[MPlayer-users] undeclared symbol CONFIG_X86_L1_CACHE_SHIFT

[Dr. Bernd Guenther]

-----BEGIN PGP SIGNED MESSAGE-----

Hi Sascha,
I believe that's not quite so. prefetch.h resolve the function prefetch_range 
(apparently used indirectly by MPLAYER - I didn't yet find out how) to 
something containing the symbol PREFETCH_STRIDE. This in turn resolves in 
prefetch.h to 4*L1_CACHE_BYTES and this in turn in asm/cache.h to 
1<<L1_CACHE_SHIFT and this in asm/cache.h to CONFIG_X86_L1_CACHE_SHIFT. The 
latter does NOT resolve, so some include file is apparently missing. I cannot 
figure out if this is a Suse Linux problem (it would be a kernel problem, 
rather, because I understand that these include files are part of the kernel 
source) or an MPLAYER problem.
I switched simultaneously from Suse Linux 9.1 to 9.2 and from MPlayer 1.0pre4 
to 1.0pre5 so I cannot tell which affected the change!
Bernd.
