Title: Error: LNK2019
Post by: Wesloth on February 28, 2008, 10:56:09 pm

Hi,
I am really new to C++, so i hope you can help me with my problem.
I tried the tutorial and at beginning all worked well.
This worked well:

Code: [Select]

#include <SFML/System.hpp>
#include <iostream>

int main()
{
    sf::Clock Clock;
    while (Clock.GetElapsedTime() < 5.f)
    {
        std::cout << Clock.GetElapsedTime() << std::endl;
        sf::Sleep(0.5f);
    }

    return 0;
}
After that i tried this one:

Code: [Select]

include <SFML/Window.hpp>
#include <iostream>

int main()
{
    sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");
    return 0;
}
But my IDE said:

Blub.obj : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""public: virtual __thiscall sf::Window::~Window(void)" (??1Window@sf@@UAE@XZ)" in Funktion "_main".
Blub.obj : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""public: __thiscall sf::Window::Window(class sf::VideoMode,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,unsigned long,int)" (??0Window@sf@@QAE@VVideoMode@1@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@KH@Z)" in Funktion "_main".

And i dont know what this should be :shock:

Sorry for my english, it's not my native language.

have you added all the necessary additional dependencies?

To use the Window package, you must link to sfml-window in addition to sfml-system.

Thanks, that helped.
But now i get the error:

LINK : fatal error LNK1104: Filei "sfml-window.obj" can not be opened.

edit:
And when i, instead of sfml-window, write sfml-window.lib i get this :shock:

You must still link with sfml-system.lib.

And if you compile in debug configuration, you must use debug libraries instead (sfml-window-d.lib and sfml-system-d.lib).

For all the newbies out there, I found that I also had to turn off Precompiled Headers, in Visual Studio 2008, in order to get my first sample program to work.

Click on Project -> Project Properties
Go to Configuration Properties -> C/C++ -> Precompiled Headers
Change Create/Use Precompiled Header to "Not Using Precompiled Headers"

If this information is wrong, I appologize.   But it is what I had to do in order to get it to work for me.

I don't think there's something in SFML that prevents from using precompiled headers. Maybe you just didn't use it properly ;)

Bit late response here: In your second source code you forgot the # before include...
