It seems since I upgraded from 4.43 menubar to 5.2.13, I've been getting many a client error in my results. What is a signal 5? What can I do to fix this?

<core_client_version>5.2.13</core_client_version>

(a5 is the altivec-optimized seti client by Rick of MaCNN team http://writhe.org.uk/seti@home/ which had been working fine on 4.43, and still works fine under 5.2.13 on my other machine)

alpha-5 and its kin (alpha-5.2) only work with OS X 10.4. Tiger added a couple functions that we use in quite a few places for speedup purposes.

You'll have to go back to the Panther-specific compile of alpha-4 on the site you linked to, at least until I compile a OS X 10.3.9-compatible binary. It should just be a matter of changing some Xcode settings, but it's midterm season, so some patience is in order.

Thanks, Alex. I'll knock my G5 with Panther back to a4.

I noticed there is a 52-g4 in your directory -- is this stable for a G4 running Tiger?

Yes, it's stable, but I wouldn't count on it being any faster than alpha-5. In fact, there's a good chance that it'll be slower. (This is just a consequence of the speed tweaks between alpha-5 and alpha-5.2.) If I were you, I'd stick to the G4 binary I've linked to from the thread.

Hi Andrew,

Powerbook G4 10.4.5 using 5.2.13 without problems.

Keith.
