Good afternoon. I am trying to install geant4 (version 10.7.4) via cmake. But the following error pops up:
CMake Error at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

Hi @Friedrih ,
libexpat1-dev is missing in your machine.

here are the prerequisites,
install them first

sudo apt-get install build-essential libexpat1-dev libxmu-dev cmake cmake-curses-gui qt5-default -y

and then follow the steps you were following.

After running “make - jN” (N = 4), the following red text appeared:

INSTALLATION GEANT4

After Downloading G4 any version (source), follow steps;

1. make build directory --> mkdir build; cd build
2. cmake -DCMAKE_INSTALL_PREFIX=~/path_installation_folder/ -DGEANT4_INSTALL_DATA=ON -DGEANT4_USE_OPENGL_X11=ON -DGEANT4_USE_QT=ON ../yoursourceG4    
[your source G4 -> e.g., geant4-v11.1.2 ]
[path_installation_folder --> e.g.,  /home/Geant4]

Extra DCMAKE OPTIONS ==> -DGEANT4_BUILD_MULTITHREADED=OFF -DGEANT4_USE_GDML=ON   ---> for G4GDML [GARFIELD]   [ pre-requisite -> sudo apt-get install libxerces-c-dev  ]

For G4TENDL data add -DGEANT4_INSTALL_DATASETS_TENDL=ON

3. make -jN   [where N ==> cores say 4]

4. make install

5. copy path of installation in .bashrc, i.e.
source ~/Geant/geant4-install/bin/geant4.sh

6. Set environment  -> printenv | grep G4

You are set to run your first project.

Regards,

Vijay

This is probably a network issue between this machine and CERN, possibly just a timeout/slow connection. You can try rebuilding to retry the downloads, maybe try plain make to avoid parallel downloads.

If this persists, set GEANT4_INSTALL_DATA to OFF and either:

  • Install Geant4, then run geant4-config --install-datasets (this program is in the bin folder where G4 was installed)
  • Download/unpack the datasets manually from here: Download Geant4-10.7.4 - Geant4

Thanks. What means point 6? I want to execute exampleB1.

Hi @Friedrih

Step 6 prints environment with names G4. grep is utility command that search text patterns.
To run your first project you can create build folder in example B1 and from there call

  1. cmake …/
  2. make
  3. ./exampleB1
