Building Quake 3 in Raspbian

Documentation below pulled from the Raspbian Forum. Please update this page if errors in the build process are discovered.

I'm about to go to work in a minute, so please enjoy some terribly condensed instructions on how to build a superpowered Quake 3 in Raspbian, using Hexxeh's SD card image as a base. I've probably missed something important, but this should be a helpful start.

  1. Make sure you're up-to-date with everything (aptitude update; aptitude upgrade)

  2. As root: aptitude install gcc build-essential libsdl1.2-dev

  3. Download the Quake 3 source code: 
        git clone https://github.com/raspberrypi/quake3.git
  4. Edit build.sh: 
        change line 8 to this: ARM_LIBS=/opt/vc/lib
    change line 16 to this: INCLUDE_DIR="/opt/vc/include"
    and comment out line 19: #CROSS_COMPILE=bcm2708-

  5. Do a ./build.sh

  6. Wait for compilation to finish, takes about 1 hour on RasPi.

  7. Find copies of the following somewhere (other guides will show you) and place in build/release-linux-arm/baseq3:

    • pak0.pk3, pak1.pk3, pak2.pk3, pak3.pk3, pak4.pk3, pak5.pk3, pak6.pk3, pak7.pk3, pak8.pk3

  8. As root: usermod -a -G video [your_username], log out, log back in. This will allow you to run game as non-root. Works with other directFB/SDL based stuff, too.

  9. If you do not intend to keep Quake 3 source code, you may reorganize files as suggested by this thread on RasPi Forum.

  10. Depending on version of Raspbian you use, you may need to copy Broadcom libraries from /opt/vc/lib to /lib or add them to LDPATH.

  11. As root: rpi-update 192, reboot.

  12. Run ioquake3.arm. Shoot things.

Highly non-scientific testing (i.e. having played a normal-Debian build a few days ago) suggests framerate is quite dramatically improved. Go Raspbian!

Troubleshooting

  • If you get an error like "failed to open vchiq instance" you'll need to: 

    chmod a+rw /dev/vchiq

  • If running as a non-root user and running from the console (non X11), then quake3 may bomb out with an error message like 'SDL_Init()' 'Unable to open mouse'. You'll need to fix permissions so that non-root user can access /dev/input/mice and /dev/input/mouse0.

    • Create new file /etc/udev/rules.d/99-input.rules: 

    # file /etc/udev/rules.d/99-input.rules
KERNEL=="mice", NAME="input/%k", MODE="664", GROUP="input"
KERNEL=="mouse*", NAME="input/%k", MODE="664", GROUP="input"
    • Add a new group and add your user(s) to it: 
    groupadd input
usermod -a -G input [your_username]
    • Log out, log back in.
