Rebuilding Debian with LLVM - Clang

Explore the challenges and progress of rebuilding the Debian operating system using the LLVM/Clang compiler in this 27-minute conference talk from the Linux Plumbers Conference. Discover how Debian, one of the largest Linux distributions with over 18,000 packages, serves as an excellent testing ground for a new compiler. Learn about the current status of the Clang-built version of Debian, the issues encountered during the rebuild process, and the next steps in its evolution. Gain insights into the performance comparisons between Clang and GCC, and understand why approximately 12% of Debian's packaged software fails to build with Clang due to programming mistakes. Consider the challenges of promoting Clang adoption among upstream developers and fostering collaboration between distributions to address these issues.
