Package: libcv2.1
Version: 2.1.0-3
Severity: normal
Hi,
the version of libcv2.1 that comes with Debian stable should work on any
i386 hardware, but does not. On the Vortex86DX (i586-compatible), it breaks
due to the presence of (at least) a cmovg instruction (i686+).
Program received signal SIGILL, Illegal instruction.
0xb7ef8968 in cvInitImageHeader () from /usr/lib/libcxcore.so.2.1
(gdb) bt
#0 0xb7ef8968 in cvInitImageHeader () from /usr/lib/libcxcore.so.2.1
#1 0xb79f8e61 in CvCapture_FFMPEG::open(char const*) ()
from /usr/lib/libhighgui.so.2.1
#2 0xb79f8fa1 in cvCreateFileCapture_FFMPEG(char const*) ()
from /usr/lib/libhighgui.so.2.1
#3 0xb79e8fa2 in cvCreateFileCapture () from /usr/lib/libhighgui.so.2.1
....
(gdb) x/i 0xb7ef8968
0xb7ef8968 <cvInitImageHeader+552>: cmovg 0x150(%esp),%eax
(gdb)
Regards,
Aymeric
