Winsock 服务器的错误 C1083 Visual Studio 2013

Question

我是这个网站的新手。

我搜索了很多解决方案，但一无所获。

我在另一个项目上编写了服务器和客户端，它正在工作，但我想重新编写它以获得更好的结果。

但我不知道为什么我有一些错误：错误 C1083：无法打开：'Debug\chatserver.pch'：没有这样的文件或目录 c:\users\x\documents\visual studio 2013\projects\chatserver\chatserver \chatserver.cpp

在此错误之前，我在“itoa”功能上遇到了另一个错误：C4996 'itoa' POSIX ... （itoa 函数正在我的第一个服务器项目上工作）

我在 LNK 2011 到 .obj 时也有错误

这是代码：
