Hi,

No, you don't need to rebuild all of Qt. Just clone the QtWayland module and build it with your 5.8 Qt. Don't forget to call make install afterward.

Interesting. I cloned QtWayland from here (https://github.com/qt/qtwayland),
and made sure I have all the dependencies installed for Ubuntu (described here https://wiki.qt.io/QtWayland)

Next I opened qtwayland.pro with QtCreator and attempted to build it, but it now fails with a bunch of errors:

Am I doing wrong or do I lack some dependencies still?

[SGaist]

Do you have the development package of ICU installed ?

[SQEW]

@SGaist

Yes

libicu-dev is already the newest version (57.1-4).
libicu-dev set to manually installed.

[SGaist]

It looks like it's searching for the 56 version.

I'm not sure whether the official package comes with a bundled version but I think so. Can you check that ?
