Just a general update on this:
* Qt 5 requires PySide2, which is only just beginning to be distributed. This seems to be the main issue at this stage.
* Building with Qt 4 and Python 3 is tricky, because some of the PySide (not PySide2) tools/libraries want to pull in Python 2 libraries. The packaging dependencies are such that you can't install everything we need from PySide only for Python 3...
* Ubuntu 18.04 is distributed with Qt5.9.5, but most of the PySide2 packaging at this stage is for Qt5.11
kkremitzki - I've got "deb http://ppa.launchpad.net/freecad-mainta ... ily/ubuntu
bionic main" added to my apt sources, which seems to be bringing in the Debian PySide2 (https://tracker.debian.org/pkg/pyside2
) - is that correct? On my Ubuntu 18.04 machine, trying to install libpyside2-py3-5.11 leads to an unmet dependency on "Upstream-Version". I'm also wondering how this package will expect Qt5.11 to be installed - mine's in /opt/qt511 - should I be installing Qt5.11 from Qt directly?.
