awt problem on darwin

[Andreas Tobler <toa at pop dot agri dot ch>]

Hello,

could anyone may explain what's going wrong here?
I'd like to run a simple awt program on darwin. I have both Xservers 
running, the native OS-X and Xdarwin. On both the same error.
Is it simply not possible right now due to the config?

Any explanation is highly appreciated.

Thanks

Andreas

The config is:

Configured with: /Volumes/xufs/gccsrc/gcc/configure 
--prefix=/Volumes/reserved1/gcctmp --enable-languages=c,c++,java 
--enable-libgcj --enable-sjlj-exceptions --disable-threads 
--disable-java-gc --disable-shared
Thread model: single
gcc version 3.2 20020522 (experimental)

The code I want to run:

-----
import java.awt.*;

public class CGUI_Example extends Frame
{
CGUI_Example(String title)
         {
                 super(title);
                 Button first = new Button("First");
                 Button and = new Button("and");
                 Button second = new Button("Second");
                 setLayout(new FlowLayout());
                 add (first);
                 add(and);
                 add(second);
         }
public static void main(String[] args)
         {
         CGUI_Example Window =
                 new CGUI_Example("First GUI-App");
                 Window.pack();
                 Window.show();
         }
}
-----

I compile it with

gcj -ldl -o CGUI_Example CGUI_Example.java --main=CGUI_Example

I then try to run it with ./CGUI_Example

and get the following:

[titanium:~/tst] andreast% ./CGUI_Example
returned
end
Exception in thread "main"

Here it hangs.

Running the app with gdb produces the following output:

Starting program: /Users/andreast/tst/CGUI_Example
[Switching to thread 1 (process 2315 thread 0x1503)]
Reading symbols for shared libraries . done
returned
end
