How to use cutLoadPGMub function to load image in CUDA 5.0?

Hello Everyone ,

I want to load PGM image file in CUDA 5.0 for this i have written the code as following:

#include <time.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <math.h>
#include <cuda.h>
#include <cutil.h>
#include

int main( int argc , char** argv)
{
/* ******************** setup work ***************************
/
unsigned int height;
unsigned int width;
unsigned char * d_resultPixels;
unsigned char * h_resultPixels;
unsigned char * h_pixels = NULL;
unsigned char * d_pixels = NULL;
char * srcPath = “C:/Users/Lenovo/Documents/Visual Studio 2010/Projects/CUDA1/CUDA1/lena.pgm”;
char * h_ResultPath = “C:/Users/Lenovo/Documents/Visual Studio 2010/Projects/CUDA1/CUDA1/lena1.pgm”;
char * d_ResultPath = “C:/Users/Lenovo/Documents/Visual Studio 2010/Projects/CUDA1/CUDA1/lena1.pgm”;
cutLoadPGMub(srcPath , &h_pixels , &width , &height);
int ImageSize = sizeof(unsigned char) * width * height;
h_resultPixels = (unsigned char )malloc(ImageSize);
cudaMalloc((void
)&d_pixels , ImageSize);
cudaMalloc((void**)&d_resultPixels , ImageSize);
cudaMemcpy(d_pixels , h_pixels , ImageSize , cudaMemcpyHostToDevice
);

printf(“Press enter to exit …\n”);
getchar();
}

but i got the error

1>main.cu.obj : error LNK2019: unresolved external symbol __imp__cutLoadPGMub@16 referenced in function _main.

Please suggest the solution.
