问题描述
我包括来自第三方库的文件，该文件引发可以降级为 -fpermissive 的警告的错误。但因为我不想污染我的编译日志与这些警告，我想完全禁用此消息。
I am including a file from a third-party library that raises an error that can be downgraded to a warning with -fpermissive. But because I do not want to "pollute" my compilation log with these warnings, I want to completely disable this messages.
到目前为止，我设置 -fpermissive 选项与当包括文件时;例如：
So far, I set the -fpermissive option with a diagnostic pragma when including the file; something like:
#pragma GCC diagnostic push
#pragma GCC diagnostic warning "-fpermissive"
#include <third-party-file.h>
#pragma GCC diagnostic pop
因为gcc通常提供 和否定版本的 -f 标志，我想到忽略不允许功能：
Since gcc usually provide both a "positive" and "negative" version of the -f flags, I thought about ignoring the "no-permissive" feature:
#pragma GCC diagnostic ignored "-fno-permissive"
#include <third-party-file.h>
但是似乎没有否定版本的 fpermissive 标志（我使用gcc 4.6.3;但是即使是4.7.0版本）。
But there does not seem to be a "negative" version of the -fpermissive flag (I am using gcc 4.6.3; but even the version 4.7.0 does not have it).
任何机会，我可以模仿这种行为吗？
Any chance I can mimic this behavior? Thanks!
推荐答案
这可能有点晚了，但其中一个应该做你想要的：
It's maybe a bit late for this, but one of these ought to do what you wanted:
#pragma GCC diagnostic ignored "-fpermissive"
或
#pragma GCC diagnostic ignored "-pedantic"
ignored是如何彻底压制诊断程序，以及 -fpermissive 是 -pedantic ，因为历史原因。
"ignored" is how you squelch a diagnostic entirely, and the inverse of -fpermissive is -pedantic, for historical reasons.
