and some of these error messages:

Undefined symbol: PTAdInvoker::rewardedVideoDidReward(char const*, bool)

Undefined symbol: PTAdInvoker::interstitialFailed(char const*)

Undefined symbol: PTAdInvoker::interstitialLoaded(char const*)

Undefined symbol: PTAdInvoker::rewardedVideoFailed(char const*)

Undefined symbol: PTAdInvoker::bannerFailed(char const*)

Undefined symbol: PTAdInvoker::bannerFailed(char const*)

Undefined symbol: PTAdInvoker::rewardedVideoLoaded(char const*)

Undefined symbol: PTAdInvoker::networkFailed(char const*)

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.

  • I think you are including the library wrong. – HWilmer Feb 21 '20 at 22:18
  • Did you follow these instructions? http://help.buildbox.com/en/articles/3436281-xcode-ios-installation-instructions-for-ironsource-with-mediation-for-admob-applovin-and-unity-ads-game-analytics-and-tenjin-part-1 – HWilmer Feb 21 '20 at 22:22
  • @HWilmer not this one, i will check it out, maybe i missed something... thank you for help – Mohamed Awad Feb 22 '20 at 11:03

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

Xcode build failure "Undefined symbols for architecture x86_64"
