I downloaded the native code example from the IBM site. Did exactly like

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

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

as I've told you, for me compiling swt.jar didn't work (on windows).
on linux I've used libswt (http://libswt.sourceforge.net/).
on the other hand I frequently compile swt apps on windows using the
following distro http://thisiscool.com/gcc_mingw.htm#gcj34 and it works
like a charm, both on static and dynamic linking. It has build-in
support for swt3. An idea is to download the source code for thisiscool
distro (large file from same address) and recompile it on linux (the swt
part) if you're not happy with libswt's 2.1 version.
cheers,
Radu

Yeah.
I resorted to using libswt. It works great on Linux, what with GTK being
on there et al, but that still doesn't fix the MacOS thingy. I did however
get some ideas from the project and I'm thinking that I might do the same
thing with SWT 3 on MacOS, ie. take the SWT carbon source code and
recompile it into a .dylib or maybe even a .a.
It will take a bit of work to get it done. Might just use a Makefile to do
it. Seems like the easiest solution.
Thanks a ton. You really helped and given me some ideas to get around this
problem.
Thanks.
