C++ “；架构x86_64”的未定义符号；Xcode

这是我第一次使用Xcode V11.3.1

我试图在Xcode上编译Buildbox3项目，我得到了错误列表， 36所有错误都从以下内容开始：

Undefined symbol:

这条消息呢

经过长时间的搜索，我找到了一个使用以下方法的解决方案

*

项目>构建设置>苹果铿锵语言-C++ >更改C++ 标准库到LIbSTDC++ +（GNY C++标准库）< /P> *

它起作用了，上面所有的错误都消失了，但是。。。。 我得到了以下新错误：在这个代码上

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

等等

因此，我认为这个解决方案对我来说是无效的 或者我可以解决找不到“堆栈”文件的问题吗

谢谢你的帮助。

我知道已经很久了，但不管怎样

此解决方案>>>

项目>构建设置>苹果铿锵语言-C++ >更改C++ 标准库到LIbSTDC++ +（GNY C++标准库）< /P> 将导致注意，

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所有者支持部门）

当我构建了我的应用程序并在真正的设备上进行测试时，一切都很好

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项目时，请尝试上述解决方案或查看本文

我认为您将库包括在内是错误的。您是否遵循了这些说明@不是这个，我会查出来的，也许我错过了什么。。。谢谢你的帮助

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

 'thread' file not found
