Compiling Geant4 with Qt5

Recording, Visualizing and Persisting Data
#1

Hi,

I’m trying to compile Geant4 (4.10.06.p1) with the Qt5 flag enabled on a Mac (Catalina 10.15.3). With brew, I’ve installed the latest Qt package (5.14.1). It fails as it is looking for a Qt3.xx or Qt4.xx. I cannot revert back to Qt4.xx (it doesn’t work on my OS). Is there any way to still make this work?

Cheers,
Johan

Hi Johan

You have to point to your Qt5 installation. For example

-DGEANT4_USE_QT=ON
-DQT_QMAKE_EXECUTABLE=~/Qt/Qt5.14.1/5.14.1/clang_64/bin/qmake
-DCMAKE_PREFIX_PATH="~/Qt/Qt5.14.1/5.14.1/clang_64 \

See Installation Guide.
