    Question No output written to a.out

    Hello,
    I really need to know why my program is not working at all. The entire error message says:
    Code:
    Undefined                       first referenced
     symbol                             in file
    Personal::Personal(std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> >, int, long)/var/tmp//cchaaWiZ.o
    ld: fatal: Symbol referencing errors. No output written to a.out
    collect2: ld returned 1 exit status
    Can anyone help me? Here is all of my code. I have been looking at it for hours trying to figure out what is wrong.


    Code:
    //Preprocessor Directives
    #include <iostream>
    #include <iomanip>
    #include <string>
    
    using namespace std;
    
    //Personal Class Declaration
    class Personal 
    	{
    	private:
    		string name;
    		string address;
    		int age;
    		long phone;
    		
    	public:
    		Personal();
    		Personal(string, string, int, long);
    
    		void setName(string);
    		void setAddress(string);
    		void setAge(int);
    		void setPhone(long);
    		string getName();
    		string getAddress();
    		int getAge();
    		long getPhone();
    	};
    
    //Class Implementation
    Personal::Personal()
    {
    	name = " ";
    	address = " ";
    	age = 0;
    	phone = 0;
    }
    //Set name function definition
    void Personal::setName(string pname)
    {
    	name = pname;
    }
    //Set address function definition
    void Personal::setAddress(string paddress)
    {
    	address = paddress;
    }
    //Set age function definition
    void Personal::setAge(int page)
    {
    	if(page < 0)
    	{
    		cout << "Invalid, age must be a positive integer." << endl;
    	}
    	else
    		age = page;
    }
    //Set phone function definition
    void Personal::setPhone(long pphone)
    {
    	phone = pphone;
    }
    //Get name function definition
    string Personal::getName()
    {
    	return name;
    }
    //Get address function definition
    string Personal::getAddress()
    {
    	return address;
    }
    //Get age function definition
    int Personal::getAge()
    {
    	return age;
    }
    //Get phone function definition
    long Personal::getPhone()
    {
    	return phone;
    }
    
    //Client Program
    int main()
    {
    	//Temp Variables

    	string personaladdress;
    	int personalage;

    	//Instantiate three Personal objects
    	Personal ashley("Ashley", "313 State St.", 21, 3209986);
    	
    	Personal alex("Alex", "705 4th St.", 24, 3402257);
    	
    	Personal input;

    }

    Personal(string, string, int, long);
    You have only declared, but not defined your second constructor.
