Title:
the header xcb/xinput.h is missing
Status in libxcb package in Ubuntu:
Fix Released
Status in libxcb source package in Bionic:
Fix Committed
Bug description:
[Impact]
Allow Qt 5.12 to be compiled with full input support. This allows
applications to be built using complex input devices such as drawing pads.
This is used in e.g Krita which KDE builds into a Snap package for
distribution. Currently Krita does not work with pen input devices with
pressure sensitivity.
[Test Case]
Install Krita with Qt 5.12 from current Snap and note how pressure
sensitivity does not work.
[Regression Potential]
None that I can see, it's just packaging a few new header files.
----
I suspect this means there should be another package, libxcb-xinput-dev
perhaps?
I already did sudo apt install "libxcb*dev" to get all related dev
packages, but none of them provide xcb/xinput.h.
The result is that when building Qt from source, it's necessary to use
a copy of this file which Qt provides
(qtbase/src/3rdparty/xcb/include/xcb/xinput.h), because it's missing
from the system. So if you don't give the option -qt-xcb to
configure, then Qt will be built without multi-touch support.
