Yes, the error message told you which one: "features.xkbcommon &&
libs.xcb".
Since you have installed the XCB libraries, you should check for
xkbcommon
ones.
If you have libxcb1-dev installed, why are you passing -qt-xcb? And,
for
that
matter, why -qt-zlib? Just use your distro's packages for those.
Thanks Thiago for your reply,
xkbcommon is installed on the machine, version 0.4.1, but we still get
that
issue.
We are building qt with the -qt-xcb option to limit the number of
system
dependencies for our application.
You need version 0.5.0 at least.
From the ChangeLog [1]:
"
[QTBUG-65503] Removed xkbcommon from bundled sources. This library is
present on all supported platforms. The minimal required version now
is
0.5.0.
"
