Missing functions on Linux Amd64

[giles7777]

My calls to glGenBuffers are failing on an Amd 64 Linux box.   I check the function with gl.isFunctionAvailable which returns true, but then it dies on the actual call.  It runs fine on a windows and mac box.

JOGL 1.1.0-rc1
ATI Radeon X800 XT, GL_VERSION 2.0.6234
has GL_ARB_Vertex_buffer_object


Test code showing the issue.

import java.awt.*;
import java.awt.event.*;

import javax.media.opengl.*;
import com.sun.opengl.util.*;

public class Tester implements GLEventListener  {
  public static void main(String[] args) {
    Frame frame = new Frame("Gear Demo");
    GLCanvas canvas = new GLCanvas();

    canvas.addGLEventListener(new Tester());
    frame.add(canvas);
    frame.setSize(300, 300);
    frame.show();
  }

  public void init(GLAutoDrawable drawable) {
    // Use debug pipeline
    // drawable.setGL(new DebugGL(drawable.getGL()));

    GL gl = drawable.getGL();

    System.err.println("INIT GL IS: " + gl.getClass().getName());

    System.err.println("Chosen GLCapabilities: " + drawable.getChosenGLCapabilities());

    boolean funcAvailable = gl.isFunctionAvailable("glGenBuffers");

    System.out.println("function: " + funcAvailable);
    if (funcAvailable) {
        // Seems on some systems this still fails on the glGenBuffers call, so check
        try {
            int[] vbo_id_tmp = new int[1];
            gl.glGenBuffers(1, vbo_id_tmp, 0);

            System.out.println("Success!");
        } catch(Exception e) {
            System.out.println("VBO's reported but not really available");
        }
    }

  }

  public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) {
    GL gl = drawable.getGL();

    float h = (float)height / (float)width;

    gl.glMatrixMode(GL.GL_PROJECTION);

    System.err.println("GL_VENDOR: " + gl.glGetString(GL.GL_VENDOR));
    System.err.println("GL_RENDERER: " + gl.glGetString(GL.GL_RENDERER));
    System.err.println("GL_VERSION: " + gl.glGetString(GL.GL_VERSION));
    gl.glLoadIdentity();
    gl.glFrustum(-1.0f, 1.0f, -h, h, 5.0f, 60.0f);
    gl.glMatrixMode(GL.GL_MODELVIEW);
    gl.glLoadIdentity();
    gl.glTranslatef(0.0f, 0.0f, -40.0f);
  }

  public void display(GLAutoDrawable drawable) {
  }

  public void displayChanged(GLAutoDrawable drawable, boolean modeChanged, boolean deviceChanged) {}
}

Somebody recently reported that JOGL's "DRI hack" class isn't working properly with ATI's proprietary drivers. We're looking into this and hope to have a workaround sometime next week. For now please try checking out and building the JOGL source tree, and in the DRIHack.java class, just before the "if (driHackNeeded)" line, set "driHackNeeded = false;". Does that help?
