Hi Alan I was able to build the plplot using qt6.1 and found out that there were other classes (the 2D transformation Matrix class) that were dropped in qt6. So I made a small patch replacing that class and some others minor changes with function members that became deprecated in qt 6.0
I've tested it in my default qt 5.15 and in the latest qt6.1.2 version. Everything looks to work very fine. So I think that when the time is right one can face without any worries the transition from qt5 to qt6 without the need to use the Core5Compat package. cheers On Thu, Jul 8, 2021 at 12:26 AM Alan W.

The patch was tested in Opensuse leap15.3 Using Qt version 5.15.2 from kde opensude official repositories. And also tested using opensuse leap15.3 Q6.1.2 from the offiocial qt account https://login.qt.io/. Please be aware this is only a patch to the c++ qt driver code the cmake was not yet changed to allow an option to select or use qt6 instead of qt5. --- bindings/qt_gui/plqt.cpp | 25 +++++++++++++------------ 1 file changed, 13 insertions(+), 12 deletions(-) diff --git a/bindings/qt_gui/plqt.cpp b/bindings/qt_gui/plqt.cpp index 2df02d756..be787b49b 100644 --- a/bindings/qt_gui/plqt.cpp +++ b/bindings/qt_gui/plqt.cpp @@ -24,6 +24,7 @@ #include "qt.h" #include<list> +#include <QTransform> // Global variables for Qt driver.
