c++ - Linker error with SFML -

i series of errors when running g++ -lsfml-window -lsfml-graphics -lsfml-system main.cpp on example sfml code, when running ubuntu, sfml 2.2 , g++ 4.8.2. i've tried reinstalling sfml package manager (libsfml-dev) , nothing works.

example sfml code:

#include <sfml/graphics.hpp> #include <string>  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; } 

error message:

there 2 ways solve issue. first swap of options command goes this: g++ main.cpp -lsfml-window -lsfml-graphics -lsfml-system. second option try updating g++ version 4.9.2, can achieved on ubuntu by doing this
