    Default Help - LNK2019: Unresolved external symbol

    Hi.
    My setup is windows 7 and compiling using QTCreator.
    I got this error.
    mainwindow.obj:-1: error: LNK2019: unresolved external symbol

    I think it has something to do with an external library? How do I link the library?

    Thanks.
    Marc

    You can start by searching the forum for similar issues (I mean linking libraries and not LNK2019).

    With the correct additions to the LIBS variable in your PRO file. This topic has been covered many times in this forum.

    "QTCreator" is not a compiler, it is an IDE. Your compiler is Microsoft's VC++ and its linker.

    No. Use the "Preview Post" or "Go Advanced" button
