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.
解決方案：
1、去掉預編譯頭
項目->屬性->配置屬性->c/c++->預編譯頭->創建使用預編譯頭->不使用預編譯頭
2、將包含文件加到預編譯頭stdafx.h文件中
3、在每個.cpp中包含預編譯頭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，否則還是會出現類似錯誤！
