错误:候选构造函数(隐式移动构造函数）不可行:没有已知的转换

我创建了一个具有以下定义的类文件"Heuristic.hpp"：

#include <iostream>
#include <vector>
#include <chrono>
#include <cstdint>
#include <cmath>
#include <limits>
#include "csv.hpp"
#include "mdl.hpp"
class Computation {
public:
     Computation(const int n,const int noRows, MDL mdl) {

        std::cout << "Constructor successfully made" << std::endl;
    }
    double heuristic() {
        return 0;
    }

private:
    std::vector<uint64_t> MDL_RawIndex_;
    std::vector<std::vector<uint64_t>> factValues_;
    std::vector<std::vector<uint64_t>> MDL_Index_;
    std::vector<std::vector<double>> MDL_RawScore_;
    std::vector<std::vector<double>> MDL_Score_;
    std::vector<uint64_t> MDL_Score_Length_;
    std::vector<double> bestScore_;
    int n_ = 0;
    int noRows_ = 0;
};

在主代码文件"example.cpp"上，当我尝试创建对象时，它会抛出错误。代码如下：当我尝试创建在上一个文件中声明的类 Computing 的对象时出现错误。在这种情况下，不会调用构造函数：

#include <iostream>
#include <vector>
#include "csv.hpp"
#include "mdl.hpp"
#include "Heuristic.hpp"
Computation bootup() {
    std::string in = "/Users/skx/Google Drive/Semester3_Fall15/CSE603/HeuristicSearchPy/child.csv";
    int noRows = 4000;
    std::vector<signed char> Data;
    int n = 20;
    if (!read_csv(in, n, noRows, Data)) {
        std::cout << "error: could not read input" << std::endl;
        return -1;
    }
    MDL mdl(n, noRows, Data);
    Computation h(n,noRows,mdl);   //This object creation is where error is occurring 
    return h;
    }

int main(int argc,char* argv[]) {

return 0;
}
