arm-wince-cegcc is good for porting stuff from unix-like environments,
because it offers all kinds of well known goodies. arm-wince-mingw32ce
is much closer to native Windows CE because it intentionally lacks
those. Both sets of tools have their goals and their advantages and
disadvantages.
The cegcc toolchain was certainly the easiest way to get started.
You'll find further down that it's currently the only way. Keep on
reading ...
I've edited all occurrences of "-lm" out of the configure script
(otherwise it fails on that when you give it the mingw32ce toolchain to
use). Then the configure worked.
Next error was that common.h likes to include <errno.h>. The solution to
this one is simple :
*** common.h~ 2006-12-08 01:35:08.000000000 +0100
--- common.h 2007-01-22 20:33:45.000000000 +0100

*** 38,44 ****
--- 38,46 ----
# include <ctype.h>
# include <limits.h>
# ifndef __BEOS__
+ #ifndef __MINGW32CE__
# include <errno.h>
+ #endif
# else
# include "berrno.h"
# endif
After a while, the build fails with :
/opt/mingw32ce/lib/gcc/arm-wince-mingw32ce/4.1.0/../../../../arm-wince-mingw32ce/include/math.h:355:
error: impossible constraint in 'asm'
That math.h file is from mingw (src/mingw/include/math.h in our svn) so
the problem is probably that this is x86 assembler.
In other words : this is a bug, it prevents you from using the
arm-wince-mingw32ce toolchain for ffmpeg for now.
