        Did you re-run configure from a clean state ?

            Can you check the configure log to see if there's anything related to that ?

                They are generated when configure is run. Look into your build folder.

                  Hello,
                  I've tried all suggestions found on this topic, but build process still fails: cannot find xkbccommon-compose.h file. Just one remark: trying to install additional packages with the command:
                  sudo apt-get install libxcb1 libxcb-util0 libpam-dev ...
                  I should remove just libxbc-util0 (all others were kept) because this package wasn't found.
                  Any ideas ?
                  Thanks.

                    Hi,

                    What version of xkbcommon do you have installed ?

                        @Pavel_47 Did you install these packages on your target device? Since you're crosscompiling you need them in your sysroot, not on your host machine.

                          I've contacted libxkbcommon developers. They suggested me using this command:
                          sudo apt-get install libxkbcommon-dev libxkbcommon-x11-dev
                          That is what i did, but system informed me that libxkbcommon-dev and libxkbcommon-x11-dev are already the newest versions (i.e. 0.8.2-1~ubuntu 18.04.1).

                          Well, I'm trying to rebiuild Qt toolchain once more . Now it's running ...

                            Sorry, I've missed your last suggestion - install libxkbcommon on target (i.e RPi3 in my case). But anyway, how build process on the host can be influenced by what is installed (or not) on that target device ?

                              The new attempt of Qt building is also failed.
                              I wonder if anyone has managed to bulid Qt on Ubuntu ?
                              What should I check ... or install to resolve the problem ?

                                Since you are cross-compiling, you need all dependencies for your target. This is usually done installing the libraries on said target and then sync the content of the file system of the target back to the host so the cross-compiler can use them to do its work.

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

                                    Did you sync your RPi filesystem back to your host before trying to build Qt ?

                                      Yes, at very first time I executed these commands (as it's suggested here https://wiki.qt.io/RaspberryPi2EGLFS):
                                      rsync -avz pi@raspberrypi.local:/lib sysroot
                                      rsync -avz pi@raspberrypi.local:/usr/include sysroot/usr
                                      rsync -avz pi@raspberrypi.local:/usr/lib sysroot/usr
                                      rsync -avz pi@raspberrypi.local:/opt/vc sysroot/opt

                                      Then I did 3 or 4 other attempts to build, but at each of these attempts I didn't proceed with resync with RPi.
                                      Anyway one thing escapes me .... should I keep connection with RPi while running toolchain build on host ?

                                        No, you just need to sync your sysroot.

                                          I've checked the location of xkbcommon-compose.h. It's Ok:
                                          alt text
                                          Then I've tried to compile this:

                                          #include <xkbcommon/xkbcommon-compose.h>
                                          int main() {}
                                          

                                          It was also Ok
