General / Netbeans "No documentation found"

« on: August 25, 2013, 08:33:50 pm »

Hi, I recently set up SFML 2.1 on my linux machine, I have it working with netbeans but whenever the auto-complete box pops up I get no suggestions, other than a message "No documentation found". Does anyone know where the SFML documentation live? I assume SFML/doc/ but I am probably wrong. Also how can I get netbeans to use the documentation for auto-complete assistance ?

Thanks in advance

General / Re: Getting SFML working on Ubuntu based Linux

Thanks for pointing me in the rite direction.
I followed this tutorial:
http://www.sfml-dev.org/tutorials/2.1/compile-with-cmake.php

It was a bit intimidating at first but I got there step by step.
I'd suggest for other newcomers attempting this install, synaptic package manager if you haven't got it already :

sudo apt-get install synaptic

It makes finding the correct packages actually possible!

Also installing the gui cmake tool as suggested in the tutorial makes the terminal a lot less cluttered :

sudo apt-get install cmake-qt-gui

I think that's about it, I hope this can help others

General / Getting SFML working on Ubuntu based Linux

Hi everyone, I'm sure similar questions have been asked but my issue is probably very straight forward for those in the know, and I figure I'll probably just confuse things even more if I try and adapt other peoples solutions considering I'm not 100% confident about tackling the issue (hence the reason I am here).

I'm running ElementaryOS Luna (Ubuntu based) running kernel 3.8.

I have gcc version 4.6.3 installed, and as expected it works perfectly fine with Netbeans with respect to compiling C++ programs.

I'm following this tutorial: http://www.sfml-dev.org/tutorials/2.1/start-linux.php.
So far I have run sudo apt-get install libsfml-dev.
No problems there.

I copied the following code and saved it to a .cpp file :

#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;
}

I then ran g++ -c main.cpp and it compiled fine.

Next up I run g++ main.o -o sfml-app -lsfml-graphics -lsfml-window -lsfml-system  as per the tutorial linked above. That's when it all goes wrong, terminal output is as follows :

james@LunaBook:~$ cd NetBeansProjects/
james@LunaBook:~/NetBeansProjects$ g++ main.o -o sfml-app -lsfml-graphics -lsfml-window -lsfml-system
main.o: In function `main':

collect2: ld returned 1 exit status

So I think there is some issue with things not being visible to the linker?

If someone could explain to me how I can fix this problem and linker problems in general it would be greatly appreciated.

Thanks in advance.
