Compile error on Particle Photon Firmware 0.6.2

Created by: kasperkamperman

@I'm trying to use ArduinoJSON on the Particle Photon. I use the latest stable firmware 0.6.2.

I've included the the .h file like #include "ArduinoJson-v5.11.0.h" and it's stored in the application folder (I compile offline with po-util).

The .hpp gave the same errors.

Minimal example:

#include "Particle.h"
#include "ArduinoJson-v5.11.0.h"

void setup() {

}

void loop() {
  
}

Error:
