ESP32S3 - how to compile?

I try to compile the project with Arduino IDE (2.1.1 - Win64) - but no success.
The right processor was selected, the HELTEC JSON for the ESP32S3 stick loaded.

I get :
Compilation error: declaration of template parameter 'T' shadows template parameter


(same for other processor types …)

Any idea? Somebody have solved this?

THANKS!

Same issue here. Let me know if you manage compile it.

Use platformio

:grinning: - Question was - how to compile it with Arduino as suggested here:
https://github.com/1technophile/OpenMQTTGateway :

… or build your own configuration with PlatformIO or Arduino IDE

There seems something not compatible with Arduino IDE.
With PIO it is working, agree…
