#include "SDL/SDL.h" Vs. #include "SDL.h" ???


Hi,

I use SDL to design cross-platform video games.

Which is the correct method to include SDL in my sources?
#include "SDL/SDL.h"
OR
#include "SDL.h"

On Linux it seems to be: #include "SDL/SDL.h"
and
on Windows it seems to be: #include "SDL.h"

Just trying to have 1 code base for all platforms.
My current (ugly) solution is the following:
//------------------------------------------------------------------------------
#ifdef WIN32
#include "SDL.h"
#include "SDL_image.h"
#include "SDL_ttf.h"
#include "SDL_opengl.h"
#else
#include "SDL/SDL.h"
#include "SDL/SDL_image.h"
#include "SDL/SDL_ttf.h"
#include "SDL/SDL_opengl.h"
#endif
//------------------------------------------------------------------------------

Anyone have an ideas about this?
Thanks...

No. "sdl-config --cflags" outputs -I/usr/include/SDL (among other
things), so the code should read also #include "SDL.h".

It is recommended to use "SDL.h" on every platform.  Use compiler options or project options (depending on your IDE) to add the .../include/SDL path to your compiler search directories.  For gcc, this is something like -I/usr/include/SDL.  This is what I do, but it's even better to use `sdl-config --cflags` (backticks necessary) and use `sdl-config --libs` as a linker option.

Backticks when calling from a shell, but in a Makefile you can (and I think
should?) do it as, e.g.:

SDL_CFLAGS=$(shell sdl-config --cflags)
SDL_LIBS=$(shell sdl-config --libs)

Just mentioning...

In addition, in bash shell at least, you can use $() instead of the backticks:

$(sdl-config --cflags)
$(sdl-config --libs)

On the Mac, 10.5.8, ppc, I cannot find "sdl-config" in the official distribution of SDL.
Specifying -FSDL to the compiler is not enough to let it find the SDL framework.

Naturally, the <SDL/SDL.h> version works, but apparently that's a no-no (odd, as lots of packages seem to like being packaged inside a directory). Do I really need to add 5 -I statements for the 5 frameworks for SDL to work?

Also: Should the include statement be

#include "SDL.h"
or
#include <SDL.h>

Somehow, I thought that quotes were for your local project includes and the angle brackets for system includes.

#include <SDL/SDL.h> with work for your SDL Framework on OS X, but
then you would need to do:
#include <SDL_image/SDL_image.h>
#include <SDL_mixer/SDL_mixer.h>
etc.

For frameworks, the "path" is actually the framework name.

#include "SDL.h" is recommended for maximum code portability. Some
distributions don't always put things in a directory called "SDL".
Haven't verified in awhile, but once upon a time, FreeBSD put
everything in a directory called SDL11 (even though it was 1.2). And
obviously, OS X frameworks are going to have issues.

So yes, you will need to add a long string of -I statements if you
don't do the #include <SDL_image/SDL_image.h> stuff. I don't think
you'll need the -F flags though since your frameworks are in standard
locations and the linker will find these correctly/automatically.

Some systems have special or different search paths for angle brackets
than quotes. Generally speaking, quotes are better for things that
aren't in these special compiler paths.

I solved this problem two ways in my days of Mac OS X developing before Apple stabbed the FOSS community in the back Sad

Solution A) Create your own sdl-config. It's really simple.

Solution B) Write a little more code to include the necessary headers. Here's how I accomplished that:

#ifdef APPLE
#  include <SDL/SDL.h>
#  include <OpenGL/GL.h>
#else
#  include <SDL.h>
#  include <GL/gl.h>
#endif

Of course that solution is just from memory of many years ago, so it has a few rough edges. When you or someone else tries to build your package on another system, it quickly becomes apparent what the problem is and a fix is usually easy to implement, so the absence of a real standard portable one-liner isn't that critical Smile

Add the additional platform dependant include/link paths and flags to your build system files (makefiles, cmakelists.txt, xcode project, visual studio project....).


It's always better to modify a project setting to make a project build on a particular platform/machine/enviroment that have to modify the sources with the risk of breaking the build on another platform or enviroment.



Also, as Eric says, always use "" for non-system headers, not <>.

I concur. And FYI, CMake already handles this case correctly and
transparently if you use #include "SDL.h"
#include "SDL_image.h"
et al.

I made sure of that Wink
