I am having issues with setting up Eclipse CDT to correctly do development in C++11. It's highlighting std::error_code and honestly everything in the std namespace.
The full project can be found on github.com/rbaindourov/OpenWeatherMapDSLink including the hidden files used by Eclipse.
I can host the the OVA of the virtual machine if you like as well.
Thanks in advance to any industrious individual who is willing to take the time to help me configure Eclipse CDT correctly.
And apologies if my question is not to your liking.
