collect2.exe: fatal error: cannot find 'ld'

Using Arduino IDE 1.x

CAN SOMEONE PLEASE HELP ME ASAP! I NEED HELP WITH MY COMPILATION OF SKETCH. I HAVE RE-INSTALLED THE ARDUINO IDE, BUT STILL THE SAME PROBLEM OCCUR.
IT STATES: collect2.exe: fatal error: cannot find 'ld'

HERE IS MY CODE:
#define BLYNK_PRINT DebugSerial
// You could use a spare Hardware Serial on boards that have it (like Mega)

#include <SoftwareSerial.h>
SoftwareSerial DebugSerial(2, 3); // RX, TX

#include <Arduino.h>

int ledPin2 = 12; //Green
int ledPin3 = 11; //Red
int ledPin4 = 10; //Green
int ledPin5 = 9; //Red
int ledPin6 = 8; //Green
int ledPin7 = 7; //Red
int ledPin8 = 6; //Green
int buzzPin = 4;
int inputPin = 2; // choose the input pin (for PIR sensor)
int inputPin2 = 3; // choose the input pin (for PIR sensor)
int pirState = 0; // we start, assuming no motion detected
int val = 0; // variable for reading the pin status
bool buzz = false;

//---------------------------------------------------------------------------------------//

#include <BlynkSimpleStream.h>
SimpleTimer timer;

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).

//Attach termnal widget
WidgetTerminal terminal(V1);

void setup()
{

DebugSerial.begin(9600);

// Blynk will work through Serial
// Do not read or write this serial manually in your sketch
Serial.begin(9600);
Blynk.begin(Serial, auth);

timer.setInterval(100, activate);
}

}

}
}

PLEASE HELP!

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.

When your code requires a library that's not included with the Arduino IDE please always post a link (using the chain link icon on the toolbar to make it clickable) to where you downloaded that library from or if you installed it using Library Manger(Sketch > Include Library > Manage Libraries) then say so and state the full name of the library.

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).

Sounds like a corrupted install. On my Win8 system, ld (ld.exe) can be found in C:\Program Files (x86)\Arduino\hardware\tools\avr\avr\bin

Did it work before?

I have the same problem. Kept on uninstalling and reinstalling and there was no solution. Quit my antivirus, same problem. I don't know what's wrong. Hope someone could help.

Here's my error code. It shows the same thing no matter what code I put in, including the built-in examples.

Reply #2 provides some info where ld.exe should be.
