Running xmage in Raspberry Pi

[pyested]

Hi, I've tried to install xmage on a Raspberry Pi 400 (arm64 processor), but it seems that the dedicated java environment that is automatically downloaded during installation (i.e. jre 8u201) is specific for amd64 architecture. I'm able to run the .jar file from the terminal after installation, but when I try to launch the client I get an error message since the dedicated java environment cannot run on the Pi 400.

Is there a way to work this around or are there any plans to add support to arm64 architecture? Thanks a lot!

mage-server and mage-client folders contains sh and other scripts to run under default os java version. You can try to use it instead launcher.

Another option: find and download your java version and extract to launcher/java folder (keep same files structure as old version from a launcher downloader).

I've tried both and I found this:

1. Using my default os java version (openjdk-17) and the sh script I could launch the client but I couldn't connect to the server. All the rest was fine (images, etc). Not sure why this happened, I tried the same in my laptop (openjdk-11) and I could connect to the server.

2. I also downloaded jdk 8u391 for arm64 (link to Oracle page) and I simply extracted the content in the java folder but I kept the old folder name inside (jre1.8.0_201) so the launcher wouldn't mess up. I couldn't find jre for arm64, so I've dowloaded jdk and it has worked fine. In this way I could both launch the client and connect to the server, so it's definitely possible to run xmage on Raspberry Pi.

3. There is simply one little detail. Once inside the client some of the buttons look odd. I attach an image so you can see this. Is there a reason for this to happen?

Try to apply d3d fix param from here (if you run from sh script then add that param to it instead launcher settings): #4626 (comment)

There are many other 2d and 3d params for opengl too (I think it can be useful for your use case):

Thanks a lot for all the support! It works now. My Pi 400 is using x11, but after enabling opengl and configuring the java pipeline using the commands above to launch the client the buttons look as they should:
