Hello, i am trying to run my first example (example B1) and i have encountered with an error. First of all i tried several times and checked other topics on issues on running examples. I didn’t copy the example first and i tried running it in its original directory. In my final try, i first copied B1 folder to desktop (deleted several files from the B1 folder
Thanks for the reply, i have already installed the geant4, should i delete and re-install it again ? I didn’t use -DGEANT4_USE_QT=ON while i was installing. I only followed the guide which you have linked. Also i couldn’t find what OGL is.
