11 years ago By default, Clang uses the C++98 standard. <thread> requires C++11.
You should be able get this to work by adding -std=c++11 to your ac-clang-cflags. Try using M-x ac-clang-set-cflags to set it to just -std=c++11. You probably don't need to explicitly list those system include paths which are shown in your config; your Clang installation should already know about them.

This is the config I have and it works fine for a lot of libraries, but the library
as installed on ubuntu 13.04 doesn't work at all. Should one declare the defines
used in thread library like
if defined(_GLIBCXX_HAS_GTHREADS) && defined(_GLIBCXX_USE_C99_STDINT_TR1)
somewhere in a cflags file ?
