Errors in Linking Files in Eclipse - c++

Question

I am having so much trouble with linking files in eclipse. I keep getting undefined reference errors, even though I added each file path to the Paths and Symbols setting in Project. I also included the header files. I have 1 Application file along with 3 implementation files and 2 header files.
Here is 1 implementation file:
#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;
}
Here is another implementation file:
#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();
}
For both files, anything with complexType gives the error:
undefined reference to `complexType::complexType(double, double)'
Also for the main file I get this error:
cannot find -lC:\Users\Altemush\Documents\SJSU_Dev\projects_mingw\complex2\src
I suppose I'm not linking the files together correctly, een though I thought I did. Please, can anyone help me?
Here is complexType.h:
#ifndef H_complexNumber
#define H_complexNumber

#endif
Here is complexType.cpp:

return is;
}

}
complexType operator+(const complexType& one, const complexType& two)

return temp;
}
complexType complexType::operator-( const complexType &operand2 )
