Hello all,

I recently downloaded and successfully built the latest version of SFML from github but when I try to run the example graphics program (from the tutorials) it fails with the following errors.

Code: [Select]

Can anyone help me?

(I'm using Visual Studio 10)

Have you linked SFML? If so, how?

Are you linking to static or dynamic libraries? And, sf::Window::GetEvent doesn't exist anymore. This must be an old version.

static i beleive.

I changed the code:

If you link statically, you must define SFML_STATIC.

Please tell us exactly what linker entries you have and which configuration (static or dynamic, release or debug). You have specified the configuration when creating the Visual Studio 2010 project with CMake.

Here are the libraries i link

Release type in cmake

You don't link a library at all. You just specify some directories, but the wrong ones -- there is the source code, not the binary .lib files.

After installing SFML (compiling the INSTALL project), choose the directory SFML/lib as library directory. Then link the libraries (i.e. enter them at Linker -> Input), where "xy" is a component like "graphics" or "system":

Dynamic Release: sfml-xy.lib
Dynamic Debug: sfml-xy-d.lib
Static Release: sfml-xy-s.lib
Static Debug: sfml-xy-s-d.lib
