[Debian-med-packaging] Bug#874858: [edfbrowser] Future Qt4 removal from Buster

[Teunis van Beelen]

Hi,

EDFbrowser compiles fine with both Qt 5.6.1 that comes with Opensuse Leap
42.2 as well
with the latest Qt 5.9.1 compiled from the official Qt vanilla source.

Some serious bugs are present in Qt 5, specially in the Qt 5.6.x series.
Qt 5.9.1 seems to be better but still not as good as Qt 4.8.7.

Qt5 is a "non-blocking" framework, it's released with lots of blocking P0
and P1 bugs:

20QTBUG%20AND%20priority%20in%20(%22P0%3A%20Blocker%22%2C%
20%22P1%3A%20Critical%22)%20AND%20resolution%20%3D%20Unresolved%20AND%
20affectedVersion%20in%20(releasedVersions()%2C%205.9.1)
%20ORDER%20BY%20key%20DESC

Have you seen any compile errors with EDFbrowser & Qt5 on Debian?
Let me know if there are any issues.

Kind Regards,

Teunis
