ESP32IOBoard Example Compile Error

[whoarreyou]

Hi

I tried to compile the ESP32IOBoard example from the Arduino V2.0.0 library but I am getting the errors shown below.
Sorry if I am just doing something wrong.

Add this line:

#include <pthread.h>

After this line and it should fix it.

We'll get a fix synced in for this.

Yes, great, that has fixed the first error. I still have the below error in Esp32HardwareTwai.cpp

You are running with Arduino-3.0.x which is not currently supported by the OpenMRNLite code, there should be an updated version in the near future to support 3.0.x versions.

For now I'd suggest downgrade to Arduino-esp32 2.0.17 (latest in the 2.0.x line). Keep the update for pthread.h and you shouldn't face any issues.

I did as you suggested and downgraded. It now compiles and works great. Thanks for your help.
