ftpclient.h与windef.h冲突声明 [英] ftpclient.h conflicting declaration with windef.h

问题描述

你好，



我从这个网站下载了这个宏伟的类，但是当我要编译项目时，我收到一个编译错误说：

Hello,

I downloaded this magnificent class from this web, but when I'm going to compile the project I get a compilation error saying:

Definements.h:42:25: error: conflicting declaration ‘typedef unsigned int DWORD'
windef.h:117:27: error: ‘DWORD’ has a previous declaration as ‘typedef long unsigned int DWORD’
Definements.h:45:25: error: conflicting declaration ‘typedef unsigned int ULONG’
windef.h:25:27: error: ‘ULONG’ has a previous declaration as ‘typedef long unsigned int ULONG’

这些是我的包含：

These are my includes:

#include <string>
#include <windows.h>
#include <FtpClient.h>
#include <sstream>
#include <fstream>
#include <iostream>
#include <stdio.h>
#include <cstdlib>

我不知道我能做些什么。欢迎任何解决方案。



非常感谢！

I'm not sure what can I do. Any solution is welcome.

Thank you very much!

推荐答案

编辑 .h 发生重复错误的文件。



用包装重复的声明#ifndef 和 #endif 。



示例

Edit the .h file where the duplicate error occurs.

Wrap the duplicate declaration(s) with #ifndef and #endif.

Example

#ifndef 
typedef unsigned int DWORD
#endif

根据此表数据类型范围 [ ^ ]，这两个定义是兼容的，因此您可以安全地遵循 Mike Meinz 的建议并保留其中一个。

According to this table Data Type Ranges[^], the two definitions are compatible, hence you may safely follow Mike Meinz's advice and keep just one of them.
