problem to make the project

[guanucoluis]

Hello,
I cloned the project but I had problem when i ran make run...

(base) lguanuco@latitude:github$ git clone https://github.com/verilator/example-systemverilog.git
(base) lguanuco@latitude:github$ cd example-systemverilog/
(base) lguanuco@latitude:example-systemverilog$ make run

-- Verilator coverage example

-- VERILATE ----------------
verilator -cc --exe -Os -x-assign 0 -Wall --assert --coverage --build -j -f input.vc top.v sim_main.cpp
%Error: Invalid Option: --build
%Error: Command Failed /usr/bin/verilator_bin -cc --exe -Os -x-assign 0 -Wall --assert --coverage --build -j -f input.vc top.v sim_main.cpp
Makefile:79: fallo en las instrucciones para el objetivo 'run'
make: *** [run] Error 10

(base) lguanuco@latitude:example-systemverilog$ verilator --version
Verilator 3.900 2017-01-15 rev verilator_3_890-15-ge6d7e7e

I tried run the script without --build -j flags but I'm still having problems...

(base) lguanuco@latitude:example-systemverilog$ make run

I didn't find more information about this example. I want to apply the verilator coverage feature to my systemverilog project.
Regards,
Luis.

It looks like you are using an old version of verilator, please use at least 4.038, ideally the current stable release 4.100.

Closing as think this will solve it, but feel free to post more here.
