if you are not using the script and are attempting to run vvp directly
then yes, in the strictest sense, you are "doing something wrong"
because one hell of a lot of pre-processing is required to even get
the damn verilog to be recognised by iverilog.

*use the scripts* (runsimsoc) is the message here, do not waste your time.

however you also need to bear in mind that iverilog is a simulator
not a compiler and it is at least 10x to 50x slower than verilator.

you therefore also need to keep an eye on the fst gtkwave output:
refresh gtkwave periodically and check its progress.
