How do you include files in C++ from the /Library/Framework folder in MAC

Question

I am trying to use SDL. I have a folder in /Library/Frameworks called SDL2.framework. I want to include the file SDL.h in my project.

Answer 1

you will want to make a build script for this obviously, but the important parts are:

-I/usr/local/include or wherever your headers get installed.

I used home brew:

brew install sdl2

which puts the libraries in /usr/local/Cellar/

so if you need to specify the lib path you will also add:

-L/usr/local/lib -lSDL2

I also changed your include line to #include <SDL2/SDL.h>

Answer 2

Your header files is under the Headers folder, so in order to include this properly:

clang++ -std=c++11 -stdlib=libc++ -I/Library/Frameworks/SDL2.framework/Headers/

But I recommend Installing with homebrew:

brew install sdl2

Homebrew will install SDL2 libSDL2.a file under /usr/local/lib and /usr/local/include, so you will just need to include this Library path using the -L for library and -I flag to add search in /usr/local/include dir:

clang++ -std=c++11 -stdlib=libc++ main.cpp -I/usr/local/include -L/usr/local/lib -lSDL2 -o programfile

And include:

#include <SDL2/SDL.h>
