Getting errors while compiling the GSM test codes

hi everyone,

my objective: perfoming basic tests on "gsm/gprs modem" not shield.

i have gsm/gprs modem me , trying basics tests choose following code , code site

http://arduino.cc/en/tutorial/gsmtoolstestmodem#.uyvjx9soc7h
and code

code: [select]

/*

example test if modem working correctly.

circuit:
* gsm shield attached (using digital pins 2, 3, , 7)

// libraries
#include <gsm.h>

// modem verification object
gsmmodem modem;

// imei variable
string imei = "";

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

 // start modem test (reset , check response)
 serial.print("starting modem test...");
 if(modem.begin())
   serial.println("modem.begin() succeeded");
 else
   serial.println("error, no modem answer.");
}

void loop()
{
 // modem imei
 serial.print("checking imei...");
 imei = modem.getimei();

 // check imei response
 if(imei != null)
 {
   // show imei in serial monitor
   serial.println("modem's imei: " + imei);
   // reset modem check booting:
   serial.print("reseting modem...");
   modem.begin();
   // , check imei 1 more time
   if(modem.getimei() != null)
   {
     serial.println("modem functoning properly");
   }
   else
   {
     serial.println("error: getimei() failed after modem.begin()");
   }
 }
 else
 {
   serial.println("error: not imei");
 }
 // nothing:
 while(true);
}


to compile code have include gsm.h file, have downloaded following link

https://code.google.com/p/gsm-shield-arduino/source/browse/branches/gsmshield/gsm.h?r=102

here not adding file because header file contains many lines...

when compiling code getting following errors

code: [select]



gsm_imei_testing.cpp:9:1: error: 'gsmmodem' not name type
gsm_imei_testing.cpp: in function 'void setup()':
gsm_imei_testing.cpp:19:4: error: 'modem' not declared in scope
gsm_imei_testing.cpp: in function 'void loop()':
gsm_imei_testing.cpp:28:8: error: 'modem' not declared in scope


anyone reading post please me out how overcome error. , mistakes i've done please correct me...

where can gsm.h,sms.h , gprs related libraries can post link...

thanks in advance...
