There are several things that need to be true for your code to work:
You need to
#include <atomic>
You need to compile the code as C++11 or C++14 (
-std=c++11
or-std=c++14
(orc++0x
for older compilers))Your compiler and standard library needs to support enough of C++11 to provide
atomic
(http://clang.llvm.org/cxx_status.html)
Solution 2
Adding -std=c++11
to CXXFLAGS in my Makefile -> that works for me!

Why doesn't
std::atomic<int> index;
Work?
Currently using LLVM 3.1 with these params
