symbol(s) not found in architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am getting this "symbol(s) not found in architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)." Actually, these messages didn't appear until I upgraded to macOS Mojave.

The complete message I got is:

g++  -o bin/Debug/sfm obj/Debug/main.o

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The code is:

#include <SFML/Graphics.hpp>

int main()
{
sf::RenderWindow window(sf::VideoMode(400, 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;
}

Please help.

Updated Answer - May 2019

It seems that the openal package is no longer in homebrew and that causes the instructions below to fail. I don't know the background behind it. Here is another approach.

You can find all the pkg-config related parts of sfml like this:

find /usr/local/Cellar/sfml -name \*pc

/usr/local/Cellar/sfml/2.5.1/lib/pkgconfig/sfml-network.pc
/usr/local/Cellar/sfml/2.5.1/lib/pkgconfig/sfml-all.pc
/usr/local/Cellar/sfml/2.5.1/lib/pkgconfig/sfml-graphics.pc
/usr/local/Cellar/sfml/2.5.1/lib/pkgconfig/sfml-audio.pc
/usr/local/Cellar/sfml/2.5.1/lib/pkgconfig/sfml-system.pc
/usr/local/Cellar/sfml/2.5.1/lib/pkgconfig/sfml-window.pc

It seems you cannot use sfml-all nor sfml-audio in the above list, so you will need to pick which parts you want to use and grab them individually, so if you want graphics, window and system:

pkg-config --libs --cflags sfml-graphics
-I/usr/local/Cellar/sfml/2.5.1/include 
-I/usr/local/opt/freetype/include/freetype2 
-I/usr/local/Cellar/sfml/2.5.1/include 
-L/usr/local/Cellar/sfml/2.5.1/lib -lsfml-graphics -lsfml-window -lsfml-system

pkg-config --libs --cflags sfml-system
-I/usr/local/Cellar/sfml/2.5.1/include 
-L/usr/local/Cellar/sfml/2.5.1/lib -lsfml-system

pkg-config --libs --cflags sfml-window
-I/usr/local/Cellar/sfml/2.5.1/include
-L/usr/local/Cellar/sfml/2.5.1/lib -lsfml-window -lsfml-system

So, you would compile with:

g++ main.cpp $(pkg-config --libs --cflags sfml-window sfml-system sfml-graphics) -o main

Original Answer

If you installed sfml via homebrew, I would suggest you also install pkg-config like this:

brew install pkg-config

Then you can get the switches needed to compile with:

pkg-config --libs --cflags sfml-all

Sample Output

-I/usr/local/Cellar/sfml/2.4.2_1/include -L/usr/local/Cellar/sfml/2.4.2_1/lib -lsfml-graphics -lsfml-window -lsfml-audio -lsfml-network -lsfml-system

So you can compile with:

g++ main.cpp $(pkg-config --libs --cflags sfml-all) -o main
