[SFML] Unable to run example project

shinatose

Hi, i've been trying the whole day to run the example project for SFML without success. Any help would be very nice. I'm thinking about buying a copy of spine but i would rather test its runtimes before.

I'm using Visual Studio 2013 and I can run basic SFML vanilla projects without problems, but if I try to run the example given with the runtimes, I get a long list of "error LNK2019: unresolved external symbol" errors during project link.

I'll briefly describe what I've done so far:

Created a new project in Visual Studio.
Added the example files to the project (main.cpp, spine-sfml.cpp, spine-sfml.h)
Added these include directories to the VS project: "spine-sfml\src"; "spine-c\include"; "SFML-2.1\include"
Added these library directories to the VS project: "SFML-2.1\Libs\Debug"
Added these SFML dependencies to the VS project: "sfml-graphics-d.lib"; "sfml-window-d.lib"; "sfml-system-d.lib"; "sfml-main-d.lib"; "sfml-audio-d.lib"
Copied SFML dll files into [Visual studio project folder]\Debug

And here's a copy paste of the whole Visual studio output:

I'm not very experienced with Visual Studio or even c++ in general, so I might have done some stupid newbie error, but please help me find and fix it 🙂

Looks like you are missing "spine-c\src" at this step.

Project setup with C/C++ is always pretty nasty!

Thanks for the reply!
Actually I did already try it, but then I saw that nothing changed and removed it, ahah.
Anyway now I included it again and yeah, I still get the same errors 🙁 any idea?

Nate

Unresolved external means it found the headers but not the object files. If you were building the spine-c source, it would find them. You probably only have them in your include path, put them in your source directory.

Thanks for the support, I finally got it right!
Indeed as you said, I didn't have them in my Source Files project folder. What a noob 😃

Nate

Congrats! Now promptly forget everything you did so you can enjoy the same pain the next time you set up a project. :wonder:
