please HELP me with my code

can some one look at my code and why I keep getting
compilation terminated.
exit status 1
Error compiling for board Arduino/Genuino Uno. thanks here is my code:
#include <Wire.h>
#include "rgb_lcd.h"

rgb_lcd lcd;
const int colorR = 0;
const int colorG = 0;
const int colorB = 0;

int delayTime = 100;

void setup() {
// put your setup code here, to run once:
lcd.begin(16, 2);
lcd.setRGB(colorR, colorG, colorB);
clearScreen();
}

void loop() {
// put your main code here, to run repeatedly:
lcd.setRGB(255 , 0, 0);
delay(delayTime);
lcd.setRGB(0 , 255, 0);
delay(delayTime);
lcd.setRGB(0 , 0, 255);
delay(delayTime);
}

void clearScreen() {
lcd.setCursor(0, 0);
lcd.print(" ");
lcd.setCursor(0, 1);
lcd.print(" ");
}

Where is the rest of the error message?

Where did you put that library when you downloaded it?
Did you restart the IDE?
