看如上报错的原因是什么？多谢

看如下报错的原因是什么？谢谢
代码如下：
头文件：vector.h

C/C++ code

#ifndef VECTOR_H#define VECTOR_Htemplate <typename object>class vector{    public:        explicit vector(int ini_size = 0);        vector(const vector &rhs);        ~vector();        const vector & operator= (const vector &rhs);        void size() const;        void resize(int new_size);        void reserve(int new_capacity);        object & operator[](int index);        const object & operator[](int index) const;        void push_back(const object & x);        enum{SPARE_CACPCITY = 16};    private:        int the_size;        int the_capacity;        object *objects;};#endif

vector.cpp文件

C/C++ code

#include "vector.h"vector::vector(int init_size):the_size(init_size),the_capacity(init_size + SPARE_CAPACITY){    the_size = init_size;    objects = new object[the_capacity];}vector::vector(vector & rhs):objects(NULL){    operator=(rhs);}~vector::vector(){    delete [] objects;}const vector::vector & operator=(const vector & rhs){    if(this != &rhs){        delete [] objects;        the_size = rhs.size();        the_capactity = rhs.the_capacity;        objects = object[the_capacity];        for (int i = 0; i < the_size; i++){            objects[i] = rhs[i];        }        return *this;    }}void size() const{    return the_size;}void resize(int new_size){    if(new_size > the_capacity){        the_size = new_size * 2 + 1;        reserve(the_size);    }    the_size = new_size;}void reserve(int new_capacity){    if(new_capacity < the_capacity){        return;    }    object * old_objects = objects;    objects = new object[new_capacity];    for(int i=0; i < old_objects.size(); i++){        objects[i] = old_objects[i];    }    the_capacity = new_capacity;    delete [] old_objects;}object & operator[](int index){    return objects[index];}void push_back(object & x){    if(the_size == the_capacity){        reserve(2 * the_capacity + 1);    }    objects[the_size++] = x;}

main.cpp文件

C/C++ code

#include "vector.h"#include <iostream>#include <string>using namespace std;int main(){    string str("abc");    vector<string> vc;    vc.push_back(str);    cout << vc[0] << endl;    return 0;}

三个文件在同一个目录
使用下面的命令编译 g++ main.cpp -o main

报错信息如下：
/tmp/cc93OlsO.o: In function `main':
main.cpp:(.text+0x66): undefined reference to `vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >::vector(int)'
main.cpp:(.text+0x79): undefined reference to `vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >::push_back(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

main.cpp:(.text+0xc8): undefined reference to `vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >::~vector()'
collect2: ld returned 1 exit status

请问
1、报错是什么意思
2.代码那里有问题导致报错？

------解决方案--------------------

模版类需要把实现也放到头文件里面. 而且你的实现也不对, 写成内联函数的方式吧.

另外，楼主，没事别搞些尽和标准库里东西重名的东西。
