c++ - 在 Visual Studio 中使用本地 Windows 调试器运行第一个程序。输出窗口显示无数个 "Cannot find or open the PDB file"

Question

我对 C++ 是全新的，当我运行我的程序时，我在输出窗口中收到一堆输出，看起来像这样(抱歉它有多长)。我的简单程序运行正常，但是当我编写更高级的 C++ 程序时，这会成为问题吗？更重要的是，我该如何解决这个问题？谢谢。这是输出:

还有我简陋的程序:

#include <iostream>
#include <string> 

using namespace std;

int main()
{
string name;

cout<< "Enter your name: ";
cin >> name;
cout << "Hello " << name << endl;

return 0;
}

补充一下@Marco 已经写的，你看到的警告是因为 visual studio 看不到系统 dll 的调试信息(“符号”)。一般来说，这不应该影响您的日常开发，但有时获取额外信息非常有用，例如，如果您必须修复系统代码中发生的崩溃(例如，如果您通过无效的参数或者如果你有一个双删除)。如果你没有这些符号，那么你会在调用堆栈中看到类似这样的内容:

> 0x267823af
  0x27658abc
  0x36726812
  MyBrokenFunction() 

然而，在 Visual Studio 2010 及更高版本中有一个非常有用的选项，您可以在其中打开 Tools -> Options -> Debugging -> Symbols 并勾选使用 Microsoft Symbol Servers 的选项。下次调试时，它将加载大量系统符号(警告:调试器看起来好像挂起，但它正在下载，所以请耐心等待)。然后将这些缓存起来以供下次使用。您现在将获得完整的调用堆栈。
