Beginner's error
Aug 27th, 2009, 8:45pm  
Hi, I am running the intro sketch from the openGL entry and I get this error:

Exception in thread "Animation Thread" java.lang.VerifyError: (class: processing/opengl/PGraphicsOpenGL, method: bindTexture signature: (Lprocessing/core/PImage;)V) Bad access to protected data
     at java.lang.Class.getDeclaredConstructors0(Native Method)

//
import processing.opengl.*;

float a;

void setup() {
 size(800, 600, OPENGL);
 fill(0, 153);
 noStroke();
}

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;
}

//

Any help would be much appreciated.  Average processing user but beginner at OpenGL and would like to learn.  Thanks in advance. Smiley

bindTexture?  PImage?  Those aren't even part of that code.  How odd.

Code works fine for me, for what it's worth.

I'd say make sure you don't have any other sketches running, but then I'd think you'd get a bootstrap error...

After I dragged
D:\processing\processing-1.0.6\libraries\opengl\src\processing\opengl\PGraphicsO
penGL.java
into the sketch, it ran without a problem.  It still doesn't work without it though.  I am probably missing something obvious...

D:/ ?   are you running this from a CD / other unwritable drive?  It's possible that it needs to be on your C:/ drive to properly import openGL automatically...

Doesnt need to be on C: got it on D: too but like BenHem said, is it on a cd or just a different partition?

Had the same error, and realised that I had copied ALL legacy processing libraries to the ~/Documents/Processing/libraries/ folder (as they used to be in the Processing application folder. The duplicate opengl/ folder caused the trouble.

So, by removing ~/Documents/Processing/libraries/opengl things started working again. (this being from the os X perspective, but I suspect it might be similar for windows too..)
