General / Fatal error after linking

« on: February 28, 2012, 11:53:50 am »

I added the library to my ubuntu and I compiled this code:

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;
}

and everything went well The next code I will compiling is:

Code: [Select]

#include <SFML/Window.hpp>
 
int main()
{
    sf::Window oknoAplikacji( sf::VideoMode( 400, 400, 32 ), "Wprowadzenie" );
    //sf::Window oknoAplikacji;
        //oknoAplikacji.Create( sf::VideoMode( 400, 400, 32 ), "Wprowadzenie", sf::Style::Fullscreen );
 
        while( oknoAplikacji.IsOpened() )
    {
        oknoAplikacji.Display();
    }
    return 0;
}
 

In my terminal I get:

Code: [Select]

lotnik9o@ubuntu:~/Downloads$ g++ -c 1.cpp
In file included from /usr/local/include/SFML/Window.hpp:40:0,
                 from 1.cpp:1:
/usr/local/include/SFML/Window/OpenGL.hpp:47:23: fatal error: GL/gl.h: No such file or directory
compilation terminated.

How can I solve the problem?

« on: February 23, 2012, 01:35:01 pm »

I've a problem to linking this code:

Code: [Select]

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;
}

and I got this errors:

I have to make the SFML headers and library files available to Visual C++ 2008 and after bulid:

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;
}

It gives me the following errors:
