【问题描述】：

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:

还有这条消息

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

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

它有效，所有上述错误都消失了，但是.... 我收到了新的以下错误：在此代码上

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

“词法或预处理器问题”下的错误 在 CCDirector.h

当我删除“#include stack”行时，我得到了新的错误：

 'thread' file not found

等等.....

因此，我认为这个解决方案对我来说是无效的或者我可以解决 'stack' file not found ???

感谢您的帮助。

【问题讨论】：

我认为你包含错误的库。
您是否按照这些说明进行操作？ help.buildbox.com/en/articles/…
@HWilmer 不是这个，我会检查一下，也许我错过了什么......谢谢你的帮助

【解决方案1】：

我知道已经很久了，但无论如何，

这个解决方案>>>

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

会引起注意，

一开始的问题是这个项目中有一些库和 SDK 不支持 Xcode 模拟器（我已经询问了 SDK 所有者的支持）

当我构建了我的应用并在真实设备上对其进行测试后，一切正常。

这就是我的情况，如果您在构建项目时遇到这个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
