Visual C++ Concepts: Building a C/C++ ProgramCompiler Warning (level 1) C4627Error Message
”: skipped when looking for precompiled header use
While searching for the location where a precompiled header is used, the compiler encountered an #include directive for the include file. The compiler ignores the #include directive, but issues warning C4627 if the precompiled header does not already contain the include file.
解决方案：
1、去掉预编译头
项目->属性->配置属性->c/c++->预编译头->创建使用预编译头->不使用预编译头
2、将包含文件加到预编译头stdafx.h文件中
3、在每个.cpp中包含预编译头stdafx.h文件
注意：#include "stdafx.h" 一定要添加到cpp文件的第一行，不能放在如”#include <iostream>“行等的后面，否则还是会出现类似错误！
