ESPHome install to board fails with CMake error

Hi All -

I’m having issues flashing my first ESP32 using ESPHome via Home Assistant. Each time I attempt to install the auto-generated YAML, ESPHome gives me a build error. I am pretty early in the process here, so must be doing something wrong.

This is an ESP-WROOM-32 with ESPHome 2023.2.4 and HAOS 2023.2.5

These are the steps I followed, and I apologize for the fuzziness in some of the earlier steps:

  1. I went to ESPHome Bluetooth Proxy and installed the firmware there.
  2. Fairly sure after that, I was able to initially add the board via the ESPHome Add On in Home Assistant, without any errors.
  3. I attempted to add to the config, and ended up with a build error, which I’ll include at the end of this post

I tried quite a bit after this, including pointing to an older version of esp-idf as suggested in this thread. That got me a little further, but I ended up with a different build error.

I also tried stripping down the YAML to barebones, with the same result. Eventually I used the Bluetooth Proxy site to reinstall that firmware as a new starting point, and was never able to get back to what I recalled from step 2 above.

Here is the YAML I’m using

substitutions:
  name: esp32-bluetooth-proxy
  friendly_name: Bedroom BTLE
packages:
  esphome.bluetooth-proxy: github://esphome/bluetooth-proxies/esp32-generic.yaml@main
esphome:
  name: ${name}
  name_add_mac_suffix: false
  friendly_name: ${friendly_name}
api:
  encryption:
    key: <I removed this to share>
wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

And here is the error I ultimately get:

CMake Error at /data/cache/platformio/packages/tool-cmake/share/cmake-3.16/Modules/CMakeTestCCompiler.cmake:60 (message):

Any suggestions would be greatly appreciated. I can’t seem to get beyond this.

Hello, do you try using the “Clean Build Files” options under the 3 dots in the device in ESPHome Dashboard? I have to use this option for my esp-idf devices every time I compile them.

I’m running into the same issue, cleaning build files did not work.

Same here with ESPHome 2023.11.6:

EDIT:

Was able to compile with workaround to define Arduino framework (found here):

esp32:
  board: esp32dev
  framework:
    type: arduino

Going to Arduino framework fixed it for me too. However, I’ve read that this was not the advised framework for Bluetooth Proxy due to stability/latency? (Sorry, can’t find the source of that at the moment).

This might be helpful for others too using ESP32-S3: esp-idf framework problem? · Issue #4945 · esphome/issues · GitHub

This worked for me:
Resolve issue compiling esphome 2024.7.x - 2024.10.x on esp32-c6 · Issue #5938 · esphome/issues

Added this to the yaml:

esp32:
  framework:
    type: esp-idf
    version: 5.2.2
    platform_version: 6.7.0
