Hi,
I seem to have some problems with the application "vcr" that uses
libaviplay for encoding to DivX. The problem is an "Illagal instruction"
that I get every tim the app is run. The system what I use (an VIA Epia
800MHz) does not seem to have the needed SSE/SSE2 extensions, according to
/proc/cpuinfo:
vendor_id : CentaurHauls
cpu family : 6
model : 7
model name : VIA Ezra
stepping : 8
cpu MHz : 800.047
cache size : 64 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu de tsc msr cx8 mtrr pge mmx 3dnow
bogomips : 1595.80
The kernel is 2.4.19 and it is compiled as "CyrixIII/VIA-C3/VIA-C5".
The system is a nice little Mini-ITX form factor motherboard, and just
suitable for a PVR system.
I have avifile 0.7, which packs itself up in the dir "avifile0.7-0.7.16".
I built a Debian package using fakeroot, and used these switches to
configure:
./configure --disable-x86opt --enable-quiet --enable-lame-bin
--disable-dependency-tracking --prefix /usr
The "--disable-x86opt" is supposed to disable SSE/SSE2, but that does not
seem to be the case. I assume that it is ignored and that cpudetect.c
fails somehow
Running "vcr" gives me this SIGILL:
(gdb) where

from /usr/lib/libaviplay-0.7.so.0
This is all I seem to get out of it. Is there anything I could do to make
sure SSE/SSE2 is disabled? Is there any more info I could provide?
Kind regards,
Jan Ekholm
