Hi there 
, I am trying to use an NFC shield on an Arduino Uno R3. I also installed the required libraries.
But when I try to verify my program with the NFC libraries, I get an error. Does someone know what I am doing wrong? I've included screenshots, which provide more information.
My code:
#include "Wire.h"
#include "PN532_I2C.h"
#include "PN532.h" // The following files are included in the libraries Installed
#include "NfcAdapter.h"
#define RESET (3)
PN532_I2C pn532_i2c(Wire);
NfcAdapter nfc = NfcAdapter(pn532_i2c); // Indicates the Shield you are using
void setup() {
Serial.begin(9600);
Serial.println("NFC Tag Writer"); // Serial Monitor Message
nfc.begin();
}
void loop() {
Serial.println("\nPlace an NFC Tag that you want to Record these Messages on!"); // Command for the Serial Monitor
if (nfc.tagPresent()) {
NdefMessage message = NdefMessage();
message.addTextRecord("My First NFC Tag Write"); // Text Message you want to Record
message.addUriRecord("http://allaboutcircuits.com"); // Website you want to Record
message.addTextRecord("Way to Go, It Worked!"); // Ednding Message for you to Record
boolean success = nfc.write(message);
if (success) {
Serial.println("Good Job, now read it with your phone!"); // if it works you will see this message
} else {
Serial.println("Write failed"); // If the the rewrite failed you will see this message
}
}
delay(10000);
}
(MOD EDIT)
Error messages are best copied and pasted into either code tags or quotes.
Very hard to read in pictures.
Just for future reference.

Error compiling for board Arduino/Genuino Uno.
One of the libs you are calling looks like it was specifically for the Arduino DUE which uses a different architecture to the UNO.
If you don't have a DUE then find and kill that one.
It can be daunting finding correct libraries and I often resort to the internet and particularly project that use exactly the same hardware approach to give me a better chance at success.
