class sf::RenderWindow' has no member named 'clear'

Question

I've spent at least 5 hours trying to get the sfml library to work with my QT-creator ide. I have followed this tutorial https://github.com/LaurentGomila/SFML/wiki/Tutorial%3A-Compile-and-Link-SFML-with-Qt-Creator but still no luck. I continuously get the error that members of classes don't exist after building simple code. I can make instances of the classes, but I get multiple errors when trying to use members of the objects created. I have tried looking up library related issues, sfml issues, but I don't think I'm looking for the correct problem. This works and displays a window that will never close until forcing the program to quit: ``` #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 (true)//window.isOpen()) { sf::Event event; /*while (window.pollEvent(event)) { if (event.type == sf::Event::Closed) window.close(); }*/ //window.clear(); //window…

Accepted Answer

Not 100% sure, but since you're on Ubuntu it's very likely that instead of compiling SFML yourself, you just called `apt-get install sfml-dev` which in turn will install SFML 1.6 and not SFML 2.x. In SFML 1.6 the naming convention was CamelCase and was changed for SFML 2.0 to camelCase.

Since you want and should use SFML 2.x, you need to either use the unofficial package from the SFML forum or simply compile SFML yourself.
