[Solved] Undefined reference [Static Linking]

[Mokka]

I fixed it, look down below for my working linking order....


---------------
Hey there

I am using SFML for quite a while now, but just used dynamic linking.

Now I decided to set up static linking.

But every time I try to compile something, I get a few errors...

I think I did set up the project properly...

(click to show/hide)

I also added the "SFML_STATIC" to the #defines...

The code is:

(click to show/hide)

#include <SFML/Graphics.hpp>

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

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

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

    return 0;
}
 

That's the error message:

I hope that somebody can help me.

Thanks in advance

Maybe it's just me (on my phone right now), but the image of the error message is too small and blurred for me to read anything... Have you considered posting the text of the message instead?

Anyway, a "undefined reference" error is a linker error and basically means that there is a symbol referenced in your code that the linker couldn't resolve (find). This usually means that there's a library you forgot to link or you linked the libraries in the wrong order.
Are you sure you are linking all sfml's dependencies explicitly (needed when doing static linking)?

Read the official SFML 2.2 tutorial and I mean read it. Because the static linking has changed for SFML 2.2 and you now need to link against SFML's dependencies as well.

Yeah that's a phone issue...

If i'm not mistaken he does indeed link against SFML's dependencies
To me it looks like he declared the libs in a wrong order.

So how is the right linking order. ^^

Thanks for your replies though

Look at the tutorial, the way it's listed there is an order that works.

It usually is if x depends on y then x comes before y.

I understood it. I now moved all the main module (sfml-system-s(-d) and so on) and let the dependencies stay at the top. It changed like nothing...

But I recognised that in the error log there is a file that is located on my D:\\ drive:

D:\sfml-release\_Sources\SFML\src\SFML\System\Win32\SleepImpl.cpp

But I didn't find the folder/directory. The dir "D:\sfml-release\" is not existent on my PC?!

Is that supposed to happen or am I missing some files?!


Also: Which order it's listed??
The table that lists the needed dependencies?! Because otherwise there is just the dynamic linking shown-

Thanks for the reply ^^

[Mokka]

Ok....
I moved all the modules to the top...
So sfml-system-s and co. to the top of the list and then the dependencies...

This got rid of the

error, but instead I now have an

error...
I'm completely stuck now

[Mokka]

Got it to work....

I had the dependencies setted wrong.

If anyone should have problems with it, here is a picture of the finished order.
Note: I used the "extlib" included on the github directory.....

Thank you all so much for helping. It is working perfectly for me now
