OH3: Systeminfo not working with armbian

[Tuny (Sebastian)]

openHAB 3.0.0 Build #2071
Platform: Odroid C4 with Armbian Focal mainline kernel 5.9.y
Problem: System Info Binding not working. ERROR: Could not initialize class oshi.jna.platform.linux.Udev

When I create a System Info thing on the local machine I get the following errors in the log.

Unable to load library ‘udev’:

libudev.so: cannot open shared object file: No such file or directory

libudev.so: cannot open shared object file: No such file or directory

This versions of OSGi are installed:
57 │ Active │ 80 │ 4.2.7 │ Apache Karaf :: OSGi Services :: Event
76 │ Active │ 80 │ 4.14.0 │ Apache XBean OSGI Bundle Utilities

Running OH 2.5.10 on the same platform everything is working well.

I tried to install the udef package with the following command:

sudo apt-get install -y udev:armhf

But when I do a restart afterwards the system does not start anymore.
Maybe someone has an idea?
Thanks

[Wolfgang_S]

Looks like there is a mixture of 32-bit and 64-bit binaries.
armhf is 32 bit.
The file /lib/aarch64-linux-gnu/libudev.so.1.6.17 seems to be 64 bit.

What is installed on your system ?
What is the output of

file /bin/ls

What is the output of

cat /proc/cpuinfo

[Tuny (Sebastian)]

Nothing is installed. Just used the script of the following post to install OH3, zulu (zulu11.43.100-ca-jdk11.0.9.1-linux_aarch32hf), frontail and samba:

Guide: How to Install openHAB under Armbian

If anyone wants to install openHAB under Armbian with any of the many devices it supports, you can use the script below if the device has 2gb of ram or more. It will install not only Zulu Java 17 64bit and openHAB 4, but also get your samba shares, mosquito and frontail all setup and working in around 15 minutes. It needs to be run on a clean Armbian image, but it’s working well here on an odroid c2 and now also tested on an Odroid N2+ Don’t run armbian-config, instead do this: wget www.pcm…

Output is:

Thank you for the tip.
The script installs 32 libraries at the beginning. See here:

sudo dpkg --add-architecture armhf
sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install -y libc6:armhf libstdc++6:armhf zlib1g:armhf

This seem to cause the errors.
I now installed zulu11 64 bit with openhabian-config. The version is:

openjdk version “11.0.9” 2020-10-20 LTS
OpenJDK Runtime Environment Zulu11.43+88-CA (build 11.0.9+11-LTS)
OpenJDK 64-Bit Server VM Zulu11.43+88-CA (build 11.0.9+11-LTS, mixed mode)

Now OH3 and systeminfo seem to work fine.
I think 64 bit java was not officially supported unter OH2, some libaries might not work?
I will give it a try with OH3…

Dear Colleagues,

I just installed OH 3 on my Rasp using 32 version and now I can’t get systeminfo working. Please find more details and let me know your feeling/comments how to solve it.
