ld:framework not found sfml

I copied the contents of Frameworks from SFML to ~/Library/Frameworks and tried to run the first tutorial example in SFML. I used this in g++ :

g++ -o sfml-test.cpp -framework SFML -lsfml-window

and get this error:

ld: framework not found SFML

Any help would be appreciated.

First of all, the tutorial specifies /Library/Frameworks, not ~/Library/Frameworks. ~ points to the user home directory (/Users/name/), whereas / points to the lowest point on the filesystem.

Also despite the documentation, /Library/Frameworks is not a standard framework directory, so you have to set it in the search paths. You can see the standard framework directories by running gcc -Xlinker -v: 

@(#)PROGRAM:ld  PROJECT:ld64-409.12

Note the Framework search paths section, it does not include /Library/Frameworks.

To add /Library/Frameworks to the search path, compile with -F/Library/Frameworks and link with -F/Library/Frameworks -framework SFML -framework sfml-x, x being system, window, graphics, audio or network.

Also, the -o option specifies the output filename. Your command would take no input files and output the executable sfml-test.cpp, so use -o sfml-test sfml-test.cpp to take sfml-test.cpp as input, and output sfml-test.

Your command would be:

g++ -o sfml-test sfml-test.cpp -F/Library/Frameworks -framework SFML -framework sfml-window
