fpermissive 标志有什么作用? [英] What does the fpermissive flag do?

问题描述

我只是想知道 -fpermissive 标志在 g++ 编译器中的作用是什么?我得到:

I'm just wondering what the -fpermissive flag does in the g++ compiler? I am getting:

错误:取临时地址[-fpermissive]

error: taking address of temporary [-fpermissive]

我可以通过向编译器提供 -fpermissive 标志来解决这个问题.

which I can solve by giving the -fpermissive flag to the compiler.

编辑:我刚刚找到了导致临时地址错误部分的原因！我现在就去修复那个部分.

EDIT: I just found what was causing the temporary address error part! I'm going to fix that part right now.

推荐答案

来自 文档:

-fpermissive
将一些关于不符合代码的诊断从错误降级为警告.因此，使用 -fpermissive 将允许编译一些不合格的代码.

-fpermissive
Downgrade some diagnostics about nonconformant code from errors to warnings. Thus, using -fpermissive will allow some nonconforming code to compile.

底线:不要使用，除非您知道自己在做什么！

Bottom line: don't use it unless you know what you are doing!
