 ```
 - raylib installs a pkg-config file, which describes the necessary compilation and linker flags to use it with `yourgame`:
 ```
-cc yourgame.c `pkg-config --libs --cflags raylib` -o YourGame
+cc yourgame.c -std=c++11 `pkg-config --libs --cflags raylib` -o YourGame
 ```
 - If the build fails, you may need to run the following command with the required frameworks
 ```
-cc yourgame.c -framework IOKit -framework Cocoa -framework OpenGL `pkg-config --libs --cflags raylib` -o YourGame
+cc yourgame.c -framework IOKit -framework Cocoa -framework OpenGL -std=c++11 `pkg-config --libs --cflags raylib` -o YourGame
 ```
 
 You may get an error, complaining that the `pkg-config` command was not found. You can use `brew install pkgconfig` to fix that.
