Unable to view images

I'm getting the following errors in vision.err

java.io.IOException: /linux/nativearm/ntcorejni.hash Resource not found

Also, my successes were using an old version of the software. This was the new one in master.

I'm able to reproduce that error on my end. I'll poke at it & see if I can find some relevant information.

It looks like the error is on line 17:

public class Main {
private static VisionProcessor vision;
(17) public static final NetworkTableInstance netTable = NetworkTableInstance.getDefault();
private static NetworkTable data;
private static CameraServer manager = CameraServer.getInstance();

I'm looking into that as well.

It looks like the error is that the java program can't find: /linux/nativearm/ntcorejni.hash

This does exist on my machine - but I don't know the syntax for how to change the runCameraVision script to be able to find it.

Created a branch, updates-to-build-gradle, that is at least pushing images to the network interface. I made two major changes. One in the build.grade file:

// old code:
// from (ntcoreUnzipLocation + "/linux/nativearm") {
from (ntcoreUnzipLocation + "/linux/raspbian") {

and in main.java:

public static void main(String[] args) {
// Loads our OpenCV library. This MUST be included
System.loadLibrary("opencv_java310");
//** System.loadLibrary("ntcore");

So it looks like I just need to figure out how to get the system.loadLibrary of ntcore working.
