#endif /* !defined(_M_IA64) && !defined(_M_AMD64)*/当我编译它时，我要求在我的代码中插入#includestdafx.h。当我这样做时，它向我显示了很多链接错误我知道stdafx.h需要成为第一线。经过一些谷歌搜索，我想包括#if！定义（_M_IA64）&& ！在我的stdafx.h文件中定义（_M_AMD64）。但它也没有用。有什么建议吗？
stdafx.h -
When i compile it asks me to insert the #include"stdafx.h" in my code.When i do that it shows me a lot of linking errors.I know that "stdafx.h" need to be the 1st line. After some googling i thought to include the #if !defined(_M_IA64) && !defined(_M_AMD64) in my stdafx.h file. But then also it didnot work. Any suggestions?
"stdafx.h"-
// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
//
//#if !defined(_M_IA64) && !defined(_M_AMD64)
#pragma warning( disable: 4049 )
#pragma once
#include "targetver.h"
#include <stdio.h>
#include <tchar.h>
// TODO: reference additional headers your program requires here
请告诉我为什么当我将stdafx.h置于所有行之上并且如果可能的话建议解决方案时程序是否工作。
Please tell me Why did not the program work when i placed the stdafx.h above all lines and suggest a solution if possible.
推荐答案
我很确定不是编译器要求你插入stdafx.h include而是预编译头管理。
默认情况下，在VisualStudio中，任何新的C / C ++文件使用以下设置添加到项目中：使用预编译的标题。
更改每个C / C +的设置+文件，不需要stdafx.h文件不要使用预编译的头。
如果你想保留stdafx.h文件，你必须请确保：
- 任何#if / #ifdef / #ifndef有#endif
插入#includestdafx.h 位于C / C ++文件的顶部。
I'm quite sure it is not the compiler which ask you to insert the stdafx.h include but the precompiled header management.
By default, in VisualStudio, any new C/C++ file is added to the project with the settings: Use precompiled header.
Change the settings on each C/C++ file which do not need the stdafx.h file with "Do not use precompiled header".
If you want to keep the stdafx.h file, you have to be sure that :
- any #if/#ifdef/#ifndef has its #endif
insert the #include "stdafx.h" at the top of your C/C++ files.
