Compile issue when using version 1.42 with EasyButton library

[jomoengineer]

I am going though a ESP32 course with Tech Explorations and part of their code is using the EasyButton library version 2.0.3 which has a dependency of MegunoLink. However, when using version 1.42 of MegunoLink, the code fails to compile. With version 1.41 of MegunoLink, the code compiles and runs without issue.

The error is seen below:

Hi, yes I think this is a bug introduced by updates to the espressif libraries. I think we put a fix for this in our library repository. Please download from here and overwrite the older files. https://github.com/Megunolink/MLP/tree/develop Need to use the develop branch files. Cheers Phil

@Megunolink

Yep, that seems to clear up the issue. It builds without issue with the code from the link.

Thanks for posting this.

@Megunolink When will the fix make it into an updated release accessible from the Library manager in the Arduino IDE?

[Megunolink]

Good question. Will look to do it in the next few days. Phil

Yes, I was able to install 1.43 and the compile errors that I was seeing with the EasyButton Library are not there now.
