Eclipse中链接文件的错误

Question

我在eclipse中链接文件时遇到了很多麻烦。即使我将每个文件路径添加到Project中的Paths and Symbols设置，我仍然会收到未定义的引用错误。我还包括头文件。我有1个应用程序文件以及3个实现文件和2个头文件。

这是一个实现文件：

#include <iostream>
#include <fstream>
#include "complex2.h"
#include "complexType.h"
using namespace std;

complexDB::complexDB(int lineCount)
{
    length = lineCount;

    c = new complexType[lineCount];
    num_complex = 0;
}
void complexDB::set_Index(int i, const complexType& cT)
{

    c[i] = cT;
}
void complexDB::set_numComplex(int n)
{
    num_complex = n;
}

void complexDB::insert(const complexType& insertItem)
{

    if (num_complex < length)
    {

        int oldi = num_complex;

        c[oldi] = insertItem; // inserts item at the last index of array
        num_complex++;
    }

}
void complexDB::deletee(const complexType& deleteItem)
{

}
void complexDB::list()
{
    cout << "in list:" << endl;
    cout << length << "\t" << num_complex << endl;
    for (int i = 0; i < num_complex; i++)
    {
        cout << c[i];
    }
}
void complexDB::save()
{
    ofstream fout;
    fout.open("126complex.txt");
    if (fout.is_open())
    {
        cout << "is open" << endl;
    }
    for (int i = 0; i < num_complex; i++)
    {
        fout << c[i];
    }

}
complexDB::~complexDB()
{
    delete[] c;
}

这是另一个实现文件：

#include <fstream>
#include <sstream>
#include "complexType.h"
//#include "complex2.cpp"

using namespace std;
#define CA_MAX_SIZE 10
#define ComplexFileName "126.txt"

void CreateComplexFile()
{
    complexType ca[CA_MAX_SIZE];
    ofstream fout;
    fout.open(ComplexFileName);
    for (int i = 0; i < CA_MAX_SIZE; i++)
    {
        ca[i].setComplex(i, i + 1);
        fout << ca[i];
    }
    fout.close();
}

void ReadComplexFile()
{
    complexType ca[CA_MAX_SIZE];
    ifstream fin;
    fin.open(ComplexFileName);
    for (int i = CA_MAX_SIZE - 1; i >= 0; i--)
    {
        fin >> ca[i];
    }
    fin.close();
}

void ReadComplexFileEOF()
{
    complexType ca[CA_MAX_SIZE];
    ifstream fin;
    fin.open(ComplexFileName);
    int i = 0;
    while (!fin.eof())
    {
        fin >> ca[i++];
    }
    fin.close();
}

void ReadComplexFileTwice()
{
    complexType ca[CA_MAX_SIZE];
    ifstream fin;
    fin.open(ComplexFileName);
    for (int i = CA_MAX_SIZE - 1; i >= 0; i--)
    {
        fin >> ca[i];
    }
    fin.clear();
    fin.seekg(0, ios::beg);
    int i = 0;
    while (!fin.eof())
    {
        fin >> ca[i++];
    }
    fin.close();
}

void ImportComplexFile(string fname)

{
    ifstream fin;
    double real, im;
    char plusorminus, ichar;
    string oneline;
    fin.open(fname.c_str());
    while (!fin.eof())
    {
        getline(fin, oneline);
        stringstream(oneline) >> real >> plusorminus >> im >> ichar;
    }
    fin.close();
}

void ImportComplexFile2(string fname)
{
    ifstream fin;
    fin.open(fname.c_str());

    double real, im;
    char plusorminus, ichar;
    complexType c;
    string oneline;
    while (!fin.eof())
    {
        getline(fin, oneline);
        real = 0;
        im = 0;
        plusorminus = '\0';
        ichar = '\0';
        stringstream(oneline) >> real >> plusorminus >> im >> ichar;
        switch (plusorminus)
        {
            case '-':
                im = -im;
                break;
            case 'i':
                im = real;
                real = 0;
                break;
            case '\0':
                im = 0;
                break;
        }
        c.setComplex(real, im);
        cout << c << endl;
    }
    fin.close();
}

对于这两个文件，任何带有complexType的内容都会出错：

  

对complexType :: complexType（double，double）＆＃39;的未定义引用

同样对于主文件，我收到此错误：

  

找不到-lC：\ Users \ Altemush \ Documents \ SJSU_Dev \ projects_mingw \ complex2 \ src

我想我没有正确地将文件链接在一起，虽然我以为我做过了。拜托，任何人都可以帮助我吗？

这是complexType.h：

#ifndef H_complexNumber
#define H_complexNumber
#include <iostream>
using namespace std;

class complexType
{
    friend ostream& operator<< (ostream&, const complexType&);
    friend istream& operator>> (istream&, complexType&);

    friend complexType operator+(const complexType& one,
                                  const complexType& two);




public:
    void setComplex(const double& real, const double& imag);
    complexType(double real = 0, double imag = 0);

    complexType& operator=(const complexType &rhs);

    complexType operator-(const complexType& two);
    complexType operator-(int x);


    int realPart;
    int imaginaryPart;
};

#endif

这是complexType.cpp：

#include <iostream>
#include "complexType.h"

using namespace std;

ostream& operator<< (ostream& os, const complexType& complex)
{
    os << "(" << complex.realPart << ", "
       << complex.imaginaryPart << ")" << endl;
    return os;
}

istream& operator>> (istream& is, complexType& complex)
{
    char ch;
   // is >> ch;
    is >> complex.realPart;
    is >> ch;
    is >> complex.imaginaryPart;
    is >> ch;
    return is;
}



complexType::complexType(double real, double imag)
{
    setComplex(real, imag);
}

void complexType::setComplex(const double& real, const double& imag)
{
    realPart = real;
    imaginaryPart = imag;
}


complexType operator+(const complexType& one, const complexType& two)
{
    complexType temp;

    temp.realPart = one.realPart + two.realPart;
    temp.imaginaryPart = one.imaginaryPart + two.imaginaryPart;

    return temp;
}

complexType complexType::operator-( const complexType &operand2 )
{
   return complexType( realPart - operand2.realPart,
      imaginaryPart - operand2.imaginaryPart );
}

complexType complexType::operator-( int operand2 )
{
   return complexType( realPart - operand2,
      imaginaryPart - operand2 );
}
complexType& complexType::operator=(const complexType &rhs){

    realPart = rhs.realPart;
    imaginaryPart = rhs.imaginaryPart;

    return *this;
}
