Warning at compilation and no frequency found

Hi all

I tried this repo but I have a warning during compilation :

When I run the frequency test no frequency is found. How do I know if the CC1101 is correctly plugged ? I bought this one : https://www.amazon.fr/dp/B0CPY5LWFY?psc=1&ref=ppx_yo2ov_dt_b_product_details

Here are some logs :
