That's because you compiled instead of compile-and-link.  The former
produces an object file, the latter produces an executable program.

It means some of the library functions called by your programs wasn't
found by the linker.

I think section 8.7 explains this: you need to use gxx or gpp insteadd
of gcc to link C++ programs.

The prompt shows the current working directory.  To change to another
directory, use the CD command, like this:

	   cd c:\myprograms

If the directory C:\myprograms doesn't exist, you will need to create
it first:

	   mkdir c:\myprograms
