打开Java 3.1.0 for Java java.lang.UnsatisfiedLinkError

Question

我从源文件安装了opencv 3.1.0并尝试了示例代码 http://answers.opencv.org/question/68037/opencv-3-java-face-recognition-example-requested/。

然而，

  CascadeClassifier faceDetector = new CascadeClassifier(
       "/usr/local/share/OpenCV/lbpcascades/lbpcascade_frontalface.xml"
  );

返回错误

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.opencv.objdetect.CascadeClassifier.CascadeClassifier_0(Ljava/lang/String;)J

我做

 System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

在CascadeClassifier之前

并且它不会返回任何错误（看起来）
