_Geant4 Version: 11.2.1
_Operating System: Windows 10
_Compiler/Version: Visual Studio 17.11
_CMake Version:3.30.2

Hello
I am trying to run a previously generated .exe file, but the error below appears. I have reinstalled Geant4 on another device. The code is running well, and B1’s simple example works fine. Do you have any idea how to solve this error?

Thanks in advance.

BabySteps_3.exe - Entry Point Not Found
The procedure entry point ??0G4VUserDetectorConstruction@@QEAA@XZ could not be located in the dynamic link library
C:\Users\morad.hamad\Geant4\geant4-v11.2.1\share\Geant4\examples\Research\Project\StepsByStepConstruction\5-CollimatorsAndDetector\build\Release\BabySteps_3.exe.

Difficult to say, but if you generated this executable on a different machine and different version of Geant4, that can lead to various incompatibility issues. As B1 is working, have you tried recompiling this other application on the new machine?

Thank you for your response. Yes, I have tried recompiling the code but I get the following error:

Focussing on this line and error message, there’s not a huge amount to go on online regarding that error message so I can only give a couple of pointers/suggestions:

  • If this wasn’t already a fresh, from scratch build, try deleting the build directory (for this application) and starting a fresh one. This is to confirm that there’s no caching/copying issues.
  • Based on this same issue in a post on the CMake Discourse, it might be that the path is too long (though my count is below the 260 character limit mentioned).
    • Try moving the folder with your codes C:\Users\morad.hamad\Geant4\geant4-v11.2.1\11.2.1\share\Geant4\examples\Research Project to, say C:\Users\morad.hamad\Geant4\Research Project to shorten the path and see if that helps.
    • This is any case better practice so you don’t mix up your code with that of the toolkit.

Awesome!
Thank you very much for your help. I moved the code to another shorter path per your guidance, and it works perfectly!

Have a nice day!
