git for source codes

git clone https://github.com/raspberrypi/quake3.git

cd ./quake3
vi build.sh

make it look like this:

Save this file and go ./build.sh          :D

Start compiling, it might take hours. Just be patient :D

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

     http://dl.dropbox.com/u/1816557/Q3%20Demo%20Paks.zip

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.
