Reviving Geant4 and QT53d driver

Getting Started

Hi All, I recently installed Qt5 Installer from the qt.io website, in order to enable
cmake -DGEANT4_USE_QT=ON
for interactive visualization while running example B1. While the above command was carried out, the system still disabled the Qt3d capability due to the same error it registered with other users too:

I decided to check it out and found all the three “missing” libraries in /usr/lib64/qt5/qml folder. Has anyone had any success in resolving the Qt3d capability issue while executing the above command? Thanks

Hi Neera

As I recall when I did this myself, you have to ask the Qt installer at some point in the installation process to install those packages.

However, I wouldn’t worry about Qt3D - it’s still somewhat limited, under development. I recommend ToolsSG (TSG).

You don’t say what platform, nor the Geant4 version. We are currently focused on Qt6.

The CMake warnings are a little concerning, but if there does not seem to be any trouble, ignore them. (Search for “expat” in the Geant4 Forum to find out more.)
