c++ - CUDA catkin/cmake-对 `curandCreateGenerator`的 undefined reference

Question

我使用catkin编译CUDA项目时遇到了一个我认为是链接器错误的问题。下面是源代码的片段。当我尝试运行catkin build时出现错误:error

In function `curand_init(double*, int, int):
./src/cwru_cuda.cu undefined reference to `curandCreateGenerator'
./src/cwru_cuda.cu undefined reference to `curandSetPseudoRandomGeneratorSeed'

我检查了详细的生成输出，它使用c++链接文件，它传递了适当的标志，就像我在 CURAND_FLAGS中定义的那样。我不确定这里可能还有什么问题？我对构建工具不是很了解。
CURAND reference cwru_cuda.h

#include <cuda.h>
#include <cuda_runtime.h>
#include <curand.h>
#include <helper_cuda.h>
#include <device_launch_parameters.h>

void curand_init(double*, int, int);

cwru_cuda.cu

#include <cwru_cuda.h>

curandGenerator_t __curand_gen;
double* __curand_float_address;
size_t __curand_float_size;
int __curand_num_elems;

void curand_init(double* address, int numElements, int seed = 1234) {
    curandCreateGenerator(&__curand_gen, CURAND_RNG_PSEUDO_DEFAULT);
    curandSetPseudoRandomGeneratorSeed(__curand_gen, seed);
    __curand_num_elems = numElements;
    __curand_float_size = numElements * sizeof(double);
    cudaMallocManaged(&__curand_float_address, __curand_float_size);
}

用 catkin build cwru_cuda --verbose构建 build output

Answer 1

Robert Crovella在上面的comments中回答了这个问题。
我能够使用target_link_libraries()来设置满足依赖性的-lcurand和-lcublas。所以我将以下行添加到了CMakeLists.txt

target_link_libraries(cuda_vector_lib -lcublas -lcurand)
