GSM library an Software serial library error

hello
i have 2 codes
the first code send sms through gsm module

code: [select]


#include <gsm.h>

#define pinnumber ""

// initialize library instance
gsm gsmaccess; // include 'true' parameter debug enabled
gsm_sms sms;

// char array of telephone number send sms
// change number 1-212-555-1212 number
// have access to
char remotenumber[20]= "01145445380"; 

// char array of message
string txtmsg="test";

void setup()
{
  // initialize serial communications
  serial.begin(9600);

  serial.println("sms messages sender");

  // connection state
  boolean notconnected = true;

  // start gsm shield
  // if sim has pin, pass parameter of begin() in quotes
  while(notconnected)
  {
    if(gsmaccess.begin(pinnumber)==gsm_ready)
      notconnected = false;
    else
    {
      serial.println("not connected");
      delay(1000);
    }
  }
  serial.println("gsm initialized");
  sendsms();
}

void loop()
{
// nothing see here
}

void sendsms(){

  serial.print("message mobile number: ");
  serial.println(remotenumber);

  // sms text
  serial.println("sending");
  serial.println();
  serial.println("message:");
  serial.println(txtmsg);

  // send message
  sms.beginsms(remotenumber);
  sms.print(txtmsg);
  sms.endsms();
  serial.println("\ncomplete!\n"); 
}


and second read latitude , longtude gps module

code: [select]

#include <tinygps.h>

  // every 1 seconds print update
  while (millis() - start < 1000)
  {
    if (feedgps ()){
      newdata = true;
    }
  }
  if (newdata)
  {
    gpsdump(gps);
  }
}

bool feedgps(){
  while (gps.available())
  {
    if (gps.encode(gps.read()))
      return true;
  }
  return 0;
}

void gpsdump(tinygps &gps)
{
  //byte month, day, hour, minute, second, hundredths;
  gps.get_position(&lat, &lon);
  lat = lat;
  lon = lon;
  {
    feedgps(); // if don't feed gps during long routine, may drop characters , checksum errors
  }
}





when merge 2 codes send latitude , longtude gps phone through gsm
there error mean can't use software serial library , gsm library in same code

so can use gps module?
can 1 me please

you using pin 2 & 3 in both cases.. gsm modem uses 2&3 tx & rx.
use different set of pins gps module.
