Project ERROR: Unknown module(s) in QT: waylandclient-private

ybakos

I've just now tried opening the qtwayland project in Qt Creator again for the first time since trying to build from the command line.

The good (?) news is that the only error I am seeing in the General Messages are:

[Inexact] Project MESSAGE: perl -w /home/ybakos/Qt/5.8/gcc_64/bin/syncqt.pl -module QtWaylandClient -version 5.8.1 -outdir /home/ybakos/projects/build-qtwayland-Desktop_Qt_5_8_0_GCC_64bit-Debug /home/ybakos/projects/qtwayland
[Inexact] Project MESSAGE: perl -w /home/ybakos/Qt/5.8/gcc_64/bin/syncqt.pl -module QtWaylandCompositor -version 5.8.1 -outdir /home/ybakos/projects/build-qtwayland-Desktop_Qt_5_8_0_GCC_64bit-Debug /home/ybakos/projects/qtwayland

Project ERROR: Library 'xkbcommon_evdev' is not defined.

To my knowledge, xkbcommon_evdev isn't a separate library... how can I squelch this error? I feel like this is somehow related to my build issue.

SGaist

Do you have a QMAKE_USE= somewhere ?

ybakos

@SGaist My apologies, but I'm not familiar with that config var. Where/how do I use it?

SGaist

Sorry, I was talking about the sources of the module.

ybakos

@SGaist There are QMAKE_USE declarations throughout the various .pro files. For example:

QMAKE_USE += wayland-client wayland-server

In ivi-shell.pro, compositor.pro, and wayland_wrapper.pri I do see:

QMAKE_USE += xkbcommon_evdev

SGaist

Comment that one and you should be able to go further.

ybakos

@SGaist Thank you (again) but I've commented out every occurrence of QMAKE_USE += xkbcommon_evdev, re-run qmake and make, and still observe the same build error.

ybakos

Developers have chimed in with a patch.

Nice ! Thanks for sharing

I have encountered this error during documentation-only build on Mint Linux 18.2. In fact the build error is not now actual, but the file ./qtwayland/tests/auto/compositor/compositor/compositor.pro contains the following strings:

qtConfig(xkbcommon-evdev)
    QMAKE_USE += xkbcommon_evdev

which produce the error.

I removed these strings temporarily to eliminate the error and received successful build.
