Title: Linking on Mac OS X
Post by: xqbt on January 05, 2016, 12:43:22 am
After setting everything up on my Windows machine, I thought Mac OS X would be a breeze. Naive me...
So, I am stuck at the  linking stage. Here is the complain statement:
Quote
==== Building new (debug) ====
main.cpp
Linking new
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin12.3.0

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The program itself is a main file which creates a window.
Here is what I have done so far:
Please help.
PS I am using premake for creating makefiles, but I do not think it will bring any new info.

Not sure if it helps/changes a thing but using the most recent version of the tutorial might help:

SpeCter, yeah, I guess those two articles (2.2 and 2.3) aren't very different, but thanks for the reply  :)
I have a strong feeling that something somewhere went very very wrong...

True, but using the wrong one explains this:

... except sndfile.framework. I could not find it anywhere in the SFML package (I suppose snd means "sound", so do I need it?)
;)

Hapax, yes, indeed. Well, there dies another hope of mine for an easy fix.

...

Tried linking dylibs instead of frameworks (removed freetype.framework too) so that now I am linking only graphics, window and system. Same error.

Another piece of puzzle.
This code works:
#include "../lib/SFML/linux/include/SFML/System.hpp"

int main()
{
    sf::Clock c;

    return 0;
}
And this code brings the aforementioned errors:
#include "../lib/SFML/linux/include/SFML/Window.hpp"

int main()
{
    sf::Window w(sf::VideoMode(800, 600), "Test");

    return 0;
}
 

...

Am I missing a dependency somewhere? Window relies only upon the system, right?

...

BTW, I don't have Xcode installed, only command line developer tools. Could that be a problem?
And how is OpenGL linked, anyways?

SOLVED!
The solution was to supply "-stdlib=libc++" flag to the linker (along with "-stdlib=libc++" and "-std=c++11" flags to the compiler).
Thanks all, especially to Deepak for his answer to his own question, which lead me to the solution:
