Hi guys,
I've compiled arm-linux-gcj (gcc 4.3.0) with GTK+ AWT peers and now I would like to test a simple graphical application on my embedded box (PXA270, 128MB Ram, with LCD monitor).
Here is the code:
import javax.swing.*;
public class SimpleFrame {
public static void main(String args[]) {
JFrame f = new JFrame("Simple Frame");
f.setSize(200,100);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
}
}
I moved libgtkpeer.so library to the filesystem of embedded box and all the libraries required by libgtkpeer.so. I've taken these libraries from arm fedora rpms (
http://ftp.linux.org.uk/pub/linux/arm/fedora/pub/fedora/linux/releases/8/Everything/arm/os/Packages/).

I see that libgtkpeer is using libX11, is this the best choice for an embedded system? Would DirectFB be an alternative? Is there any way to build GTK+ AWT peer for DirectFB?
However I'm getting the following error when I try to run on my embedded box SimpleFrame compiled with gcj:
Warning: Out of Memory! Returning NIL!
I have like 120 MB of free ram when I try to do this.
Using "top" I see that SimpleFrame eats all the ram after loading all the needed libraries (I can see that from strace log).
Do I need to start the X11 server before running the application or do I need any other libraries to run a graphical application from a box without any windowing system?
Can anyone test which is the RAM footprint of SimpleFrame compiled with gcj and GTK+ AWT peers running on an arm box?
I feel like I'm missing something between gtk/glib layer and framebuffer, would anyone clarify this please?
Thank you,
Francesco
