Like @SGaist said, you need the libraries anyway. Check Qt5 Dependencies page.
Try this maybe?

sudo apt-get install libx11-xcb-dev libglu1-mesa-dev build-dependencies

If not solves, try this,

sudo apt-get install libxcb1 libxcb-util0 libpam-dev libcairo-dev libxcb-xinerama0 libev-dev libx11-dev libx11-xcb-dev libxkbcommon0 libxkbcommon-x11-dev libxkbcommon-dev libxcb-dpms0-dev libxcb-xinerama0-dev libxkbfile-dev libxcb-util0-dev libxcb-image0-dev

Run the configure script that is located in qtbase.

As for xkbcommon, you can also disable that feature.

libraries
I installed this libs and started make. Now waiting a few hours ))) (it's quit slow)

This doesn't show where the build failed.

Re-run the build without the -j parameter so you'll see exactly were the error is.

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

I installed this libs

dev package also (which contains header files)?

[BrMisha]

@jsulm yes, libxkbcommon0 libxkbcommon-x11-dev libxkbcommon-dev are installed

[SGaist]

Did you re-run configure from a clean state ?

[BrMisha]

@SGaist I did re-unzip sources, then did configure))

[SGaist]

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

[BrMisha]

Log i will saw after do configure?

[SGaist]

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.

[SGaist]

Hi,

What version of xkbcommon do you have installed ?

[Pavel_47]

@closx said in How to build Qt on system without a GUI?:
I'm not aware what is actually installed ... I've just executed the following instruction, as was suggested previously in this topic (except libxcb-util0 which wasn't found)

sudo apt-get install libxcb1 libxcb-util0 libpam-dev libcairo-dev libxcb-xinerama0 libev-dev libx11-dev libx11-xcb-dev libxkbcommon0 libxkbcommon-x11-dev libxkbcommon-dev libxcb-dpms0-dev libxcb-xinerama0-dev libxkbfile-dev libxcb-util0-dev libxcb-image0-dev

@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.

[Pavel_47]

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 ...

[Pavel_47]

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 ?
