thrust::device_vector signal无法编译问题记录

CUDA编程笔记

一、问题记录

正常编译时，无法编译

二、源码

#include <thrust/host_vector.h>
#include <thrust/device_vector.h>
#include <thrust/generate.h>
#include <thrust/sort.h>
#include <thrust/copy.h>
#include <thrust/random.h>

int main() {
  // Generate 32M random numbers serially.
  thrust::default_random_engine rng(1337);
  thrust::uniform_int_distribution<int> dist;
  thrust::host_vector<int> h_vec(32 << 20);
  thrust::generate(h_vec.begin(), h_vec.end(), [&] { return dist(rng); });

  // Transfer data to the device.
  thrust::device_vector<int> d_vec = h_vec;

  // Sort data on the device.
  thrust::sort(d_vec.begin(), d_vec.end());

  // Transfer data back to host.
  thrust::copy(d_vec.begin(), d_vec.end(), h_vec.begin());
}

三、解决方法

解决方法是将main.cpp修改为main.cu。
