Compiling with g++ - Error - Help

Hi,

I am trying to figure out why this code doesn't work when I compile it
under linux with g++

Following is the code, and the error message I get is:

main.cpp: In function =E2int main()=E2:
main.cpp:5: error: conversion from =E2Person*=E2 to non-scalar type
=E2Person=E2 requested

I used the following command to compile: g++ Person.h Person.cpp
main.cpp

------------------------------------
//filename: Person.h
class Person
{
        private:
                int age;
        public:
                void setAge(int age);
};

--------------------------------------
//filename: Person.cpp
#include "Person.h"

void Person::setAge(int age)
{
        this->age = age;
}

--------------------------------------
//filename: main.cpp
#include "Person.h"

int main()
{
        Person mark = new Person();
        mark.setAge(5);

        return 0;
}

----------------------------------------

I am not sure what the error means, but everything looks okay to me.
Looking forward to someone helping me out on this.

Thank you!

Ali
