我正在努力清理我的代码，将一些部分移动到.h和.cpp文件中。

问题是，当我试图编译时，我会得到一个“已经定义”的错误。

我知道有几个类似的问题。但是我已经检查过好几次了，我没有看到任何重复的定义，也看不到它的位置以外的任何东西。找不到问题出在哪里。

这是一个dll代码：

代码语言：javascript

如何正确使用.h和.cpp文件来避免此错误？

编辑：( @AleXelton )建议我从functions.cpp中删除#include "includes.h"，编译时如下所示：

functions.h声明了一组全局变量。任何包含.cpp (即，通过包含includes.h)的文件都将得到这些变量的自己的副本。因此，当链接器试图将编译后的单元合并到最终的可执行文件中时，就会出现“已经定义”的错误。

如果您的目标是在.cpp文件之间共享这些变量，则需要在functions.h文件中将这些变量声明为extern，然后在functions.cpp中定义实际变量，例如：

Functions.h
