“未定义的建筑符号 x86_64” Xcode

Question

这是我第一次使用 Xcode V11.3.1

我正在尝试在 Xcode 上编译 Buildbox 3 项目，但我得到了错误列表， 36 错误均以以下内容开头：

Undefined symbol:

和这条消息

以及其中一些错误消息：

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*)

经过长时间的搜索，我找到了使用以下方法的解决方案

*

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

*

它有效并且所有上述错误都消失了但是...... 我收到新的以下错误：在此代码

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

错误 "Lexical or Preprocessor issue" 关于 CCDirector.h

当我删除“#include stack”行时，出现新错误：

 'thread' file not found

等等.......

因此，我认为这个解决方案对我无效或者我可以解决 'stack' file not found ???

感谢您的帮助。

Answer 1

我知道已经很久了，但无论如何，

这个解决方案>>>

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

会引起注意，

问题从一开始就是这个项目中的一些库和 SDK 不支持 Xcode 模拟器（我已经询问了 SDK 所有者的支持）

当我构建我的应用程序并在真实设备上对其进行测试时，一切正常。

这是我的情况，如果您在构建项目时遇到此问题，而不是在模拟器上运行时遇到此问题，请尝试上述解决方案或检查此 post
