In oder to create a simple opencv java project I folled this tutorial step by step but
when I run the associated exemple I get the folowwing error :
Exception in thread "main" java.lang.UnsatisfiedLinkError: no libopencv_java247 in java.library.path
EDIT
I read all similar questions and I try those solutions
--
-Djava.library.path=/home/noura/Desktop/opencv/build/lib/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/noura/Desktop/opencv/build/lib
but the problem is not solved
