Building Quake 3 in Raspbian

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

  1. Make sure you're up-to-date: 
        sudo apt-get update
    sudo apt-get dist-upgrade
    sudo rpi-update 192
    • Reboot.
  2. Install required packages: 
        sudo apt-get install git gcc build-essential libsdl1.2-dev
  3. Download the Quake 3 source code: 
        mkdir ~/src
    cd ~/src
    git clone https://github.com/raspberrypi/quake3.git
    cd quake3

  4. Edit build.sh in quake3 directory: 

        change line 8 to this:  ARM_LIBS=/opt/vc/lib
    change line 16 to this: INCLUDES="-I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads"
    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. Update your permissions for directFB access: 
        sudo 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. 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

  • Compiling fails, complaining about missing vcos_platform_types.h file. See this issue in RasPi repository: https://github.com/raspberrypi/firmware/issues/34. (Build script was recently fixed to include correct path to missing header file. Do git pull.)

  • Game cannot find Broadcom libraries. As root do: 
        cd /etc/ld.so.conf.d/
    echo /opt/vc/lib >broadcomlib.conf
    ldconfig

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

        echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/10-vchiq-permissions.rules
    usermod -a -G video [your_username]
    • Or as one time temporary solution (until reboot): 
        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.
