【问题描述】：

我在 cuda 中有一个编译错误，我想知道为什么会发生这个错误？ 我想知道我的 cuda 是否会在 2DArray 中运行以进行图像处理

我的代码是

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include<cuda.h>
#include<cuda_runtime.h>
#include "device_launch_parameters.h"
#include<iostream>
using namespace std ;

#define BLOCK_WIDTH 16


__global__ void kernel(int *d_A, size_t pitch, int rows, int cols)
 //compute the row
 int r = blockIdx.y*blockDim.y+threadIdx.y;
 //compute the column
  int c = blockIdx.x*blockDim.x+threadIdx.x;

  if((r < rows) && (c < cols))
  //   // update the pointer to point to the beginning of the row
   //int *Row = (int*)((char*)d_A + r*pitch);
  int *Row = (int*)((char*)d_A);
  int elem = Row[c];
  printf("%d ", elem);
  
  


 void test(int **A, int rows, int cols)
 int *d_A;
 size_t pitch;

 cudaMallocPitch((void**)&d_A, &pitch, sizeof(int)*cols, rows);

 cudaMemcpy2D(d_A, pitch, A, sizeof(int)*cols, sizeof(int)*cols, rows,            cudaMemcpyHostToDevice);

 //Define grid and block size
 int Yblocks = rows / BLOCK_WIDTH;
 if(rows % BLOCK_WIDTH) Yblocks++;
 int Xblocks = cols / BLOCK_WIDTH;
  if(cols % BLOCK_WIDTH) Xblocks++;
  //  cout << Yblocks << "," << Xblocks << endl;
 dim3 dimGrid(Yblocks, Xblocks, 1);
 dim3 dimBlock(BLOCK_WIDTH, BLOCK_WIDTH, 1);
  //Run kernel
 kernel<<<dimGrid, dimBlock>>>(d_A, pitch, rows, cols);

cudaMemcpy2D(A, sizeof(int)*cols, d_A, pitch, sizeof(int)*cols, rows,     cudaMemcpyDeviceToHost);

 cudaFree(&d_A);
 


int main()
 int rows = 2;
   int cols = 2;

   int **A;
  A = new int*[rows];
  for(int i = 0; i < rows; ++i) 
   A[i] = new int[cols];
    for(int j = 0; j < cols; ++j)
     A[i][j] = i+2;
     

   test(A, rows, cols);

  for(int i = 0; i < rows; ++i)
   for(int j = 0; j < cols; ++j)
     cout << A[i][j] << " ";
    cout << "\n";
    

    for(int i = 0; i < rows; ++i) delete[] A[i];
    delete[] A;

   return 0;
   

我的笔记本电脑里有： NVIDIA CUDA 示例 7.5 , NVIDIA CUDA 工具包 7.5 , NVIDIA CUDA 工具包 v5(64), NVIDIA CUDA 工具 SDK v4.0 , NVIDIA GPU 计算 SDK 4 , NVIDIA 显卡驱动 306.94 , NVIDIA Nsigth 视觉工作室版 5.1.0.10602， 视觉工作室 2010 , 英伟达 GeForce 9300M GS , 驱动器型号：WDDM 1.1， DDI 版本：10 , 窗户 7

我有这个错误

我尝试了很多东西，但没有成功：

How to Compile CUDA App is Visual Studio 2010?

但不工作

【参考方案1】：

我觉得可能和这个奇怪的值有关

nvcc.exe  .......  --compile -1  .......
nvcc : fatal error : Unknown option '1'

【讨论】：

那么我应该怎么做才能修复它？？plz
