For Simple Direct Media Layer 2  SDL2   after installing it on Ubuntu 16 04 via     sudo apt-get install libsdl2-dev   I used the header      include  lt SDL2 SDL h gt      and the compiler linker command     -lSDL2main -lSDL2    Additionally  you may also want to install     apt-get install libsdl2-image-dev   apt-get install libsdl2-mixer-dev   apt-get install libsdl2-ttf-dev     With these headers      include  lt SDL2 SDL image h gt   include  lt SDL2 SDL ttf h gt   include  lt SDL2 SDL mixer h gt      and the compiler linker commands    -lSDL2 image  -lSDL2 ttf  -lSDL2 mixer

Most times SDL is in  usr include SDL  If so then your  include  lt SDL h gt  directive is wrong  it should be  include  lt SDL SDL h gt    An alternative for that is adding the  usr include SDL directory to your include directories  To do that you should add -I usr include SDL to the compiler flags     If you are using an IDE this should be quite easy too

the simplest idea is to add pkg-config --cflags --libs sdl2 while compiling the code   g   file cpp  pkg-config --cflags --libs sdl2

If the header file is  usr include sdl SDL h and your code has    include  SDL h    You need to either fix your code    include  sdl SDL h    Or tell the preprocessor where to find include files   CFLAGS       -I usr include sdl

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  lt SDL h gt            OR     include  lt SDL2 SDL h gt        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
