adder.vhd is the VHDL definition of your circuit. You need to simulaate that with ghdl, and pass the output from ghdl into gtkwave. Its been a long time since I played wtih ghdl, but vaguely recall that you have to call it a number of different times with different options. You end up with a compled test-bench for your circuit, which you can execute and get VCD output suitable for feeding gtkwave. Hope this helps, even if I don't know ghdl enough to be of further specific assistance.
