Problem Hello World !!!
I started studying SFML and came across a problem.
I can't build a tutorial project
When I execute a command
g ++ main.cpp --std = c ++ 17 -lsfml-graphics -lsfml-window -lsfml-system
I receive
main.cpp : (. text + 0x124): undefined link «sf :: WindowBase :: pollEvent (sf :: Event &)»
What is the problem?
Help
My tools
g ++ (Ubuntu 9.4.0-1ubuntu1 ~ 20.04.1) 9.4.0
clang ++ version 10.0.0-4ubuntu1
cmake version 3.16.3
