No, because

	1) "Architecture" refers to the instruction set architecture of a  
machine, which has nothing to do with the programming language;

	2) gcc and g++ are just two front ends, the first for C and the  
second for C++, to the same back end;

        3) gcc was used because libpcap and tcpdump are written in C, not C++.

What do

        uname -mpi

and

        file `which tcpdump`

print?  You might, for example, have an x86-64 version of tcpdump and  
an x86 machine, which won't work.
