C++ :: Unable To Get Random Numbers Using Boost In A Class

I have been working with and trying to understand Boost for random number generating. I've come to understand that what I want is now in the C++11 standard, but I've stuck with Boost.

What I have done is create a simple main.cpp that generated random numbers successfully. From there I wanted to create a more optimal system by separating out the random code portion to a class that can be instantiated and called on demand. My problem now is that when I call the random routine of the class I just get one number no matter how many times it's called.

I know that rapid seeding is an issue so I put the seed function of the random portion in the class's constructer so that it is only called once on the creation of a class. I also tried making it a static member, but I haven't had success with that yet either. For now though, I would simply like to get successive random values upon calling the class's random function.

class header Code: #ifndef roomGen_hpp_
#define roomGen_hpp_
#include"boost/random.hpp"
#include"main.hpp"
class
roomGen
{
private:
boost::mt19937rngDimensions;

[code].....

The main.hpp file only contains a couple of struct definitions. In main I call the class with Code: randomRooms.push_back(randRooms.createRoom()); to get back a struct with random values and push it into a vector.

I'm unsure what I'm doing wrong here to only get back a single non random number from successive calls. I have tried moving the variable creation lines from roomGen::createRoom() to the private area of the class definition, but that causes me to get a slew of undefined errors so I had to settle on putting those declarations inside the function.
