将.cpp更改为 .cu 后，>> C++ 代码中无法识别基本操作数

Question

我很难弄清楚我的代码中发生了什么。任何帮助将不胜感激。这是我的标题 (.cuh(：

#include <map>
#include <string>
#include <iostream>
#include "SINS_constants.cuh"
using namespace std;
class SINS_inputManager
{
    public:
        static SINS_inputManager& getInstance()
        {
            static SINS_inputManager SINS_inputManager_singleton;
            return SINS_inputManager_singleton;
        }
        void parse(ifstream& cfgfile); // TODO Better read incoming variables, recognize by type in a single loop : template ?
    private:
        static SINS_inputManager* SINS_inputManager_singleton;
        map<string, string> options;
        SINS_inputManager();
        ~SINS_inputManager();
        SINS_inputManager(SINS_inputManager const&);    // not defined copy constructor
        void operator=(SINS_inputManager const&);       // not defined = operator

};

这是我的 .cu ：

#include "SINS_inputManager.cuh"
void SINS_inputManager::parse(ifstream& cfgfile)
{
    cout << "n";
    string id, eq, val;
    while(cfgfile >> id >> eq >> val)
    {
        if (id[0] == '#')
        {
            cfgfile.ignore(numeric_limits<streamsize>::max(), 'n'); // skip comments
            continue;
        }
        if (eq != "=") throw runtime_error("Syntax error in the parser. Each line should follow :n'unique parameter name' = 'value'nA commented line begins with a '#' symbol.nn");
        options[id] = val;
    }
    istringstream theStream;
    string string_temp;
    theStream.clear();
    theStream.str(options["INITIAL_INPUT"]);
    theStream >> string_temp;
    strcpy(INITIAL_INPUT, string_temp.c_str());
    theStream.clear();
    theStream.str(options["FINAL_OUTPUT"]);
    theStream >> string_temp;
    strcpy(FINAL_OUTPUT, string_temp.c_str());
    theStream.clear();
    theStream.str(options["NB_IONS"]);
    theStream >> NB_IONS;
    theStream.clear();
    theStream.str(options["VERBOSE"]);
    theStream >> VERBOSE;
    theStream.clear();
    theStream.str(options["TIME_MAX"]);
    theStream >> TIME_MAX;
    theStream.clear();
    theStream.str(options["DT_OBS"]);
    theStream >> DT_OBS;
    if(VERBOSE >= 1)
    {
        cout << "The parser has read the following configuration :n";
        typedef map<string, string>::iterator it_type;
        for(it_type iterator = options.begin(); iterator != options.end(); iterator++)
        {
            cout << "t" << iterator->first << " = " << iterator->second << "n";
        }
    }
}
// private constructor
SINS_inputManager::SINS_inputManager()
{
}
// private destructor
SINS_inputManager::~SINS_inputManager()
{
}

这是错误：

在将文件名更改为 CUDA 扩展名之前，它运行良好。我搜索了谷歌，发现这可能是字符串或字符串.h包含的问题，但我尝试了所有可能的组合，但没有成功。我做错了什么？

编辑：这是添加包含并在 .cu 中使用命名空间 std 后的新输出：

抱歉，不是完全相同的错误(仅适用于字符串(：

Answer 1

将下一个标头添加到 .cu 文件：

#include <fstream>
#include <limits>
#include <stdexcept>

Answer 2

尝试将这些行从 .cuh 移动到 .cu 文件中

#include <map>
#include <string>
#include <iostream>
using namespace std;

尤其是这条线using namespace std;.
