错误MIDL2003:重新定义:IMyInterface [英] error MIDL2003: redefinition : IMyInterface

问题描述

我正在修改MFC项目odl文件以添加新接口ILayer，但是该文件已经存在于其他项目中，因此在构建所有项目时，我会收到与重新定义相关的错误.如下:

推荐答案

回答了您自己的问题.如果ILayer已经存在于其他地方，为什么还要重新定义它.可以使用唯一名称定义它，也可以使用现有名称.

You have pretty much answered your own question. Why are you redifining ILayer if it already exists elsewhere. Either define it under a unique name, or use the existing one.
