CUDA链接错误 - Visual Express 2008 - nvcc致命由于（null）配置文件 [英] CUDA linking error - Visual Express 2008 - nvcc fatal due to (null) configuration file
问题描述
我一直在寻找一个可能的解决方案，我的错误过去2周。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Windows 7 SDK与Framework 3.5。我使用Windows XP 64位。我已经确认VSE能够在64位编译，因为我有所有的64位选项可用我使用下面的网站上的步骤：（因为Visual Express本身不包括64位包） p>

64位安装的注册表更新位于与上述链接相同的页面上的用户注释中。
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64位编译不会导致整个项目被跳过。我已经包括所有需要的目录64位的cuda工具，64 SDK和Visual Express（\VC\bin\amd64）。
这里是错误信息我试图在64位编译时收到：

- 安装Windows SDK（不要忘记为64位操作系统选择所有x64选项）
- 在PATH中包含c：\Program文件（x86）\ Microsoft Microsoft Visual Studio 10.0 \VC\bin\amd64
- 在目录c：中创建文件vcvars64.bat \Program Files（x86）\Microsoft Visual Studio 10.0 \VC\bin\amd64，包含以下内容：
callC：\Program Files \ Microsoft SDKs \Windows \v7。 1 \Bin\SetEnv.cmd/ x64
注意：我这样做是因为：
- 我使用VC ++ Express 2010
- 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 (\VC\bin\amd64).
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 ()

}
__global__ void VecAdd2_Kernel(float* B, float* C, int N)

int i = blockDim.x*blockIdx.x+threadIdx.x;
if (i<N)

}
int main()
{
int N = 16;
float A[16];float B[16];
size_t size = N*sizeof(float);
for(int i=0; i<N; i++)

// Allocate input vectors h_A and h_B in host memory

memset(h_A,0,size);memset(h_B,0,size);
h_A = A;h_B = B;
printf("SUM = %f\n",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);

printf("\n");
cudaFree(d_A);
cudaFree(d_B);
cudaFree(d_C);
free(h_A);
free(h_B);
free(h_C);
mypause();
return 0;
}
I solved the problem by
- installing Windows SDK (don't forget to choose all x64 options for 64 bit OS)
- include "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64" in PATH
- create file vcvars64.bat inside directory "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64" with following content: call "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" /x64
Note: I did this because:
- I am using VC++ Express 2010
- I dont have "vcvars64.bat" in any directory ??
