i'm so so exhausted . now i'm using the csl for my c5515 eZdsp development board. i newly ceate a project with runtime support libary choice of "automitic" and then added "C:\Program Files\TMS320C55XXCSL-LOWPWR\c55xx_csl\inc" and "C:\Program Files\TMS320C55XXCSL-LOWPWR\c55xx_csl\src" into my include options.
in my project, i added just mian.c the code is :
#include <stdio.h>
#include <csl_general.h>
#include "csl_gpio.h"
CSL_GpioObj gpioObj;
GPIO_Handle hGpio;
CSL_Status status;
CSL_GpioPinConfig gpioPinConfig;
/******************************************************************
main.c
*****************************************************************/
void mian(void)
{
unsigned short int buffer = 0;
hGpio = GPIO_open(&gpioObj,&status);
if ((NULL == hGpio)||(status != CSL_SOK))
{
printf("can not open gpio !");
}
GPIO_reset(hGpio);
gpioPinConfig.direction = CSL_GPIO_DIR_OUTPUT;
gpioPinConfig.pinNum = CSL_GPIO_PIN14;
gpioPinConfig.trigger = CSL_GPIO_TRIG_CLEAR_EDGE;
GPIO_configBit(hGpio,&gpioPinConfig);
GPIO_write(hGpio,CSL_GPIO_PIN14,buffer);
}
but i got link problem like this :
undefined first referenced
symbol in file
--------- ----------------
_main C:\Program Files\Texas Instruments\ccsv4\tools\compiler\C5500 Code Generation Tools 4.3.8\lib\rts55x.lib<args_main.obj>

error: errors encountered during linking; "Gpio.out" not built

i tried a lot to fix this problem. and now i 'm a little exhausted. what is the problem ?
PLEASE HELP ME
