General / SFML 2.0 Error while loading shared libraries libglew.so.1.5 while executing

« on: January 18, 2016, 11:10:29 am »

I am trying to install SFML2.0 on Ubuntu 15.10 but I am having issues during the execution of the file.

The code that I want to execute is the following.

#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 compile the code with the following command:
g++ -Wall main.cpp -o main.o -L/usr/local/lib -I/usr/local/include
-lsfml-graphics -lsfml-window -lsfml-system

and the compilation works fine! However, when I try to execute ./main.o I am getting

./main.o: error while loading shared libraries: libGLEW.so.1.5: cannot open
shared object file: No such file or directory

I already had an error message related to libGLEW.so.1.5 while compiling of the same code saying

/usr/bin/ld: warning: libGLEW.so.1.5, needed by /usr/local/SFML-2.0/lib/libsfml-graphics.so,
not found (try using -rpath or -rpath-link)

However, the installation with of libGLEW.so.1.5 with apt-get install libglew1.5 solved the issue in the compilation and the the problem right now is in the execution of the file. Do you have any ideas what can I do to solve the problem? Thank you!

General / SFML 2.0 Linux installation issue

« on: January 17, 2016, 08:35:40 pm »

Hello,
I am trying without sucess to install SFML 2.0 on a Ubuntu 15.10. Up until now, I worked on SFML in Windows CodeBlocks and I didn't have any serious issues with the installation under Windwos.

However, I am having a lot of trouble when trying to install SFML 2.0 on Ubuntu depsite following the tutorial in the SFML website. I  downloaded the Linux archive from the link http://www.sfml-dev.org/download/sfml/2.0/. After that I extracted the archive to /usr/local/ directory. I try to compile the code main.cpp from the following tutorial: http://www.sfml-dev.org/tutorials/2.0/start-linux.php
When I compile the code with:
g++ main.cpp -o main.o -L/usr/local/include -lsfml-graphics -lsfml-window -lsfml-system
I get:
/usr/bin/ld: cannot find -lsfml-graphics
/usr/bin/ld: cannot find -lsfml-window
/usr/bin/ld: cannot find -lsfml-system

When I compile the code simply with:
g++ main.cpp -o main.o -lsfml-graphics -lsfml-window -lsfml-system
I am getting:
fatal error: SFML/Graphics.hpp: No such file or directory.

Can you tell what should I do to install properly SFML 2.0 on my machine?
Thank you in advance.

General / SFML use in Linux and Windows at the same time

« on: December 12, 2015, 02:02:15 pm »

Hello,
I will write a very simple game in C++ and I consider using the SFML library.I will write the game in Windows 7 but I want to be able to compile it and to execute it in Linux as well. How can I do that? If I use the Windows version of SFML does it mean that the code written in Windows will compile also in Linux? If no, then I may use a Linux emulator in Windows. Which emulator would you advice me to use that is compatible with SFML?
Thank you for your reply.
