Re: Ubuntu 20.04 cannot find the Hackrf board?

[George Edwards]

Hi Marcus,

There are many times I am building custom dsp algorithms that the packages do not support, so I need to write the C++ or Python code for my signal processing algorithms.

The Linux distribution after I install gnuradio understands the OOT gr_modtool, how do I replicate this on the Windows PC?

Thank you!

George

No, that is not correct.

Why would you then build from source? Just install the packages.

Best regards,
