Problem with program crashing as soon as activated

[Frostbite]

I am using MinGW as far as I know (I'm actually not too knowledgeable on that) And the problem is that whenever I compile and run the program crashes immediately, the window does pop up, but shows nothing. The first ten times this happened it slowed down my computer considerably, now it just shows up as a regular non-responsive program.

Here are my build messages and build log, I think they have the reason for the problem. Ask if you need any other information.

Thank you again. The sfml forums are some of the best when it comes to help and support. I am really appreciative ahead of time.



------Edit--------
Oh and I just realized it would be a good idea to mention this,  I have other SFML games that compile and run just fine on my computer. They use the same .dll's and the same linker and compiler. I guess this means the problem must be in the code somewhere. I just have no clue where.

Can you show your code? Have you tried the samples provided in the SDK?

Here are my build messages and build log, I think they have the reason for the problem

No, this is not related. It's because you forgot to define SFML_DYNAMIC (it is explained in the "getting started" tutorial).

Here are all the parts pertaining to SFML, as far as I can tell at least,

I apologize for putting it all in there, I just don't know another way to do it.

Also, no I haven't looked at the Code::Blocks page, it really didn't occur to me. THough I don't know what I would be looking for.

[Frostbite]

I just compiled it again and its doing something completely different... It shows me the white dots that are placeholders for images, and the buttons don't work, but it isn't crashing. And the above two problems I could probably fix myself.

Its really strange. But I don't really think there is a problem anymore.


----edit----
And once again its crashing, but everything loads, so its probably ok

[Laurent]

Have you tried not creating your SFML window before main() is executed? Global objects can be dangerous, especially if they use a constructor that does something.

Also, no I haven't looked at the Code::Blocks page, it really didn't occur to me. THough I don't know what I would be looking for.

To make sure that you properly setup your compiler and environment -- which you didn't (but that doesn't explain your problem)

[Frostbite]

Can I do that? Don't I need to declare it before I can use it in all of my functions?

Thanks for you patience... I can't help but feel really feel ignorant right now,

[Laurent]

Can I do that? Don't I need to declare it before I can use it in all of my functions?

You can declare it globally (although globals are bad -- but you'll learn how to avoid them), but you can just declare it empty and create it in main().

Code: [Select]

sf::RenderWindow Window;
...

int main()
{
    Window.Create(sf::VideoMode(650, 400, 32), "Avian");
    ...
}

[Frostbite]

Alright, I did that. and thanks, I actually had been wondering about that.
It still crashes, but I think im going to work on it more tomorrow, its twelve thirty at night here and I have to get up at six tomorrow. Thank you for your help. And if I can't solve it by this time on Wednesday I'll head back here.

Again, thanks a lot, its really great to have some help =)

[Laurent]

If it still crashes, you can try removing every line of code that is not connected to the problem, and show me a minimal example that reproduces the problem.

[Frostbite]

ok, here we go, it still says not responding. Here is the condensed code I've compiled.

Code: [Select]


#include <SFML/Graphics.hpp>
using namespace std;

//------------------------------SF stuff------------------------------------------
    sf::RenderWindow Window;
//--------------------------End SF stuff------------------------------------------



int main(){
    Window.Create(sf::VideoMode(500, 300, 32), "Avian");
    int BattleOn = 4;
    while (BattleOn){

        }
}


It still crashed with a Window.Display()



-------------------edit---------------------------

and now its just my luck code::blocks is bugging out on me, I ran the exacutable in the snake game and took a look at the source code just before....
Now it gives me a window from mingw saying there is no disk in drive D, about a thousand times, or it says it uses an invalid compiler =(

[Laurent]

The event loop is missing. Without it, the window cannot handle its events and is kind of stuck (the exact effect depends on the OS).
