java problem on armbian

[bloodyjo]

I'm trying to install minimserver on armbian system.
java version is :
openjdk version "11.0.12" 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+7-post-Debian-2deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.12+7-post-Debian-2deb10u1, mixed mode)

at start with "minimserver/bin/startc" i have this error message :

java.lang.UnsatisfiedLinkError: /home/eventia/minimserver/tmp/native/libohNet.so : /home/eventia/minimserver/tmp/native/libohNet.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

MinimServer error: now stopped, use 'restart' or 'exit'

if i type restart , minimserver starts normaly and is usable. I can acces trought web remote . autostart don't work and minimserver/bin/startd either.

google search point me to install java 32bit i tried but it still doesn't work.

What is the hardware architecture for your device and operating system: armv5/armv6/armv7/armv8, soft float/hard float, 32/64 bit?

Harware is a TV box based on amlogic s905x chip so ARMv8 (a53 cores) , should be hard float , 64bit
operating system is armbian

Is the operating system also 64-bit? For example, Raspbian for the RPi4 is 32-bit even though the hardware is 64-bit.

If the OS is 64-bit, you should be using 64-bit Java. From the error information you posted, it looks like this is what you are using.

When you start MinimServer, the log should contain a message "System platform is ...." What does this say?

just looked into log
System platform is linux-armhf

This is 32-bit ARMv7. You need 32-bit Java and the MinimServer download for ARM hard float.

no system is arm64

(Post edited to remove incorrect information)

I checked what is shown as "System platform." This corresponds to the version of MinimServer that is installed, not the version of Java. If your system is arm64 and you are using 64-bit Java, you need the ARM 64-bit version of MinimServer.
