GRIP Deploy Not Working
Hello everyone,

My team is trying to use GRIP on our Raspberry Pi 3 to run the vision code for our robot. Each time we deploy, we keep recieving an error that I have pasted at the bottom of this post. We've followed all of the steps at https://github.com/WPIRoboticsProjec...Raspberry-Pi-2 and have copied over the shared libraries. Each time we deploy, it keeps saying that it can't instantiate files related to network tables. I'm sure that we have placed the shared libraries in the right folders and have deployed the project to the right folder, so do you know why this isn't working? I'm using GRIP 1.2 on Raspbian.

Thanks,

Jonathan

Re: GRIP Deploy Not Working
I had this issue too. The Deploy page won't properly run GRIP, you have to use a custom script to do it. On this page it has this command:
Code:
$ env LD_LIBRARY_PATH=/home/pi/vision/grip:$LD_LIBRARY_PATH java -jar /home/pi/vision/grip/grip.jar /home/pi/vision/grip/project.grip
Replace any paths with the proper ones for your set up, and make sure you have the libntcore.so and libstdc++.so.6 in there. This worked for me, but I'm switching to straight OpenCV for other reasons. Hope that helps.

Re: GRIP Deploy Not Working
I tried that but now it can't create a JVM. I'm just going to run GRIP on the driver station and stream the camera through the RIO USB port. Maybe we can get openCV running on the Pi next season. Is there a guide you followed for getting it to work with Network Tables?

Having a similar problem. Are you saying the GRIP deploy window will never succeed on the pi (at least until GRIP is patched)? After the deploy operation, is GRIP ready to run on the pi?

Re: GRIP Deploy Not Working
You need to set the "LD_LIBRARY_PATH" environment variable to have the directory you put the ntcore libraries. You can do this either by the method on the wiki:

Code:
$ env LD_LIBRARY_PATH=/home/pi/vision/grip:$LD_LIBRARY_PATH java -jar ...
or by setting it in the .bashrc file in your home directory by adding this line:

Code:
export LD_LIBRARY_PATH=/home/pi/vision/grip:$LD_LIBRARY_PATH
You can edit this file with "$ nano ~/.bashrc".

Speaking on behalf of the amateur programmers, seeing this answer and others like it, I think I've found the problem.
I think we missed this line in the wiki guide:
"From the deploy window, click deploy. Once it's finished deploying just hit stop as GRIP will fail to run properly due to library issues."

We're supposed to get the errors when we deploy, its normal, we should ignore it, and continue down the wiki where we run GRIP from the command line using the "env". I understand this is an RTFM error on mine and others' parts, but it might eliminate some questions if this was highlighted a bit more in the wiki.
Correct?

Well, I did that, and from the command line I'm getting:
Code:
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_S_construct null not valid

Yeah, the wiki could be better.

Can you post the full stacktrace?

Can you post the full stacktrace?
Pardon my ignorance but Linux is not my first language, where can I find the full stacktrace?

Re: GRIP Deploy Not Working
It's the entire output you got when you tried to run it from the command line, not just that one line. There should be a lot of lines that look like

"at edu.wpi.grip....(123)"

Re: GRIP Deploy Not Working
That's not a Java stack trace (it appears to be something in libstdc++), so I doubt there's anything else. I would recommend double-checking and making sure the correct libstdc++ is in the same folder you have in LD_LIBRARY_PATH, but I'm not really familiar enough with GRIP, so I can't offer much more than that.

I will get the full output when I get home.
I definitely have the files linked to on the wiki there. Only difference is that I ftp'd them there and not scp. The only reason I can think that might make a difference is if the file permissions don't set the same.

I'm using a RPi3, putty ssh via a peer to peer. I do not have a RoboRio on the network right now.
I did alter the start_vision.sh from the wiki to include a -b to run in the background. Without it, I found the mjpg_streamer sat there and grip never started.
Any help would be appreciated.

Combined Vision Starting Script
Start mjpg streamer
enabling daemon modeforked to background (776)
/home/pi/vision/start_vision.sh: line 5: pause: command not found

Edit: Seeing the pause error, I changed that line to read-p "--" and just counted to 5 before continuing. Same result.
Edit2: pulsatrix is the name of the pi. Its the species name of the spectacled owl

Re: GRIP Deploy Not Working
That's bizarre. I'll see if I can reproduce this tonight. If not, you can use 1.5 and generate OpenCV code to run on the Pi without needing to deploy GRIP

Just to be clear, this is the ssh window, not the grip deploy log.

If its helpful, these were my Deploy window errors (which its my understanding that Pi users should ignore):
Code:

    ... 2 more
I don't know how to view the 2 more.

I have also attached the GRIP log. I'm 90% sure this is the newly generated file from last night running from command line, but I just realized the date is wonky on my pi so I am not 100% sure. (file format changed to txt for cd post)
Attached Files
File Type: txt GRIP.txt (29.9 KB, 1 views)
