sf::Color linker error
« on: May 17, 2011, 06:42:36 pm »
When I try to use the following code

Code: [Select]

        this->selectedColor = sf::Color::Green;
this->deselectedColor = sf::Color::Red;


Where selectedColor and deselectedColor are variables of type sf::Color, I get the following linker error.


Error   11   error LNK2001: unresolved external symbol "public: static class sf::Color const sf::Color::Red" (?Red@Color@sf@@2V12@B)   C:\Users\Daniel\documents\visual studio 2010\Projects\Game Template\Game Template\GButton.obj


THis is followed by an equivilent error for the green color call, and any other colors I use. If I specify the colors manually (sf::Color(0,255,0)), then I get a runtime error that breakpoints me somewhere in the middle of xutility.cpp.

My linker settings are this:
Code: [Select]
sfml-graphics.lib
sfml-window.lib
sfml-system.lib
sfml-audio.lib
sfml-main.lib
opengl32.lib
glu32.lib


and I include <SFML/Graphics.hpp> in the relevant file. What am I doing wrong?

You must read the tutorial carefully, it is explained in bold characters... ;)

In "Getting started": "SFML and Visual Studio"

Important: if you link against the dynamic libraries, you have to define the SFML_DYNAMIC macro in your project's settings. If you don't, you'll get linker errors when compiling your application.

I did everything as shown and I followed what you said but I get 17 errors:
Error   LNK2019   unresolved external symbol "public: __thiscall sf::String::String(char const *,class std::locale const &)" (??0String@sf@@QAE@PBDABVlocale@std@@@Z) referenced in function _main   GameEngine   E:\Programmation\Apps\GameEngine\GameEngine\main.obj   1

... and 14 more for Video::Video, Window::Window etc... Can you help me ?

Sometimes it's useful to look at the date something was posted on. This thread is from 2011 and talks about SFML 1.6, which is very old... ;)

SFML_DYNAMIC doesn't exist in SFML 2.x, just make sure, you're actually linking SFML

SMFL STATIC does exist in SFML 2.* as it is written in the documentations that I followed step by step but get the 17 errors anyway
