[Ovmsdev] ESP-IDF v4 / v5 - baby steps

Mon Feb 6 03:37:05 HKT 2023

"idf" dependency, as expressed in (new file) `main/idf_component.yml`, 
is just ESP-IDF - this just checks that ESP-IDF is at minimum at version 5.0

This new file expresses the dependencies with new components (like a 
`requirements.txt` in Python, `Gemfile` in Ruby, `package.json` in JS, 
etc...), and they started to remove components from ESP-IDF and make 
them available as external components.
`mdns` is such a component : 
https://components.espressif.com/components/espressif/mdns

So I'm not 100% convinced it's related - but in any case you could 
remove this file completely and see if it changes something (you 
wouldn't be able to compile `mdns`-related components, but still make 
some progress)

Could you share the 3 log files please ?
