如何在 GCC 中摆脱“已弃用的从字符串常量到‘char*’的转换"警告?

How to get rid of `deprecated conversion from string constant to ‘char*’` warnings in GCC?(如何在 GCC 中摆脱“已弃用的从字符串常量到‘char*’的转换警告?)

问题描述

所以我正在处理一个非常大的代码库，最近升级到 gcc 4.3，现在触发了这个警告:

So I'm working on an exceedingly large codebase, and recently upgraded to gcc 4.3, which now triggers this warning:

警告:不推荐将字符串常量转换为‘char*’

warning: deprecated conversion from string constant to ‘char*’

显然，解决这个问题的正确方法是找到每个声明，如

Obviously, the correct way to fix this is to find every declaration like

char *s = "constant string";

或函数调用，如:

void foo(char *s);
foo("constant string");

并使它们成为 const char 指针.但是，这意味着最少要接触 564 个文件，这不是我目前希望执行的任务.现在的问题是我使用 -werror 运行，所以我需要一些方法来抑制这些警告.我该怎么做?

and make them const char pointers. However, that would mean touching 564 files, minimum, which is not a task I wish to perform at this point in time. The problem right now is that I'm running with -werror, so I need some way to stifle these warnings. How can I do that?

推荐答案

我相信将 -Wno-write-strings 传递给 gcc 会抑制这个警告.

I believe passing -Wno-write-strings to gcc will suppress this warning.
