    Default Libraries, problems, external unresolveds..Steps to find the fix

    I have a third party libs. (msvc10) a MT/MD (Static cfgs's) and dynamic DLL cfg.
    I have qt + msvc10 express + win sdk.7

    They say that QT can only use this libs on "dynamic configuration" (what is dynamic configuration?)
    What it is supossed I have to use ? (I feel as a stupid newbie...)


    Ok , I use the existing examples offered, (using the libs) I can't compile ..... I have 4 unresolved external errors of the same lib.
    (But I have zero errors for the others)
    I have not support for these lib...... (but they are legal, I am a member without rights)

    Which are the steps to investigate a possible fix? Where I have to look ?
    Thanks.

    Did you tell your compiler you want it to link against this library? What does your Qt project file look like?
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    The project just use the typical LIB +L and -l.
    Apparently the other libs can be compiled...
    ( I say this because If I comment some lib I have 300 errors related to it)


    If I use the .dll's I have :
    fatal error LNK1107: invalid or corrupt file: cannot read at 0x2B8 ????


    So... Have I to use .lib or .dll ?
    Thanks....


    This is the QT project: (I hope you can view it well )
    My 4 errors are related with TD_ExamplesCommon.

    Maybe. The compiler claims your library (.lib) is corrupted.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    I have the solution.... (I receive help from the owners.)

    I link with the .lib's files but also I must to have the .dll's at the same folder than my executable.
    But.... I dont understand why it is possible?


    It seems that this variable is the guilty:

    DEFINES += _TOOLKIT_IN_DLL_

    But... I dont understand ....
    Static link is not automatic if you use .lib and dynamic if you use dll's ?

    Thanks Wy.
