Small program wont compile [Linux]
« on: July 24, 2016, 04:00:06 am »


    #include <SFML/Window.hpp>
   
    int main()
    {
        sf::Window window(sf::VideoMode(200, 150), "My Window");
   
        while(window.isOpen())
        {
            sf::Event event;
   
            while(window.pollEvent(event))
            {
                switch(event.type)
                case sf::Event::EventType::Closed:
                    window.close();
                    break;
                case sf::Event::EventType::KeyPressed:
                    if(event.key.code == sf::keyboard::Space)
                    {
                        window.setTitle("Space Pressed");
                    }
                    break;
            }
        }
   
        return 0;
    }

When I try to compile the program above with this compile line I get the errors listed below.
g++ -o run2 main.cpp -lsfml-window -lsfml-graphics -lsfml-system



    main.cpp: In function ‘int main()’:
    main.cpp:14:29: error: ‘sf::Event::EventType’ is not a class or namespace
                 case sf::Event::EventType::Closed:
                                 ^
    main.cpp:13:19: warning: enumeration value ‘Closed’ not handled in switch [-Wswitch]
                 switch(event.type)
                       ^
    main.cpp:17:29: error: ‘sf::Event::EventType’ is not a class or namespace
                 case sf::Event::EventType::KeyPressed:
                                 ^
    main.cpp:17:13: error: case label ‘<expression error>’ not within a switch statement
                 case sf::Event::EventType::KeyPressed:
                 ^
    main.cpp:18:42: error: ‘sf::keyboard’ has not been declared
                     if(event.key.code == sf::keyboard::Space)
                                              ^
   

But odly enough if I cut the program down a little it compiles just fine. The program below compile without a problem.



    #include <SFML/Window.hpp>
   
    int main()
    {
        sf::Window window(sf::VideoMode(200, 150), "My Window");
   
        while(window.isOpen())
        {
            sf::Event event;
   
            while(window.pollEvent(event))
            {
                if(event.type == sf::Event::Closed)
                {
                    window.close();
                }
            }
        }
   
        return 0;
    }


My sfml file are stored under /usr/local/include/SFML/

AW: Small program wont compile [Linux]
« Reply #1 on: July 24, 2016, 07:12:06 am »
It's not really odd. In the first code you use the name of the enum in the case statements, which is not how regular enums should be used. While in the seconde code you leave it out.
It should always be sf::Event::KeyPressed, sf::Event::Closed etc
See the tutorial on events. ;)

I revised and took out the EventType as you stated and now I'm getting this error.

main.cpp: In function ‘int main()’:
main.cpp:17:13: error: case label ‘KeyPressed’ not within a switch statement
             case sf::Event::KeyPressed:

Your switch statement has no brackets ("{...}"). They're not optional for switch().

Thanks Mario, that got it. I'm not the greatest in programming anyway but even what I do I rarely use switch statements. I'm following along a video on udemy.com and watched the guy compile that code wihout a problem, he was using Visual Studio and I'm using VIM and g++, I don't know if that would make a difference or not.
