I am getting errors while compiling basic example.

Sketch

#BEGIN
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager

void setup() {
    WiFi.mode(WIFI_STA); 
    Serial.begin(115200);
    //WiFiManager, Local intialization. Once its business is done, there is no need to keep it around
    WiFiManager wm;
    bool res;

    res = wm.autoConnect("AutoConnectAP","password"); // password protected ap

    if(!res) {
        Serial.println("Failed to connect");
        // ESP.restart();
    } 
    else {
        Serial.println("connected...yeey :)");
    }
}

void loop() {
    
}
#END

The same example compiles ok with esp8266.
