Error compiling code - vtable undefined

[Pyro-E]

Hi, getting error with "undefined reference to vtable" during compiling. Please help?

HW - esp32c6

Please try with the latest version is 3.1.0

[sivar2311]

Please name the Espressif32 Arduino Core Version, the board and the sketch you're trying to compile.

[sivar2311]

I have no issues compiling the switch example for ESP32C6 Dev Module

• Espressif Arduino Core version 3.0.2
• ArduinoJson version 7.0.4
• WebSockets version 2.4.1

[Pyro-E]

Still same error.

My code (power measure):

//board - https://wiki.seeedstudio.com/xiao_esp32c6_zigbee/
//Espressif Arduino Core version 3.0.2
//ArduinoJson version 7.1.0
//WebSockets version 2.4.1

bool powerState = false;

// struct to store measurement from powersensor
struct {
  float voltage;
  float current;
  float power;
  float apparentPower;
  float reactivePower;
  float factor;
} powerMeasure;

// this is where you read from power sensor
// in this example, random values are used
void doPowerMeasure() {
  powerMeasure.voltage = random(2200,2300) / 10.0f;
  powerMeasure.current = random(1,20) / 10.0f;
  // powerMeasure.power = myIMU.readFloatAccelZ(); // powerMeasure.voltage * powerMeasure.current;
  // powerMeasure.apparentPower = myIMU.readFloatGyroZ(); // powerMeasure.power + (random(10,20)/10.0f);
}

void sendPowerSensorData() {
  // limit data rate to SAMPLE_EVERY_SEC
  static unsigned long lastEvent = 0;
  unsigned long actualMillis = millis();
  if (actualMillis - lastEvent < (SAMPLE_EVERY_SEC * 1000)) return;
  lastEvent = actualMillis;

  doPowerMeasure();

  // send measured data
  SinricProPowerSensor &myPowerSensor = SinricPro[POWERSENSOR_ID];
  bool success = myPowerSensor.sendPowerSensorEvent(powerMeasure.voltage, powerMeasure.current, powerMeasure.power, powerMeasure.apparentPower);
  if(!success) {
    Serial.printf("Something went wrong...could not send Event to server!\r\n");
  }
}

void setupWiFi() {
  Serial.printf("\r\n[Wifi]: Connecting");

  #if defined(ESP8266)
    WiFi.setSleepMode(WIFI_NONE_SLEEP); 
    WiFi.setAutoReconnect(true);
  #elif defined(ESP32)
    WiFi.setSleep(false); 
    WiFi.setAutoReconnect(true);
  #endif

  WiFi.begin(WIFI_SSID, WIFI_PASS);

  while (WiFi.status() != WL_CONNECTED) {
    Serial.printf(".");
    delay(250);
  }
  IPAddress localIP = WiFi.localIP();
  Serial.printf("connected!\r\n[WiFi]: IP-Address is %s\r\n", WiFi.localIP().toString().c_str());
}

void setupSinricPro() {
  SinricProPowerSensor &myPowerSensor = SinricPro[POWERSENSOR_ID];

  // setup SinricPro
  //SinricPro.restoreDeviceStates(true); // Uncomment to restore the last known state from the server.
  SinricPro.onConnected([](){ Serial.printf("Connected to SinricPro\r\n"); }); 
  SinricPro.onDisconnected([](){ Serial.printf("Disconnected from SinricPro\r\n"); });
  SinricPro.begin(APP_KEY, APP_SECRET);
}

// main setup function
void setup() {
  Serial.begin(BAUD_RATE);
  setupWiFi();
  setupSinricPro();
}

void loop() {
  SinricPro.handle();
  sendPowerSensorData();
}

[sivar2311]

After adding a few missing lines to your sketch above

#include <WiFi.h>
#include <SinricPro.h>
#include <SinricProPowerSensor.h>

const char* WIFI_SSID = "";
const char* WIFI_PASS = "";
const char* APP_KEY = "";
const char* APP_SECRET = "";
const char* POWERSENSOR_ID = "";
const int BAUD_RATE = 115200;
const int SAMPLE_EVERY_SEC = 60;

The sketch compiles fine:

Sketch uses 1091744 bytes (83%) of program storage space. Maximum is 1310720 bytes.
Global variables use 41360 bytes (12%) of dynamic memory, leaving 286320 bytes for local variables. Maximum is 327680 bytes.

Yes, I have those header lines. I used a new computer, reinstalled board/library, still getting this:

Hi,

1. Are you using Ubuntu or Mac?

2. Arduino IDE version

I will try on my local setup and try to replicate

[Pyro-E]

Hi,

Mac Arduino IDE 2.3.2

Tried 3 built-in examples with the same error.

[kakopappa]

Arduino IDE: 2.3.2 ESP32 Core: 3.0.2 MacMini: M1 - 13.6 SinricPro: 3.0.1

can compile the switch sketch with ESP32C6

[sivar2311]

Does a simple "Hello World" compile?

#include <Arduino.h>

void setup() {
  Serial.begin(115200);
  Serial.println("Hello World");
}

void loop{}

[Pyro-E]

Come on, Sivar :)

Ok it's uploading on a different mac user... No idea why. I'm online :)

[sivar2311]

You never know ... ;)

What I wanted to say: Does this error also occur with other sketches?

But it is strange that it works with another user.
