    The log is huge.
    I scrolled up a few hundred lines - nothing that indicatedŝ errors.
    Concerning text instead of screenshots - Ok, I took note.

      Run the build with only one process you'll have the error closer.

        Yes, with one core the the log is more verbose.
        Here is what I got at the end:

          You're not linking against xkb lib

              @Pavel_47 Try

              file /home/pavel/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libxkbcommon.so
              

              and post the output here.

                      I've just checked libxkbcommon-dev and libxkbcommon-x11-dev on RPi. As on Ubuntu they are installed and are newest versions.

                      So sync them to your sysroot in the host PC!

                      As on Ubuntu they are installed and are newest versions.

                      Forget about that, it doesn't matter.

                      For cross-compilation you need your libraries + headers installed properly in target device (RPi), then copy (synchronize) some folders from your target device into the sysroot folder in your host PC (with Ubuntu) and only then attempt to build (Qt framework, modules, your application).

                        I proceeded exactly as described on the page you mentioned.
                        Sure I performed the resync with RPi

                          I'm not going to argue in contrary, so your next task is to figure out why even having rsync'd the file is missing from your sysroot folder...

                              The file isn't missing. It's there:

                              Well, it's somewhere else but not in the expected location it seems...

                              /home/pavel/pavel/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libxkbcommon.so.0.0.0

                              is different from the location in your last post (again, please stop posting screenshots!)

                              /home/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libxkbcommon.so.0.0.0

                                Sorry, I've been mistaken while executing:
                                file /home/pavel/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libxkbcommon.so.0.0.0

                                the correct result is here:

                                pavel@ALABAMA:~/raspi/qtbase$ file ~/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libxkbcommon.so.0.0.0
                                /home/pavel/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libxkbcommon.so.0.0.0: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=ca40d4cec17c0cb8d6a85dcefc44fc89ac706d41, stripped

                                  I contacted Ran Benita, the developer of xkbcommon package, and exposed him the problem. After some checks on my system, here is his conclusion:

                                  "The version of libxkbcommon you have in your arm-linux-gnueabihf raspi/sysroot is very very old. Qt requires a newer version. You should update your cross-compilation environment to something more recent."

                                  Where /home/pavel/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libxkbcommon.so comes from ?

                                    @Pavel_47 said in How to build Qt on system without a GUI?:

                                    From your Raspberry Pi when you're syncing it...
                                    What exact OS (including version) do you run on it?

                                        @Pavel_47 You can try to upgrade to current Raspbian version and then recreate your sysroot.

                                          Well ... I did it just before resync. Then, as I remember, after some manipulations with other staff, system proposed to remove unused files ... and I did it. Ok, I'll try to upgrade one more time. Then what should I check on RPi3, that xkbcommon package is latest version ?
