CUDA 链接错误 - Visual Express 2008 - 由于(空)配置文件导致 nvcc 致命

在过去的 2 周里,我一直在广泛地寻找可能的解决方案来解决我的错误.我已经成功安装了 Cuda 64 位编译器(工具)和 SDK 以及 64 位版本的 Visual Studio Express 2008 和带有 Framework 3.5 的 Windows 7 SDK.我正在使用 Windows XP 64 位.我已确认 VSE 能够以 64 位编译,因为我使用以下网站上的步骤提供了所有 64 位选项:(因为 Visual Express 本身并不包含 64 位软件包)

在与上述链接相同的页面上的用户评论中可以找到 64 位安装的注册表更新.

我已经确认了 64 位编译能力,因为x64"可以从工具->选项->VC++ 目录"下的下拉菜单中获得,并且在 64 位编译不会导致整个项目被跳过".我已经包含了 64 位 cuda 工具、64 SDK 和 Visual Express (VCinamd64) 所需的所有目录.

这是我尝试在 64 位编译时收到的错误消息:

解决方案

我通过

解决了这个问题

  1. 安装 Windows SDK(不要忘记为 64 位操作系统选择所有 x64 选项)
  2. 在路径中包含c:Program Files (x86)Microsoft Visual Studio 10.0VCinamd64"
  3. 在目录c:Program Files (x86)Microsoft Visual Studio 10.0VCinamd64"中创建文件 vcvars64.bat,内容如下:调用C:Program FilesMicrosoft SDKsWindowsv7.1BinSetEnv.cmd"/x64

注意:我这样做是因为:

  1. 我使用的是 VC++ Express 2010
  2. 我在任何目录中都没有vcvars64.bat"??

I've been searching extensively for a possible solution to my error for the past 2 weeks. I have successfully installed the Cuda 64-bit compiler (tools) and SDK as well as the 64-bit version of Visual Studio Express 2008 and Windows 7 SDK with Framework 3.5. I'm using windows XP 64-bit. I have confirmed that VSE is able to compile in 64-bit as I have all of the 64-bit options available to me using the steps on the following website: (since Visual Express does not inherently include the 64-bit packages)

http://jenshuebel.wordpress.com/2009/02/12/visual-c-2008-express-edition-and-64-bit-targets/

The registry updates for 64-bit installation are found in a user comment on the same page as the above link.

I have confirmed the 64-bit compile ability since the "x64" is available from the pull-down menu under "Tools->Options->VC++ Directories" and compiling in 64-bit does not result in the entire project being "skipped". I have included all the needed directories for 64-bit cuda tools, 64 SDK and Visual Express (VCinamd64).

Here's the error message I receive when trying to compile in 64-bit:

Here's the simple code I'm trying to compile/run in 64-bit:

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <math.h>

#include <cuda.h>

void mypause () 
{ 
  printf ( "Press [Enter] to continue . . ." );
  fflush ( stdout );
  getchar();
} 

__global__ void VecAdd1_Kernel(float* A, float* B, float* C, int N)
{
 int i = blockDim.x*blockIdx.x+threadIdx.x;
 if (i<N)
  C[i] = A[i] + B[i]; //result should be a 16x1 array of 250s
} 

__global__ void VecAdd2_Kernel(float* B, float* C, int N)
{
 int i = blockDim.x*blockIdx.x+threadIdx.x;
 if (i<N)
  C[i] = C[i] + B[i]; //result should be a 16x1 array of 400s
}

int main()
{
 int N = 16;
 float A[16];float B[16];
 size_t size = N*sizeof(float);

 for(int i=0; i<N; i++) 
 {
  A[i] = 100.0;
  B[i] = 150.0;
 }

 // Allocate input vectors h_A and h_B in host memory
 float* h_A = (float*)malloc(size);
        float* h_B = (float*)malloc(size);
        float* h_C = (float*)malloc(size);

 //Initialize Input Vectors
 memset(h_A,0,size);memset(h_B,0,size);
 h_A = A;h_B = B;

 printf("SUM = %f
",A[1]+B[1]); //simple check for initialization

 //Allocate vectors in device memory
 float* d_A;
 cudaMalloc((void**)&d_A,size);
 float* d_B;
 cudaMalloc((void**)&d_B,size);
 float* d_C;
 cudaMalloc((void**)&d_C,size);

 //Copy vectors from host memory to device memory
 cudaMemcpy(d_A,h_A,size,cudaMemcpyHostToDevice);
 cudaMemcpy(d_B,h_B,size,cudaMemcpyHostToDevice);

 //Invoke kernel
 int threadsPerBlock = 256;
 int blocksPerGrid = (N+threadsPerBlock-1)/threadsPerBlock;
 VecAdd1(blocksPerGrid, threadsPerBlock,d_A,d_B,d_C,N);
 VecAdd2(blocksPerGrid, threadsPerBlock,d_B,d_C,N);

 //Copy results from device memory to host memory
 //h_C contains the result in host memory
 cudaMemcpy(h_C,d_C,size,cudaMemcpyDeviceToHost);

 for(int i=0; i<N; i++) //output result from the kernel "VecAdd"
 {
  printf("%f ", h_C[i] );
  printf("
");
 }
 printf("
");

 cudaFree(d_A); 
 cudaFree(d_B); 
 cudaFree(d_C);
 free(h_A);
 free(h_B);
 free(h_C);

 mypause();
 return 0;
}

解决方案

I solved the problem by

  1. installing Windows SDK (don't forget to choose all x64 options for 64 bit OS)
  2. include "c:Program Files (x86)Microsoft Visual Studio 10.0VCinamd64" in PATH
  3. create file vcvars64.bat inside directory "c:Program Files (x86)Microsoft Visual Studio 10.0VCinamd64" with following content: call "C:Program FilesMicrosoft SDKsWindowsv7.1BinSetEnv.cmd" /x64

Note: I did this because:

  1. I am using VC++ Express 2010
  2. I dont have "vcvars64.bat" in any directory ??
