Linking problems with Code::Blocks 13.12 (SFML version 2.4.1)

[airbournenation]

Hi,
whenever I try to compile any of the sample codes, the same type of error occurs. Here's the build log:

And the code:

#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;
}

SFML_STATIC is defined.


Linker/compiler dirs are defined correctly.


A few hours on Google yielded no results.

I use the MinGW version of SFML. Doesn't matter, whether it's 32/64 bit, either one produces the same errors.
My computer runs on Windows 7 SP1 64 bit.

[eXpl0it3r]

You're linking both release and debug SFML libraries against your code. Make sure to only link release libraries in release mode and debug libraries in debug mode.

One source of mistake may be, that you added SFML libraries in the project wide settings.

[airbournenation]

Thank you for your fast reply! Yes, I did the linking globally project-wise, as opposed to linking Debug and Release versions separately. Sadly, this did not change anything .

[eXpl0it3r]

Make sure to do a full rebuild after you removed the global settings. Also provide the full error and full build command.

Where can I find the build command?

You are still linking release and debug libraries.

If you can't find the settings, try to start a new project.

[airbournenation]

What? I double checked it to prevent things like that from happening! Seems like your suggestion is the only viable option in this mess.

[airbournenation]

So, I've tried to make a new project with the same settings but without the mistakes you've mentioned before. No luck.

[airbournenation]

What the f***, Code::Blocks? Why is it linking libraries from both Debug and Release?

[Laurent]

Copy-paste the content of your project file here (it's XML, easily readable) and we'll tell you what's wrong.

[eXpl0it3r]

You're not linking anything in your project. Are you certain that you didn't add the libraries to the global compiler settings?

[airbournenation]

Yes. I'm absolutely sure. Double check made me even more sure of myself .
