In all of the recent releases (at least 0144 and on), I encounter an error
when trying to run any Processing applet in Eclipse that uses OpenGL.
Currently this is happening with the recent 0148 release. I am using OS X
10.5.4 on a MacBook Pro with an ATI x1600.

The source of the problem appears to be the native libraries that
opengl.jar references. I am using all .jars from 0148 (opengl.jar,
core.jar, jogl.jar) in my Java build path, but with the native library
location set to the ones inlcluded in 0148, I get an error and the applet
will not run. If I keep using all the same .jars, but set the native
library location to those that come with 0135, it works ok.

This code in an Eclipse project will reproduce the error:

import processing.core.*;
import processing.opengl.*;

public class EmptyApp extends PApplet
{
public void setup()
{
size(640,480,OPENGL);
}
}

Here is what it spits out into the console:

This is not a Processing bug, your classpath is messed up. The method
requestDisplay() no longer exists in release 0145 and later. This is the
sort of thing that you avoid by using the PDE but when using Eclipse,
you're on your own.

Hmmm...

Well, the error that you posted makes no sense (and references an older
jar), but I think there might be some validity to this issue.

Something has changed about the OpenGL configuration which prevents the old
methods of using Processing with Eclipse. I'm not saying this is a "bug"
per-se, but there is probably a new way of setting up Eclipse that we need
to discover.

I consistently get the following error with the files from 148 on OSX:

Sure enough... just needed to add "gluegen-rt.jar" ... Sorry for taking up
bug space Ben!!
