[Comment 1 Jakub Moc (RETIRED) 2006-04-09 04:39:52 UTC]

Don't use -march=k6-(whatever), it's known to be broken...

[Comment 2 Rodrigo Severo 2006-04-09 07:47:33 UTC]

I thought this could be a duplicate of Bug #24379.

I tried -mtune=k6 and even tried without any -march, -mcpu or -mtune. I still get exactly the same error. 

What should I do?

[Comment 3 Andrej Kacian (RETIRED) 2006-05-01 15:21:50 UTC]

clamav-0.88.2 is in portage now, does that one work for you?

[Comment 4 Andrej Kacian (RETIRED) 2006-05-01 15:33:47 UTC]

Actually, scratch that - expat-1.95.8 still provides libexpat.so.0. But still, we're going to have to add <dev-libs/expat-2 to RDEPEND.

Disregard this comment please, wrong bug. (I hate the "move to next bug in list after comment" feature.)

[Comment 6 Jürgen Pierau 2006-05-11 06:57:02 UTC]

I got something like that and did a quick gdb run which left me with this:

<snip>
(gdb) run
Starting program: /usr/sbin/clamd
[symbols not found yada yada...]
[Thread debugging using libthread_db enabled]
[New Thread 16384 (LWP 30471)]

Program received signal SIGILL, Illegal instruction.
[Switching to Thread 16384 (LWP 30471)]
0xb7f45ddb in __gmpz_mul_2exp () from /usr/lib/libgmp.so.3
</snip>

So the problem seems to be in libgmp rather than in clamav. Will rebuild libgmp and get back to you.

[Comment 7 Jürgen Pierau 2006-05-11 07:09:00 UTC]

Well, a 

emerge --oneshot -av gmp

fixed the problem for me. No more "Illegal instruction" when starting clamd.

I now run clamd-0.88.2 on a VIA C7 processor.

You are right. It fixed the problem to me too.

Sorry for the bogus bug report.
