Problems compiling with SDL

) ./configure fails because sdl-config --libs returns
-Lc:/mingw/lib -lmingw32 -lSDLmain -lSDL -mwindows
which is insufficient. -lwinmm and -ldxguid are also
required.
I modified sdl-config so that it returned
-Lc:/mingw/lib -lmingw32 -lSDLmain -lSDL -lwinmm -ldxguid
-mwindows


2) Duplicate symbol errors
(IID_IDirectDraw7,IID_IDirectDrawcolorControl) in 
libdxguid.a and
libvo/vo_directx.c. I looked in libvo/directx.c and found
the following:
* DirectDraw GUIDs.
* Defining them here allows us to get rid of the dxguid
library during
* the linking stage.
************************************************************
*****************/

const GUID IID_IDirectDraw7 =
{
	0x15e65ec0,0x3b9c,0x11d2,{0xb9,0x2f,0x00,0x60,0x97,0x97,0xe
a,0x5b}
};

const GUID IID_IDirectDrawColorControl =
{
	0x4b9f0ee0,0x0d7e,0x11d0,{0x9b,0x06,0x00,0xa0,0xc9,0x03,0xa
3,0xb8}
};

So what if dxguid has to be included? Remember, it is not
included, then
configure fails. It is part of w32api, although it seems
that the
current w32api headers do not define some constants used by
MPlayer.
After I upgraded w32api (thinking that maybe it was
outdated), I had to
re-install the MPlayer dx7 headers.

Anyway, I commented out these definitions.

3) Finally, during link, the SDL libraries could not find
GDI functions.
It seems that the -mwindows was removed from the libs
returned
by sdl-config. To work around this, I added -lgdi32 so that
sdl-config
returned
-Lc:/mingw/lib -lmingw32 -lSDLmain -lSDL -lwinmm -ldxguid
-mwindows
-lgdi32.

Imho this is a SDL bug it should not force things like
-mwindows...

Would it also work if you make them static? Defining these
GUIDs directly here 
makes MPlayer also work on systems without directx.

Is SDL working correct nowadays? It had some problems with
the overlay when 
MPlayer was ported to windows.

To be honest, I may be the culprit. I noticed that the
undefined symbols 
were coming from GDI and the Multimedia API, so I probably
added -mwindows 
as a shortcut. I have taken it out, as it (naturally) caused
the console 
output to disappear.

I would have to try, but I probably won't bother. SDL is
working.  The only 
reason that I installed it is that one day I decided to
compile MPlayer with 
support for as many libraries as possible, whether I need
them or not.

It seems to work, but my requirements are simple, and I am
easily satisfied. 
  I type "mplayer -vo SDL <movie-name>".
If the movie plays, then I am 
happy, and if it does not ... Right now I am happy.
