unable to build using arduino-esp32 as a component in esp-idf project

[pataga]

I followed the instructions at
https://github.com/espressif/arduino-es ... 4672128146
with a fresh copy of esp-idf. Made a copy of esp-idf-template, added the components directory and cloned esp32-arduino into /components/arduino.
Changed main/main.c to main.cpp with the following code

Code: Select all

#include "Arduino.h"

extern "C" void app_main(void)
{
	initArduino();
	Serial.begin(115200);
	pinMode(4, OUTPUT);
    int level = 0;
	Serial.println("\r\ntest arduino");
    while (true) {
        digitalWrite(4, level);
        level = !level;
		delay(100);
    }
}

After running 'make menuconfig', 'make clean' and then 'make flash', I eventually get the following build error :
