如何編譯推力和C++項目？

當我想使用推力和C++的時候，我遇到了很大的編譯問題。如何編譯推力和C++項目？

下面是項目結構（只是一個測試項目）：

sortbase.h

#include<iostream> 
#include <thrust/device_vector.h> 
using namespace std; 

template<class T> 
class SortBase 
{ 
public: 
     void Init() 
     { 
     } 
     void resize(const int &x) 
     { 
       CV.resize(x); 
       cout<<"resize succeed!"<<endl; 
     } 
private: 
     thrust::device_vector<T> CV; 
};

sorter.h

#ifndef __SORTER_H__ 
#define __SORTER_H__ 
#include <iostream> 
#include <thrust/device_vector.h> 
#include "sortbase.h" 
using namespace std; 

template<class T> 
void ttest() 
{cout<<"tttttttttttttttt";cout<<endl;} 
     template<class KEY> 
     class Sorter 
     { 
     public: 
       Sorter():CV(NULL) 
       { 
         CV=new SortBase<KEY>(); 
       } 
       ~Sorter() 
       { 
         if (CV!=NULL) 
         { 
           delete CV; 
           CV=NULL; 
         } 
       } 
       __host__ __device__ 
       virtual bool operator()(const KEY& x,const KEY& y)const 
       { 
         return (x<y); 
       } 
       void test() 
       { 
         //ttest<KEY>(); 
         resize(5); 
       } 
     private: 
       void resize(const int &x) 
       { 
         CV->resize(x); 
         cout<<"resize: "<<x<<endl; 
       } 
     private: 
       SortBase<KEY> *CV; 
     }; 

#endif

的main.cpp

#include <iostream> 
#include "include/sorter.cu" 
using namespace std; 

int main(int argc,char **argv) 
{ 
     Sorter<int> *sorter=new Sorter<int>(); 
     sorter->test(); 
     return 0; 
}

我做的是這樣的：

nvcc -c sorter.cu 
g++ -c main.cpp -I/usr/local/cuda/include 
g++ sorter.o main.o -o sorter

但第二步給出了錯誤信息，很多警告和錯誤消息。誰能幫幫我？像這樣的一些警告和錯誤消息：

** **什麼錯誤訊息？ –

您是否使用CUDA安裝目錄的推力？ – geek

一些實例化錯誤，如下所示：/usr/local/cuda/include/thrust/detail/device/cuda/for_each.inl:93：錯誤：無效的應用程序sizeof –

我覺得現在的問題是要包括從.cpp文件的文件.CU。推力代碼只能從.cu文件中使用，必須由NVCC編譯，而不是由主編譯器g ++編譯。因此，您需要將所有Thrust和CUDA設備代碼移入可從.cpp文件調用的函數中.cu文件。

謝謝@harrism，這個問題解決了，我犯了一個愚蠢的錯誤。 –

很高興你解決了它。請接受我的答案，如果它解決了您的問題，或者如果解決方案是別的，請提供另一個答案。 – harrism

Harrism是對的。如果你要編譯使用GPU的文件時，你必須使用.cu的文件和nvcc像：

nvcc -o test test.cu
