Problem executing VirtualWire library in energia for MSP430

Hi, I am designing a remote controlled system using an arduino uno board and a msp430 launchpad with the ASK RF module (HT12E and HT12D ICs).

I am using the msp430 as the transmitter and the  arduino uno for the reciever because of requirements of my application.

Being familiar with Arduino, i am trying to use energia to program the msp430 with the VirtualWire library.

#include <VirtualWire.h>

int button = P2_2;
int transmit_pin = P2_1;
int a,counter=0;
char msg[4];
void setup()
{
    vw_set_tx_pin(transmit_pin);
    vw_setup(2000);       // Bits per sec
    pinMode(button,INPUT);
}


void loop()
{
  Serial.begin(9600);

  a=digitalRead(button);
  itoa(a,msg,10);
  Serial.println(a);
  if(a==1)
  counter=counter+1;
  vw_send((uint8_t *)msg, strlen(msg));
  vw_wait_tx();
  Serial.println("success");
  delay(1000);

}

This code, when used on the arduino, compiles, uploads and executes succesfully. The transmitter board LED blinks to indicate successful transmission of data. But when i use it on energia, there is an error-

 

F:\energia-0101E0013\hardware\msp430\libraries\VirtualWire\VirtualWire.cpp:16:26: fatal error: util/crc16.h: No such file or directory

compilation terminated.

any suggestions to get through with this error.

Or if the same code can be implemented using another library.

Cheers!
