I'm seeing some build errors for libcxx on Linux (Ubuntu 14.04 LTS):
/usr/local/google/home/blaikie/dev/llvm/src/projects/libcxx/include/__mutex_base:379:5:
error: use of undeclared identifier 'steady_clock'
steady_clock::time_point __c_now = steady_clock::now();
^
Just taking a stab in teh dark that it's related to this commit? Or perhaps
something else time related changed recently?
Anything I can do to fix/debug/help with this?
