About build GNU Radio

Hi:

I try to test the ./benchmark_tx.py -f 900M and ./benchmark_rx.py -f
900M

I got Warning, What can I do?

The warning, do it affect the usrp operation?

Thank in advance.

This means that you don’t have permissions to set rt- priority. Try
starting the application as root,
or you might add yourself to the list of users that are allowed to do
so. I can’t remember exactly how
to do that, but a quick search trough the archive should give you
information about that, since it has been
discussed before

But I also can’t understand What’s mean.

Can you detail it more.

Thank in advance.
