Errors when trying to debug the code (SFML)

[BrianMatrix]

Hello!

I'm currently just trying C++ with SFML, and yeah

So I've installe SFML 2.0 for Visual C++ 2010 Express 64 bit, and I get an error while trying to run the debug of my code.

//Libraries
#include <SFML/Graphics.hpp>
#include <iostream>

int main()
{
	sf::RenderWindow window(sf::VideoMode(1280, 720),"SFML Game1");

	return 0;
}

And this is the result I'm getting when trying to run it

1>------ Build started: Project: Game1, Configuration: Debug Win32 ------

When changing "Enable Incremental Linking" to "Yes (/INCREMENTAL)"

I get this error

1 2 3

1

1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Any ideas on what I can do? :S

For the first set of errors, you need to link to the .lib file.

Go in your project settings, in the linker section -- under "input", add:

sfml-graphics-d.lib
sfml-window-d.lib

For Release build, you'll need to add the same ones, but remove the -d

sfml-graphics.lib
sfml-window.lib

For the second error... it looks like a file got corrupted. Just do a clean and rebuild.

I did link everything of that before I started this code.

I first tried with SFML 2.1, but it didn't work
then I degraded from 2.1 to 2.0, made a new project, did everything again, linking and that,

Still gets the same error..

I don't know what to tell you... you must not be linking properly, because that's the only thing that could cause those errors.

Instead of doing the link in the project settings, you can do it right in the cpp file with a pragma directive:

#pragma comment(lib,"sfml-graphics-d.lib")
#pragma comment(lib,"sfml-window-d.lib") 

Or... you can do what I do and just make a separate sfml.h header file that includes all the normal SFML headers and has pragmas to link to all the libs. That way I never have to deal with this link stuff.

Note I prefer the static libs to the dyanmic libs on windows:

#define SFMLFULL_INCLUDED

#define SFML_STATIC
