Wire library Visual Studio Code C++ cpp examples not working - c++

Question

I'm running example code from the Arduino Wire library (Master Sender, Slave Reciever), but I get an error in the Slave-Reciever code. It's having problems with the recieveEvent function.
The code works in Arduino, so why is it different in Visual Studio Code? Is there anything that I should change in structure or anything? I don't see why this would be.
// Wire Slave Receiver
// by Nicholas Zambetti <http://www.zambetti.com>
// Demonstrates use of the Wire library
// Receives data as an I2C/TWI slave device
// Refer to the "Wire Master Writer" example for use with this
// Created 29 March 2006
// This example code is in the public domain.
#include <Arduino.h>// <- I added this include
#include <Wire.h>
int led = LED_BUILTIN;
void recieveEvent(int howMany); // <- I added this
void setup(){
Wire.begin(9);
Wire.onReceive(recieveEvent); //<-This is the issue spot
Serial.begin(115200);
}
void loop()
{
delay(100);
}
// function that executes whenever data is received from master
// this function is registered as an event, see setup()
void receiveEvent(int howMany)
{
digitalWrite(led, HIGH); // briefly flash the LED
while(Wire.available() > 1) { // loop through all but the last
char c = Wire.read(); // receive byte as a character
Serial.print(c); // print the character
}
int x = Wire.read(); // receive byte as an integer
Serial.println(x); // print the integer
digitalWrite(led, LOW);
}
This is the Make File:
