How to check if a Library file is available to the project or not ?

Nikhil Trivedi

Hello All, I have included the directory containing ws2_32.lib to the project in the Library files' directory. Now I am getting LNK2019 error which says that the function I am using from winsock2.h are unresolved externals. So I want to check whether my project is having the ws2_32.lib file available or not ? How can I check ? If someone knows please help me. Thanks for the prompt reply. Nikhs Nikhil Trivedi

You need also to specify in your project settings that you want to link against this library. This is done in 'Linker' -> 'Input' -> 'Additional Dependencies' (for VS2005).

you have to add the library to the linker input libraries (select, in menu Project->Settings, the Link tab, then add the library name in the Project Options list). Hope that helps. :)

If you are using of vs2005 it installed library files(necessary ) on your machine but anyway You can add this code to your source file

#pragma comment(lib, "Ws2_32.lib")

Whats your application type?(Console)

I didn't find anywhere Linker option. I am using Visual studio 2005. It is not in Project tab and not even in Tools->options tab where we can add the directory paths Can you tell me where to add the library file in Visual Studio 2005? Thanks for prompt reply. Nikhs Nikhil Trivedi

Thanks for your reply. But that is with visual studio 6.0. I know that. But I have just upgraded to Visual studio 2005. Can you tell me how to add the library file in that one ? Thanks for prompt reply. Nikhs Nikhil Trivedi

Yes it is: you need to have a project opened and then you will have a menu '.... Properties' (where '....' is the name of your project).

Yes, that was on VS6. On VS2003 (the one I have), you have to select menu Project->Project properties then the Linker node and finally select Command line and add the library name to additional options list. :) Please note, actually names maybe a bit different, I translated from my version (Italian) one.

I think you asked and I answered to you did you see my previous message?

Go 'Project' -> 'Project Properties' -> open 'Configuration Properties' -> open 'Linker' -> open 'Input' -> add the .lib file to 'Additional Dependencies'.

Heh :) I add them in Project properties->Linker->Input->Additional Dependencies. The last time I mentioned that, somebody reminded me you can just add it to the tree in solution explorer LOL Cheers, Mark
