javax.media.opengl.glu.GLU.gluNewTess()Ljavax/media/opengl/glu/GLUtessellator;

in Core Library Questions • 1 year ago

Has anyone seen this error before? I'm running OSX 10.7.4 and Processing 2.0b2. I get this error on any of the examples included with processing. I've also tried completely removing the installation and deleted the Processing folder in ~/Documents.

I haven't seen this error. I tested 2.0b2 on a OSX 10.7.4 machine. Do you get this error even with sketches that don't use either P2D or P3D.

That looks like what happens when another library (or your class path on your system) has embedded an old version of the OpenGL library, somehow overriding the built-in version that comes with Processing.

I was able to resolve the error by moving the GL files in the /Library/Java/Extensions folder to another location, thereby disabling them from being loaded instead of the Processing GL libraries.

The files were:

/Library/Java/Extensions/jogl.jar

/Library/Java/Extensions/gluegen-rt.jar

I simply moved those files into a folder called "backup" that I created in the same directory. Processing then ran as expected. I'm not sure the effect with will have on other Java applications, however.
