Question

I have installed this http://www.sfml-dev.org/index.php library on my Ubuntu system. The files are stored in /usr/local/include.

My Eclipse DOES include these files under “Includes >> GNU C++” but if I build the program, the compiler complains about undefined references.

#include <SFML/System.hpp>
#include <iostream>

int main()
{
  sf::Clock Clock;
  return 0;
}

Causes:

undefined reference to `sf::Clock::Clock()' main.cpp

Any guess what I missed to do?

Answer 1

I was right in my first suggestion.

Here documented, that you must compile like:

g++ -c clock.cpp
g++ -o clock clock.o -lsfml-system

So please add -lsfml-system to libraries.
