[gl4java-usergroup] GL4Java + Linux +Nvidia crash

[<szt...@ya...>]

Hi,
 I just started to leard openGL with famous GL4Java library and got
some problems which I'm not able to solve by mylsef.
 My OS configuration is:
   Linux Debian 3.0, GL4Java 2.8.2.0, j2sdk1.4.1 Blackdown.org, Nvidia
GForce2 drivers from nvidia.com(games are working ok, so driver works).

 I composed this simple program below from demos examples (this is
demos/ronsDemos/animApplet.skel based). As you can see it does nothing
except trying to run few gl commands on animation thread. Once i run it
it crashes after openning window with message:
----------------------------
init(): X$myappletCanvas[canvas0,4,20,42x29]

An unexpected exception has been detected in native code outside the
VM.
Unexpected Signal : 11 occurred at PC=0x4C97E188

 I have seen some threads on this forum mentioning similar problems,
but answers were not enough detailed for me to be helpfull (I'm pretty
new Linux user).

  regards,

This is my problematic code:

public class X extends Frame
{
    myappletCanvas canvas = null;
	public static void main(String [] ar)
	{
		X x = new X();
		x.init();
		x.setVisible(true);
		x.start();
	};

	public void init()
	{
        Dimension d = getSize();
        setLayout(new BorderLayout());
        canvas = new myappletCanvas(d.width, d.height);
        add("Center", canvas);
	}

    public void start()
    {
        canvas.start();
    }
    public void stop()
    {
        canvas.stop();
    }
    public void destroy()
    {
        canvas.stop();
        canvas.destroy();
    }
    private class myappletCanvas extends GLAnimCanvas
    {
        public myappletCanvas(int w, int h)
        {
            super(w, h);
            GLContext.gljNativeDebug = false;
            GLContext.gljClassDebug = false;
            setAnimateFps(60.0);
        }

        public void preInit()
        {
            doubleBuffer = true;
            stereoView = false;
        }

        public void init()
        {
            System.out.println("init(): " + this);
            reshape(getSize().width, getSize().height);
            glj.gljCheckGL();
        }

        public void destroy()
        {
            System.out.println("destroy(): " + this);
            cvsDispose();
        }
    
        public void reshape(int width, int height)
        {
            gl.glViewport(0,0,width,height);
        }

        public void display()
        {
            if (glj.gljMakeCurrent(true) == false) return;
            glj.gljSwap();
            glj.gljCheckGL();
            glj.gljFree();
            if (!isSuspended()) repaint();  // Animate at full speed.
        }
    }
}
