How to check if a Library file is available to the project or not ?
-
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, theLinktab, then add the library name in theProject Optionslist). Hope that helps. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

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)

Charting control [v1.2 - Updated]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.

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).

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, that was on VS6. On VS2003 (the one I have), you have to select menu
Project->Project propertiesthen theLinkernode and finally selectCommand lineand add the library name toadditional optionslist. :) Please note, actually names maybe a bit different, I translated from my version (Italian) one.If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

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
