Description Andrea 2022-01-15 10:26:15 CET

I built Geant4.11.0.0 on Windows x64 in Release mode without errors.

If I build Geant4.11.0.0 on Windows x64 in Debug mode, I obtain an error from the Linker (LNK 1189) that said that “the limit of 65535 objects or members in a library has been exceeded”, in particular for the G4processes library.
And the resulting G4processes.dll has a size of 0 KB.

This is along known issue with Windows builds of the G4processes library. We're reviewing a new structure for organising libraries to reduce their size and resolve this issue. However, this is a long term project and so marking this as a LATER.
