I did a git pull which updated me to f53d70f759a0b87048576bc87729b368a2d767a9, deleted the build directory (and the libcxx-abi symlink I created), and reran cmake and ninja and I'm not getting any errors involving missing libcxx-abi. I wish I'd saved the error log. I'm really confused by this since I can't find any reference to a libcxx-abi. I'm completely willing to believe user error here (although I cannot for the life of me figure out what I could have done).

That said, libcxx still does not build. I get the same undefined references to various __cxa_ functions (e.g., __cxa_allocate_exception, __cxa_throw, __cxa_free_exception) and some vtables (e.g., __cxxabiv1::__si_class_type_info).

I'm running Ubuntu 16.04.1 LTS on x86-64. I haven't tried on OS X.
