如何从库头压缩GCC警告？ [英] How to suppress GCC warnings from library headers?

问题描述

我有一个使用log4cxx，boost等库的项目，这些库的头文件会生成很多（重复）警告。有没有办法从库中包含警告（即#include ）或包含某些路径？我想在项目代码上像往常一样使用-Wall和/或-Wextra，而相关信息不被遮盖。我现在在make输出上使用grep，但是我想要更好的东西。

c $ c> -isystem 而不是 -I 。这将使他们成为系统标题，GCC不会为他们报告警告。

I have a project that uses log4cxx, boost, etc. libraries whose headers generate lots of (repetitive) warnings. Is there a way to suppress warnings from library includes (i.e. #include <some-header.h>) or includes from certain paths? I'd like to use -Wall and/or -Wextra as usual on project code without relevant info being obscured. I currently use grep on make output but I'd like something better.

解决方案

You may try to include library headers using -isystem instead of -I. This will make them "system headers" and GCC won't report warnings for them.
