[Mplayer-matrox] Re: mga_vid, 2.6, SMP

[Mark Hurenkamp]

Hi,


I tried again to build mga_vid, this time using latest CVS (previously 
1.0-pre5), with the patch mentioned in my earlier mail (still on 2.6.6).
Still I seem to have SMP related problems, see the output at the end of 
the message.
The (first) offending line seems to be this one:
     include/asm/mpspec.h:6:25: mach_mpspec.h: No such file or directory

So lets see where it lives:
nine linux-2.6.6-mh11 # find . -name mach_mpspec.h -print
./include/asm-i386/mach-generic/mach_mpspec.h
./include/asm-i386/mach-default/mach_mpspec.h
./include/asm-i386/mach-bigsmp/mach_mpspec.h
./include/asm-i386/mach-es7000/mach_mpspec.h
./include/asm-i386/mach-numaq/mach_mpspec.h
./include/asm-i386/mach-summit/mach_mpspec.h
nine linux-2.6.6-mh11 #

Ok, there seem to be plenty versions available, why can't it find
any of them (preferably the right one, which would be ??? )?


Next I'll give 2.6.9 a try.


Warm regards,
Mark.
