Trouble with Manjaro / Arch Linux

[jtdaling]

Hi,

I am not able to get ShootOFF running on my Manjaro machine. I ran the ShootOFF diagnostic program and got the following message in my log file:

Runtime: Java(TM) SE Runtime Environment 10.0.2+13 64-bit OS: Linux 4.14.70-1-MANJARO amd64, Patch Level: unknown Max amount of memory JVM will use = 1972 MB Intel(R) Core(TM) i5-5257U CPU @ 2.70GHz is64bit = true physical cpu(s): 2 logical cpu(s): 4 CPU Load Per Processor: 14.64% 19.13% 17.94% 17.90% Total RAM Installed: 7883 MB Available RAM: 3867 MB ShootOFF Output:

Graceful shutdown took too much time, forcing the shutdown.

Regards and thanks for your help!

This is a known problem with the OpenCV package we use:

https://github.com/openpnp/opencv/issues/33

Only option at the moment is to use an older version of Java.

Thanks a lot, your solution worked! For those that use Manjaro or Arch, here is how I got Oracle Java 8 installed: First I installed yay (Yet Another AUR Helper) since Oracle's Java is not available under Pacman:

sudo pacman -S git

git clone https://aur.archlinux.org/yay.git

cd yay

makepkg -si

Then I searched for available JDK's with the following command:

yay jdk

And I choose the option:

aur/jdk8 8u181-1 (+58 2.91%) Oracle Java 8 Development Kit

ShootOFF has started, I couldn't check if it runs ok since I don't have a webcam with me to test it.

Hi folks, https://github.com/openpnp/opencv/issues/33 is now fixed so you should be able to upgrade and be back in business.
