complier error

i keep getting error message " collect2.exe: error: ld returned 1 exit status. using library liquidcrystal @ version 1.0.5 in folder: c:\program files (x86)\arduino\libraries\liquidcrystal exit status 1
error compiling board arduino/genuino uno. "

i've looked online, can't me.

please help!
 
thanks in advance.

ps. here program. (it not complete.)

code: [select]



// lcd display
// include library
#include <liquidcrystal.h>

// initialize library numbers of interface pins
liquidcrystal lcd(4, 6, 10, 11, 12, 13);


void setup()
{
  // set lcd's number of columns , rows:
  lcd.begin(16, 2);
  lcd.print("hello! is  ");
 
  lcd.setcursor(0,14);
  lcd.print("an arduino.     "); 
  delay(3000);
 
  lcd.setcursor(0,0);
  lcd.print("get arduino!");

  // loop blinking.
  int x = 0;
  {
    lcd.setcursor(0,14);
    lcd.print("coding fun!");
    delay(1000);
    lcd.setcursor(0,5);
    lcd.print("hello");
    lcd.setcursor(0,14);
    lcd.print("              ");
    delay(1000);
    x++;
  } while(x != 5);
}

void display()
{
  lcd.setcursor(0,0);
  lcd.print("the things ");
 
  lcd.setcursor(1,15);
  lcd.print("can with    ");
 
  lcd.setcursor(0,15);
  lcd.print("               ");
 
  lcd.setcursor(0,14);
  lcd.print("code pretty ");
}



you need @ full compiler output, not couple lines @ end. depending on how have console window(black window @ bottom of arduino ide window) sized may need scroll see all. relevant part like:

code: [select]

c:\program files (x86)\arduino-1.8.0\hardware\arduino\avr\cores\arduino/main.cpp:46: undefined reference `loop'
so problem have no loop function in sketch. every sketch must have loop function if it's empty. more information see:
https://www.arduino.cc/en/reference/loop

so can make sketch compile adding lines:

code: [select]

void loop() {
}
outside of of other functions.

when want forum error need give enough information you. means need full compiler output. when encounter error see button on right side of orange bar "copy error messages". click button , paste error forum using code tags.
