如何解决链接器错误:未解析的外部符号 [英] How to solve linker errors: unresolved external symbol

问题描述

我没有Unicode库，因此我尝试编译发行"版本.一切都编译到最后一步；演示.然后我得到了这些错误.我错过了什么吗?

I don''t have the Unicode library so I tried compiling the "Release" version. Everything compiled until the last step; the demo. Then I got these errors. Did I miss something?

推荐答案

它看来您需要链接到libDCR库[ ^ ](我想是Ws2_32.lib和htons函数的Ws2_32.lib).
:)

It looks like you need to link with the libDCR library [^] (and the Ws2_32.lib for the htons function, I suppose).
:)

在以下情况下可能会发生此问题:

1.缺少某些库.[确保所有库都包含在
中 其他包含库"].
2.确保您已为附加包含库"设置了路径.
3.确保您已包含相关的头"文件..
4.确保您使用的版本正确的dll用于发布"版本.



谢谢

Hi,

The problem can occur in the following cases:

1. Missing some library.[Make sure that all the Libraries are included in
"Additional Include Libraries"].
2. Make sure u have set path for Additional Include Libraries.
3. Make sure u have included concerned "header" files..
4. Make sure u are using the right version of dll for the "Release" build.



Thanks

标题声明后的顶部.

At the top after header declaration.

#pragma comment (lib, "fully qualified path to libdcr");

//其他放在system32中

可能会起作用

//else put in system32

May be this will work
