Sperate header & cpp files for custom components

[dtila]

The problem

The build is ok but the linker give me the error:

/config/plantwatering.yaml:12: undefined reference toPlantDiscovery::PlantDiscovery()'`

All the documentation for a custom component is the code is in the header file. Can you have code in header and cpp file, when you build a custom component for esphome?

In case, how you specify the cpp files to be linked?

Which version of ESPHome has the issue?

docker version - latest

What type of installation are you using?

Docker

Which version of Home Assistant has the issue?

What platform are you using?

Hi @dtila , I am having the same issue, would you be able to point me to the part of the documentation describing how to fix this? Thanks

You have to include the .cpp file as well. But if you have any further questions, ask on the discord server or one of the forums.
