ESPHome 2024.4 compilation errors

[ztox]

I started seeing compilation errors with ESPHome 2024.4. I stripped back the yaml config, and followed the README advice around a clean build. This appears to possibly be an issue in framework-arduinoespressif8266 but posting here after not finding anything related in a cursory search of other issue reports in https://github.com/esphome/issues/issues.

Steps:

Stripped down config yaml to minimum (see attached)

• rm -rf ~/.platformio/
• rm -rf ./.esphome/
• esphome -v compile heatpump-1.yaml

Configuration files

https://github.com/ztox/homeassistant-config/blob/master/esphome/heatpump-1.yaml
https://github.com/ztox/homeassistant-config/blob/master/esphome/common/packages/heatpump.yaml
https://github.com/ztox/homeassistant-config/blob/master/esphome/common/packages/andover-wifi.yaml

Closing this issues, as it is not related to the mitsubishiheatpump package. Compilation error resolved when I remove the native api time config (andover-wifi.yaml).

time:
  platform: homeassistant
  id: homeassistant_time

Leaving this here for future investigation --
I don't fully understand the dependencies involved between time, climate and esphome-mitsubishiheatpump. The example below keeps the time: configuration, but removes the climate: config. It compiles successfully in 2024.4.0.

I am having the exact same issue but currently using https://github.com/echavet/MitsubishiCN105ESPHome instead of geoffdavis'
Not sure what the issues would be by removing the time component either. Not sure if it is needed at all.

To add to the confusion, if you keep the time component and add the captive portal component it all compiles fine again.

Basically it seems that if you remove the captive portal then you also need to remove the time component but this is only true if you have the climate component. Once you remove the climate component then you can remove the captive portal and/or the time component but with climate you cannot have the time component without the captive portal.

Very weird

Found another person hitting this issue with emporia vue esphome/issues#5300

So it seems xtensa time.h is clashing with esphomes time.h or real_time_clock.h. I tried adding #include "time.h" but, I get the same error. I am unsure how to resolve this as I dont use C language.

I agree with their analysis but can't figure out a solution. Also, I can't figure out why the climate platform triggers this as there are no uses of "time" in the climate platform or geoffdavis' code at all.

Just adding a note here that running without the time component, as well as without logging, captive portal, web server and ap components has not only not caused any issues for me this past week but seems to have resolved an occasional, random, crash that would knock my esp07's down and stop their communicating with the heat pump. So, for those in the future hitting this compilation problem or having crashes, try removing all those components and you may find success.
