I am trying to call OpenCV library to do image processing in real time for a java camera application. below is the error log. Could this be a problem with my CMakeLists.txt file? Note that the program was working before I added 2 functions to the native-lib.cpp file.

Tetragramm Edit: Snipped the giant wall of log and added some spaces. I think I kept the important bits.

This error has happened when JNI have not including OpenCV lib.
