[Gate-users] R: Centos 8 compilation issues

Thu Jan 28 08:59:34 CET 2021

Hello,

I successfully installed Gate9 at Centos8.
What you need is to compile both root and Geant4 using c++17 flag (you 
can do this throw the ccmake  in the advance mode). My configuration is 
the following

gate9

geant4.10.06
cflags: -DG4INTY_USE_XT -DG4VIS_USE_OPENGL -DG4UI_USE_TCSH 
-DG4INTY_USE_QT -DG4UI_USE_QT -DG4VIS_USE_OPENGLQT -I/usr/include/qt5/ 
-I/usr/include/qt5/QtCore -I/usr/lib64/qt5//mkspecs/linux-g++ 
-I/usr/include/qt5/QtGui -I/usr/include/qt5/QtWidgets 
-I/usr/include/qt5/QtOpenGL -I/usr/include/qt5/QtPrintSupport 
-DG4VIS_USE_OPENGLX -W -Wall -pedantic -Wno-non-virtual-dtor 
-Wno-long-long -Wwrite-strings -Wpointer-arith -Woverloaded-virtual 
-Wno-variadic-macros -Wshadow -pipe*-std=c++1z*

root-6.22.06
cflags: -pthread *-std=c++1z* -m64

Hope this will help.
