    Hi!
    I'm trying to build static qt on Ubuntu. I built using this:

    ./configure -prefix /home/misha/Qt5_14_2_static -release -opensource -confirm-license -static -no-glib -no-pulseaudio -no-alsa -opengl desktop -nomake examples -nomake tests
    

    Then made simple gui project, but after start i got error:

    qt.qpa.plugin could not find the qt platform plugin "xcb" in ""
    

    Then i tried to build qt with xcb:

    ./configure -prefix /home/misha/Qt5_14_2_static -release -opensource -confirm-license -static -no-glib -no-pulseaudio -no-alsa -opengl desktop -nomake examples -nomake tests -qt-xcb
    

    But getting this:

    ERROR: Feature 'xcb' was enabled, but the pre-condition 'features.thread && features.xkbcommon && libs.xcb' failed.
    

    I tried to set direct link to xcb after "-qt-xcb" but it still doesn't want to configure.
    Help me, please)))

      Hi,

      You need the libxkbcommon development package for your distribution.

          Then check the test logs to see exactly what failed.

            Thanks, there is really something strange)))

            loaded result for library config.qtbase_gui.libraries.xkbcommon
            Trying source 0 (type pkgConfig) of library xkbcommon ...
            + /usr/bin/pkg-config --exists --silence-errors xkbcommon '>=' 0.5.0
            pkg-config did not find package.
              => source produced no result.
            Trying source 1 (type inline) of library xkbcommon ...
            xkbcommon/xkbcommon.h not found in [] and global paths.
              => source produced no result.
            test config.qtbase_gui.libraries.xkbcommon FAILED
            

            But /usr/include/xkbcommon/xkbcommon.h is exist. I can include it from qt creator. But why ./configure doesn't see that?

              A very similar discussion is taking place at: https://forum.qt.io/topic/114784/definitive-guide-to-building-source-from-downloaded-run-file/29

              No solution posted yet, though.

                Silly question but did you check that you have that file in your system ?

                    Did you install the package after calling configure ?
                    If so, did you call configure from a clean state ?

                          @SGaist - how to make a "clean slate" before running configure again?

                            See my note in this thread - I'm able to configure and build 5.14.0, but experience the same problem as @BrMisha with 5.14.2.

                                  The easiest is to do out of source builds so you can easily nuke the build folder to start anew.

                                    @BrMisha - I'm trying to build qt-everywhere-src-5.14.2 on ubuntu, having very similar problem with xcb that you report, i.e. "./configure -qt-xcb" gives errors. Are you also building qt-everywhere-src-5.14.2? How exactly did you overcome your problem and successfully build?
                                    Thanks!
