You are totally welcome. Though I live in North Carolina, Tempe is almost my second home, I'll be back out there in a few weeks :)

Sure thing. System has 16Gb Ram with almost all of it totally free right now.

Tried the debug-info command but it didn't find anything to install. Looks like the debuginfo repos for centos 6 are not updated yet.. Do I need a version compiled with a -g ?

Well, as I said, I had to upgrade gmp to run Yafu. I'm at gmp-5.0.2. I'm willing to upgrade, not downgrade. The lowest even available to me is 4.3.2. Perhaps Gentoo versioning is slightly different than Fedora versioning? Is it possible for 3.5.2 on Fedora to equal 5.0.2 on Gentoo?


I think that's your gmp version, look for libgmp and see what that is.

find / -name libgmp*

should be in /usr/lib64/

7) Message boards : Number crunching : Comp errors on 1.05 for Gentoo Linux (Message 133)
Posted 5 Sep 2011 by Bok
Post:
3.5.0 is the latest release of gmp available for CentOS6 from the main repos. Whilst I can update to the latest with a build I tend to try and keep to the repos on my database servers (which this is).

I'll see if I can find an update on one of the 3rd party repos like atomic.

p.s. I tried running strace after renaming the file to 'in' but it didn't give anything more than a floating point exception and core dumped.

Anything else to try in the meantime?

Post:
I run CentOS6 on this box. Agree on the library issue, I tried an ldd first as well but with it being dynamic..

If I knew how to put in the arguments I could run strace on it, tried a few things but it's obviously not correct, strace doesn't seem to give too much and fails with -

--- SIGFPE (Floating point exception) @ 0 (0) ---
+++ killed by SIGFPE (core dumped) +++
Floating point exception (core dumped)

but I can't tell whether that's because of the incorrect argument.

As you are exporting the xml stats, I did add them to the Free-DC stats pages, which you can see here.

http://stats.free-dc.org/stats.php?page=proj&proj=num

Was quite a coincidence, as I added them on thursday whilst I was staying out in Tempe, Az just a few blocks down from ASU (Courtyard Marriott on Ash Ave :) )

Back home in NC now though.

Good luck with the project!
