Description

The error message can be seen in one image.
image After I manually copied the libopencv_world.so.3.4 file over, the program ran normally.

However, the libopencv_world.so.3.4 file is already included in the jar package. Why wasn't the libopencv_world.so.3.4 file extracted to that directory, causing me to manually copy the file over when running the program?

I have tested all versions of javacpp, but this issue still remains unsolved. Is there any way to solve this problem?

Contributor guide

Research direction
Examine the javacpp library extraction mechanism to understand why libopencv world.so.3.4 is not automatically extracted. Check the jar contents and the native library loader configuration.
