link error undefined reference to vector<String>

[dany2704]

I have compiled the dependent files of my source file mycpp.c and linked the files in the order which they have used .All the dependant files are available in the same folder.
**//Compilation**
$ g++ -c -w -Wno-deprecated String.c Vector.c DPStream.c CJ_Base.c mycpp.c
**//Linking**
$ g++ -g -o myexe String.o Vector.o DPStream.o CJ_Base.o mycpp.o
Vector.h
#include <iostream.h>
#include <fstream.h>
#include <iomanip.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>

#include "String.h"
#include "Storage.h"


template <class Object>
class Vector : public Storage{

public:
// ctors & dtor
Vector ();
Vector (int);
~Vector();

// overloaded operators
Object& operator[] (int nSubscript);
void operator<<(Object &);
void operator<<(char *);

// access methods
int Count(){return _iCurrElem;};
int Print(ofstream &);
void Flush();
Resize(int);

int IsType() {return VectorType;};

private:
long _iCurrElem;
Object *moj;
long _iUpperBound;

void _reserve(int);
};
#endif


Vector.c


#include"Vector.h"

template <class Object>
Vector<Object>::Vector ()
{
moj = new Object[3];
}

template <class Object>
Vector<Object>::Vector (int e)
{
moj = new Object[e];
}

template <class Object>
Vector<Object>::~Vector ()
{
delete[] moj;
}

template <class Object>
Vector<Object>::operator<<(Object &)
{
//stmt
}

template <class Object>
Vector<Object>::operator<<(char* ch)
{
//stmt
}

template <class Object>
Vector<Object>::Print(ofstream &foutput)
{
//stmt
}
Included the header files in the below order in mycpp.h

#include <iostream.h>
#include <fstream.h>
#include <iomanip.h>
#include <cstdio>
#include <cstdlib>
#include <cmath>
#include "String.h"
#include "Vector.h"
#include "DPStream.h"
#include "CJ_Base.h"

g++ compiler throws an error

Could you please help me to resolve the issue
Thanks for looking into this

Template classes have to be defined completely in the header.

How old is your compiler?

#include <iostream.h>
#include <fstream.h>
#include <iomanip.h> 

That's pre-1998 C++.
