Unable to connect Ardunio RedBoard to SunFounder RF1D-RC522

Using Arduino Programming Questions
#1

Trying to connect redboard to RFID so it can serve as a proximity sensor. Getting the vague "error compiling for board arduino/genuino uno" error with no other message and not sure where the problem is, any help would be much appreciated Currently the main issue is we are unable to find out where the output info is located.

  if (status == MI_OK)
  {
    Serial.print("The card's number is: ");
    memcpy(serNum, str, 5);
    rfid.showCardID(serNum);//show the card ID
    Serial.println();
    Serial.println();
  }
  delay(500);

  rfid.halt(); //command the card into sleep mode 
}

The code was taken from an online guide for a similar project but we cannot quite get it to work. We are unsure where the requested info is being printed to.

If any additional info is needed for a solution I will gladly provide whatever else might be required. Thank you!

What “output” are you referring to? The card serial number?

We are unsure where the requested info is being printed to.

What info have you requested?

The program writes to the serial port. You need some application on the PC that is reading the other end of the serial port, and displaying what it reads. The Serial Monitor application is one such application, and is easily started from the IDE.
