IRC winsock DLL的问题 [英] Issues with IRC winsock DLL

问题描述

当我尝试使用winsock代码编译DLL时，问题相当简单，它会产生大量错误。当它被编译为控制台应用程序并且为什么超出我的原因时，这不会发生。如果有人有建议，请给它。



以下一小部分

我尝试过：



根据关于此主题的其他主题移动包含。

解决方案

始终包含 winsock2.h windows.h 之前（或者只是删除 windows.h 包括 winsock2.h ）。

The issue is rather simple when I try to compile a DLL with winsock code it produces a huge number of errors. This does not happen when it is compiled as a console app and reason as to why are beyond me. If anyone has advice please give it.

A small fraction of them below

What I have tried:

Moving the includes around in accordance with other threads made on this subject.

解决方案

Always include winsock2.h before windows.h (or just remove including of windows.h because it is included by winsock2.h).
