hi all,

i am new to sdl, i am trying to compile the example
given in the sdl documentation for video.

i included the SDL.h file but when compile i got
undefined reference to for example SDL_Init(),
SDL_Quit …and so on.

what does that mean.

looking for your help

You should link with the sdl-libraries while compiling: SDLmain.lib, and
SDL.lib in windows.

I need this line at the top of the source file:

#include <SDL/SDL.h>

I also have to select the SDL library when ompiling with this parameter:

g++ Test.cpp -lSDL

You will also have to make sure that the SDL headers are installed on
your system. Mine are in a seperate package called “libsdl1.2-dev”. You
can check this by looking in the include directory for the SDL.h

Good luck

Try adding:

SDL_Delay(5000);

This will pause for 5 seconds so you can see what is happening. It may
be the case you are opening the display, then closing it quickly.
