这种情况下,编译器就会出现“multiple definition of枚举”的错误。 那么,如何解决这个多个定义的问题呢?以下是几种常见的解决方法。 1.使用命名空间(Namespace) 命名空间是一种将全局作用域划分为不同区域的机制。通过将枚举定义放置在不同的命名空间中,可以确保不同的定义不会发生冲突。例如: ```cpp namespace ...
#include "xxx.h"引用了本地没用的头文件,该头文件中和现有文件中多次定义了该枚举值
so such folks will have only seen it by looking at the source code. Such folks will be knowledgeable enough to fix their code if the name of the enum changes.

multiple-definition 在GCC编译报错里面,它的报错本质是 重复定义,可能是函数重复定义,也可能是变量重复定义。 但今天我要介绍的这个 multiple-definition 跟常规遇到的还不太一样,否则这个问题就不值得我写篇文章来做记录了,详细请看下文。 2 问题描述
