Error "cstddef: No such file or directory" on use AzureIoTHub Good Morning
I'm trying to integrate with Azure IoT with Arduino Mega 2560.
I imported the AzureIoTHub and AzureIoTUtility lib.
I just created this part of the code
 #include &lt;AzureIoTHub.h&gt;

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

however, when I compile, I get the following error message.

In file included from
C:\Users\MercurioNote\Documents\Arduino\libraries\AzureIoTUtility\src/azure_c_shared_utility/platform.h:7:0,

fatal error: cstddef: No such file or directory  #include 

I imported ArduinoStl and the problem continued.
what am i doing wrong in this case?
thanks
Azure IoT is only supported on ESP8266 and ESP32. As stated in the README for the library:

Currently supported hardware:

ESP8266 based boards with esp8266/arduino

SparkFun Thing

Adafruit Feather Huzzah



ESP32 based boards with espressif/arduino-esp32
