plz.....tell about GPIO_support and usedefs........plz help me

My problem is that my GPIO code is compiling but when i link the following code ...i get errors,,,with gpio_open as undefined
Actually i wanted to ask whether GPIO_SUPPORT and USEDEFS have to be defined 1 before including csl-gpio.h......
becoz when i dont put #define gpio_support as 1,,, i get error as gpio_handle as undefined....
so what kind of such initializations have to be done before including csl_gpiohal.h......

#include
#define CHIP_DA610
#include "C6x.h"
#include "csl_chiphal.h"

#define GPIO_SUPPORT 1 //plz chk GPIO_SUPPORT and USEDEFS....................
#define _INLINE 1
//#define _GPIO_MOD_
//#define USEDEFS 1

#include "csl_gpiohal.h"

#include "csl_gpio.h"
#if defined(_TMS320C6201)
#define ALIGNED_ARRAY(ptr) _nassert((int) ptr % 8 == 0)

#elif defined( _chip_6201) || defined(_TMS320C6700)
#define ALIGNED_ARRAY(ptr) _nassert((int) ptr % 4 == 0)
#else
#define ALIGNED_ARRAY(ptr) /* empty */
#endif

main()
{
unsigned b=0;
GPIO_Handle hGpio;
hGpio = GPIO_open(GPIO_DEV0,GPIO_OPEN_RESET);
GPIO_pinEnable(hGpio,GPIO_PIN0);
GPIO_pinDirection(hGpio, GPIO_PIN0,GPIO_OUTPUT);
GPIO_pinWrite(hGpio,GPIO_PIN0,b);
}

I don't think you need to set GPIO_SUPPORT!

GPIO_SUPPORT ist by csl_chip_hal.h when you select the correct CHIP. The
same may be valid for USEDEFS.
