CMake error could not find esp_matter_device.cmake (CON-610)

[Okywan]

Hello,

By using the CMakeLists.txt you're using on the examples code doesn't compile:

CMake Error at CMakeLists.txt:37 (include): include could not find requested file:

$ENV{IDF_PATH}/tools/esp-matter/device_hal/device/esp_matter_device.cmake

contents of CMakeLists.txt:

For more information about build system see

https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html

The following five lines of boilerplate have to be in your project's

CMakeLists in this exact order for cmake to work correctly

This should be done before using the IDF_TARGET variable.

By using the CMakeLists.txt you're using on the examples code doesn't compile:

@Okywan Which example are you trying to build? Please provide details about branch/commit id and the set of steps you followed

[Okywan]

@dhrishi, I'm trying to compile my own code, not an example. I downloaded and installed the esp-matter repo into my tools folder. This is the commit id:

esp-matter % git log -n 1 commit 7be04110831b25ad803655b16f0a04f371438d55 (HEAD -> main, origin/main, origin/HEAD) Merge: f31db37 1b3cf7e Author: Shu Chen chenshu@espressif.com Date: Thu Jun 22 20:20:04 2023 +0800

Merge branch 'bugfix/blemesh_bridge_DAC_compile' into 'main'

blemesh_bridge: compile failed when enable secure cert DAC provider

See merge request app-frameworks/esp-matter!388

This line in the CMakeLists crashes the compiler because there is no such file: include($ENV{ESP_MATTER_DEVICE_PATH}/esp_matter_device.cmake)

[dhrishi]

@Okywan Do you have anything similar to this in your example top level CMakeLists.txt? This sets the ESP_MATTER_DEVICE_PATH and then the corresponding file (say for ESP32) is chosen from here: https://github.com/espressif/esp-matter/blob/main/device_hal/device/esp32_devkit_c/esp_matter_device.cmake

[Okywan]

@dhrishi Yes, it's there. I'm attaching the file. Problem seems to be it's not choosing device_hal/device/esp32_devkit_c/ but /device_hal/device/

Also, now it complains with the first check for ESP_MATTER_PATH, but it is defined:

esp-idf % echo $ESP_MATTER_PATH
~/proyectos/esp32/esp-idf/tools/esp-matter

@Okywan You may have forgot to source the esp-matter/export.sh. Can you please run the cd esp-matter && source export.sh

[Okywan]

No... it was sourced... printenv shows the esp matter path.

[shubhamdp]

Is esp-matter clonned inside the esp-idf/tools repository? If yes, could be a problem. Can you move esp-matter outside esp-idf repository?

[Okywan]

Yes, it is there but if that can cause issues why does VSCode extension install esp-matter command install it there?!

[shubhamdp]

why does VSCode extension install esp-matter command install it there?

VSCode Extension does not install esp-matter there. It asks user where to download it, please check the 4th point from the extension documentation. https://github.com/espressif/vscode-esp-idf-extension#about-commands

I have seem the similar issue earlier, no idea why. One reason could be, esp-idf/tools contains the build system bits. I'd suggest you move that out of esp-idf and give a try.

Closing this as it is addressed
