Did you link to libsfml-graphics.a?

How, i will do that? Any tutorial about those things?

Well, if you use a library you're supposed to know (or learn) how to do it, this has to do with your EDI/compiler, not with SFML

But anyway it is explained in the SFML tutorials, just have a look at the "getting started" tutorial for Code::Blocks.

In main graphics start up program with codeblocks in build options, in other linker options must put -lsfml-system and in search directories>linker must take the C:\SFML-1.5\lib\mingw directory, and in the compiler stettings>#defines must put SFML_DYNAMIC.
In the program directory must put the sfml-system.dll file to work the program.
-------------------------------------
Now i have the graphics.hpp and i dont know what settings must i do.

Take everything that involves sfml-system, and replace "system" with "graphics"

dkaip · « **Reply #7 on:** January 31, 2010, 07:02:12 pm »

I did that. So in build>debug>linker settings i take -lsfml-graphics but nothing. Also i put sfml-graphics.dll and sfml-graphics-d.dll files in prograsm folder, but program breaks. What next?

Laurent · « **Reply #8 on:** January 31, 2010, 07:13:16 pm »

Did you define SFML_DYNAMIC?

dkaip · « **Reply #9 on:** January 31, 2010, 09:42:13 pm »

Yes and without ...

Code: [Select]

    sf::Font font;
    std::string file = OpenFile( "Arial.ttf" );
    font.LoadFromMemory( file.c_str( ), file.length( ) );

works fine...
Now what i must put?
If helps i can send the hole project.
