Rebuilding Debian with LLVM/Clang - Sylvestre Ledru, Debian / IRILL
Channel: Linux Plumbers Conference
Date: 2013-10-15

"After extending Debian with two new kernels, Debian will soon be able to be built with a new free C, C++ and Objective-C compiler called Clang. Debian being one of the biggest distribution in term of number of packages (more than 18000), it represents an excellent test for a new key component like a compiler.
Based on LLVM, this compiler is now close to gcc on many different aspects (performances, build time, level of support of C and C++). 

This talk will present the current status of a clang-build version of Debian, the different issues faced, the next steps and evolutions.The rebuild shows that around 12% of the software packaged in Debian are failing because of programming mistakes. Fixing all of them would require a huge effort.

Therefor, how can we make clang more know to make upstream fix their issues ?
How can we make distributions collaborate on this aspect ?" http://www.linuxplumbersconf.org/2013/
