sim900 library is not working on the Mega

Using Arduino Programming Questions
1

Hi guys,

I am using the sim900 sms example on my Mega, I have changed the HWSerail.h to
#define MEGA

#ifndef HWSERIAL_H
#define HWSERIAL_H

#include "Arduino.h"
#include "Streaming.h"
#include <inttypes.h>

and GSM.h to
#ifndef GSM_H
#define GSM_H

//#define UNO
#define MEGA

The error I am getting when I compile it is

/Users/daniel/Documents/Arduino/libraries/SIM900/HWSerial.cpp: In member function 'size_t HWSerial::print(const __FlashStringHelper*)':
/Users/daniel/Documents/Arduino/libraries/SIM900/HWSerial.cpp:63:12: error: 'prog_char' does not name a type

The shield I am using

Thank you very much

The seller should update their library. The prog_char is no longer used in new arduino IDE (including newer version of avr gcc). You have to replace all prog_char with const char.
