Description Semeniouk 2020-05-25 17:55:04 CEST 
After pulling latest commits from myster branch today I am not able to 
compile any Geant4 example on my macOS Catalina.
The Geant4 compiled without problem, but the compilation of examples failed with massage like I included above.

No problem on linux system.

On Mac OS the error message:

B1>make

The error is not related to Geant4, but likely to your MacOS setup (an update of Xcode?).
Try re-configuring and re-installing Geant4 from scratch.
