    Question Linker not finding socket functions?

    I'm trying to Build a program that uses sockets to communicate with another program, but when I get to the link portion of the build, I get the following errors:
    Code:
    Linking...
    BAESocket.obj : error LNK2001: unresolved external symbol __imp__WSAGetLastError@0

    BAESocket.obj : error LNK2001: unresolved external symbol __imp__gethostbyaddr@12
    Debug/FTI_SCU.exe : fatal error LNK1120: 19 unresolved externals
    Error executing link.exe.
    My BAESocket class references the listed functions, minus the __imp__ (e.g., my function calls htons() vice __imp__htons()).

    I've tried adding ws2_32.lib to the "additional library path" field in the Input Category of the Link Tab in Project Settings without luck.

    What do I need to do to get my program to link?

    You need to add it to the object/librarys modules entry, not the additional path, that is just a path setting for the above.

    or use
    #pragma comment(lib,"ws2_32")

    in code.

    Thumbs up

    Thank you. I thought I tried that before, but that was on something else, apparently.
