如何链接包含htonl，ntohl和amp;的库在VC ++ 2017中的ntohs？ [英] How to link library containing htonl, ntohl & ntohs in VC++ 2017?

问题描述

我收到错误消息，例如

 1> dsim.obj：错误LNK2019：未解析的外部符号__imp__htonl @ 4在函数中引用unsigned short __cdecl AddEthCard（unsigned int，unsigned char *，char *，struct pcap *）（？AddEthCard @@ YAGIPAEPADPAUpcap @@@ Z）
 1> dsim.obj：错误LNK2019：未解析的外部符号__imp__ntohl @ 4在函数void __cdecl HandleIGMPMsg（struct ethcard *，struct pcap_pkthdr *，unsigned char *）中引用（？HandleIGMPMsg @@ YAXPAUethcard @@ PAUpcap_pkthdr @@ PAE @ Z）
 1> dsim.obj：错误LNK2019：函数void __cdecl HandleARPMsg（struct ethcard *，unsigned char *）中引用了未解析的外部符号__imp__ntohs @ 4（？HandleARPMsg @@ YAXPAUethcard @@ PAE @ Z）

我找到了关于它的消息，并知道它需要链接ws2_32.lib。我做的是：

1.在链接器中添加ws2_32.lib到附加依赖项 - >输入。

2.添加包含ws2_32.lib的文件夹的路径Linker的其他图书馆目录 - >将军。



我的问题是：

1.我错过了添加ws2_32的任何内容.lib解决未解决的问题？

2.我发现很多文件夹包含ws2_32.lib，如下所示，我应该选择哪一个？目前，我选择了

我尝试过在网络上找到的方法，但问题仍然存在。
解决方案
 我将库目录从
 C：\Program Files（x86）\ Mysrosoft SDKs \ Windows \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ p $ p> C：\Program Files（x86）\ Microsoft SDKs \ Windows \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ BR /> 
I've got error message like

I found message about it and know that it needs to link ws2_32.lib. What I did is:

1. Added ws2_32.lib to "Additional Dependencies" in Linker->Input.

2. Added path of folder containing ws2_32.lib into "Additional Library Directories" at Linker->General.



My questions are:

1. Anything I missed to do for adding ws2_32.lib to resolve the unresolved issues?

2. I found lots of folders containing ws2_32.lib as below, which one should I choose? Currently, I chose 
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64




C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64
C:\Program Files (x86)\Windows Kits\10\Lib\10.0.10240.0\um\arm
C:\Program Files (x86)\Windows Kits\10\Lib\10.0.10240.0\um\arm64

C:\Program Files (x86)\Windows Phone Kits\8.0\lib\ARM
C:\Program Files (x86)\Windows Phone Kits\8.0\lib\x86




What I have tried:



I tried ways which I found at networks but problem remains.
解决方案
I changed library directory from 
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64
 to 
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib
, all such kinds of linking errors were gone.
