【中文标题】查找预编译头文件时意外结束。您是不是忘记将#include stdafx.h 添加到您的源代码中?【英文标题】:unexpected end of file while looking for precompiled header. did you forget to add #include stdafx.h to your source?查找预编译头文件时意外结束。您是否忘记将#include stdafx.h 添加到您的源代码中? 【发布时间】:2017-06-30 06:24:03 【问题描述】:所以这是我的代码,我不断收到“在查找预编译头文件时出现意外的文件结尾。您是否忘记将#include stdafx.h 添加到您的源代码中?”所以我将它添加到所有标题和文件中,它仍然说同样的错误。如何摆脱错误?
附:如果你不介意检查这段代码是否回答了这些问题(乘法和除法重载我才刚开始,但关系和相等应该没问题)

【问题讨论】:
What's the use for "stdafx.h" in Visual Studio?的可能重复 不要将#include "stdafx.h";
放在标题中。将其放入 CPP 文件中。并确保它是第一个包含。忽略 stdafx 之上的所有内容。
【参考方案1】:
#include "stdafx.h"
必须是配置为使用预编译头文件的每个源文件中的第一个包含(顺便删除无关的;
字符)。这些文件必须具有-Yu
编译标志。
还必须有一个创建预编译头文件的源文件。传统上这称为stdafx.cpp
,并且只包含单行#include "stdafx.h"
。此文件必须具有 -Yc
编译标志。
【讨论】:
【参考方案2】:在 Visual Studio 中,您可以创建 C++ 项目 -> EmptyProject,而不仅仅是添加带有 int main()
函数的 main.cpp 文件。在这种情况下,一切都可以正常工作,并且不需要预编译的头文件。
