#include skipped when looking for precompiled header use -- unexpected end of file while looking for precompiled header
提问by Иван Бишевац
I have some code but it wan't compile. I can't go further with this example because this error raises every time I try to debug. Note: I am Java programmer, and this message in VS is strange and I coudn't find what is problem. Can someone explain me what this error mean?
我有一些代码，但它无法编译。我不能在这个例子中更进一步，因为每次我尝试调试时都会出现这个错误。注意：我是 Java 程序员，VS 中的这条消息很奇怪，我找不到问题所在。有人能解释一下这个错误是什么意思吗？

You want
你要
#include "stdafx.h"
in your String.cpp file, as with all .cpp files.
在您的 String.cpp 文件中，与所有 .cpp 文件一样。
回答by Jesse Good
You using the default MSVC project which includes precompiled headers. I would recommend selecting "Dont use precompiled headers option" when you make a project.
您使用包含预编译头文件的默认 MSVC 项目。我建议您在创建项目时选择“不要使用预编译头选项”。
回答by Nenad Bulatovic
You should add
你应该添加
#include "stdafx.h"
in your String.cpp file, but if you used precompiled headers you have to put it on the TOP, such as this:
在你的 String.cpp 文件中，但如果你使用了预编译的头文件，你必须把它放在 TOP 上，例如：
#include "stdafx.h"
#include "String.h"
#include <iostream>
using namespace std;
#include <string.h>
There is extensive discussion herewhy precompiled headers must come first.
这里有广泛的讨论 ，为什么必须首先使用预编译头文件。
Everything before the PCH is ignored by the compiler, therefore PCH must come first.
PCH 之前的所有内容都会被编译器忽略，因此 PCH 必须排在第一位。
