How to run SFML in CLion, Error undefined reference to?


I'm new to C++ and try to learn game programming, I choose SFML and run on CLion by Jetbrain and using Ubuntu machine. I following this tutorial SFML and Linux here my code :

#include <SFML/Graphics.hpp>

using namespace sf;

int main() {

RenderWindow window(sf::VideoMode(200, 200), "SFML Work!");
CircleShape shape(100.f);
shape.setFillColor(Color::Green);

while (window.isOpen()) {
    Event event;
    while (window.pollEvent(event)) {
        if (event.type == Event::Closed) {
            window.close();
        }
    }

    window.clear();
    window.draw(shape);
    window.display();
}

return 0;
}

When I run on CLion it error

CMakeFiles/SFMLBasic.dir/main.cpp.o: In function `main': 
undefined reference to `sf::String::String(char const*, std::locale const&)'
undefined reference to `sf::VideoMode::VideoMode(unsigned int, unsigned int, unsigned int)'
undefined reference to `sf::RenderWindow::RenderWindow(sf::VideoMode, sf::String const&, unsigned int, sf::ContextSettings const&)'
...
undefined reference to `sf::Shape::~Shape()'

How I config or setup to run SFML in CLion, I don't know CMAKE can do that? I only run by terminal, It work if I run this command.

g++ -c main.cpp
g++ main.o -o sfml-app -lsfml-graphics -lsfml-window -lsfml-system
./sfml-app

How to config to use all reference variable without do manual every time in Terminal? Thanks.


Solution

  • You need to link SFML library in your CMakeLists.txt.

    Have a look at CMake target_link_libraries.

    And this link may be helpful for you to know how to find SFML library path in CMake.

    Here is a FindSFML.cmake module: https://github.com/LaurentGomila/SFML/blob/master/cmake/Modules/FindSFML.cmake
