I can't get my program working

[DirtyBlasion]

So I tryed to make a global class of renderwindow and manage it from a function. I want to make functions separate, later I will do a multy window system, that can be helpful.(I use c++, sfml and glew)

So firstly I initialized it global.

Code: [Select]

sf::RenderWindow *window;

Code: [Select]

     void Init()
    {

        int Width = 640, Height = 480;
        sf::ContextSettings settings;
        settings.depthBits = 24;
        settings.stencilBits = 8;
        settings.majorVersion = 3;
        settings.minorVersion = 3;
        settings.attributeFlags = sf::ContextSettings::Core;
        window = new sf::RenderWindow(sf::VideoMode(Width, Height), "DirtyCraft", sf::Style::Titlebar | sf::Style::Close, settings);
        window->setVerticalSyncEnabled(true);
        //window.setFramerateLimit(60);

        if(GLEW_OK != glewInit())
        {
            std::cout << "Failed to run Glew";
            window->close();
        }
    }
and I try to manage it from this. my main problem is:

Code: [Select]

window = new sf::RenderWindow(sf::VideoMode(Width, Height), "DirtyCraft", sf::Style::Titlebar | sf::Style::Close, settings);I want a fast reply, because I need to start my project faster, because I need to finish it in like 3 months.

what's the problem ?

do you get an error at run time or compile time 

does the program run at all

does it compile at all

are you on windows, linux or mac

what version of sfml ?
which compiler ?

[DirtyBlasion]

I get some weird compiler errors. I use MinGW as compiler. And all the block me is, how I give it the value of a constructor. And I thinked to create a temp class with new... but it didn't. And I dont know how I can make that = work without any compiler errors

[Laurent]

Please read this carefully, and in your next post give us relevant details, like... the compiler errors

[DirtyBlasion]

Code: [Select]

window = new sf::RenderWindow(sf::VideoMode(Width, Height), "DirtyCraft", sf::Style::Titlebar | sf::Style::Close, settings); so this line is with problems for me!

Code: [Select]

these are the errors! So 24 is

Code: [Select]

window = new sf::RenderWindow(sf::VideoMode(Width, Height), "DirtyCraft", sf::Style::Titlebar | sf::Style::Close, settings);  and the rest are functions of the class, reffered by ->.

but if I put * to RenderWindow

Code: [Select]

        window = new sf::RenderWindow*(sf::VideoMode(Width, Height), "DirtyCraft", sf::Style::Titlebar | sf::Style::Close, settings);
I get less errors

Code: [Select]

the interesting fact is that all the errors are now on 24 who is window = new...

If this is not enought to solve the problem, tell me, what is missing and I will give it

[Laurent]

"undefined reference" errors mean that your code compiled fine, but that the linker failed to find some functions referenced in your code. These functions are SFML functions, which means that you didn't link SFML libraries correctly (ie. as explained in the tutorial) in your project settings.

If you write crap instead of correct code, yes you get other errors, from the compiler this time, but that's actually worse than before, even if the output is smaller

[DirtyBlasion]

The problem is they are linked... because it worked befor cut it in more functions, and make it pointer... it worked perfect

so i did like this

Code: [Select]

window = &(sf::RenderWindow(sf::VideoMode(Width, Height), "DirtyCraft", sf::Style::Titlebar | sf::Style::Close, settings));and the errors have simplified a lot!

Solved.... code blocks.... I dont understand why it forget the links... Thank you! Have a nice day
but, still how I can solve this??

[Laurent]

the errors have simplified a lot!

No... You write random stuff so the compiler no longer understands your code, and breaks after a single fatal error. Again, it doesn't mean that things are better. Stop writing random stuff and try to understand what's going on.

The problem is they are linked...

Not correctly, according to the linker errors.

[DirtyBlasion]

Solved. I was so confused... I knowed I linked them... but I don't understand why codeblocks forget the links. Thank you all, have a nice day/night!
