Basic error

[Kyle]

When following the first window tutorials i encountered this error

1>SFML program.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual __thiscall sf::Window::~Window(void)" (__imp_??1Window@sf@@UAE@XZ) referenced in function _main

Any ideas?

[Laurent]

You have to link to sfml-window.lib.

[Kyle]

Ah thank you

[Kyle]

I got more errors, i think i have not followed the instructions correctly xD

Here is code:

Code: [Select]

#include "stdafx.h"
#include <SFML/System.hpp>

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

using namespace sf;
using namespace std;
int main()
{
    // Create the main rendering window
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");
   
    // Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
        }

        // Clear the screen (fill it with black color)
        App.Clear();

        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}

You haven't linked to sfml-graphics.lib.

The rule is simple: if you include <SFML/Xxx.hpp> then you have to link to sfml-xxx.lib. SFML is split into modules, you have to adjust the compiler/linker options for each module that you use.

First-chance exception at 0x43003d00 in SFML program.exe: 0xC0000005: Access violation reading location 0x43003d00.
A buffer overrun has occurred in SFML program.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program.

For more details please see Help topic 'How to debug Buffer Overrun Issues'.


it points to this piece of code:
  App.Clear(sf::Color(200, 0, 0));

[Laurent]

Link to the debug libraries (suffix "-d") when you compile in debug mode.

Hey, this one is written in the tutorials

[Kyle]

Sorry, but your tutorials are very good but sometimes i become a bit confused, Is there some were i can look up more on Events?

[Laurent]

Sorry, but your tutorials are very good but sometimes i become a bit confused

That's why this piece of information is written in the "getting started tutorial", with the word "important" in bold/blue font to start the paragraph.

Is there some were i can look up more on Events?

In the "Handling events" tutorial :roll:
And in the API documentation, of course.

[Kyle]

Microsoft Visual Studio C Runtime Library has detected a fatal error in SFML program.exe.

Press Break to debug the program or Continue to terminate the program.

[Kyle]

Is it another obvious reason it is not working that i am missing xD

[phear-]

Do you even know C++? If not I would highly recommend you read some books or tutorials on it.

[Kyle]

Ok now, i can see where this is going, yes i do.

[phear-]

The reason I ask is because you use:

Code: [Select]


using namespace sf;


but then later on in your code you use

Code: [Select]


sf::


[Kyle]

Yea, i was wondering if i was not understanding correctly, and i was told why it was like that.

Why does the error i have now point to this line?

while (App.GetEvent(Event))

EDIT:
oh sorry i thought you were referring to one of my earlier topics, no i do that because i was testing something  and forgot to remove it xD
