I'm doing OpenCv program in Java. This error keep popping up. 

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat()J

  • Share your code here – Onic Team Apr 21 '18 at 18:29
  • `public void processEvents() { for(Runnable event: eventQueue.poll()) { event.run(); } }` – Kantie Apr 23 '18 at 14:44
  • I'm doing HoughCircle. Actually the code is quite long The error come at line eventQueue.poll() – Kantie Apr 23 '18 at 14:46
  • Updated: my error is now `Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat(III)J` – Kantie Apr 23 '18 at 16:28
  • There is something wrong with second line here, and i have no idea what's wrong with that `byte [] data = ((DataBufferByte)rescaleimg.getRaster().getDataBuffer()).getData(); Mat mat = new Mat(rescaleimg.getHeight(), rescaleimg.getWidth(), CvType.CV_8UC1); mat.put(0, 0, data);` – Kantie Apr 23 '18 at 16:29
