错误 C1010：查找预编译 header 时文件意外结束。您是否忘记在源代码中添加“#include "stdafx.h"”？

Question

我有一个项目，最初是在 Microsoft Visual C++ 上开发的。 NET，版本 7.0.9466，它工作得很好。我尝试使用 MS 2013 来运行我的项目，当我尝试构建项目时，出现此错误信息：

error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?

我已经做过的一些动作：

我在 PropertyPages-> C/C++ -> 预编译 Header 中选择了选项 "Use(/Yu)" on Precompiled Header
我将预编译的Header文件设置为stdafx.h
我把#include "stdafx.h"放在.cpp文件的开头
我必须将 #include "stdafx.h" 更改为 #include "../stdafx.h"，因为我收到以下错误消息：

IntelliSense: cannot open source file "stdafx.h"

这是我收到此消息错误的 .cpp 文件

#include "../stdafx.h"
#include "timedmsgbox.h"

我是 visual studio 的新手，我不知道这一切有什么问题。有人可以帮我吗？

Answer 1

这是智能感知和编译器之间的混淆。

您应该可以通过将 $(ProjectDir) 添加到应用程序的 Additional Include Directories 选项并将 "..\StdAfx.h" 替换为 "StdAfx.h" 来解决此问题，因为智能感知现在应该启动了拾取路径。

Answer 2

添加此内容是因为我在努力将 .pch 添加到项目时 post 阅读了此内容。

将 .pch 添加到现有项目时：如果你有 /include 和 /src 目录结构，它可能不起作用，除非你将“pch.h”和“pch.cpp”放在同一个目录 /src.

此外：将“pch.cpp”标记为 /Yc - 创建，并在要使用 .pch 的 .cpp 文件中将它们设置为 Yu - 使用。

#include “pch.h”作为 .cpp

中的第一个#include

注意。您需要为所有不包含它们的 .cpp 文件设置“不使用预编译头文件”。是的，这很麻烦。

VC++ 下的“附加包含目录”和一般“包含目录”都设置为我的 /include，当然 /src 在“源目录”中最初我希望 pch.h 和 pch.cpp 在 /include/pch/ 或 /src/pch/ 这应该有效。但我现在已经受够了痛苦，只是将它们都放在 /src/ 中 - 这确实有效。
