Raspberry Pi supported?

[dhajoglou]

I tried to run the 3.7 jars (4.0 jars seem to be missing from the release section) and got an error about linux-armhf:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Platform "linux-armhf" not supported by class com.raylib.Raylib

So, I thought i'd try to build on Raspberry Pi. I'm getting this error when starting the process. What am I missing?

root@wm-media:~/code/git/jlib# ./build-java.sh

Fix this before trying again

Reason there are no jars on GitHub are they are in Maven repo now. But in any case you will have to compile your own.

Which Pi are you using? I have a 3 I could test on but not a 4.

I think the problem is probably that JavaCPP doesn't have a configuration entry for ARM platform so will need to add one.,,

[electronstudio]

Yeah will need an entry made in src/com/raylib/RaylibConfig.java I think.

i've done a build for my rapsberry pi 3, and uploaded all the jars to the releases section, including the new jaylib-natives-linux-armhf-4.0.0.jar

There is also a new build script, build-linux-armhf.sh

Does this work on your raspberry pi?

[dhajoglou]

I am using a PI3 with the Raspberry Pi Os: Buster.

I'll give this a shot tomorrow both with your jar and attempting to build it myself as well. Thanks for the fast feedback!

My project is for streaming media titles for whitewater kayak racing. I prototyped it with a simple framebuffer library. That worked so moving up to some more featured and java-ed solutions!

[dhajoglou]

I re-pulled the master branch and ran the build-linux-armhf.sh script. It built it and the build process ran the test in com/raylib/Test folder successfully! I then repeated the test with my own quick mod an it worked like a charm!

Thanks for the addition for Raspberry Pi 3!

That's good. Note that on the Pi3 it used to be possible to get better performance by using 'native' opengl video chip drivers that don't use X11. But they changed how this works, so I'm not sure if the X11 drivers are now as good, and I'm not sure if Raylib is still able to compile with the native mode option or not.
