Illegal instruction

[ptitSeb]

looks like a wrapper issue. I'll download the server and see if I can reproduce on my side.

[ptitSeb]

I start the bedrock server just fine on my side. Do I need to do something special to trigger the issue?

Also, what hardware configuration is that: X-Elite or M2 (and if M1/M2: is it with muvm?).

Thanks for your prompt response.

Sorry, yes, some more details:

• this is running on an Apple M1 Max
• the issue is observed within a Docker container running https://github.com/itzg/docker-minecraft-bedrock-server on Docker Desktop 4.39.0

If it helps I could create a minimal image to test; however, my current steps to reproduce are:

Start the image in order to download the server software and prepare the volume:

docker run -it --rm -e EULA=true -v bds:/data itzg/minecraft-bedrock-server

(The execution quietly fails because I have a tool that runs the process to intercept container stop signals. There is currently some issue with it losing the error output from box64.)

Start an interactive shell using the prepared volume:

docker run -it --rm -v bds:/data --entrypoint bash itzg/minecraft-bedrock-server

Within that shell, invoke box64:

box64 ./bedrock_server-1.21.71.01

If it helps, here is the image's installation of box64:

https://github.com/itzg/docker-minecraft-bedrock-server/blob/master/build/setup-arm64

where BOX64_PACKAGE is initialized to box64.

Also let me know if there are some things I can try on my side to help diagnose if you would prefer to avoid the Docker setup.
