Radioactive decay running error

Hello Dear geant4 user !
Please I tried to run the rdecay01 in extended example but got this error (upload).
Someone help me to solve it.


Did you create the build directory separately from the rdecay01 example source?

I copied the rdcay01 source example form the geant4 Path directory to another place before compile and run.

Hi ! I finally solved the problem. I just had to change the name of the target, it had the same name as the rdecay source file.
Thank you.
