Hello Brad! > Are the build logs public? Look for the eMail cron job: media_tree daily build: ????? The ????? is OK, WARNINGS or ERRORS In this eMail there are links to the short and long logfile. Hans uses a complete build system which can download the Kernel sources, build media-build against all of them and does also Sparse and Smatch tests. It even builds gcc 7.x and all of the required tools for you. You can find it here: https://git.linuxtv.org/hverkuil/build-scripts.git BR, Jasmin
