ezLCD3 does not name a type

Hello!
I just buyed an arduino and the arLCD touchscreen, and as I wanted to download the little game “tic tac toe” directly from the display memory, and programmed on the “arduino programmer” and verified, it told me a message in orange on the bottom:
ezLCD3 does not name a type

What do I have to do? Thanks

P.s.: this is the beginning of the code:

#include <ezLCDLib.h>

#define LED_PIN 13

ezLCD3 lcd;

volatile boolean ezLCDInt = false; // flag to indicate interrupt
unsigned int gridx ={98, 172, 246, 98, 172, 246, 98, 172, 246};
unsigned int gridy ={18, 18, 18, 92, 92, 92 , 166, 166, 166};

unsigned int linesx={166,166, 241, 241 ,92, 317 ,92,317 };
unsigned int linesy={10, 235, 10 , 235 ,86, 86 ,160,160 };

int temp =0;
bool turn =1 ;
bool x = 1;
bool o = 0;
char winner =false;
unsigned char gameBoard[9]={5,5,5,5,5,5,5,5,5};
unsigned long touch;
void setup

Hi Alexdut68,

You probably didn't get that library or didn't tell IDE where to find it.

Oh ok! Thanks MAS3, but how can I do/change this? I'm really not a professionnal with programming...

Hi Alexdut68

When you downloaded the tictactoe program, was there also a folder called "ezLCDLib"?

The folder should contain files named "ezLCDLib.h" and "ezLCDLib.cpp", as well as probably a sub-folder called "examples".

If you can find the "ezLCDLib" folder, here are the instructions on how to load it into the Arduino IDE (which you called the "programmer").

http://arduino.cc/en/Guide/Libraries

Once it is loaded, try compiling the tictactoe program again.

Thank you very much Hackscribble! I understand now! I will try it as soon as possible!

Best regards, Alex
