While I know, that I can install the latest clang compiler for xenial from http://apt.llvm.org/xenial/ (Doku: https://apt.llvm.org/) I could not determine how to install the latest version of libc++ (llvm's standard library implementation).
Is there a separate repository for that or do I have to manually download and compile the latest version of that library?
Btw.: I know that clang will use libstdc++ by default and most of the time that is OK for me, but sometimes I like to experiment / test my code with libc++ or use features that are not yet part of libstdc++.
