Can not find the make -j option that failed while installing package.

[StevenLi-phoenix]

As am following the installation guide and found an error that I can not locate and fix.

As I am running:

python setup.py install

and the message:
-- Build files have been written to: /content/pymembrane/pymembrane/cppmodule/build
make: the '-j' option requires a positive integer argument

But where is this make -j located? I search all the code related to make and -j. Nothing found.

Full log:

Dear Steven Li
Thank you for pointing this out, I guess that you are trying to run it in a single processor (thread) machine. I knew that it might be an issue but I figure that none would compile it like so. Nevertheless, I have now adjusted the setup.py to count for such oddities, please let me know if it resolves the issue.

[StevenLi-phoenix]

It solved my issue. Thanks a lot
