Particle.io complier error with an empty program

[sentientthings]

Compling the following with a Particle.io argon on deviceOS 2.1.0 (or 2.0.1) with ArduinoJson 6.18.0

#include "Particle.h"
#include <Arduino.h>
#include <ArduinoJson.h>

void setup() {

}

void loop() {
  // not used in this example
}

Gives the following raw compiler error:

Hi,

We saw the error 'const void*' is not a pointer-to-object type with several boards already:

• ArduinoStringAdapter.hpp:7:10: fatal error: WString.h: No such file or directory #1381, with Teknic ClearCore
• ESP8266, pgm_read_ptr(): error: 'const void*' is not a pointer-to-object type #1442, with ESP8266
• Using ArduinoJson V6 with Industruino controller #1519, with Industruino
• error: 'pgm_read_ptr' was not declared in this scope #1536, but the user didn't tell which board it was

In each case, this comes from a bug in the Arduino Core API.
This bug was fixed by arduino/ArduinoCore-API#118 in October 2020, but wasn't immediately propagated to all derivatives.

First, make sure that every related piece of software is up-to-date.
If the problem persists, please open an issue in the relevant project and point them to arduino/ArduinoCore-API#118.

As a workaround, you can disable support for PROGMEM in ArduinoJson. See ARDUINOJSON_ENABLE_PROGMEM.

Best regards,
Benoit

Worked. Thank you.
