nvcc/CUDA 6.5&c ++ 11(未来) - gcc 4.4.7

Question

当我编译包含设计C++ 11的以下代码时,我得到错误 - 它不编译.我试过不同的旗帜,但我还没有找到解决方案.

我的设置:CUDA 6.5,gcc 4.4.7我无法更改设置.我怎么还能做这个工作？

#include <stdio.h>
#include <vector>
#include "KD_tree.h"
#include "KD_tree.cpp"
#include <iostream>
#include <algorithm>
#include <cmath>
#include <future>
#define MYDEVICE 0

using namespace std;


int main()
{
    //do something..... 

    cudaDeviceProp devProp;
    cudaGetDeviceProperties(&devProp, MYDEVICE);
    printDevProp(devProp);
    int max_threads = devProp.warpSize;

   //do something else ... 

    return 0;
}

我尝试使用不同的标志进行编译:

nvcc -std=c++11 cudaMain.cu KD_tree.cpp -arch=sm_20 -o tree.out
In file included from cudaMain.cu:14:
simple_kd_tree.h:12:19: warning: extra tokens at end of #include directive
cudaMain.cu:19:18: error: future: No such file or directory


nvcc --std=c++11 cudaMain.cu KD_tree.cpp -arch=sm_20 -o tree.out
In file included from cudaMain.cu:14:
simple_kd_tree.h:12:19: warning: extra tokens at end of #include directive
cudaMain.cu:19:18: error: future: No such file or directory


nvcc --std=c++11 cudaMain.cu KD_tree.cpp -arch=sm_20 -c -o tree.out
nvcc fatal   : A single input file is required for a non-link phase when an outputfile is specified

我是否必须拆分c ++部分？我该怎么做呢？

在CUDA 7.0中正式添加了C++ 11支持.并且您需要GCC 4.7或更高版本才能获得C++ 11支持.详情请见:http://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#cuda-compiler-new-features
