Thank you for your prompt answer but I've tried but it does not work unfortunately:
I've put in C++ code:
extern "C" {
extern struct
{
short int nstream;
short int nunit;
short int ncomp;
} general_;

extern struct {
float tau;
} pi_;
}
This structure has been suggested by the article " How to access FORTRAN COMMON blocks from C/C++ - Advanced Features and User Routines - FLUKA User Forum[^]."
But I've got the following error list:
