You’ll also want to do a pkg-config --cflags SDL2 or sdl2-config --cflags
Right now, your command is only grabbing SDL2_image, which may or may not
reside in the same directory.
Hope that helps,

Ignore my previous mail. The problem is fixed. The pkg-config is
returning -I/opt/SDL/include/SDL2/ .
So i should have added the headers as #include <SDL.h>, not as #include
<SDL2/SDL.h>
Although my code is still not building. It now spits out following error:

Well the problem seems to be that the mouse capture code was written for
earlier version of SDL. Here is the clue, In 1.2.15, there is a macro
definition of SDL_SRCCOLORKEY:
$arif at khost:~/sak/SDL$ hg checkout release-1.2.15
$arif at khost:~/sak/SDL$ global -gx SDL_SRCCOLORKEY
SDL_SRCCOLORKEY 151 include/SDL_video.h #define SDL_SRCCOLORKEY

I know the documentations says to use that, but whenever I try "SDL.h"
the compiler never finds the header files (probably because it’s in
the SDL2 subdirectory) so I end up using <SDL2/SDL.h> instead.
Of course the fact that the headers are not in predictable locations
seems to be a big issue in the first place. Why can’t we just use the
filenames relative to the include path? (yes, the user could be
providing its own include path, but at that point the user would know
what’s going on anyway)
2013/6/11, Sam Lantinga :> You need to include the headers in the following way:
#include “SDL.h” #include “SDL_image.h”

It sounds like you’re still not including the headers in
sdl_mouse_capture.c like Sam recommended: #include “SDL.h”
sdl2-config (or pkg-config) should take care of it for you if you include
the headers appropriately, as above.
To do it the “SDL2/SDL.h” way, you need to specify the path where the SDL2
directory can be found. The extra flags you have, like
-I/opt/SDL/include/SDL2,
are pointing at the SDL2 directory, instead of where it can be found:
/opt/SDL/include

This is fixed. I was including the file etc “SDL/SDL.h” etc, Where
pkg-config is returning /opt/SDL/include/SDL. I should have included it
as “SDL.h”. Thanks for the replyOn 06/12/2013 08:07 PM, Jonathan Dearborn wrote:
