为CUDA编译Hello world程序时出错

Question

I am using Ubuntu 12.10 and have sucessfully installed CUDA 5.0 and its sample kits too. I have also run sudo apt-get install nvidia-cuda-toolkit Below is my hello world program for CUDA:

#include <stdio.h>  /* Core input/output operations                         */
#include <stdlib.h> /* Conversions, random numbers, memory allocation, etc. */
#include <math.h>   /* Common mathematical functions                        */
#include <time.h>   /* Converting between various date/time formats         */
#include <cuda.h>   /* CUDA related stuff                                   */


__global__ void kernel(void) {
}

/* MAIN PROGRAM BEGINS */
int main(void) {

  /* Dg = 1; Db = 1; Ns = 0; S = 0 */
  kernel<<<1,1>>>();

  /* PRINT 'HELLO, WORLD!' TO THE SCREEN */
  printf("\n  Hello, World!\n\n");

  /* INDICATE THE TERMINATION OF THE PROGRAM */
  return 0;
}
/* MAIN PROGRAM ENDS */

The following error occurs when I compile it with nvcc -g hello_world_cuda.cu -o hello_world_cuda.x

/tmp/tmpxft_000033f1_00000000-13_hello_world_cuda.o: In function `main':

collect2: ld returned 1 exit status

I am also making sure that I use gcc and g++ version 4.4 ( As 4.7 there is some problem with CUDA)

I think, these links will help you.

Video demo of installation of Developer Drivers

Use the same command lines to install toolkit and sdk.

You need to change the directories when you open terminal every time. Those instructions are given in page-11 of Linux Installation

Before everything, you need to download the .run files from the Developers Page.
