Set clock source not implemented in this version

Hello I am trying to synchronize two USRPs together using the MIMO
cable.

I tried to set the clock and time source to the MIMO cable and it says
that
this feature is not available in this version.

Is this true or am I missing something?

How do this?

The set_clock_source() call requires the master branch of UHD. This will
be tagged as release very shortly. The previous call was
set_clock_config(), this should still work, but GRC will not generate
calls to set_clock_config() on the version of gnuradio you have.

Can I recommend you marcus’s build script as an easy way to install uhd
and gnuradio master branches?
