Okay, so I just tried to build on linux.

I did get my permissions fixed (at least for /dev/ttyUSB0 ) so now I am not running it sudo, and It is using the files in ~brynn/.openpnp

I did this:

cd /home/brynn/PnP/openpnp-develop

mvn package

and I got lots of stuff, ending with this:

Have you ever compiled it already or it's your first time? Always normally before but troubles only now?

Do you have Java 8 or 9? I see there are some errors related to opencv and there is some "conflict" between java9 and opencv...

This is the first time I have tried on linux.

Not sure what Java it has.

It's not clear for me why there are some errors from reading machine.xml. Do you have machine.xml in openpnp-develop? Maybe try delete machine anywhere it is located and maven again.
Check java version necesary (java -version from console should tell you), I didn't track it but saw Jason many times warned about problems with java9.

Ah, I did nothing special with machine.xml. Hopefully the openpnp-develop comes with a copy in the right place (which I assumed it would).

My working copy is in ~brynn/.openpnp/machine.xml (I checked and I no longer need to run it sudo root , as when I switched to /dev/ttyUSB0 it worked right without sudo)

Sorry for maybe stupid question, but do you try to maven downloaded working openpnp or the source taken from github?

I downloaded openpnp-develop from github, I did sudo apt install maven. Then tried mvn package

There is an issue in develop with opencv. Either use the master branch or see if installing ffmpeg lib helps. The machine.xml error is due to opencv not loading properly.

This issue with opencv occurs in case of both Java 8 and 9?

Jason von Nieda

There are two issues:

1. The library loader used by the opencv package is not compatible with Java 10. This affects every version of OpenPnP but only on Java 10.

2. The new build of the opencv package was built incorrectly and linked against ffmpeg. This means that when it loads it tries to find libffmpeg and if that isnt installed it fails to load. This affects only the develop branch and all versions of Java.

I’ll be fixing both issues next week. Until then my recommendation is to use Java 8, with the master branch, if you are doing development work.

What is the difference between the 'master' branch and the openpnp-develop branch? when and why should we use one over the other?

See the descriptions at http://openpnp.org/downloads/. Develop and master are names of the branches in Git. Develop is “Latest”, master is “Stable”.

Develop is merged to master approximately monthly. The new opencv package causing problems is currently in develop and has not yet been merged to master.

It sounds like you are using Java 9. Please post output of java -version and javac -version.

yes you are correct:

openjdk version "10.0.2" 2018-07-17

How do I switch it debian?

It looks like you have a mix of packages installed. Use your package manager to remove all Java packages (openjdk, openjre) and then install ONLY openjdk 8.
