A. Uno interfacing with SD Card

I was trying to interface my A. Uno with SD Card break out but the problem exist when I tried to compile/upload to uno. This are the compilling error

    compilation terminated.

I already added the library which is SdFat. Already tried including #include <WProgram.h> and #include <Arduino.h> still the same problem exist.

The coding

#include <SdFat.h>

// file system object
SdFat sd;

// create Serial stream
ArduinoOutStream cout(Serial);

// store error strings in flash to save RAM
#define error(s) sd.errorHalt_P(PSTR(s))
void setup() {
  // filename for this example
  char name[] = "APPEND.TXT";
  // pstr() stores strings in flash to save RAM
  cout << endl << pstr("Type any character to start\n");
  while (!Serial.available());

  // initialize the SD card at SPI_HALF_SPEED to avoid bus errors with
  // breadboards.  use SPI_FULL_SPEED for better performance.
  if (!sd.init(SPI_HALF_SPEED)) sd.initErrorHalt();

  cout << pstr("Appending to: ") << name;

  for (uint8_t i = 0; i < 100; i++) {
    // open stream for append
    ofstream sdout(name, ios::out | ios::app);
    if (!sdout) error("open failed");
    // append 100 lines to the file
    for (uint8_t j = 0; j < 100; j++) {
      // use int() so byte will print as decimal number
      sdout << "line " << int(j) << " of pass " << int(i);
      sdout << " millis = " << millis() << endl;
    // close the stream
    if (!sdout) error("append data failed");

    if (i % 25 == 0) cout << endl;
    cout << '.';
  cout << endl << "Done" << endl;
void loop() {}

You modified some file to make this change. You didn’t show us this modified file. We can only guess what you did, and I guess it wasn’t correct. What did I win?

Sorry updated, the code are direct copied from my lectures code.

Then he knows that he is years out of data get an upto date copy of the lib.
