如何编译推力和c ++项目？ [英] How to compile thrust and c++ project?
本文介绍了如何编译推力和c ++项目？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这里是项目结构（只是一个测试项目）：
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>简历;
};
sorter.h
#ifndef __SORTER_H__
#define __SORTER_H__
#include< iostream>
#include< thrust / device_vector.h>
#includesortbase.h
using namespace std;
template< class T>
void ttest（）
{cout<<tttttttttttttt; 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> *简历;
};
#endif
main.cpp / p>
#include< iostream>
#includeinclude / sorter.cu
using namespace std;
int main（int argc，char ** argv）
{
Sorter< int> * sorter = new Sorter< int>（）;
sorter-> test（）;
return 0;
}
我这样做：
nvcc -c sorter.cu
g ++ -c main.cpp -I / usr / local / cuda / include
g ++ sorter.o main。 o -o sorter
但第二步给出错误消息，大量的警告和错误消息。
谁可以帮助我？
如下所示的一些警告和错误消息：

解决方案
我认为问题是你正在从.cpp文件中包括.cu文件。推力代码只能从.cu文件使用，这些文件必须由NVCC编译，而不能由主机编译器g ++编译。因此，您需要将所有的Thrust和CUDA设备代码移动到可以从.cpp文件调用的函数中的.cu文件中。
I got big problems about the compile when I want to use thrust and c++ meanwhile.
Here is the project structure(just a test project):
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
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;
}
What I do like this:
nvcc -c sorter.cu
g++ -c main.cpp -I/usr/local/cuda/include
g++ sorter.o main.o -o sorter
but the second step gives the error message, a lot of warning and error message. who can help me? some warning and error message like these:

解决方案
I think that the problem is you are including your .cu file from a .cpp file. Thrust code can only be used from .cu files, which must be compiled by NVCC, not by the host compiler g++. So you need to move all of your Thrust and CUDA device code inside .cu files in functions that can be called from your .cpp files.
