Title: Code::blocks compilation error
Post by: sglorz on April 02, 2011, 11:40:55 pm

I have these undefined references when I compile my project on Code::Blocks (MingW):

I've rebuild the master SFML on GIT with CMake without any error (very clean build system by the way :wink:).

I link with these:

-mthreads
-lsfml-system-s
-lsfml-window-s
-lsfml-graphics-s
-lopengl32
-lglu32

So, what did I miss?

You missed this:

Quote from: "The tutorial"

When linking to multiple SFML libraries, make sure you link them in the right order, as it's important for MinGW. The rule is the following : if library XXX depends on (uses) library YYY, put XXX first and then YYY. An exemple with SFML : sfml-graphics depends on sfml-window, and sfml-window depends an sfml-system. The link options would be as follows :

-lsfml-graphics
-lsfml-window
-lsfml-system

I still have linking problems:

What is the problem here? It looks like there is a wrong compilation option...

You must define SFML_STATIC when you use static libraries.

Ok, I thought there was only a define for dynamic libs.

Thanks again Laurent, your support confirm my choice for SFML.

That was true for SFML 1.6, but it has changed in SFML 2 (and it's not documented yet).
