PCH Warning: header stop cannot be in a macro or #if block - Visual C++ 2010 Express SP1
提问by pighead10
This is pasted from a website, which presumably was working. I did some googling and found that the issue I have now is a result of Visual C++ 2010 SP1, which I downloaded today, and is now giving me this error:
这是从一个网站粘贴过来的，该网站可能正在运行。我做了一些谷歌搜索，发现我现在遇到的问题是我今天下载的 Visual C++ 2010 SP1 的结果，现在给了我这个错误：
PCH Warning: header stop cannot be in a macro or #if block.
PCH Warning: header stop cannot be in a macro or #if block.
Hopefully someone will be able to help me with this!
希望有人能够帮助我解决这个问题！

I had the same issue and was looking for a solution. Following worked for me:
我遇到了同样的问题，正在寻找解决方案。以下为我工作：
Add #pragma onceat the start of the file (even before the #ifndef APP_STATE_Hheader guard)
添加#pragma once在文件的开头（甚至在#ifndef APP_STATE_H标题保护之前）

You probably used a project template to get started and threw away the pre-generated source code files. Those project templates like to turn on precompiled headers because it is such a time-saver. Right-click your project in the Solution Explorer window, Properties, C/C++, Precompiled Headers. Change the "Precompiled Header" setting to "Not Using".
您可能使用了一个项目模板开始并丢弃了预先生成的源代码文件。那些项目模板喜欢打开预编译头，因为这样可以节省时间。在解决方案资源管理器窗口中右键单击您的项目、属性、C/C++、预编译头文件。将“预编译头”设置更改为“不使用”。

I had the same problem. My solution was to add a missing ';' at the end of a class definition. Although this does not seem to apply to your problem, others who come here with the same error might find this helpful.
我有同样的问题。我的解决方案是添加一个缺失的 ';' 在类定义的末尾。尽管这似乎不适用于您的问题，但其他遇到相同错误的人可能会发现这很有帮助。

I found that my .h file was actually being treated as a .cpp file! Right click on the file in the Solution Explorer > All Configurations > Item Type: C/C++ header
我发现我的 .h 文件实际上被视为 .cpp 文件！右键单击解决方案资源管理器中的文件 > 所有配置 > 项目类型：C/C++ 标头
Make sure the item type is not C/C++ compiler or other.
确保项目类型不是 C/C++ 编译器或其他类型。

This is probable a day late and a dollar short but I had the same error when I accidentally put my header file in a .cpp file instead of a .h file. I will post it though in case it can help someone.
这可能是晚了一天和一美元的空头，但是当我不小心将头文件放在 .cpp 文件而不是 .h 文件中时，我遇到了同样的错误。我会发布它，以防万一它可以帮助某人。

I just added a referenct to the header file (#include "header.h") and it helped.
我刚刚向头文件（#include“header.h”）添加了一个引用，它有帮助。
回答by codyj110
Once you add a .cpp file and have it include the header this error should go away. I've read some where else this is a bug.
一旦你添加了一个 .cpp 文件并让它包含标题，这个错误就会消失。我读过一些其他地方这是一个错误。
