[Solved] OSx Yosemite: x86_64 symbols problem

[Sir_Rai]

I'm using OSx Yosemite (10.10.1) with x86_64 architecture. I just cloned the sfml project from github and compiled it successfully, even the examples provided in the repo. But when I try to compile the tutorial test with the green circle:

(click to show/hide)

#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 have this error:

Code: [Select]

$ clang++ main.cpp -lsfml-graphics                         
Undefined symbols for architecture x86_64:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I used ccmake to build SFML with shared libraries (not the framework thing). Following the tutorial I use clang and the c++11 libs. For the architecture I have placed "i386;x86_64" this is the CMakeCache generated and the configuration. (This is a bit long click spoiler to see)

Checking the libs in /usr/local/lib with file command I see every lib from SFML is universal. Here the output for libsfml-graphics lib:

$ file libsfml-graphics.dylib                  
libsfml-graphics.dylib: Mach-O universal binary with 2 architectures
libsfml-graphics.dylib (for architecture i386): Mach-O dynamically linked shared library i386
libsfml-graphics.dylib (for architecture x86_64):       Mach-O 64-bit dynamically linked shared library x86_64

my clang version:

Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.0.0
Thread model: posix

I have read multiples posts and googling during hours reading about this issue, most of them related with a wrong configuration in cmake or a bad sfml version download. Most people on osx are using xcode (Im not) and the framework solution, but I want to build just shared libs. I'm doing something wrong? I'm new using clang maybe I'm not compiling the main in a proper way. I've tried compiling using  "-std=c++11" "-stdlib=libc++" as arguments with the same results. Any idea guys?

[Hiura]

$ clang++ main.cpp -lsfml-graphics

should be

$ clang++ main.cpp -lsfml-graphics  -lsfml-window -lsfml-system

If you don't want to use Xcode, have a go with the Linux tutorial. There might be some insight there. http://www.sfml-dev.org/tutorials/2.2/start-linux.php

omg it was the problem! <Facepalm> Thank you Hiura
