Did you download the TFT?
That's the problem, use the included TFT that's already part of TeensyDuino install.

Did you use the UTFT that comes with the Teensyduino install, or did you download it from a download site. The earliest version of the library installation used this segment to show the #include files:

#include <OpenAudio_ArduinoLibrary.h> //https:/github.com/chipaudette/OpenAudio_ArduinoLibrary
#include <Adafruit_GFX.h>???? // https://github.com/adafruit/Adafruit-GFX-Library
#include <Audio.h>??????????? // https://github.com/PaulStoffregen/Audio
#include <RA8875.h>?????????? // Download fron hamradiodesigns.com
#include <Rotary.h>?????????? // https://github.com/brianlow/Rotary
#include <SerialFlash.h>????? // https://github.com/PaulStoffregen/SerialFlash
#include <Time.h>???????????? // https://github.com/PaulStoffregen/Time
#include <TimeLib.h>????????? // Part of the Stoffregen lib, gives backward compatibiliity
#include <TimerOne.h>???????? // Distributed with Teensy
#include <UTFT.h>???????????? // http://www.rinkydinkelectronics.com/library.php?id=51
#include <URTouch.h>????????? // http://www.rinkydinkelectronics.com/library.php?id=92
#include <UTFT_Buttons.h>???? // http://www.rinkydinkelectronics.com/library.php?id=61

However, since that document was written, PJRC has changed the libraries that it distributes with the Teensyduino. Compare the list above with the most current list:

#include <OpenAudio_ArduinoLibrary.h> // http://hamradiodesigns.com/index.php/content/
#include <Adafruit_GFX.h>???? // Now supplied with Teensy Library install
#include <Audio.h>??????????? // Now supplied with Teensy Library install
#include <RA8875.h>?????????? // http://hamradiodesigns.com/index.php/content/
#include <Rotary.h>?????????? // https://github.com/brianlow/Rotary
#include <SerialFlash.h>????? // Now supplied with Teensy Library install
#include <Time.h>???????????? // Now supplied with Teensy Library install
#include <TimeLib.h>????????? // Now supplied with Teensy Library install
#include <TimerOne.h>???????? // Now supplied with Teensy Library install
#include <UTFT.h>???????????? // Now supplied with Teensy Library install
#include <URTouch.h>????????? // http://www.rinkydinkelectronics.com/library.php?id=92
#include <UTFT_Buttons.h>???? // http://www.rinkydinkelectronics.com/library.php?id=61

Notice how many are now supplied with the Teensyduino, which means you do NOT (should not) use the old install list. See if this fixes your problem.

Good morning,

Tried my first compile and got unexpected error, "

Have I missed a define statement that needs to be changed or do I have

corrupt UTFT lib?

Any help would be greatly appreciated.
