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，但出现错误列表， 36错误全部始于以下内容：

Undefined symbol:

和此消息

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

*

项目>>构建设置>> Apple clang-语言-C ++ >>更改C ++ 标准库到libstdc ++（GNY C ++标准库）

*

它可以工作，但以上所有错误均已消失.... 我收到以下新错误：在此代码上

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

“词汇或预处理程序问题” 下的

错误在 CCDirector.h

上

当我删除“ #include stack”行时，出现新错误：

 'thread' file not found

依此类推.....

因此，我认为此解决方案对我无效或者我可以解决找不到“堆栈”文件？

感谢您的帮助。

Answer 1

我知道已经很久了，但是无论如何，

此解决方案>>>

项目>>构建设置>> Apple clang-语言-C ++ >>更改C ++ 标准库到libstdc ++（GNY C ++标准库）

将引起注意，

从一开始的问题是，该项目中有一些库和SDK不支持Xcode模拟器（我已要求SDK所有者对此提供支持）

当我构建了应用程序并在真实设备上对其进行测试后，一切正常。

那是我的情况，如果您在构建项目时遇到此问题而不是在模拟器上运行它时，请尝试上述解决方案或查看这篇文章

Xcode build failure "Undefined symbols for architecture x86_64"
