You try to link your app against OpenCV build for desktop. You need to build OpenCV for ARM manually by this tutorial and link app against it.

Hi, thanks, have done that. But now I am getting another error:

/usr/local/lib/libopencv_highgui.so: undefined reference to `[email protected]_2.15'

Do You have an idea what can it be?
