Errors go to stderr, the '>' operator only redirects stdout. If you are
using sh/ksh/bash/... then you need 

   g++ hello.cpp >bug 2>&1

Basically, this tells the shell to redirect output to file descriptor 2
(stderr) to the same place that the output from file descriptor 1 (stdout)
is going to, which in this case is the file named "bug".

If you are using csh/tcsh/... then you need

   g++ hello.cpp >& bug

This tells the shell to redirect both stdout and stderr to the same file, "bug".
