I posted this topic a few days ago but still haven't found a solution yet.  However, I believe I'm able to provide more information now.  Here is a log showing what I'm up against:

vitoc# pwd
vitoc# ls
vitoc# cat test.cpp
#include <iostream>
using namespace std;

int main()
cout << "Hello world!";
return 0;
vitoc# g++ -g -o test test.cpp
vitoc# ls
test            test.cpp
vitoc# gdb test

This is on FreeBSD 5.4 obtained from a freebsd.org mirror.  Any ideas?  Thanks!
