I am using Eclipse IDE for C/C++ Developers Version: Luna Service Release 1 (4.4.1).
My auto completion works in general and I can compile correct c++11 files. However features for specific C++11 features don't appear in the auto completion (e.g. emplace_back function for certain containers or new containers such as forward_list).
They compile fine though so that is not the problem.
So far I tried changing the language dialect to c++11 from the project settings. This allows the program to compile fine but no auto completion.
NOTE: The code compiles fine. It's the auto completion that's not working.
