Title: Problem to get started with SFML
Post by: Challenger on June 29, 2013, 01:09:16 pm

Hey guys,

I'm just trying to get started with SFML by using MinGW.
I have SFML 2.0 and MinGW 4.7.2 .
I'm using Code Blocks and I have the dw2 version of MinGW.
So, I've obeyed this tutorial (http://sfml-dev.org/tutorials/2.0/start-cb.php) and thought, I've done well, but when I try to run the example code in the tutorial, I get a "Segmentation fault" error.

Code: [Select]

Program received signal SIGSEGV, Segmentation fault.
In std::basic_string<unsigned int, std::char_traits<unsigned int>, std::allocator<unsigned int> >::capacity (this=0x6fcc8d40) at d:/programmes/mingw32-4.7/bin/../lib/gcc/mingw32/4.7.2/include/c++/bits/basic_string.h:774 ()
So, why do the code not run?

regards Challenger :)

Windows.^^

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

It's an example code from the tutorial I linked. ;)

I can't find something else to come up to my mind..
I rarely find segmentation errors..:/
Maybe expl0it3r or Laurent can help out..
PS:: You tried to re-install MinGW?

Yeah, tried to reinstall MinGW.
No success. :(

If you're really running MinGW 4.7.2, then I think you'll have to recompile SFML, since the official version support the official MinGW 4.7 branch and the 4.7 TDM versions.

But since it's an error with strings, it might as well be, that you're mixing Debug and Release modes. When you're in debug mode, you'll have to link the debug libraries (with -d suffix) and in release mode the release libraries (without suffix). ;)

Hm, -d for debug and none for release, exactly what I've done. :(

Then you have to recompile SFML I guess. ;)
