fatal error: xkbcommon/xkbcommon-compose.h: No such file or directory

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

This man had like problem. He wrote that built qtbase, bu HOW??? I can't find info about it on network

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 ?

@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 ?

Pavel_47

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 ?
