The media_build tree appears to be currently broken, at least for my build environment (Fedora 18, gcc 4.7.2, 3.8.4-202.fc18.x86_64 kernel). $ git clone git://linuxtv.org/media_build.git $ cd media_build/ $./build Checking if the needed tools for Fedora release 18 (Spherical Cow) are available Needed package dependencies are met. ... <lots of output> ...
