Error compiling for board Arduino/Genuino Uno

[BALROG877]

Hey Guys!!

I am still learning how to use Arduino and I recently started learning again after a few months of radio silence. My Arduino Uno board is a standard original one and not of any third party company. The board has been lying unused for about 6 months (Not sure whether this is relevant).

Anyway, today I tried a simple blink program from one of the examples and when I try to verify the code an error message at the bottom reads:

"Error compiling for board Arduino/Genuino Uno"

Followed by a whole bunch of incomprehensible error code (included in the inserted screenshot). The code, I repeat, is example code and therefore has no errors. I have also quadruple-checked both the board type and port. I have never ever come across this trouble before and I don't exactly know what the problem is.

It would be a great help if y'all could please help me overcome this troubleshooting. I'm pretty sure the problem is obvious but I just don't know about it (Being a noobie ). Thanks in advance.

Edit: The error occurs even when the board isn't connected so I guess the board has nothing to do with the problem.

Don't post screenshots of text! That is very unhelpful. When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar). It is almost never appropriate to post screenshots but in some cases it is helpful to post images. You should attach and embed the image following these instructions:

Sorry, I am new to the forum and I'm still finding my way around. Thanks for the feedback though. It was pretty informative and helpful.

This is my code (from the 'examples' tab in the Arduino coding software):

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}

And this is the error message shown below, headed by the words "Error compiling for board Arduino/Genuino Uno":

This report would have more information with

option enabled in File -> Preferences.

Looks like it's:

Cannot compile larger projects on macOS Sierra GM

The solution is simply to update to the latest version of the Arduino IDE, which you can download from:
