SFML 2.0 Graphics linking error

So this is the chunk of code I am trying to compile. I have it all statically linked and I've defined so in VC++ 2010's properties or whatever. So all of that is correct. I have the latest version of 2.0 for VC++ 2010 installed on my computer. But yet, every time I still get this error.

Any ideas? Thank you very much for taking the time to read and possibly respond.

The fact that the error messages indicate that the linker is still looking for __declspec(dllimport) functions means that you didn't define SFML_STATIC properly.

Additionally it's not a good practice to use pragma comment for linker settings, because such setting do not hace anything to do with the code but are project settings and should be set in the project settings of VS.
If you'd follow the official tutorial you'd see this all as well. ;)

I'm not sure I understand? I never had this problem in SFML 1.6. How would I define SFML_STATIC?

Everything is explained in the tutorial. Check here for VS.

BTW, a lot of things have changed since 1.6. Before you had to define SFML_DYNAMIC to use dynamic libraries, now you do it for the static version.

Have not encountered this, but it looks like the version of SFML you're linking to has the std libs built-in, and your project is also set to link them in directly, which will result in duplicate definitions in the binary.

If you built the SFML libs from CMAKE, try unchecking the SFML_USE_STATIC_STD_LIBS option and building the library again. This will give you a set of sfml static libs that don't have the std libs included.

If you just downloaded SFML binaries from somewhere, try going to Linker -> Input -> Ignore Specific Default Libraries in your project settings and adding libcmtd;libcpmtd;msvcrtd to the list for debug and libcmt;libcpmt;msvcrt for release. This will tell the linker to not try linking in the stdlibs directly, as you're already linking to sfml libs that already have them.

Well you can link the runtime library statically in the library and the application you just have to make sure to use the right runtime library, that is /MTd or /MT which can be set in Project->Preferences->C++->Code Generator
