:04:00 GMT 2002

Hello,
I am trying to compile and execute a small Java program using gcc 3.2.
This program (see below) just creates a Frame object and displays it.
When executing the program, either as a "standalone" executable or
through gij, then an exception java.awt.AWTError is raised.
Am I doing something wrong ?
Thanks in advance for any help,
Pierre

import java.awt.*;
public class TestFrame {
 public static void main(String[] argv) {
 Frame window = new Frame("TestFrame");
 window.setSize(512, 512);
 window.show();
 }
}

$ export PATH=/opt/gnu/java/bin:$PATH
$ export LD_LIBRARY_PATH=/opt/gnu/java/lib
$ gcj -C TestFrame.java
$ gcj -c TestFrame.class
$ gcj -o TestFrame --main=TestFrame TestFrame.o

$ ./TestFrame
returned
end
