    Today I installed qt 6.1 in my PC (red hat 8),so after finishing downloading and pressed on finish button ,default qt creator should open but it didn’t open ,so I tryed to open from my terminal and I getting this warning message and getting Abort

    Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway. 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.

    Can anyone please solve this problem for me,thanks in advance .

      @nikhilsarma
      Try Googling the error message, plenty of hits: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland.

      If that doesn't resolve, set environment variable QT_DEBUG_PLUGINS=1 and then run program, look at end of the diagnostic output you get.

          Your log says that libxcb-icccm.so is missing. So the solution is to install the missing library.

              There is no other solution.
              What exactly did you install and how (what is the name of the package you installed?)?
              Did you check whether you have libxcb-icccm.so ("find /usr -name libxcb-icccm.so")?

                  @nikhilsarma What does

                  find /usr -name libxcb-icccm*

                  output?

                  Also

                  Installed:
glibc-2.28-72.el8_1.1.i686 libXau-1.0.8-13.el8.i686 libxcb-1.13-5.el8.i686
xcb-util-wm-0.4.1-12.el8.i686

                  indicates that x86 packages were installed, not x86_64 which is strange.

                    @nikhilsarma said in Installation error:

                    Wrong architecture, like @jsulm said. You want to install x86_64 packages, not i686 packages.

                    Uninstall these 32-bit packages and try again.
