Library linking in Visual Studio Professional 2010

Question

I'm writing a C++ program using Chilkat library. I've linked the whole library to the project as follows:

project > properties > C/C++ > General > Additional Include Directories > C:\chilkat\include  (That's where I have the library)

AND

project > properties > Linker > Input > Additional Dependencies >  ...  C:\chilkat\libs\ChilkatDbgDll.lib; ...

Chilkat library came with 4 kinds of .lib files, each for different kinds of runtime, so I used the .lib which best suited my project (Multi-Threaded Debug DLL).

The damn thing still gives me this:

Any idea how to fix this? Thanks in advance.

If anybody is wondering how I fixed it: add Crypt32.lib and ws2_32.lib to additional dependencies (Linker > Input).

Answer 1

You're not linking the windows sockets import lib. Their library won't pull it in for you. It needs to be added to your linker-dependencies as well. It looks like their library is actually a static lib that expects your program to be linked as a MT DLL.

Add ws2_32.lib to your library list on your linker settings configuration (where you added your 3rd-party library).

Answer 2

It looks like you need to link to Ws2_32.lib which is the import library winsock.
