如何在Visual C ++中禁止显示外部标头中的警告 [英] How to suppress warnings in external headers in Visual C++

问题描述

我正在开始一个新的BREW项目，并且我希望使用警告级别4(/W4)进行编译，以保持应用程序代码的美观和整洁.问题在于BREW标头本身无法使用/W4干净地编译.

I'm starting a new BREW project, and I'd like to compile with Warning Level 4 (/W4) to keep the application code nice and clean. The problem is that the BREW headers themselves don't compile cleanly with /W4.

在gcc中，您可以使用-I和-isystem来区分应用程序标头和系统标头，然后默认情况下，gcc不会在系统标头中报告任何编译警告.在Visual C ++中有等效的机制吗?

In gcc you can differentiate between application and system headers by using -I and -isystem, and then by default gcc doesn't report any compilation warnings in system headers. Is there an equivalent mechanism in Visual C++?

推荐答案

仅在无法更改但需要包括的标头块周围使用此方法.

Only use this method around a block of headers that you cannot change, but that you need to include.

您可以有选择地暂时禁用所有警告，例如:

You can selectively, and temporarily disable all warnings like this:

#pragma warning(push, 0)        
//Some includes with unfixable warnings
#pragma warning(pop)

您可以选择传入警告编号来禁用它，而不是0，例如:

Instead of 0 you can optionally pass in the warning number to disable, so something like:

#pragma warning( push )
#pragma warning( disable : 4081)
#pragma warning( disable : 4706 )
// Some code
#pragma warning( pop )
