各位大牛好:
遇到一个棘手问题需要请教各位有opencv经验开发的大牛。
在centos6.5/opencv2.4.9/jdk1.7/cmake3.0环境下,编译opencv 并支持java模块,编译成功后,通过opencv编译后的build 生成的test jar文件测试。
cmake命令: cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=RELEASE -DBUILD_FAT_JAVA_LIB=ON ..
测试语句如下:
java -cp opencv-test.jar:../../lib/junit-4.11.jar -Djava.ext.dirs=/home/opencv/opencv_test/libs -Djava.library.path=/home/opencv/opencv-2.4.9/lib org.junit.runner.JUnitCore org.opencv.test.objdetect.CascadeClassifierTest
运行后,始终报异常,异常信息如下:
[root @localhost jar]# java -cp opencv-test.jar:../../lib/junit-4.11.jar -Djava.ext.dirs=/home/opencv/opencv_test/libs -Djava.library.path=/home/opencv/opencv-2.4.9/build2/lib org.junit.runner.JUnitCore org.opencv.test.objdetect.CascadeClassifierTest

There were 17 failures:

并且自己编写代码调用链接库也是报错:
下面粘出部分代码和报错信息:
System.out.println("\nRunning DetectFaceDemo");
// 导入opencv的库
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

System.out.println("opencv version: "+Core.VERSION);

CascadeClassifier faceDetectorAll = new CascadeClassifier();
报错信息:
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.opencv.objdetect.CascadeClassifier.CascadeClassifier_0()J

以上是请求帮助详细信息,还请各位大牛指点迷津,万分感谢。
