your error comes from this: No package 'json-c' found
install libjson-c-dev package and try again

Thank you for the solution! In the end, I solved the issue by removing “-p” from the build command!

@hbossi Could you please elaborate on -p ? what build command use -p? I’m interested to know, to have this knowledge for other cases…
