Hi friends,
I installed a library for reading and writing csv file
been I compiled this example

// Read CSV
csv.gotoBeginOfFile();
int bufferSize = 5;
// Good practice is declare buffer larger by one then need
// and put null char as end element. It is prevent by
// overbuffer.
char buffer[bufferSize + 1];
buffer[bufferSize] = '\0';
int numBuffer = 0;
csv.readField(buffer, bufferSize);
Serial.println(buffer);
csv.nextField();
csv.readField(buffer, bufferSize);
Serial.println(buffer);

Arduino answered me with this letter
Compilation error for Arduino / Genuino Mega or Mega 2560 board
Plz, help me to solve this problem
