With [Qt 5.15 LTS](https://en.wikipedia.org/wiki/Qt_version_history) being out since May, it’s probably time to update the QT versions required by ParaView as follows:
- minimum Qt version: 5.12 LTS
- recommended Qt version: 5.15 LTS
- binaries to be built with Qt version 5.15 LTS
Any objections/concerns? If not, we should plan to do this in time for upcoming 5.9 release.

What Qt version do the various distros package by default?

It feels like rendering is faster with Qt 5.15. Did not measured that though.

Unless we get a champion to chaperon this change, this may not happen for 5.9.

ParaView 5.7 builds and works fine using Qt 5.15.1 with a number of deprecation warnings on macOS

Update: ParaView 5.9 will require Qt 5.12. Please see [https://gitlab.kitware.com/paraview/paraview/-/merge\_requests/4422/diffs?commit\_id=24fcce7e8027f48f22dee2396eb828491934838c](https://gitlab.kitware.com/paraview/paraview/-/merge_requests/4422/diffs?commit_id=24fcce7e8027f48f22dee2396eb828491934838c).

And I noticed that visual studio versions required by paraview has changed to 2017(all previous versions of paraview requires VS-2015). Looks like a big update.

Yes, there is some concern. The latest git clone from 5.9.0 Paraview does not compile with Qt 5.12. At 92%
[92%] Building CXX object VTK/GUISupport/Qt/CMakeFiles/GUISupportQt.dir/GUISupportQt\_autogen/mocs\_compilation.cpp.o
In file included from /path/to/ParaView/5.9.0/buildHere/VTK/GUISupport/Qt/GUISupportQt\_autogen/mocs\_compilation.cpp:2:0:

QT\_INIT\_METAOBJECT const QMetaObject QFilterTreeProxyModel::staticMetaObject = { {
There are about 18 such instances of an unrecognized QT\_INIT\_METAOBJECT in that source file.
This is done in CentOS7 with GCC 7.2.0.
I am testing now if it does compile with 5.15…
Edit: Same issue with 5.15…
Cheers

For me it’s ok for ParaView 5.9 & Qt 5.15.x on macOS

Eventually I got Paraview to work.
It turned out that I compiled Qt incorrectly.
Once I recompiled Qt, I could compile Paraview as well.
