load plugin Qt/Tools/QtCreator/lib/Qt/plugins/platforms/libqxcb.so

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)
qt.core.plugin.loader: QLibraryPrivate::loadPlugin failed on "/home/grafeno30/Qt/Tools/QtCreator/lib/Qt/plugins/platforms/libqxcb.so" : "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)"
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
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

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

The -dev is not needed for running Creator.
