Qt Widget Applications will not compile and run

  • I just started using Qt, and for some reason whenever I make a Qt Widget Application project, I get this error:

    Configuration is faulty. Check the Issues view for details.
    Error while building/deploying project TestCppGame (kit: Desktop Qt 5.6.0 MSVC2015 64bit)
    When executing step "Make" 

    However, I do not get any error when running Qt Console Applications. I checked the kit setup and it is the same for both. I am using Microsoft Visual C++ Compiler 12.0 and CMake3.6

    What can you see in "Compile Output" and "Issues" tabs in QtCreator?

    Hi and welcome to devnet,

    Visual C++ Compiler 12.0 comes from Visual Studio 2013. You installed Qt for Visual Studio 2015 so you have two solutions:

    1. Install Visual Studio 2015
    2. Install Qt for Visual Studio 2013

    On Windows you can't mix and match compilers, they are not compatible one with the other. Nothing Qt specific.
