    Hello all,
    I'm trying to replace a GUI in an old visual studio project.

    After install the Qt visual studio tools, and convert the old project to Qt VS Tools Project, I added a new Qt Class, simply to test that the new enviroment compile without problems. I'm thinking in replace that class with my gui after.

    but to begining, the new class don't fit with the old project,; I obtainthe linker errors below.

    I readed alle threads that I found, but can I not get it.

    please, any help will be wellcomed.

    When you use Qt classes you must also link against the Qt libraries.
