Well you shouldn't. If your code depends on the libraries, you need to put them in front of the linker arguments.
Just because something works on system X doesn't mean it's generally correct.

I'm not sure what you mean by linker. I'm linking only at runtime

In your build command, did you place your cpp file after the linker arguments?

Yes  But as I said, this code works on ArchLinux but not on my Ubuntu

Well I include these headers in the lib I'm calling with dlopen:

#include <SFML/Graphics.hpp>
#include <SFML/Window/Keyboard.hpp>

Is that enough ?

undefined symbol: _ZN2sf5Color5BlackE

I compile my graphic lib with

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

. This lib includes all the SFML stuff.
I then link at runtime but dlopens fails with the error I gave in the first post.

General / Problem with colors on Ubuntu

Hi,
I recently (yesterday) installed libsfml-dev on Ubuntu 16.04, and I get a weird error while trying to load my graphic lib (using sfml) trough dlsym:

undefined symbol: _ZN2sf5Color5BlackE

I tried on an other system (ArchLinux) and everything works fine. This is the part causing problem :

sf::Color::Black

I tried to change the color (to :

sf::Color::Blue

), and the error becomes

undefined symbol: _ZN2sf5Color5BlueE

So the error is from sf::Color
Any ideas ?
