RockPro64 doesn't execute Processing

Processing for Pi
1

Hi everybody,

I wrote a processing sketch for a photographic installation. I wrote and tested it on my Macbook, and it works like a charm.

Now to include it in the installation I bought a ROCKPro64 4GB single board computer. But I can’t get Processing to work on it.

As an OS I installed “Armbian Ubuntu 18.04 Bionic Desktop” and “Ubuntu 18.04 Bionic LXDE Desktop aarch64”. (see http://wiki.pine64.org/index.php/ROCKPro64_Software_Release).
I tried both the Linux 64-bit and Linux ARM release of Processing in both OS’s. But on execution nothing seems to happen.

Does anyone have a clue on why it’s not working? Or even a hint to solve my problem?

Thanks in advance!

-a- what / how you install processing,
-b- did you test

java -version

like on Raspberry Pi

have 3 way,

  • a image
  • a curl command ( i used )
  • a tar file

and on

pi@RPI3BP:~ $ java -version

java version “1.8.0_65”
Java™ SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot™ Client VM (build 25.65-b01, mixed mode)

i understand you think you might be lucky if someone here use the same board,
but did you try to ask other board users like at

Sorry for my late response, but had to figure out some stuff before I could answer the questions. I’m new to Linux and struggling getting things to work. ANd thanks kll for your response.

  1. I tried the Raspberry image, but it didn’t even boot

  2. I now use “Ubuntu 18.04 Bionic LXDE Desktop" as the OS. I installed “Processing 3 Linux ARM” bij downloading the package and unpacking it to /opt (using sudo xarchiver). I opened LXTerminal and tried to run Processing by making /opt/processing-3.5.3 the current folder (cd /opt/processing-3.5.3) and typing ./processing. Response: java: not found.

Than installed Java by first typing
sudo add-apt-repository ppa:webupd8team/java
sudo apt update
sudo apt install oracle-java8-set-default

Than again tried to run Processing by making /opt/processing-3.5.3 the current folder (cd /opt/processing-3.5.3) and typing ./processing. This results in a java.awt.headless exception

And that’s where I am now…

I have only slight understanding of what I’m doing. But turns out that ‘headless’ means without monitor, keyboard or mouse. But I have no idea of how to get java into headful mode.

Am I on the right track?

Anybody any suggestions?

Actually i would be interested in this also, have been running processing for android on the rock64 with the android tv mode and its been brilliant. If anyone has made progress on a linux distro let me know, else will dip my toes in soon.
