'“SDL.h” no such file or directory found' when compiling

Question

Here\'s a piece of my current Makefile:

CFLAGS = -O2 -Wall -pedantic -std=gnu++11 `sdl-config --cflags --libs` -lSDL_mixer

I have libsdl instal

Answer 1

header file lives at

/usr/include/SDL/SDL.h

       __OR__

/usr/include/SDL2/SDL.h  #  for SDL2

in your c++ code pull in this header using

#include 

       __OR__

#include     // for SDL2

you have the correct usage of

sdl-config --cflags --libs

       __OR__

sdl2-config --cflags --libs   #  sdl2

which will give you

-I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT
-L/usr/lib/x86_64-linux-gnu -lSDL

       __OR__

-I/usr/include/SDL2 -D_REENTRANT
-lSDL2

at times you may also see this usage which works for a standard install

pkg-config --cflags --libs sdl

       __OR__

pkg-config --cflags --libs sdl2   #  sdl2

which supplies you with

-D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL -lSDL

       __OR__

-D_REENTRANT -I/usr/include/SDL2 -lSDL2   #  SDL2
