Entry point must be defined

[TheDianamu]

Hi, I'm having troubles setting up:

I get  LINK : fatal error LNK1561: entry point must be defined with this code

#include "LEngine.h"
#include <SFML\Graphics.hpp>

void LEngine::Sprites(){
        sf::Texture t_grass;
        sf::Texture t_stone;
        sf::Texture t_water;

        t_grass.loadFromFile("grass.png");
        t_stone.loadFromFile("stone.png");
        t_water.loadFromFile("water.png");

        sf::Sprite grass;
        sf::Sprite stone;
        sf::Sprite water;

        grass.setTexture(t_grass);
        stone.setTexture(t_stone);
        water.setTexture(t_water);
}

void LEngine::Map(){
}

bool LEngine::Init(){
        window = new sf::RenderWindow(sf::VideoMode(800, 600, 32), "RPG");

        if(!window)
                return false;

        return true;
}

void LEngine::Events(){
        sf::Event evt;
        //Loop through all window events
        while(window->pollEvent(evt)){
                if(evt.type == sf::Event::Closed)
                        window->close();
        }
}

void LEngine::MainLoop(){
        while(window->isOpen()){
                Sprites();
                Map();
        }
}

void LEngine::boot(){
        if(!Init())
                throw "Could not initialize Engine";

        MainLoop();
}

I've tried google, I've try almost everything, but I cannot get it work.

[zsbzsb]

Where is you int main() { }?

I've tried google, I've try almost everything, but I cannot get it work.

How is this possible, when searching for the error message yields tons of useful results?

[TheDianamu]

Where is you int main() { }?

Opps, I forgot to make that xD

[TheDianamu]

Also what does

First-chance exception at 0x103159da (msvcr100d.dll) in Game.exe: 0xC0000005: Access violation reading location 0xccccccc0.
Unhandled exception at 0x103159da (msvcr100d.dll) in Game.exe: 0xC0000005: Access violation reading location 0xccccccc0.
 

mean? Using the same code as before

[Nexus]

Step through the code with the debugger and find out where it crashes.

By the way, LEngine::Sprites() is completely meaningless. Take a look at the variable scopes...

window = new sf::RenderWindow(sf::VideoMode(800, 600, 32), "RPG");

    if(!window)
        return false;

    return true;

This code is questionable, too. First, you should never use new with raw pointers. Use automatic variables (sf::RenderWindow instead of sf::RenderWindow*), or -- if really necessary -- smart pointers. Second, the new operator does never return a null pointer. Third, the statement could be simplified to return window; or return window != nullptr (but as mentioned, it's useless anyway).

I have sf::RenderWindow* window; in the header file.

It also stops the startup at : 'Game.exe': Loaded 'C:\WINDOWS\system32\imagehlp.dll', Cannot find or open the PDB file

[Nexus]

I have sf::RenderWindow* window; in the header file.

That's what I mean: Just use

sf::RenderWindow window;

Or do you want to reduce compile-time dependencies (Pimpl idiom)?

What do you mean by "reduce compile-time dependencies"?

[Nexus]

Apparently header dependencies are not your concern, so it's fine to use

sf::RenderWindow window;

instead of

sf::RenderWindow* window;

If you're interested in what I meant (it's not relevant for your problem), just search for the Pimpl idiom I mentioned before.

[TheDianamu]

Still doesn't help with the error on why it crashes

[TheDianamu]

Anybody?

[zsbzsb]

No need to bump your thread, learn to have patience. 

One thing that sometimes causes these types of issues is when your mixing debug and release modes. And while your at it post a complete and minimal example that crashes.
