使用 qmake/gcc 有条件地禁用警告? [英] Conditionally disable warnings with qmake/gcc?

问题描述

我参与了一个用 Qt 编写并在 Linux 上使用 qmake 和 gcc 构建的软件项目.我们必须链接到一个质量相当低并且会发出大量警告的第三方库.我想在我们的源代码上使用 -W -Wall，但是将 -w 传递给讨厌的第三方库，以保持控制台没有噪音和混乱，这样我们就可以专注于我们的代码质量.

I am involved with a software project written in Qt and built with qmake and gcc on Linux. We have to link to a third-party library that is of fairly low quality and spews tons of warnings. I would like to use -W -Wall on our source code, but pass -w to the nasty third-party library to keep the console free of noise and clutter so we can focus on our code quality.

在 qmake 中，有没有办法有条件地将 CFLAGS/CXXFLAGS 添加到某些文件和库中?

In qmake, is there a way to conditionally add CFLAGS/CXXFLAGS to certain files and libraries?

推荐答案

Jonathan，我认为问题在于您的源文件包含来自 3rd 方库的头文件，并且您想关闭后者的警告.

Jonathan, I think the problem is where your source files are including header files from 3rd party libraries, and you want to switch off the warnings for the latter.

Kevin，我认为您可以使用编译指示来控制警告:gcc 诊断编译指示

Kevin, i think you can use pragmas to control warnings : gcc diagnostic pragmas

您可以在任何#includes 之前和之后为 3rd 方库添加这些内容.

You could add these before and after any #includes for 3rd party libs.
