I'm new to the SFML library. I'm trying to compile an example program.

I have got the following sample code from SFML official documentation:

#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>

int main()
{
    // Create the main window
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML window");
    // Load a sprite to display
    sf::Texture texture;
    if (!texture.loadFromFile("cute_image.jpg"))
        return EXIT_FAILURE;
    sf::Sprite sprite(texture);
    // Create a graphical text to display
    sf::Font font;
    if (!font.loadFromFile("arial.ttf"))
        return EXIT_FAILURE;
    sf::Text text("Hello SFML", font, 50);
    // Load a music to play
    sf::Music music;
    if (!music.openFromFile("nice_music.ogg"))
        return EXIT_FAILURE;
    // Play the music
    music.play();
    // Start the game loop
    while (window.isOpen())
    {
        // Process events
        sf::Event event;
        while (window.pollEvent(event))
        {
            // Close window: exit
            if (event.type == sf::Event::Closed)
                window.close();
        }
        // Clear screen
        window.clear();
        // Draw the sprite
        window.draw(sprite);
        // Draw the string
        window.draw(text);
        // Update the window
        window.display();
    }
    return EXIT_SUCCESS;
}

I tried to compile it with the following command:

g++.exe code.cpp -s -lsfml-main -lsfml-audio-s -lflac \
    -lvorbisenc -lvorbisfile -lvorbis -logg -lsfml-network-s \
    -lws2_32 -lsfml-graphics-s -lfreetype -lglew32 -ljpeg \
    -lsfml-window-s -lopengl32 -lgdi32 -lsfml-system-s -lwinmm \
    -lgdi32 -luser32 -lkernel32 -lcomctl32 -lmingw32 \
    -luser32 -lgdi32 -ldxguid -mwindows \
    -std=c++11  -o code.exe

But I got these linker errors (paths shortened):

collect2.exe: error: ld returned 1 exit status

I think it's due to improper order of static libraries in the compile command. What is the correct order for linking static SFML libraries?

  • _"I think its due to improper order of static libraries in the compile command."_ Are you sure there **are** any static libraries in your command? Those look like dynamic ones to me. In which case, they need to be specified after the source file that depends on them; see [Why does the order in which libraries are linked sometimes cause errors in GCC?](https://stackoverflow.com/questions/45135/why-does-the-order-in-which-libraries-are-linked-sometimes-cause-errors-in-gcc) – underscore_d Dec 14 '17 at 15:03
  • You didn't [read the doc](https://www.sfml-dev.org/faq.php#build-link-static), did you ? – Chnossos Dec 14 '17 at 15:03
  • yes, i read the docs but didn't get it useful – Abdullah Al Mahmud Dec 14 '17 at 15:09

Your library order is fine (just having a quick look at it). You just forgot to link OpenAL (under Windows this would be -lOpenAL32), which is something to notice since all the undefined references start with _imp__al. Once done, everything should link and run as expected.
