我创建一个新的Win32控制台应用程序作为一个空项目
我使用Visual Studio 2008 C运行 Windows 7 64位.我试图从本文的底部获取示例代码来构建: http://www.ddj.com/architect/207200659

我将CUDA Build Rule v2.3.0添加到项目的自定义构建规则中.在可用规则文件列表中只有一个复选框
我在源文件(文件夹/过滤器???)中创建moveArrays.cu
// moveArrays.cu // // demonstrates CUDA interface to data allocation on device (GPU) // and data movement between host (cpu) and device. #include <stdio.h> #include <assert.h> #include <cuda.h> int main(void) { float *a_h,*b_h; // pointers to host memory float *a_d,*b_d; // pointers to device memory int N = 14; int i; // allocate arrays on host a_h = (float *)malloc(sizeof(float)*N); b_h = (float *)malloc(sizeof(float)*N); // allocate arrays on device cudaMalloc((void **) &a_d,sizeof(float)*N); cudaMalloc((void **) &b_d,sizeof(float)*N); // initialize host data for (i=0; i<N; i++) { a_h[i] = 10.f+i; b_h[i] = 0.f; } // send data from host to device: a_h to a_d cudaMemcpy(a_d,a_h,sizeof(float)*N,cudaMemcpyHostToDevice); // copy data within device: a_d to b_d cudaMemcpy(b_d,a_d,cudaMemcpyDeviceToDevice); // retrieve data from device: b_d to b_h cudaMemcpy(b_h,b_d,cudaMemcpyDeviceToHost); // check result for (i=0; i<N; i++) assert(a_h[i] == b_h[i]); // cleanup free(a_h); free(b_h); cudaFree(a_d); cudaFree(b_d); }
当我建立我得到这些错误:

我可以编译并运行SDK随附的示例CUDA程序.我知道我在这里缺少一些简单的东西,但它是什么呢?
