C ++根目录：IncrementalExecutor :: executeFunction：链接时[链接界面功能]无法解析符号'_ZStorSt13_Ios_OpenmodeS_'

问题描述

我是新C ++，正在Ubuntu 18.04中使用CERN ROOT解释器6.22 / 00（当然需要）。我正在尝试编写一个简单地从文件读取数据列并将数据写入输出文件的代码。这是我的代码的最低可复制版本，在这里我是从数组而不是从文件读取的：

# include <iostream>
# include <fstream>
//# include <math.h>
# include <iomanip>
//# include <cmath>
//# include <stdlib.h>
# include <cstdlib>
//# include <fstream.h>
//# include <string.h>
# include <string>
//# include <direct.h> 
//# include <dos.h> //For Sleep() 

using namespace std;
int main()
{
    char outputFileName[30] = "output.dat";
    int NumOfRows = 5;
    int nCount[5] = {0,1,2,3,4};
    int nCount2[5] = {1,4,5};
    
    cout<<"Creating output file"<<endl;
    ofstream outFile(outputFileName);
    outFile<<"1st Param"<<setw(15)<<"2nd Param"<<endl; //Header
        for (int a = 1; a < NumOfRows; a++){
            
            // Reading rest of file
            outFile << nCount[a] << nCount2[a];

                
        }
    outFile<<""<<endl;
    
            // Warning if file cant be opened
    if(!outFile.is_open()){ 
        cout << "Error opening file. \n";
        //cout << "Giving Retry... \n";
    }
    if(outFile.is_open()){
        cout<<"Output File was opened successfully"<<endl;
    }
    if(outFile.good()){
        cout<<"Output File is ready for reading"<<endl;
    }
    outFile.close();
    
    if(!outFile.is_open()){
        cout<<"Output File closed successfully"<<endl;
    }
    
    return 0;
}

但是，当我运行此代码时，出现错误：

IncrementalExecutor::executeFunction: symbol '_ZStorSt13_Ios_OpenmodeS_' unresolved while linking [cling interface function]!
You are probably missing the deFinition of std::operator|(std::_Ios_Openmode,std::_Ios_Openmode)
Maybe you need to load the corresponding shared library?
IncrementalExecutor::executeFunction: symbol '_ZSt4setwi' unresolved while linking [cling interface function]!
You are probably missing the deFinition of std::setw(int)
Maybe you need to load the corresponding shared library?

我尝试了错误建议，并为std::setw(int)查找了库，但是我saw在<iomanip>中定义了它，我已经将其包含在代码中。我在这里想念什么？
