Hi.
I downloaded the native code example from the IBM site. Did exactly like
they did and boom it breaks. This is on Linux slackware 10.0using gcj
3.3.4.
Then I tried SWT 3 for GTK on linux. And this is what I get.
[francoish@cyberdeth:~/src/Java/native/Hello] gcj -fjni --main=Hello
--classpath=./swt.jar:./swt-pi.jar -o Hello Hello.java

I'm starting to think that this SWT + GCJ native compile is a fase and
doesn't really work. My hello world example looks like this :
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.RowLayout;
public class Hello {
public static void main(String[] args) {
Display display = new Display();
final Shell shell = new Shell(display);
RowLayout layout = new RowLayout();
layout.justify = true;
layout.pack = true;
shell.setLayout(layout);
shell.setText("Hello, World!");
Label label = new Label(shell, SWT.CENTER);
label.setText("Hello, World!");
shell.pack();
shell.open ();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep ();
}
display.dispose ();
}
}
Now when compiling this with java it works great but that is not what I
want. The thing is I get the same result on MacOS, so it isn't OS
specific. Please can someone throw me a friggen bone here.
Thanks
