These in your project-wide linker settings:

• glew
• freetype
• jpeg
• opengl32
• gdi32
• winmm

These in your debug build target settings:

• sfml-graphics-s-d
• sfml-window-s-d
• sfml-system-s-d

These in your release build target settings:

• sfml-graphics-s
• sfml-window-s
• sfml-system-s

Don't forget to change the linker policy of your targets to Prepend target options to project options, as I showed in the picture I posted.

Just did it, and finally, it worked!

Thanks a ton, by the way. I spent about two days trying to figure this out and now I feel dumb.

This is the linking order that I have:

Did I mess something up or is there a better way to link like this?

General / Re: AW: Undefined reference to blahblahblah in CodeBlocks

The order is wrong. I've personally not found a way to tell where the global libs should be added. As such you'll have to add all the global libs to debug and release instead.

I followed your instructions and put the libraries back where they should be but now I get a DLL error because apparently I'm missing OpenGL32. What do I do now?

General / [SOLVED]Undefined reference to blahblahblah in CodeBlocks

« on: April 16, 2015, 03:55:16 am »

There are several people out there with the same problem as me, but the solutions they were given were either unclear or didn't help me.
I am using Windows 7 x86, Code Blocks Release 12.11 rev 8629, and SFML 2.2 GCC 4.8.1 TDM (SJLJ) - 32-bit. I have followed the instructions of the tutorial as best as I could but I still get this in the build log:

I set the compiler and linker search directories to be global for both debug and release, and same for the dependencies that I used.

The settings for the debug and release are the same except for the -d suffix which is only for debug.

And I globally defined static under Compiler settings > #defines.

The code I wanted to compile is the same as the tutorial code.

(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;
}

Did I do anything wrong here? Is there something I didn't mention also?

SOLVED: Solution is here for anyone who has the same problem:

These in your project-wide linker settings:

• glew
• freetype
• jpeg
• opengl32
• gdi32
• winmm

These in your debug build target settings:

• sfml-graphics-s-d
• sfml-window-s-d
• sfml-system-s-d

These in your release build target settings:

• sfml-graphics-s
• sfml-window-s
• sfml-system-s

Don't forget to change the linker policy of your targets to Prepend target options to project options, as I showed in the picture I posted.
