Error in compilation test project VC8 c++
« on: February 17, 2014, 07:29:46 pm »
Hi, here as create new project win32. But I have a problem.
Here my step:
File->New->Project Win 32 project
next-> empty project
source(right mouse press) add-> new item main.cpp -> ok

http://sfml-dev.org/tutorials/2.1/start-vc.php

Then (right mouse press) in project -> propereties

All configurations
C++ -> General -> AID(aditional include directores) -> D:\sfml\include
linker -> Generals -> AID ->D:\sfml\lib
Debag
linker-> input additional dependencies->
sfml-graphics-d.lib
sfml-window-d.lib
sfml-system-d.lib
sfml-audio-d.lib

Copy test code in main.cpp:
#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

ctr+F5
Errors!!! =)

Quote from the very tutorial you linked...

If you chose to create a "Windows application" project, then the entry point of your code has to be the "WinMain" function instead of "main". Since it's Windows specific, and your code would therefore not compile on Linux or Mac OS X, SFML provides a way to keep a standard "main" entry point in this case: link your project to the sfml-main module ("sfml-main-d.lib" in Debug, "sfml-main.lib" in Release), the same way you linked sfml-graphics, sfml-window and sfml-system.

And on top of that I highly suggest upgrading to a newer compiler to take advantage of C++11 features (VC++8 is extremely outdated).  ;)

And by the way, this is not related to CSFML  ::)

In this case - since we are dealing with the C bindings - I guess it would be to take advantage of C99/C11 features (does the MS C compiler actually support any bits of C11? I know their C99 support has been lacking but getting better; but C11??).
(I'm not a Windows person but still currious)

Ohh and by the way; what you've got there is not a compilation error - it's a linking error.

Please don't double post, there is an edit button  ;)

This is not a C binding issue, for crying out loud - does the code or libs he is trying to link look like C?

No need to be getting picky with terminology.

Using WinMain i me error. Look here:

Code:
#include <SFML/Graphics.hpp>

int WinMain()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

#1 Read what I kindly linked you from the tutorial.
#2 Try reading and understanding error messages, this is a vital skill - at least try googling the error message.

I read Google before creating threads.
Minor bugs I understand, but not those evil!!! >:(

Can screen create?

EXAMPLE Please enter the studio!!!

Or how to make that the console does not display when the program run

Did I do that? I don't see a double post here - unless you think my two replies should have been one.. Sorry if I should have merged them.

Nope. But it was posted in the C bindings forum for some reason, so I just assumed that C was the target that he wanted to discuss.

Linking is a sub process of compilation, no need to be getting picky with terminology.

I'm not trying to "get picky", but understanding the difference between errors that occur during pre-processing, compilation, linking and run-time linking/execution can sometimes be critical in quickly figuring out what went wrong. Every competent developer should understand the difference between them and pointing out the specifics is not something I consider "picky".

Ah yes, I understand what went wrong, but I do not write correctly comes winMain(). If you are prompted example of the work I would have been easier.
