Simple Qwidget application crash in debug environment [SOLVED]

  • Hi there,

    I just installed new Qt 5.5 (with mingw compiler) and created the simple QWidgets application. Only the basic window, no changes have been done.

    (New Project -> Application -> Qt-Widgets-Application)

    The application has been compiled, and after trying to debug it following crash occurred:

    :-1: Warnung: Eine Ausnahme wurde ausgelöst:
    Exception at 0x76f9d4f2, code: 0xc0000139: DLL entry point not found, flags=0x0.

    When I used the release build Test.exe in the deployment folder with the necessary Dlls it worked. But I guess in debug environment of QtCreator there is no need to copy the Dlls to every application build folder, or is it? The QtCreator 5.3 worked well, 5.4 and 5.5 are not.

    Do you have any ideas what could be wrong? I removed all Mingw and Qt installations, cleaned up the registry before installing 5.5 and used the default installation configuration.

    many thanks in advance.
