Description

When compiling from the Arduino IDE 2.1.0, I get the following error (but the same program compiles fine in the Arduino IDE 1.8.16). This seems to be the same error as in issue #6647, which is vague about how it was fixed, if it was at all (comments seem to say the issue is with PlatformIO, but I'm not using PlatformIO.

Other Steps to Reproduce

It works fine in Arduino 1.8.16, but gives the above error with Arduino 2.1.0

I have checked existing issues, online documentation and the Troubleshooting Guide

same here, can you please help with triage @P-R-O-C-H-Y?

[P-R-O-C-H-Y]

@VojtechBartoska I am not able to reproduce the error with Arduino IDE 2.1.0.

@Patronics Can you please send more information on how to replicate the issue? Exact example will be handy :)

Closing this issue as no more informations provided and I was unable to reproduce it.

I had the same error in Arduino IDE 1.8.19
I could solve it by updating ESP32 in the boards manager from 2.0.4 to 2.0.11
