Eclipse & OpenGL on Mac OS X Exception in thread "Animation Thread"

in Integration and Hardware • 2 years ago

Hello,

I have been banging my head in the walls for a quite some time now, but I seriously do not know what I am doing wrong here. I have googled the problem for some time and now I get more and more confused. Here is the problem; I am trying simply to run the example from the OpenGl reference http://processing.org/reference/libraries/opengl/, with Eclipse and I get nothing but errors.

I basically add/import the core.jar and opengl.jar to the project path, but I get a warning at the import processing.opengl.*;

saying that the library is never used (???) - its very very strange, because it is there, and i can see it...

If i render this with the P3D mode parameter, it works fine, but for OpenGL its a mystery.

import processing.core.*;

import processing.opengl.*;

public class testingOpenGL extends PApplet {

//private static final long serialVersionUID = 1L;

float a;

public void setup() {

size(800, 600, OPENGL);

fill(0, 153);

noStroke();

}

public void draw() {

background(255);

translate((width/2), (height/2));

rotateX(a);

rotateY(a*2);

rect(-200, -200, 400, 400);

rotateX(PI/2);

rect(-200, -200, 400, 400);

a += 0.01;

}

When I try to export/compile this piece of code, i get the following errors:

Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: javax/media/opengl/glu/GLUtessellatorCallback

Then I google this error:

javax/media/opengl/glu/GLUtessellatorCallback

and there are tons of suggestions, which I have already tried out, but none of them work.

1.) Adding the "opengl" classpath to the VM arguments - did that, but its not working

2.) Suggestions about adding jogl.jar to the project folder - already done this by adding the opengl.jar to the project folder, because it already contains the jogl.jar

3.) Browsed the old forum and triend with different MODE parameters, but NOTHING works.

I am running OS X 10.6.4
with Eclipse 3.6.1

Java SE 1.6
JOGL libraries supplied with the opengl package
Processing 1.2.1.

Any suggestions, solutions, thoughts? I would really appreciate this....

I never tried Processing in Eclipse (do you use the Processing plugin?), even less on Mac, but in general, in this IDE, you have to do more than adding a jar to a path. You are supposed to import it in the project: go to the project properties, build section, and in one tab, you will get a dialog to add external jars to the project. Add core.jar (if not done already), and the OpenGL jars.
If you did that already, I don't know what is missing...

PS.: Processing might need the OpenGL import (or requires it when it detect the mode in the size() call), but Eclipse doesn't (I think) because PGraphicsOpenGL class is loaded dynamically, with reflection. At least, it doesn't detect a direct use of this class, that's why it marks it as unused.

Hi - thanks for the reply!

I am not sure what you mean with plugin, but I use processing as a library in Eclipse, installed with the intructions from the Processing website http://processing.org/learning/eclipse/. I dont use the processing PDE/sketches - everything I do is with the Eclipse IDE. I have some basic and simple projects working, such as the "helloworld", and also the "Stripe" example from the same URL mentioned above.

The main reason I need Processing is basically to load a Quicktime movie... but even with THIS I am having troubles. See this post: http://forum.processing.org/#Topic/25080000000324065 - the frames are delayed. So initially I thought that it had something to do with the OpenGL / Java Applet - cause I guess somehow Java uses OpenGL etc... and i tried implementing the simple example from the Processing website, and I stumbled upon the aforementioned problem.

What you write about importing the core.jar and the OpenGL jars, I already done this - and said "Add to Build Path".. and I even tried to write the direct path to the PGraphicsOpenGL in multiple ways like:

import processing.opengl.PGraphicsOpenGL.TessCallback;

import processing.opengl.PGraphicsOpenGL.TessCallback.*;

import processing.opengl.PGraphicsOpenGL.*;

import processing.opengl.*;

Everything looks like it is located in the Java Build Path... so to me, this is utterly and completely very very strange!

In any case, today I got a different error.... and here it is:

I have to Google this, and see if I can solve it. I will get back to the forum if I solve anything... but in any case - anyone reading this having the similar problem please do not hesitate to contact me through here or private message.

Thanks!

Have you imported the native OpenGL libraries? They are needed to run and have to be linked with the OpenGL jars…

A good tutorial can be found here:

Omg!! This has saved my life!! Thank you sooooo much. After following the steps from that page, i finally made this simple OpenGl example to work with Eclipse. I guess importing the jnlilibs files made the trick...

Anyways the weird thing about it is that after making the exporting the example in an Applet my editior is still giving me the warning of "The import processing.opengl is never used"... but it works because it uses the function calls rotate/translate etc... weird.... but it WORKS!!! :-) THANKS!!!!
