Missing blocks

[princeje]

I'm new to GNUradio and when I open adsb_rx.grc file, gnuradio-companion is showing "Missing blocks". Do I need to build something or get the gnuradio repo cloned and put this inside of it to build it?? I'm lost.

You need to install the gr-adsb out-of-tree module first. Follow the installation instructions in the README and then restart gnuradio-companion. Let me know if you continue to have issues.
