How do I go about installing grip on the raspberry pi 2?

[LTGLambChops]

To start off here are the specs of the situation:
-GRIP 1.3.0rev2
-JDK1.8.0_73 (on the Pi, u74 on my laptop)
-OpenCV has been compiled and installed
-Python 2.7
-Python 3.4
-FFMPEG

Supposedly GRIP requires OpenCV or some other libraries not mentioned on GitHub, but every time we try to run GRIP on the raspberry pi we get a missing ntcore error from GRIP during initialization (about 20-30 seconds into the starting process).

Any steps on how other teams managed to install GRIP to their pi could benefit us, as GitHub (https://github.com/WPIRoboticsProjects/GRIP/wiki/Running-GRIP-on-a-Raspberry-Pi-2) has not been very successful for us.

Thanks, ahead of time.

Have you tried asking around the gitter chat (https://gitter.im/WPIRoboticsProjects/GRIP)? I don't personally know the answer, but a lot of people have had pi-related problems solved there.

I did find out how to get opencv installed on my raspberry pi, but I'm receving a new error - I will head over to the gitter chat after this post.

My fix to install OpenCV: "sudo apt-get install libopencv-dev"

I guess there is an issue with the libstdc++.so.6 with the current grip 1.3.0rc2 version or something. Also, it's straight out of jdk 8 throwing this exception specifically. --To Gitter!

Note: I will continue the updates on this thread as my problems are resolved, cheers!

I just got it working but I'm no expert. I started over and followed the wiki step by step. I installed the mjpg streamer and use a lifecam usb camera. I made sure to use only grip 1.2.0 version program and jar files. I made sure the deploy directory was /home/pi/code/grip and that I created that directory before deploying it.
