Sound library does not work in Eclipse

SichaoSong

Hi all,

I have got stuck by this trouble. I am now using Eclipse to write the programs of Processing, and I kept having troubles. The latest one I am facing is regarding the Sound library. I created a SinOsc object and use

sine = new SinOsc(this);

to initialise a new object. It works fine in Processing, but when I run it in Eclipse, the error messages pop out:

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: no MethClaInterface in java.library.path

Here is the whole code:

import processing.core.PApplet;
import processing.sound.*;

public class SoundExperiment extends PApplet {
    SinOsc sine; 
    
    public void settings(){
        size(600,600);
    }
    
    public void setup(){
        sine = new SinOsc(this);
        sine.play();
    }
    
    public void draw(){
        
    }

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        PApplet.main("SoundExperiment");
    }
}

Thank you!!
