Hello Paul, Thank for looking into my issue. Yes, Am cross compiling for the target. Below is my configuration logs. I am implementing the client resolver application with the library. So if I cannot run the binary in my host machine, how can I generate the trust-anchor key and pass to the application. May be I can execute unbound-anchor on the target and generate the key, and then put back to the application on the host machine?
