I would suspect a bug in the static vs shared usage of g4expat - because we provide the option of using this from the system or as provided by Geant4, handling the static and shared cases is not straightforward.

However, just to be sure, can you provide more detail on where you are seeing the linker errors (and the content of said errors) please? These are presumably in the build of Geant4 itself rather than an application?

Depending of your exact use case, you may also be able to provide a standalone build using dlls via CMake's BundleUtilities.cmake script (try cmake --help-module BundleUtilities). It's not particularly well documented, but I know it's possible to use this to provide a .app style bundle on Mac and Linux. We'll of course try and fix the static build as well!

Cheers,

Ben.
