Openjk on Raspberry Pi

[aramil248]

I was wondering how i could get ja/openjk running on my raspberry pi?

[ensiform]

Compile it from source and see if it works?  I think there is basic arm support but I don't know if there will be issues or not.  You may only be able to get a server running.

How would I compile it? I'm not compiling it on the pi that would take forever

[Futuza]

@@jakub742 just did this a while ago, he could probably help you out and I know @@capturesteve has as well.

 

You'll want to cross compile it (the official raspberry pi website recommends following this tutorial to install a vm ubuntu and compile there), Raspberian is a Debian based linux so it should be basically the same as compiling on a debian based distribution of linux.

You won't be able to run it as far as I know, even if you can get it to compile. The rpi only supports OpenGL ES and not OpenGL.

I've compiled the whole MP codebase on an RPi before, but only successfully ran the dedicated server with jampgame and confirmed it working online.

[aramil248]

what i was going to try to do was compile it on my desktop then ftp it to the pi then try to run it on the pi

According to the raspberry pi foundation the Raspberry Pi 2 supports OpenGL as of the latest Raspbian release https://www.raspberrypi.org/blog/another-new-raspbian-release/

[Xycaleth]

Ah ok. Good to see it's finally supported! in that case as long as the client code can be compiled, then it should just run. Provided OP has an rpi2.

[ensiform]

That page says its experimental an disabled by default.

[Ziggurat]

That page says its experimental an disabled by default.

Yes, and how to enable it, and some known problems.

[aramil248]

So how will I compile openjk for arm on ubuntu 64bit?

[Raz0r]

I don't have exact steps for cross-compiling, but the gist of it is: You need a CMake toolchain file for Raspberry Pi. There should be some good examples around the interwebs.

i dont get what you said but ok I will Google about it

I think this might be a good place to start, I have not inspected the steps

[Boothand]

Ouned did this with JK2. As for me, I haven't even figured out what a raspberry pi is yet, other than a.. chip

So you were able to get around the issue that @@capturesteve ran into with the server not being visible on the network?

OP, if you change your mind on cross compiling, the instructions to build OpenJK on the pi are in the link above.

[aramil248]

ok so far i got it all to compile by just using the steps for compiling it on pc right now im ftping the pk3s from the disk to the pi will post what happens

Do you have OpenGL drivers installed?

[aramil248]

I did install them but did not reboot after maybe I should of

[Futuza]

You can test if OpenGL is installed with this:

glxgears

Install with this:

sudo apt-get install mesa-utils

[aramil248]

so i got it to load to the main menu but then when loading up a solo game the pi froze up on loading ffa1

[Xycaleth]

What did you change to get further? Do you get any errors in the terminal or console when it froze up?

[SomaZ]

Maybe you can ask this youtuber.
