ChrisR:
I am unalbe to compile event he simplest default project with Lazarus to the Linux QT5 widgetset. This is new, as previously I had no problem, even with complex projects. My libqt5pas seems to be the latest. I am using Ubuntu 20.04

You must use libQt5Pas from lazarus trunk - in other words you must rebuild libQt5Pas on your own since I've added QAccessibility* in trunk.
If you don't want to build libQt5Pas then use stable Lazarus release.

Where is it best installed? Do you have any notes on doing that? I've always assumed that Lazarus + Qt was just a combination that stopped working on occasion.
I can confirm the same problem with lazarus-trunk and Debian "Bullseye" i.e. testing/not-yet-stable.

You must install qt5 dev packages (don't know exact names)
I've copied libQt5Pas.so.1.2.9 manually after compilation.

Install from where: the distro or Lazarus svn?
I'm entirely used to installing libqt*pas from the distro, but your suggestion earlier was that it also existed as part of Lazarus.
