[MPlayer-dev-eng] mga_vid.c smp problem

[Peter Magnusson]

Hi.

I use MPlayer-1.0pre6a. Compiled with:
./configure --enable-gui --enable-menu --enable-mga --enable-xmga 
--with-reallibdir=/usr/lib/win32 --with-xanimlibdir=/usr/lib/win32
I use gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
I use FC3 with kernel 2.6.10-1.770_FC3smp. I dont have smp but got a HT 
processor so thats the reason that I use smp.

mga-vid-2.6.10-2005-01-11.tar.gz wont build on my smp box :(

However, mga-vid-2.6.11-2005-03-06.tar.gz will build just fine. But later it 
wont work, probably because its not the right kernel :)

I have tried to rewrite the Makefile and link files where it expect them to be. 
Like in /lib/modules/2.6.10-1.770_FC3smp/build/include/asm I tried
to link:

lrwxrwxrwx  1 root    26 Mar 31 06:57 mach_apicdef.h -> 
mach-bigsmp/mach_apicdef.h
lrwxrwxrwx  1 root    25 Mar 31 06:58 mach_mpspec.h -> 
mach-bigsmp/mach_mpspec.h

but it didnt help either :(

Help?
