You're actually generating an executable in the first step and not an
object file. (The error occurs because you're then attempting to re-link
the executable with all the standard libraries.) You probably want to
add '-c' to the first command line to compile without linking.

As a side note, you probably also want to add either '-g' to both steps
to include debugging information in the executable, or add '-O2' to the
first to build an optimised release.

Hope that helps,
Rup.
