Problem when I compile with touchsreen TFT 2.8

Hello everyone, I have a touchscreen TFT2.8, Arduino MEGA 2560. When I compile to display a series of graphic tests (website : LCD Test | 2.8" TFT Touch Shield | Adafruit Learning System ) I get messages error:

help me please ..

There are other errors reported by the Robot_Control library in the core folder. The Robot_Control library is where the Adafruit_LCD library is delivered. Adafruit does not name library files to match the class that the library implements., so finding the Adafruit_LCD library is going to be your job, after you delete the Robot_Control library.
