Can't compile projects for esp32c6 target

Hello.
Im compilling my projects for ESP32 for a long time via windows console.
Im using Notepad++ for writing code and windows console for building and flashing ESP32.
Everything is perfect. All projects are compiled as well with standard chain:
Code: [Select all] [Expand/Collapse]
  1. idf.py build
  2. idf.py flash or idf.py app-flash

Today I tried to compile my project for ESP32-C6-WROOM.
I tried to set target by
Code: [Select all] [Expand/Collapse]
  1. idf.py set-target esp32c6

but the error appeared:

Also I tried to set other variants: esp32, esp32c2, esp32c3, esp32s2, esp32h2 and projects compiled ok.

I'm using IDF versions 5.2.2 and 5.2.1 and the results the same.
IDF 5.2.2 was downloaded today from official site and installed as I have done it before with previous versions.

Could you help me what is the problem and how to fix it?

Hi Ildar Belkin,

we are sorry for this issue. The error message is not clear and provide not enough information to pinpoint the issue. We already track this problem and will address it soon.

In the meantime, we can try to find the root cause manually. Is this some project publicly available we can try to build? If not then can you share please the list of components used in your project?

Hello ESP_Roland!
No problem :) . Thank you for reply. I've sent you my project by private message.
If I can help you I will do you need to check or else for fixing.

I don't see you being use any external components. However, in your Kconfig.projbuild you have several "default" and "range" statements applying to certain IDF_TARGETs. You have these for those chips which are working for you. But you don't have them for ESP32-C6.

If you have an integer-based Kconfig option but none of the "defaults" statements are enabled then it will assume that it is an empty string "". And it cannot make an integer out of empty string. This is what the error message is about.

Hello ESP_Roland.
Thank you! You are right!
I've added IDF_TARGET_ESP32C6 to Kconfig.projbuild and it fixed my problem.
Everything is working as expected now.
:)

Hi.
I'm dealing with a different target (ESP32) but I can refer to this post for the following message which I'd like to diagnose:
**********
-- git rev-parse returned 'fatal: not a git repository (or any of the parent directories): .git'
-- Could not use 'git describe' to determine PROJECT_VER.
***************
It does not seem a blocking issue, but I'd like to investigate and, possibly, get rid of.
Is it possible?

Additionally, again low severity, I got this warning as the first line of the ESP-IDF 5.2 CMD window
******
Setting PYTHONNOUSERSITE, was not set
******
Could it avoided? How to?

Thank you in advance.
