    Hello,

    when I run ./qtcreator (before I use export QT_DEBUG_PLUGINS=1). I get the next message:

    qt.core.library: "/home/grafeno30/Qt/Tools/QtCreator/lib/Qt/plugins/platforms/libqxcb.so" cannot load: Cannot load library /home/grafeno30/Qt/Tools/QtCreator/lib/Qt/plugins/platforms/libqxcb.so: (libxcb-cursor.so.0: cannot open shared object file: No such file or directory)

    This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
    
    Available platform plugins are: wayland-egl, xcb, eglfs, linuxfb, offscreen, minimalegl, wayland, minimal, vnc, vkkhrdisplay.

    grafeno30@linuxLaptop:~/Qt/Tools/QtCreator/bin$ ldd /usr/lib/qt/plugins/platforms/libqxcb.so
    ldd: /usr/lib/qt/plugins/platforms/libqxcb.so: No such file or directory
    
    

    I cannot run QtCreator.

    Thanks in advance.

      And, does libqxcb.so exist there? Or for that matter elsewhere? Have you done a system install like

      # at least one of these
      sudo apt-get install libxcb-cursor-dev
      sudo apt-get install libxcb-cursor

        @JonB @grafenocarbono

        For me it was: sudo apt install libxcb-cursor0 (with trailing zero)

        The -dev is not needed for running Creator.

        Qt has to stay free or it will die.
