Title: Dll fails to load when contains SFML opengl functions
Post by: Noah Klabo on July 23, 2014, 08:34:30 am

Im working on an engine that loads a dll that contains all the GUI code, its works if I use
_{In DLL}

 SFWindow = new sf::Window(sf::VideoMode(800, 600), Title);  

but will not load if I use

SFWindow = new sf::RenderWindow(sf::VideoMode(800, 600), Title);

the dll is compiled using

g++ -std=c++0x -shared -o Gui.x86.dll Gui/Gui_Interface.cpp  Gui/Gui_Gui.cpp Gui/Gui_Window.cpp  -Wl,-rpath,'$ORIGIN'  Common.x86.dll  
-lsfml-system -lsfml-graphics -lsfml-window -lOpengl32 -lGlu32

and loaded in main executable

                SharedLibrary GuiLib("Gui.x86","Init");
                InitGui = (GuiInterface (*)()) GuiLib.Function;
                Interface.Gui = InitGui();

I have no Idea why it is doing this thanks

sf::Window needs the Window module; sf::RenderWindow needs the Graphics modules, which needs the window module so it must be the graphics module that is causing you a problem.
I would try to link them in the correct order. I'm not sure which way around it is in your compiler but it will probably be either:

-lGlu32 -lOpengl32 -lsfml-graphics -lsfml-window -lsfml-system

or

-lsfml-system -lsfml-window -lsfml-graphics -lOpengl32 -lGlu32

What does "will not load" mean? Is there an error?

On g++, dependent libraries have to be listed first, i.e. sfml-graphics before sfml-window before sfml-system.
