CURAND库 - 编译错误 - 对函数的未定义引用

Question

我有以下代码,我试图使用nvcc编译.

码:

#include <stdio.h>
#include <stdlib.h>
#include <cuda.h>
#include <curand.h>

int main(void)
{
    size_t n = 100;
    size_t i;
    int *hostData;
    unsigned int *devData;
    hostData = (int *)calloc(n, sizeof(int));
    curandGenerator_t gen;
    curandCreateGenerator(&gen, CURAND_RNG_PSEUDO_MRG32K3A);
    curandSetPseudoRandomGeneratorSeed(gen, 12345);
    cudaMalloc((void **)&devData, n * sizeof(int));
    curandGenerate(gen, devData, n);
    cudaMemcpy(hostData, devData, n * sizeof(int), cudaMemcpyDeviceToHost);
    for(i = 0; i < n; i++)
    {
        printf("%d ", hostData[i]);
    }
    printf("\n");
    curandDestroyGenerator (gen);
    cudaFree ( devData );
    free ( hostData );
    return 0;
}

这是我收到的输出:

$ nvcc -o RNG7 RNG7.cu
/tmp/tmpxft_00005da4_00000000-13_RNG7.o: In function `main':
tmpxft_00005da4_00000000-1_RNG7.cudafe1.cpp:(.text+0x6c): undefined reference to `curandCreateGenerator'
tmpxft_00005da4_00000000-1_RNG7.cudafe1.cpp:(.text+0x7a): undefined reference to `curandSetPseudoRandomGeneratorSeed'
tmpxft_00005da4_00000000-1_RNG7.cudafe1.cpp:(.text+0xa0): undefined reference to `curandGenerate'
tmpxft_00005da4_00000000-1_RNG7.cudafe1.cpp:(.text+0x107): undefined reference to `curandDestroyGenerator'
collect2: ld returned 1 exit status

我最初的猜测是,由于某种原因,CURAND Library未正确安装或无法找到curand.h头文件.

请让我知道我应该寻找什么或如何解决我的问题.

谢谢!

@Wilo Maldonado:如果你还没有它,只需使用链接器标志-lcurand和-L/path/to/cuda/libs
