Hey guys,
i keep getting a LNK 2019 error in visual c++ 2008 express:

based on the code i copied from the tutorial:
#include <SFML/Window.hpp>
int main(){
// Create the main window
sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");
bool Running = true;
while (Running)
{
App.Display();
}
return EXIT_SUCCESS;
}
the previous tutorial involving threading and even the very first script with timing worked fine for me so i believe i have appropriately linked to the appropriate SFML:
include files:

and library files:
(http://img251.imageshack.us/img251/931/14698135.jpg)
as a matter of interest, I am linking to the microsoft SDK based on advice given on this thread from about a year or two ago:
http://www.sfml-dev.org/forum/viewtopic.php?t=244
I also researched heavily and came accross this link, but found that it did not help me:
http://www.sfml-dev.org/forum/viewtopic.php?t=1553&highlight=lnk2019
I also have the following aspects established under my project properties:

finally, i am running windows 7, and the ATI Radeon HD 5750 graphics card.
any help would be greatly appreciated.

YOu need to link to sfml-window, too.
Edit: I saw your active configuration is "Debug". Therefore you need to link to "sfml-system-d" and "sfml-window-d".
-
thank you for your response
however,
i am getting the following error:
>LINK : fatal error LNK1104: cannot open file 'sfml-system-d;sfml-window-d.obj'
under additional dependencies
i just put
sfml-system-d;sfml-window-d
any ideas?
thank you
Edit: do i have to change my preprocessor from SFML_DYNAMIC to something else since im running the debug mode? Or do i have to paste the sfml-system-d and sfml-window-d files into the debug directory of my Visual basic project folder?
-
It appears you forgot the ".lib" at the end. You should be linking against "sfml-system-d.lib" and "sfml-winodw-d.lib".
-
thank you both for your help so far
i feel we are getting closer to the exact root of the problem
after adjusting the linker input to exactly
Additional dependencies: sfml-system-d.lib;sfml-window-d.lib
i am now getting the following error:
1>LINK : fatal error LNK1104: cannot open file 'sfml-system-d.lib;sfml-window-d.lib'
any help would be greatly appreciated
thank you
-
It thinks the two files are the same file. Have you tried separating with spaces(I don't use MSVC, but it's worth a shot)
-
I have the same problem, but i have done everything to prevent it. My vc++ just doesn't seem to be able to find sfml.system-d.lib and sfml.graphics-d.lib :(
LINK : fatal error LNK1104: cannot open file 'sfml.system-d.lib'
Checked it multiple times. Maybe it has something to do with compilers settings? Altough everything seems to be set and linked right.
EDIT: i was using the graphics tut, but the idea is the same.
-
Can you describe what you did?
-
Have you included the 'lib' folders of SFML, too?
bye, CBenni::O
-
Unless you renamed the files, you should be linking against "sfml-sytem-d.lib" and "sfml-graphics-d.lib". There should be a hyphen ("-") in between instead.
-
Ah, yes, how did i miss that? Thank you!
Then i had the same problem, that OP did - unresolved externals. But linking to sfml-window-d.lib as well, fixed it. The question is - why do i have to use both window and graphics libraries? In the tutorial it is said, that graphics library has the functions needed.
-
In the tutorial it is said, that graphics library has the functions needed
The tutorial says that <SFML/Graphics.hpp> includes <SFML/Window.hpp>, nothing more.
-
Sorry, then it must be my lack of english knowledge.
Thanks for all the help, this library really is simple to learn, getting hang of it right now!
-
Still having problems with setting up :/
Everything went fine, till text tutorial. VC++ started giving me these errors, when exiting the app:
(http://img25.imageshack.us/img25/9036/errrorj.png)
Wasn't able to find a way to get rid of it, so now I'm asking again for help.
EDIT: i had CodeBlocks, so i tried to set up on them aswell, and it has the same problem. What am i doing wrong?
-
This is a known bug with sf::String. It doesn't happen if you link to the SFML static libraries.
-
Yes, that fixed it, and i also got the order wrong, everything is working great now! 8)
