Error compiling digital temperature sketch

Using Arduino IDE 1.x
1

Hi,

I am trying to compile a sketch (trying to read the temperature from the DHT11 sensor)

Sketch:

#include <dht.h>

dht DHT;

#define DHT11_PIN 7

void setup(){
Serial.begin(9600);
}

void loop()
{
int chk = DHT.read11(DHT11_PIN);
Serial.print("Temperature = ");
Serial.println(DHT.temperature);
Serial.print("Humidity = ");
Serial.println(DHT.humidity);
delay(1000);
}

And I get the following error Message:

Arduino:1.8.5 (Windows Store 1.8.10.0) (Windows 10), Kort"Arduino/Genuino Uno"

c:/program files/windowsapps/arduinollc.arduinoide_1.8.10.0_x86__mdqgnx93n4wtt/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference to `main'

collect2.exe: error: ld returned 1 exit status

exit status 1
Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Can anyone help me With this error?

Please use code tags (</> button on the toolbar) when you post code or warning/error messages. The reason is that the forum software can interpret parts of your code as markup, leading to confusion, wasted time, and a reduced chance for you to get help with your problem. This will also make it easier to read your code and to copy it to the IDE or editor. If your browser doesn't show the posting toolbar then you can just manually add the code tags:
[code]``[color=blue]// your code is here[/color]``[/code]
Using code tags and other important information is explained in the How to use this forum post. Please read it.

Try closing all Arduino IDE windows and then restart the Arduino IDE. That will clear the cache and hopefully fix the problem.
