Unable to initialize SDL backend even though SDL is installed.

[RainMa22]

Hello, I really do appreciate the work you have put into this project. However, some issues occurred when I tried to run this program. The Exception is as follow: Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class arc.backend.sdl.jni.SDL at mindustry.desktop.DesktopLauncher.message(DesktopLauncher.java:315) at mindustry.desktop.DesktopLauncher.lambda$handleCrash$8(DesktopLauncher.java:176) at mindustry.desktop.DesktopLauncher.handleCrash(DesktopLauncher.java:176) at mindustry.desktop.DesktopLauncher.main(DesktopLauncher.java:44)

I have already installed libsdl2-2.0-0, the SDL2 package available on the Raspi Bullseye repo.

My Device is Raspberry Pi 3 B(1GB) My OS is Raspberry Pi OS Bullseye 64bit

Thanks in advance.

Will look at it. Is that all that was printed? Can you try to run it with java -verbose:jni?

[RainMa22]

Yes, that's all the messages, typing

java -jar MindustryPi.jar -verbose:jni

Gives the same result as well.

I tried downgrading the jre from openjdk17-jre to openjdk11-jre, the problem still persisted.

I have a problem with sdl

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class arc.backend.sdl.jni.SDL at mindustry.desktop.DesktopLauncher.message(DesktopLauncher.java:312) at mindustry.desktop.DesktopLauncher.lambda$handleCrash$8(DesktopLauncher.java:175) at mindustry.desktop.DesktopLauncher.handleCrash(DesktopLauncher.java:175) at mindustry.desktop.DesktopLauncher.main(DesktopLauncher.java:45)

Can you please solve the problem?

Hello, I have the same problem

Tried Version 126 can't install "sudo apt install libsdl2-2.0" but install "sudo apt install libsdl2-2.0-0" instead I have a Raspberry Pi 400 with bullseye installed.

Same happens with the new bookworm based Raspberry OS.
