我正在尝试将以下基本代码(radix_sort_128x.cu
)合并到现有C
项目中:
#include <thrust/device_vector.h>
#include <thrust/copy.h>
#include <thrust/sort.h>
#include "cuda.h"
extern "C" {
#include "radix_sort_128x.h"
}
__host__ __device__ bool operator<(const mm128_t & lhs, const mm128_t & rhs)
{ return lhs.x < rhs.x; }
extern "C"
void radix_sort_128x_kernel(mm128_t* list, size_t n) {
thrust::device_vector<mm128_t> list_d(list, list + n);
thrust::sort(list_d.begin(), list_d.end());
thrust::copy(list_d.begin(), list_d.end(), list);
}
但是,当我尝试使用NVCC(nvcc -c -o radix_sort_128x.o radix_sort_128x.cu
)编译此文件时,出现以下错误:

看来我的任何#include
语句(使用Thrust标头)都会导致此错误,并且可能是由于C vs C ++冲突引起的。任何想法如何解决这个问题?我尝试将整个项目编译为C ++,但这并没有解决任何问题。提前致谢!
我的CUDA版本(10.1)与GCC版本(8.3.1)不兼容。我曾尝试将GCC降级到4.3.5,但没有意识到其中的符号链接/usr/local/cuda/include
将CUDA指向devtoolset-8
GCC版本8.3.1,而我的降级尝试失败了。
