Ioquake compiled on Raspberry Pi 2 runs with black screen from the console

ioquake3

I’m unable to get ioquake3 to run with video. The program runs with a black screen, but the sounds run fine. I have to quit by blindly entering the console and typing /quit.

I have compiled SDL2 with the following PKGBUILD for Arch Linux. This file has been altered from the original:

I am attempting to use the build_rpi_rasbian script that I found and slightly modified. The original is here: https://github.com/raspberrypi/quake3/blob/master/build_rpi_raspbian.sh

#!/bin/bash

exit 0

I had to prepend “SDL2/” to the source code files that complained about missing libraries during the compile. These are in ioq3/code/sys/sys_loadlib.h and ioq3/code/sdl/sdl_input.h. Other than that, the source is the same.

Here is the output of ioquake3:

ioquake3 will compile fine and run fine without the build_rpi_rasbian script, but it is very slow.

Is there some other way I can get this to run with the OpenGLES libraries included with the Raspberry Pi 2?

Thank you for any help!

We don’t have an official GLES branch or renderer yet, so unfortunately you’re left to the various ioquake3 forks for that. The last good one I was familiar with was kwaak3 for android but that has not been updated in years. https://code.google.com/p/kwaak3/

The glGetError 0x502 means OpenGL is out of memory. Try increasing the Raspberry Pi’s GPU memory in the main / GPU memory split. Probably need to add gles render code though.

4

I went ahead and increased the split to 384 MB but I got the same error. I get 0x0500, 0x0501 and 0x0502, and some of those are illegal instructions if I’m reading the descriptions right.

The executable runs fine if you are blind. :slight_smile:

I have the free time, but I don’t have the ability to fix this and contribute. I am not familiar with OpenGL, and that seems to be the first step to take. Then, I’d have to learn OpenGL ES, which seems to be markedly different. I looked at a free class at MIT Courseware on graphics, but it only loosely introduces OpenGL. Most of the work I’ve done in programming concerns databases.

Try using this fork of ioq3:

You also need the libudev development package

You will need to compile SDL2 yourself with these configure options:

./configure --host=armv7l-raspberry-linux-gnueabihf --disable-video-x11 --disable-video-opengl

Good luck.
