→How do I access the sample source code for the Raspberry Pi and build the multimedia demo programs?
# Ensure that the <code>raspberrypi-vc-demo-source</code> package is installed (it's installed in the released image).
# Install the C/C++ toolchain. If you have sufficient space (about 600M), it's recommended that you install the full set of development tools and libraries (<code>yum groupinstall "Development Tools" "Development Libraries"</code>). Alternately, you could install a minimal set of tools (gcc, make, etc). (TODO: come up with the minimum set of tools/libraries needed for the demo code).
# It's recommended that you build and run the code as a regular user:
## Make a personal copy of the source code in your home directory: <code>cp -R /usr/share/raspberypi-vc-demo-source/hello-pi ~</code>
## As root, change the permissions on the vchiq device so that all users can access it: <code>chmod a+rw /dev/vchiq</code>
