You're linking _two_ files, the result of compileing main.cpp and the
result of compiling person.cpp.

g++ -c main.cpp                        <==== this creates main.o
g++ -c person.cpp                      <==== this creates person.o
g++ -o <programname> main.o person.o   <==== this uses g++ to link them 
       ===========
       put whatever you want the program name to be in place of
<programname> above.
