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. How do I do this? My code looks like:
// Example program:
// Using SDL2 to create an application window
#include <SDL.h>
#include <stdio.h>
int main(int argc, char* argv[]) {
SDL_Window *window; // Declare a pointer
SDL_Init(SDL_INIT_VIDEO); // Initialize SDL2
// Create an application window with the following settings:
window = SDL_CreateWindow(
"An SDL2 window", // window title
SDL_WINDOWPOS_UNDEFINED, // initial x position
SDL_WINDOWPOS_UNDEFINED, // initial y position
640, // width, in pixels
480, // height, in pixels
SDL_WINDOW_OPENGL // flags - see below
);
// Check that the window was successfully made
if (window == NULL) {
// In the event that the window could not be made...
printf("Could not create window: %s\n", SDL_GetError());
return 1;
}
// The window is open: enter program loop (see SDL_PollEvent)
SDL_Delay(3000); // Pause execution for 3000 milliseconds, for example
// Close and destroy the window
SDL_DestroyWindow(window);
// Clean up
SDL_Quit();
return 0;
}
The error I get is:
Aarons-MacBook-Air:SDL aaron$ g++ main.cpp
main.cpp:4:10: fatal error: 'SDL.h' file not found
#include <SDL.h>
^ 1 error generated.
How do I properly include the SDL file? It is inside SDL2.framework
, headers
, SDL.h
...
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>
