我有一个客户端代码文件，包含三个不同对象类型的三个.h文件（UnsortedType，CompData，ItemType）。 UnsortedType.h也有一个#include ItemType.h
在包含客户端代码的标头保护和UnsortedType文件中的相同保护之后，我留下的唯一错误是函数ObjectFromFile的模糊编译错误。 当我注释掉这个函数时，我得到了UnsortedType和ItemType数据的几个Undefined错误，所以我觉得还有其他的事情发生了。
此程序用于从inFile对象ItemType项中引入数据，转换为特定格式并检查有效性，然后将数据添加到UnsortedType的特定列表，具体取决于 数据的某些方面。 （有效，无效，RAM和磁盘大小，笔记本电脑数据，桌面数据）。
这是我的错误：
runItemType.cxx: In function âUnsortedType ObjectFromFile(std::ifstream&, UnsortedType&, CompDataType, ItemType&, UnsortedType&, UnsortedType&, UnsortedType&)â:
runItemType.cxx:215: error: âCompareRAMAndDiskâ was not declared in this scope
这是我的客户代码：

欢迎任何帮助！ （另外，如果你看到逻辑错误，请告诉我！我一般可以自己修复它们，但是我越快完成它就越好！）

你的功能声明是：
void CompareRAMAndDisk(ItemType item, UnsortedType& RAMList);
，您的函数定义是：
void CompareRAMAndDisk(ItemType item, UnsortedType RAMList);
看到区别？从它的外观来看，您想要将功能定义更改为使用UnsortedType &。

主要问题是我的编译方式; 我已经解决了这个问题。
