Problem implements MySensors lib

[Adam Gliński]

Hi
I have trable to implement the mysensors lib i try programing DHT 22 on my mini but i cant
default sketch:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * DESCRIPTION
 * This sketch provides an example how to implement a humidity/temperature

#include <SPI.h>
#include <MySensor.h>  
#include <DHT.h>  

#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define HUMIDITY_SENSOR_DIGITAL_PIN 3
unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)

MySensor gw;
DHT dht;
float lastTemp;
float lastHum;
boolean metric = true; 
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);


void setup()  
{ 
  gw.begin();
  dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN); 

  // Send the Sketch Version Information to the Gateway
  gw.sendSketchInfo("Humidity", "1.0");

  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID_HUM, S_HUM);
  gw.present(CHILD_ID_TEMP, S_TEMP);
  
  metric = gw.getConfig().isMetric;
}

void loop()      
{  
  delay(dht.getMinimumSamplingPeriod());

  float temperature = dht.getTemperature();
  if (isnan(temperature)) {
      Serial.println("Failed reading temperature from DHT");
  } else if (temperature != lastTemp) {
    lastTemp = temperature;
    if (!metric) {
      temperature = dht.toFahrenheit(temperature);
    }
    gw.send(msgTemp.set(temperature, 1));
    Serial.print("T: ");
    Serial.println(temperature);
  }
  
  float humidity = dht.getHumidity();
  if (isnan(humidity)) {
      Serial.println("Failed reading humidity from DHT");
  } else if (humidity != lastHum) {
      lastHum = humidity;
      gw.send(msgHum.set(humidity, 1));
      Serial.print("H: ");
      Serial.println(humidity);
  }

  gw.sleep(SLEEP_TIME); //sleep a bit
}


But  i have problem to compilate

HumiditySensor:39: error: 'MySensor' does not name a type
HumiditySensor:44: error: 'MyMessage' does not name a type
HumiditySensor:45: error: 'MyMessage' does not name a type
HumiditySensor.ino: In function 'void setup()':
HumiditySensor:50: error: 'gw' was not declared in this scope
HumiditySensor:57: error: 'S_HUM' was not declared in this scope
HumiditySensor:58: error: 'S_TEMP' was not declared in this scope

HumiditySensor:85: error: 'gw' was not declared in this scope
HumiditySensor:85: error: 'msgHum' was not declared in this scope
HumiditySensor:90: error: 'gw' was not declared in this scope

what i do wrong i add my sensors on MyDocuments/Arduino/libraries
