Dear @bmorgan ,
Thank you for the heads up.
I reinstalled Geant4 with X11 turned off and based only on Qt5.
This is the cmake command:
cmake -DCMAKE_INSTALL_PREFIX=/Users/arkasantra/Geant4_Install -DGEANT4_INSTALL_DATA=ON -DGEANT4_BUILD_MULTITHREADED=ON -DGEANT4_USE_OPENGL_X11=OFF -DGEANT4_USE_PYTHON=ON -DGEANT4_USE_QT=ON -DGEANT4_INSTALL_EXAMPLES=ON -DGEANT4_USE_SYSTEM_ZLIB=ON -DGEANT4_BUILD_TLS_MODEL=global-dynamic -DGEANT4_USE_GDML=ON -DCMAKE_PREFIX_PATH=$(brew --prefix qt@5) -DCMAKE_CXX_STANDARD=20 /Users/arkasantra/geant4-v11.2.1
The subsequent compilation and installation went fine.
I wanted to check the examples/basic/B1, so I followed this:
cd $Geant4_Installation/examples/basic/B1
mkdir build && cd build
cmake -DCMAKE_CXX_STANDARD=20 ../
make -j8
But this time I see the compilation is NOT successful:
[ 12%] Building CXX object CMakeFiles/exampleB1.dir/exampleB1.cc.o

Seems again the Qt5 is the problem.
I installed Qt5 using brew.
My system has Qt6 installed as well, but I made sure that in the PATH variable, Qt5 comes before the Qt6:
PATH=/usr/local/opt/openjdk/bin:/usr/local/opt/jpeg/bin:/usr/local/opt/krb5/sbin:/usr/local/opt/krb5/bin:/usr/local/opt/qt@5/bin:/usr/local/opt/qt/bin:/opt/anaconda3/bin:/opt/anaconda3/condabin:/usr/local/opt/gnu-getopt/bin
May I know how I should solve this problem?
I am using CMAKE_CXX_STANDARD=20 , will this be a problem?
Thank you once again,
Arka
