I have been unable to compile a basic class file to generate a window using SDL2, using both brew and compiling from the SDL site using using...
#include <SDL2/SDL.h>
at the top of the file.
Have also used...
#include <SDL/SDL.h>
#include "SDL"
among others and nearly always get this error
./src/window.cpp:1:10: fatal error: 'SDL2/SDL.h' file not found #include <SDL2/SDL.h>
Something should have worked and just hasn't.
