Undefined symbol:

and this message

and some of these error messages:

After a long search I found a solution using the following

project >> Build setting >> Apple clang - Language - C++ >> Change C++ Standard Library to libstdc++ (GNY C++ Standard Library )

it works and all above errors is gone BUT.... I got new following error: on this code

#include <stack>            'stack' file not found
#include <thread>
#include <chrono>

error under "Lexical or Preprocessor issue" on CCDirector.h

and when i remove " #include stack " line, i got new error:

 'thread' file not found

And so on.....

Therefore, I think this solution is ineffective for me or can i solve 'stack' file not found ???

Thanks for any help.

Solution

I know it's been a long time but anyway,

this solution >>>

project >> Build setting >> Apple clang - Language - C++ >> Change C++ Standard Library to libstdc++ (GNY C++ Standard Library )

will lead to noting,

the issue from the beginning is there are some libraries and SDKs inside this project doesn't support Xcode simulators (i have asked the SDK owner support about that)

and when I have built my app and test it on a real device, everything works fine.

that was my situation, if you faced this issue when building your project not when run it on simulators, try the above solution or check this post
