When I want to run some RFNOC blocks in Gnuradio I was faced with

My environment is Gnuradio 3.8.10

Also if you're using an RFNOC 3 approach, you should read this:
https://kb.ettus.com/RFNoC_4_Migration_Guide
https://kb.ettus.com/Getting_Started_with_RFNoC_in_UHD_4.0
And there's also the Gnu Radio workshop series, starting here:
