Graphics / [SOLVED]Crash when using loadFromFile for a shader

« on: August 31, 2020, 12:55:22 pm »

I was trying to learn how shaders work and found out SFML supports them.. so i made a sample program:

sf::RenderWindow window(sf::VideoMode(1280, 720), "Shaders");
window.setVerticalSyncEnabled(true);
sf::CircleShape circle(30.5f);
circle.setPosition(300.f, 300.f);
circle.setFillColor(sf::Color::Green);
sf::Shader shader;
if(sf::Shader::isAvailable()){
        printf("Shaders available");
        if (!shader.loadFromFile("fragment_shader.frag",sf::Shader::Fragment))
        {
        }  
    }
while (window.isOpen()) {
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed) {
                window.close();
            }
        }  
        window.clear(sf::Color::Black);
        window.draw(circle, &shader);
        window.display();
    }
 

This program crashes every time i launch it, but if i change loadFromFile with loadFromMemory ( to wich i now pass the shader saved in a std::string) it works as expected. I have no idea what could cause this and i'm looking for solutions to try out

EDIT: I tried to run the example shader program that comes with sfml. It also crashes when i try to run. I have tried it before and that time it worked so i must have messed something ...

EDIT2: I found a temporary soultion by using loadFromStream() instead of loadFromFile(), minor inconvenience but works well for now.
