projbuild_gitconfig.py fails due to the empty _CMAKE_TOOLCHAIN_PREFIX argument

[ImerHamidovic]

I have noticed that the building(flashing, monitoring) of the system sometimes fails due to the empty TOOLCHAIN_PREFIX argument.

Logs:

Traceback (most recent call last):
  File "<path_to_the_script>/get_projbuild_gitconfig.py", line 25, in <module>
    TOOLCHAIN_PREFIX=sys.argv[6]
IndexError: list index out of range

It is hard to tell when and how this happens, but sometimes it just fails with the same error. I have noticed that the issue won't appear once fullclean is performed before the build.

Looking at the build.ninja file I have seen that the argument TOOLCHAIN_PREFIX does not exist once the build fails.

I have tried to build the system using the idf.py directly as well as using the VS Code extension shortcuts. Both of them are sometimes failing.

ESP-IDF version: 4.4.3 Operating system: I have used both Linux Ubuntu and Windows 10(same behavior) Target: esp32 ESP Insights version: 1.0.1

Thank you in advance, Imer Hamidovic

It is my first time reporting some issue so I am not aware of how to properly do it. Please let me know if you need some more information.

Hi @ImerHamidovic,

When exactly do you encounter this issue? If toolchains are set properly (with . ./export.sh) and you can build the app, you should not get such error.

Did you update the asp-insights recently? If yes, you will need a clean build for this.

Hi @vikramdattu,

Thanks for the fast response.

I am using idf component manager for Insights(from _managedcomponents folder). That means I have to date Insights component.

The issue is encountered at some point after a successful build. I can not tell when exactly but, when I try to flash it or build again(not from scratch), sometimes it fails.

In order to resolve the issue I have noticed that I have to do the fullclean, before calling any other idf.py option(monitor, build, flash...)
