CUDA catkin / cmake-对`curandCreateGenerator`的未定义引用

如何解决CUDA catkin / cmake-对`curandCreateGenerator`的未定义引用

当我使用catkin编译CUDA项目时，我认为是链接器错误有问题。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，它正在使用c ++链接文件，它正在传递适当的标志，例如我在CURAND_FLAGS中定义的标志。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);

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);
}

使用catkin build cwru_cuda --verbose

构建

解决方法

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)
