Making SBOMs for modern languages is easy - point a tool at the lock file, crank the handle, almost done (apart from all that pesky NTIA stuff). But C presents challenges as there's no widely used package manager to serve up log files, and many tools over promise and under delivery. This talk will run through various attempts to create SBOMs for a C project, and why the tools proved inadequate. It will also take a brief look at projects like Yocto where getting SBOMs for C stuff is working.
