Geant4 GUI Issues

Getting Started
1

Hey everyone,

It’s great to be apart of this community so thanks in advanced for your help.

I have been able to get Geant4 running on Linux Mint 20.1 Cinnamon that I have configured on my laptop.

My build included using the Geant4, and CLHEP source code from Github and compiling as per the instructions provided.

Essentially I have just copied and pasted what I set Geant4 up as below.

cmake -DCMAKE_INSTALL_PREFIX=~/work/geant4 -DGEANT4_USE_QT=ON -DGEANT4_USE_OPENGL_X11=ON -DGEANT4_USE_RAYTRACER_X11=ON -DGEANT4_USE_GDML=ON -DGEANT4_USE_SYSTEM_CLHEP=ON -DGEANT4_BUILD_MULTITHREADED=ON -DGEANT_USE_EXPAT=ON -DCLHEP_INCLUDE_DIR=/home/karti/work/CLHEP/include -DCLHEP_LIBRARY=/home/karti/work/CLHEP/lib/libCLHEP.so -S source/geant4/ -B install/geant4/

Now this seemed to work but everytime I build an Example such as STCyclotron i get GUI errors, and the GUI only partially loads missing the toolbar. I have tried to load up the relevant macro which doesn’t work. I think it might be to do with the version of QT I am using but I am unsure, as I am new to Linux.

I have uploaded some screenshots below, if you have any ideas please let me know.

I have updated this with the log I get when using the make command. Perhaps the issue lies with the portions highlighted with bold font?

the error message in your screenshot:

Can not open a macro file. Set macro path with "/control/macroPath" if needed.

The line above the error message:

/control/execute Macro/init_beam.mac

you seem to be missing a folder with name “Macro”, containing the file “init_beam.mac”…

EDIT: I think you are right about the init_beam.mac file but the G4Exception-Start warnings and GUI issues are occurring with all examples. I can’t seem to get the toolbar to load above.

did you find the missing file, or is it still missing for all examples? Reading further I see “Batch is interrupted” - so maybe some commands are not executed (yet) due to the missing file?

In your screenshot, I see all the icons in the toolbar for the lines that you highlighted :slight_smile:

Hey Weller,

I followed what you mentioned and figured out the GUI mac file was wrong and should have stated /control/execute Macro/init_parameters.mac as init_beam.mac didn’t exist.

Changed this and the simulation now works with the toolbar, and hasn’t presented errors. The toolbar I meant was displayed on top and allows you to easily change settings in this example, can see it here as I can’t upload more screenshots https://twiki.cern.ch/twiki/bin/view/Geant4/AdvancedExamplesSTCyclotron

I’ll try and see if the other examples have their own errors that need to be fixed.

edit: glad it works :slight_smile:

the command that was probably skipped was the line “/control/execute Macro/GUI/gui.mac”…

Yes, well hopefully I can get around to building all the examples and then using it to do my own thing.
