It outputs errors to stderr not stdout. stderr has file descriptor 2;
you could use shell redirects, e.g.:

    g++ -c foo.cc -o foo.o 2>errorfile

The main differences between g++ and gcc are that g++ will compile .c
files as if they were C++ and that g++ automatically includes libstdc++
when it is asked to link. You should use g++ for your link step.
