server:~ # rcasterisk start
Starting Asterisk startproc:  signal catched /usr/sbin/asterisk: Illegal instruction
======================================================================
According to asterisk mailing lists this is due to wrong architechture.
Building my own RPM with the provided SRPM solves the problem.
The original rpm is probably compiled for i686. 
Tested on AMD K6III+ 
10.0 has the same problem (as well as previous 10.1 betas)
Follows debuging info made with the non working binary.

Comment 1 Michael Gross 2006-02-07 14:52:44 UTC

So the program crashes on an AMD-K6-3? Just to be clear about that.

Comment 2 First Name Last Name 2006-02-07 17:14:37 UTC

Technically speaking, I do not know if it crashes, or if it does not run.
It is an incompatible binary. If you try to run it the error comes instantly.

server:/ # asterisk
Illegal instruction
server:/

If it's the system or asterisk printing that error, it's is beyond my knowledge.
Same problem with beta4 asterisk-1.2.3-2
Compiling myself fom SRPM and problem gone.

Comment 3 Michael Gross 2006-02-07 17:29:12 UTC

Yes this means that the program was compiled for an incompatible architecture and contains a cpu-instruction (opcode) which cannot be understood by the CPU. Of course the program is terminated then.
Let's ask the asterisk maintainer.

Comment 4 Reinhard Max 2006-02-07 18:46:46 UTC

IIRC K6-2 and K6-3 only support a subset of the MMX extension and Asterisk happens to use some of the instructions that are not supported. When recompiling from the source RPM on such a machine, the build system detects the CPU and builds with MMX disabled.

OTOH, I thought I had patched away this autodetection and forced Asterisk to build without MMX in any case. I need to investigate this...

Comment 6 Reinhard Max 2006-02-09 16:20:43 UTC

There are new RPMs under ftp://ftp.suse.com/pub/projects/asterisk/10.1-beta3 . Please try them and let me know if they run out of the box on the K6-3.

Comment 7 First Name Last Name 2006-02-09 17:48:42 UTC

http://ftp.suse.com/pub/projects/asterisk/10.1-beta3/i386/asterisk-1.2.3-3.i586.rpm
runs without glitches.

Was simply solved by disabling mmx?

Comment 8 Reinhard Max 2006-02-10 09:34:05 UTC

No, the modules that have support for MMX (e.g. the GSM codec) had it disabled already.

But Asterisk compiled some source files with -march=i686 when it found to be built on a 686 machine, and that results in binaries that contain instructions which are not available on an i586 CPU. I've removed that check, so that only i586 code is generated, regardless of the CPU we are compiling on.
