I would say you are missing a development library here.
You can check the tests logs to see what has failed exactly.

I think so too.
Please ensure you've installed all the dependencies listed at https://doc.qt.io/qt-6/linux-requirements.html
Then, delete all the files generated through the configure/build process and try again.

Thanks @SGaist and @JKSH
It worked after I installed the following packages- Xcb-util-keysyms-devel.x86_64
- Xcb-util-renderutil-devel.x86_64
- Xcb-util-image-devel.x86_64
- Xcb-util-wm-devel.x86_64
- Xcb-util-cursor-devel.x86_64
- yum install libxcb libxcb-devel xcb-util xcb-util-devel
Listing the packages for future references :)

I have a similar problem to this (on RHEL 7.6 amd64) but without root access (and a very corporate IT that only does corporate IT things).
I've started building some dependencies that are too old/don't have dev packages installed (xcb, xcb-wm proto etc.).
Roughly what I've done is build these packages and then run configure with PKG_CONFIG_PATH pointing to their pkg-config directories.
However I still get
config.summary: xcb-sm ............................... no
I'm no expert in CMake. Can someone point out where this feature test gets logged?
-
configure -- --trace-expand seems to be what I need. Finding the failing test might be a bit of a challenge though as there is a huge amount of output.
So far I've built gperf, libxcb- x7 xorg- x4. If I have to build libxkbcommon then that will need meson and ninja.
