/usr/bin/ld: cannot find -lsfml-system

[Kreshdev]

Greetings!

I am new to this site and I have followed many tutorials and searched before posting this to make sure that it wasn't already explained anywhere and it seems like it doesn't (or I just really suck at searching).
My problem is that when I try to compile a really simple script:

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
    // Create the main window
    sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window");

    // Load a sprite to display
    sf::Image Image;
    if (!Image.LoadFromFile("cb.bmp"))
        return EXIT_FAILURE;
    sf::Sprite Sprite(Image);

// Start the game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
        }

        // Clear screen
        App.Clear();

        // Draw the sprite
        App.Draw(Sprite);

        // Update the window
        App.Display();
    }

    return EXIT_SUCCESS;
}
, I am getting the following errors:

I have followed this tutorial for the static version and I did everything as told in there. Could anyone please help me out as I feel like this is a really stupid error and I have been looking for a way to fix this issue for a few hours now and I am tired of searching... : /

It seems you didn't install the release shared version of SFML (ld||cannot find -lsfml-system) and the release static version (ld||cannot find -lsfml-system-s).

Moreover, it seems you are linking your project against BOTH of them; which is wrong. You should only link your project against one type of libraries.

On a side note it's recommended to use shared libraries instead of static libraries on Unix-like OSes. There are plenty of discussion about that on the Internet if you want to know why and how.

Hi!

You seem to be on Linux, am I right?

If so, you don't the "-lsfml-xyz" options, it's only for Windows, but you should link the libraries instead, in this order:

Code: [Select]

/usr/local/lib/libsfml-network.so
/usr/local/lib/libsfml-audio.so
/usr/local/lib/libsfml-graphics.so
/usr/local/lib/libsfml-window.so
/usr/local/lib/libsfml-system.so

[Hiura]

If so, you don't the "-lsfml-xyz" options, it's only for Windows

Nope, you're wrong.  :wink: g++crash course

[Kreshdev]

Yes, I am on Ubuntu. Could anyone please tell me exactly what to do because I am a bit confused.  >.<

[Laurent]

Install SFML to a standard path (/usr/lib or /usr/local/lib for example), don't use the static libraries (-s), and everything should be ok.

[Kreshdev]

Alright, thank you. I will try that out and give you some news soon.

Ok, thanks for the clarification.

What I meant is, the "-lsfml-xyz" directives are just ingored here. They just don't work for me, I had to set the libraries as I've listed them above.

So, Kreshdev, what I suggest is, if you're on Code::Blocks, delete the "-lsfml-*" stuff and set Project/ Build options/ Linker settings/ Link libraries to:

Code: [Select]

/usr/local/lib/libsfml-network.so
/usr/local/lib/libsfml-audio.so
/usr/local/lib/libsfml-graphics.so
/usr/local/lib/libsfml-window.so
/usr/local/lib/libsfml-system.so

These files are at "/usr/local/lib", at least, for me. You should check where these files are on your computer. They also might be at "/usr/lib", for example.

[Kreshdev]

Is it normal if the library files are named, for example:
lsfml-audio.so.1.6
lsfml-etc.so.1.6 or should I rename them to have the .so extension only?
Because it keeps saying

Code: [Select]

/home/tristan/Code::Blocks/SFML/SFML/main.cpp|1|fatal error: SFML/Graphics.hpp: No such file or directory|

You must rather add /usr/local/lib to your linker search paths (see ldconfig).

Is it normal if the library files are named, for example:
lsfml-audio.so.1.6
lsfml-etc.so.1.6 or should I rename them to have the .so extension only?

Yes, there are also symbolic links:
sfml-audio.so -> sfml-audio.so.1.6
etc.

/home/tristan/Code::Blocks/SFML/SFML/main.cpp|1|fatal error: SFML/Graphics.hpp: No such file or directory|

This has nothing to do with the libraries, it's your compiler that can't find the headers.

[Kreshdev]

I am still experiencing the "'SFML/Graphics.hpp' no such file or directory" issue.. any idea how to fix it?

[Laurent]

Add the directory that contains the SFML headers to your compiler search paths.
