« on: November 03, 2023, 08:27:26 am »
I installed sfml in code bloks and tryed to run the program in the tutorial, it gives me a bounch of errors at compilation :

this is the program :
#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;
}

Are you trying to link SFML statically, but haven't set SFML_STATIC?

Can you provide your verbose build output: https://www.sfml-dev.org/faq.php#tr-grl-verbose-ide

You're trying to link Visual Studio library files (*.lib) while using GCC/MinGW. This won't work.

You have to use the MinGW package, and make sure your compiler aligns with the version linked on the SFML download page. It has to be 100% identical!

Alternatively, you can also use the SFML CMake Template, which automatically builds SFML, but you'd be using CMake.

I linked libraries as stated in the tutorial (lib prefix and .a extensions omited) and this is what i got :

-------------- Build: Debug in sfml (compiler: GNU GCC Compiler)---------------

g++.exe -LC:\Users\asus\Documents\SFML\SFML-2.6.1\lib -o bin\Debug\sfml.exe obj\Debug\lucru.o   C:\Users\asus\Documents\SFML\SFML-2.6.1\lib\sfml-graphics C:\Users\asus\Documents\SFML\SFML-2.6.1\lib\sfml-window C:\Users\asus\Documents\SFML\SFML-2.6.1\lib\sfml-system

You're not actually linking the libraries, you're just listing them. You need to specify the -l (lower case L) followed by the library you want to link. And since you specify the library path with -L already, you can also drop the path, the prefix and suffix.

-lsfml-graphics -lsfml-window -lsfml-system

If you use Code::Blocks, see the tutorial on where to specify the libraries: https://www.sfml-dev.org/tutorials/2.6/start-cb.php
