    Hi,
    I compiled Qt5 version (5.12.10) from git repository with various modules (including systems and x11) on Kubuntu 14.
    I used this version as SDK for my application and it compiled successfully.
    My application pack all needed libs as a package and is not using libs installed on system.
    When I tried to run the application, I got error message that I am missing xcb plugin.
    And it was missing as a plugin and as libqxcb.so in my compiled Qt5 libs.
    I tried to find information on how to compile this plugin / .so , but I couldn't find anything.
    Any help will be appreciated.

      During configure stage the summary output shows you if the xcb plugin gets compiled or not. In config.log you can see why it may not be compiled.

        Thanks for answer.
        In the log I didn't found the reason why it didn't compiled.

        But during configure I can see that I am missing some system libs for qpa-xcb. I am not sure that qpa-xcb = libqxcb.so, but I will try to resolve my missing system libs and update if it helped.

          Apparently my system libs didn't matched requirements,
          I think I can't build this version on Kubuntu 14 without "stitching" these system libs,
          So I ended up building lesser (5.9) version.

            @Alex_Kr said in Qt5 xcb plugin compilation:

            Kubuntu 14

            This is a 7 years old distribution without any support (not even security patches)!
            I would say it's time to upgrade :-)
