Atomic Symbols Cannot be Resolved [message #1734371]

I cannot get the IDE to resolve any of the atomic symbols (e.g., atomic<uint>, atomic_uint, atomic_flag) even though it compiles and links fine.

I made sure to add the compilation flag -std=c++11 to both the CDT Cross GCC Built-In Compiler Settings and CDT GCC Built-In Compiler Settings within Eclipse Preferences. These settings are for the entire IDE, not a specific project. This was a suggestion from other forum posts regarding not being able to resolve C++11 library symbols in the IDE. I made sure to rebuild my C++ Index afterwards but no help. This was able to correct not being able to resolve thread symbols but atomic are still not able to be resolved.

I also -std=c++11 as another flag to the GCC C++ Compiler within the Project Properties.

I also made sure I had the latest versions of the CDT tools installed as of today (7-June-2016). I am running Eclipse Mars.2 (4.5.2).

The project compiles fine and works but it is just annoying that the IDE constantly reports errors when there are none.

I can't either. Probably a bug. The indexer has problems with other things too. Some of which have been resolved in later releases.
Possibly because the definition has some conditional preprocessor code that the indexer is unaware of.

Submit a bug report.

To get around it in the meantime, you can try to make definitions just for the indexer and surround them with #ifdef __CDT_PARSER__ ... #endif

Something like

#ifdef __CDT_PARSER__
template<class T>
class atomic {
    atomic(T x=T());
    :
    :
};
#else
#include <atomic>
#endif

Or get used to seeing red underlined code
