Please, do not top post!  Please, use proper Engligh.  Many
people subscribed to this list are not native English speakers.
Words like 'coz' can be problematic.

Then you need to make a library with the proper tools.  Because
you failed to identify the operating system, I'll assume Linux
in the following.

gfortran -c datarmodel.f
ar -cru mylib.a datarmodel.o
ranlib mylib.a

g++ your_c++_file.cpp -L/path/to/where/you/put/libraries -lmylib

PS: The fortran@gcc.gnu.org mailing list is for the discussion of 
development of gfortran.  It is not meant for general questions
concerned with how to use gfortran.
