Getting . # error "No thread API"

[Neeraj garg]

Hi, 

   I recently moved my codebase to C++14 and libc++_shared as stl library . While compiling my code, i am getting following error:

        ndk-bundle/sources/cxx-stl/llvm-libc++/include/__config:825:4: error: "No thread API"

  I checked the file __config . I found the following check 

     // Thread API

           #ifndef _LIBCPP_HAS_NO_THREADS

          # if defined(__FreeBSD__) || \

         defined(__NetBSD__) || \

         defined(__linux__) || \

         defined(__APPLE__) || \

         defined(__CloudABI__) || \

       defined(__sun__)

       #  define _LIBCPP_THREAD_API_PTHREAD

       # else

       #  error "No thread API"

       # endif // _LIBCPP_THREAD_API

       #endif // _

  I tried the same thing with native android application . But i am not getting the error. Is there any flag that is undefining the platform from my codebase?

Thanks
