@RuslanSpartak Could you please clarify this part of the issue report:

Steps to reproduce.
Just try to build project

Which project do you get this error with? Can the error be reproduced using one of the example projects in ESP-IDF? If the error can only be reproduced with a custom project, please attach enough information to allow us to reproduce the issue.
For example, you may attach the relevant part of ota.cpp.

Also this part:

Custom board with esp32

Is that really the case? The logs mention RISC-V toolchain, which is not supposed to be used for the ESP32.

@RuslanSpartak would you mind trying the following patch?
0001-cxx-made-pthread-a-public-dependency-of-cxx.zip

We have an issue that looks like it's related and we're working on fixing it.

@RuslanSpartak The comments from @igrr are still valid, actually. When investigating issue reports, more specific information is very helpful for us to re-create the issue on our side. It's coincidence that we discovered the same (or similar looking) error in a different context just today and could come back quickly here.

Could you tell me how I need to use that file?

Unzip it. Then use git apply 0001-cxx-made-pthread-a-public-dependency-of-cxx.patch (on the command line) inside the IDF repository to add the patch to IDF. Unfortunately, I'm not very familiar how to do that on Windows.

Alternatively, you can go to https://github.com/espressif/esp-idf/blob/master/components/cxx/CMakeLists.txt#L4 (in your IDF repository) and change the line to: REQUIRES pthread).

REQUIRES

Thanks. I know how to do it. It worked.
Thanks a lot.

Fix from 0xjakob is working.
