Stuck Getting "Exit Status 1" Error - Not Sure Why

For context, I am trying to create a line following robot using two motors and a Polulu QTR8 sensor array, I am a beginner to arduino but fancied the challenge. I will share my code, hopefully I can get some feedback and pointers on what I've done wrong.

#include<AFMotor.h> //Include Adafruit Motor Driver Shield Library
//create motor obejects
AF_DCMotor motor1(1, MOTOR12_1KHZ);
AF_DCMotor motor2(2, MOTOR12_1KHZ);


#define FIRST_SENSOR A0 // connect the sensor with analog pin A0
#define SECOND_SENSOR A1 // connect the sensor with analog pin A1
#define THIRD_SENSOR A2 // connect the sensor with analog pin A2
#define FOURTH_SENSOR A3 // connect the sensor with analog pin A3
#define FIFTH_SENSOR A4 // connect the sensor with analog pin A4
#define SIXTH_SENSOR A5 // connect the sensor with analog pin A5


void setup() {

  pinMode(FIRST_SENSOR, INPUT); // initialize first sensor as an inut
  pinMode(SECOND_SENSOR, INPUT); // initialize second sensor as as input
  pinMode(THIRD_SENSOR, INPUT); // initialize third sensor as as input
  pinMode(FOURTH_SENSOR, INPUT); // initialize fourth sensor as as input
  pinMode(FIFTH_SENSOR, INPUT); // initialize fifth sensor as as input
  pinMode(SIXTH_SENSOR, INPUT); // initialize sixth sensor as as input

}

void loop() {
  if (analogRead(SECOND_SENSOR) <= 100 && !analogRead(FIRST_SENSOR) <= 100) //compare both sensor value to set the direction
  {
    motor1.run(FORWARD); // run motor1 clockwise
    motor1.setSpeed(255); // set motor1 speed 50 percent
    motor2.run(BACKWARD); // run motor2 clockwise
    motor2.setSpeed(255); // set motor2 speed  percent

  }
  else if (!analogRead(SECOND_SENSOR) >= 100 && !analogRead(FIRST_SENSOR) <= 100) //compare both sensor value to set the direction
  {
    motor1.run(FORWARD); // run motor1 clockwise
    motor1.setSpeed(255); // set motor1 speed 100 percent
    motor2.run(FORWARD); // run motor2 anti-clockwise
    motor2.setSpeed(255); // set motor2 speed 100 percent


  }
  else if (analogRead(SECOND_SENSOR) >= 100 && !analogRead(FIRST_SENSOR) >= 100) //compare both sensor value to set the direction
  {
    // motor1.run(BACKWARD); // run motor1 anti-clockwise
    //motor1.setSpeed(255); // set motor1 speed 100 percent
    //motor2.run(BACKWARD); // run motor2 clockwise
    //motor2.setSpeed(255); // set motor2 speed 100 percent

  }
  else if (!analogRead(SECOND_SENSOR) <= 100 && !analogRead(FIRST_SENSOR) >= 100) //compare both sensor value to set the direction
  {
    //stop all the motors
    motor1.run(RELEASE);
    motor2.run(RELEASE);

  }
}

where do you see an "Exit Status 1" Error" ?

the exclamation point (!) in the second part of your if is probably not doing what you think. read about operator priority or use parenthesis or just use > instead of <=``if (analogRead(SECOND_SENSOR) <= 100 && !analogRead(FIRST_SENSOR) <= 100)

Having made those changes I still get the error. It simply just says it has an "Error compiling for board Arduino/Genuino Uno"

I'm getting more and more frustrated by it.

Post your updated code, otherwise the frustration will spread.

Did you forget to install the "Adafruit Motor Shield library"? Check with Tools->Manage Libraries...
