java Opencv unsatisfiedLinkError，本地库被加载

Question

I am trying to run some program on opencv, but I am getting this error:

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

I have already loaded the library, libopencv_java310.so by using this code:

System.loadLibrary(Core.NATIVE_LIBRARY_NAME);  

I have also added the path to the native library.

I have searched a lot on the internet, but the only reason this error comes, is due to native library is not loaded. What could be the other reason of getting this error.

Can anyone help....! Any help will be appreciated.

Answer 1

you might move your System.loadLibrary(Core.NATIVE_LIBRARY_NAME); to a static block so the dll gets loaded before any instruction of opencv .
