C++ CUDA推力：：设备|类向量|错误

我是CUDA和推力图书馆的新手。我已经看了很多关于我的问题的例子和问题，但是，我无法转移解决方案

我有一个类

单元格

，它应该包含一个

树的向量

（另一个类）

这是我的

单元格.h

#pragma once

#include <thrust/host_vector.h>
#include <thrust/device_vector.h>
#include <thrust/generate.h>
#include <thrust/reduce.h>
#include <thrust/functional.h>




#include "Tree.h"

class Cell {
    int idx;
    float xmid, ymid;
    float dx, dy;
    int nTrees;
    thrust::host_vector<Tree> trees;
//  thrust::device_vector<Tree> trees;         <-- this is what I want
public:
     Cell();
    Cell(int, float, float, float, float, int);
    void set(int, float, float, float, float, int);
    void add(float, float, float);
    void add(float);
    void add();
    virtual ~Cell();
    void print();
    void copyToDev();
};

这两个类都在扩展名为

.cu

的文件中实现。在my

main.cu

中，我现在想初始化一个

单元格C

。鉴于上面的代码，我能够编译代码（使用Visual Studio 2013，我以前从未使用过，因此这可能是我的另一个问题）。 但是，如果我没有弄错的话，使用

host\u vector

我不会使用我的GPU。我想要的是使用

device\u vector

但是如果我用

device\u vector

而不是

host\u vector

编译代码，我会得到以下错误

减少到最小的部分。如果缺少进一步的信息，请告诉我。

如果您查看具有

推力：：系统：：cuda：：细节：：定义的文件，如错误消息所示，您将发现以下注释（）：

确保你真的使用了
nvcc
来编译你的程序，而不仅仅是试图在一个普通的
c++
项目中包含推力，这个项目是用visual studio的
cl
编译的。你是在创建一个Cell somewere的设备向量吗？你需要提供一个MCVE。您正在请求有关编译错误的帮助，但您甚至还没有显示导致错误的代码行。您能否在Visual Studio Nsight中详细说明如何执行此操作？事实证明，这就是问题所在。然而，我现在只能通过命令行在linux上编译它，而不能在VS中编译，因为我不知道如何配置VS以使用nvcc。
