ERROR: Feature 'xcb' was enabled, but the pre-condition 'features.thread && libs.xcb && tests.xcb_syslibs && features.xkbcommon-x11' failed.

Additional context I have installed all the needed libs according to this page:https://doc.qt.io/qt-5/linux-requirements.html , except libxcd-xinerama-dev, which is unable to locate on my machine. Is there anything to do with this lib?

It seems that the package name in the qt documentation is wrong. Anyway, I installed libxcb-xinerama0-dev with this command: apt-get install libxcb-xinerama0-dev and problem is solved.

[JackBoosY]

Should we fix the required package name?

[chenpei2]

not sure, but I installed a full list of packages below to build qt5-base: libx11-dev libx11-xcb-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync0-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev libxcd-xinerama-dev (should be libxcb-xinerama0-dev on ubuntu 18.04) libxkbcommon-dev libxkbcommon-x11-dev @JackBoosY

[marshevms]

I can confirm that installing the above packages helped. BUT on Ubunutu 20.04:

 libxcb-sync0-dev is just libxcb-sync-dev
 libxcd-xinerama-dev is libxcb-xinerama0-dev

[MohamadHalwani]

I'm facing the exact same issue, and nothing here solved the issue ! Any suggestions ? Note: I'm using ubuntu 16.04 !

You are the man, thank you very much

So how can I install this dependences in rhel (my system version is 9.1)?

[silverqx]

Described here

sudo apt-get install build-essential perl python3 git
sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

You can use my example.
