General / Re: Linker error I don't understand

And so I'm going to learn CMake. Fortunately there is a tutorial in the "getting started" section of SFML.
Oh, I like coding, but I hate all the configuration und installation work. Nevertheless thanks and a happy new year.

Ok, I've installed TDM with gcc 4.9.2 and the SFML version 2.4.2.
Just the same error message.  3 different calls of "loadFromFile", and all don't work.

Code: [Select]

        if (!backgroundTexture.loadFromFile("background.jpg"))
            return EXIT_FAILURE;

        if (!font.loadFromFile("sansation.ttf"))
            return EXIT_FAILURE;

        if (!texture.loadFromFile("texture.jpg"))
            return EXIT_FAILURE;

BTW: I don't believe that these errors depend on a wrong version. On Linux I use Codeblocks 16.01 together with SFML 2.3.2 (because it's in the Ubuntu repository), and - as I said - it works well.

Hello,
unable to compile the "opengl" example of SFML.


Windows 7,
SFML 2.3.2 - 32 bit,
TDM with gcc 4.8.1
Codeblocks 16.01

I followed exactly the instructions on the SFML tutorial page. All needed files are availabe, and I think codeblocks is well configured. The first example of the tutorial compiles and runs fine, the SFML example "window" too. But trying to compile the example "opengl" I get the error messages below. Just the lines where some ressources have to be loaded.

The same errors I got by trying other combinations of SFML and gcc. On Linux this example works without any troubles.
