You should be sleeping.

Oops, yes.

Yes. I built subsurface from source.

The PPA only has version 4.7.2. It is the problem of working with a long 
term support version (16.04 in this case). Towards the end of the 2-year 
period, most of the supporting libraries are outdated.

The base version is Qt 5.5, coming from the PPA. But at one stage I did 
install 5.7

~$ qmake -v
QMake version 3.0
Using Qt version 5.5.1 in /usr/lib/x86_64-linux-gnu

If I do:

~$ dpkg -S libQt5QuickWidgets.so.5

I get:

libqt5quickwidgets5:amd64: /usr/lib/x86_64-linux-gnu/libQt5QuickWidgets.so.5
qt57declarative: /opt/qt57/lib/libQt5QuickWidgets.so.5.7
qt57declarative: /opt/qt57/lib/libQt5QuickWidgets.so.5
qt57declarative: /opt/qt57/lib/libQt5QuickWidgets.so.5.7.1

Does this make any sense?

Kind regards,
