Question

我遇到了一种情况，因为我把文件拆分了，因为我觉得它太大了，所以无法编译程序。一旦文件全部合并为一个，它就完美无缺。现在我拆分了它们，编译器给了我以下错误：

这让我发疯了。当我拆分它时，我无法使这些工作。而且我觉得它更有条理，我真的想做。

我要处理这些文件，所以你们可以查看是否需要。

Answer 1

文件include\allegro\alcompat.h似乎多次定义相同的符号（fnt_datafile，snd_datafile），无论您将其包含在何处。

如果这些都是全局变量，则应在标题中声明extern并在单个实现文件中定义。

如果它们是方法，则应将其声明为inline。

当只有一个文件时它起作用，因为这意味着只有一个翻译单元导出这些符号。

Answer 2

尝试在头文件的开头添加保护，例如#pragma once，因此在编译期间不会#included多次。

或者，您可以指定

#ifndef _SNAKE_GAME.H // or any label you want 
#define _SNAKE_GAME.H
//All other code of header file goes here
#endif

Answer 3

每个文件可能都不包含他们需要的所有内容有了一个大文件，所有内容都会看到所有包含。

您可能需要在每个spitted文件中添加缺少的包含。

包含指令弄乱程序
