我正在使用 Ubuntu 12.10 并且也成功安装了 CUDA 5.0 及其示例工具包。我还运行了sudo apt-get install nvidia-cuda-toolkit
下面是我的 CUDA hello world 程序:
#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 */
编译时出现以下错误nvcc -g hello_world_cuda.cu -o hello_world_cuda.x

我还确保我使用 gcc 和 g++ 4.4 版(作为 4.7,CUDA 存在一些问题)
