Problem
Makefile doesn't appear to be able to locate compiled lib file, on local machine !?
Attempting to link "/usr/local/Cellar/sfml/2.5.1_1/lib/llibsfml-graphics.2.5.1.dylib" library, however, linker is not able to locate !?

ld: library not found for -llibsfml-graphics.2.5.1
Goal
Try to understand how to (either) link to a pre-compiled *.dylib file, or create my own with the lib *.hpp files, and then link
CodePudding user response：
On systems where you use libX.a (or libX.so, or libX.dylib like on macOS) libraries, the name of the library is X.
You should not include the lib prefix or the suffix (.a or .so or .dylib). Those are added by the linker automatically when searching for the library.
The name of the sfml-graphics.2.5.1 library is just that, and it's the name you should use: -lsfml-graphics.2.5.1
CodePudding user response：
Forgot to include -lsfml-system.2.5.1 and -lsfml-window.2.5.1 to my LIBS variable... meow everything compiles correctly.
Changed:
LIBS := -lsfml-graphics.2.5.1
to
LIBS := -lsfml-graphics.2.5.1 -lsfml-system.2.5.1 -lsfml-window.2.5.1
Many thanks !
