Problem with Ubuntu 10.04

by Spongebob25 ? Sun Jan 17, 2010 11:54 pm

I upgraded to Ubuntu 10.04 Alpha 2 and now I get an error when trying to run the f@h client.

Your not the first to have issues with Ubuntu 10.04.

viewtopic.php?f=55&t=12824

Did you tell the Ubuntu developers there's an issue with 10.04 and F@H?

Nope. Don't know where to go to get help.

Here is the error so you don't have to read the log.

fah6: relocation error: /lib/libnss_files.so.2: symbol __rawmemchr, version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference

Do you have this set up as a chron job, or perhaps installed through an Ubuntu specific script like Origami? Otherwise, I've not heard before that F@H calls libraries from the host system. I've always assumed the F@H client, mpiexec and cores were all self contained and only called each others' sub-routines.

Hopefully you have a Launchpad account since you are beta testing. Your problem with 10.04 needs to be reported at:

https://launchpad.net/ubuntu

There are a couple of places to go for help with Ubuntu as relates to F@H. Perhaps you could inquire through these channels as well.

The relocation error has to do with the glibc 2.11.1 build that Ubuntu 10.04 comes with. I built 2.11.1 for my Slackware64 systems and have not had any issues folding with this version libc. I also was able to get my glibc build to install on Ubuntu 10.04 Alpha 2 and the folding client works without issues now.

True, though note that most likely one will need to change every* "lib64" reference
to "lib" as x64 Debian keeps 64-bit libs in /lib/ (Ubuntu guys -- please confirm).

I'll be happy to make sure it runs flawlessly on Ubuntu if someone:
a) provides me a way to get into a machine (ssh) (less burden?) or
b) is willing to do several "run these commands and e-mail me the output" iterations

Thanks,
tear

*) target directory name is actually arbitrary but methinks it's better to keep things simple

EDIT: Jun 19: Following workaround is deprecated. Please use the one from hus -- Ubuntu instructions are located there.

Okay, Ubuntu 10.04 is not exactly the same deal as Fedora 11+. Actually it is, but issue can't be worked
around the same way due to fact of Ubuntu libc.so.6 being stripped more (no STRTAB section).

Fedora 11/12 users please see this post for instructions.

Do the following:

Code: Select all: ## make sure wget, bash, binutils, bc and awk are installed ## log in the user that runs FAH client; this is a MUST, DO NOT USE SUDO cd ~ wget http://darkswarm.org/whosyerdaddy-0.6.sh chmod +x whosyerdaddy-0.6.sh cp -a /lib ~/lib64-fah cd ~/lib64-fah ~/whosyerdaddy-0.6.sh

EDIT, May 14: DO NOT use sudo with any of commands above (unless you run the client as root but that would be... silly);
using sudo (root access) in described procedure but running client as non-root user will get you nowhere -- client will not work;
again, this procedure MUST be performed by the same user that normally runs the client.

Now that you're set up, prepend your client command line with LD_LIBRARY_PATH=~/lib64-fah every time you start the client, for instance

Code: Select all: LD_LIBRARY_PATH=~/lib64-fah ./fah6 -smp 2 -verbosity 9

Reference output follows:

Re: Problem with Ubuntu 10.04

I just installed Ubuntu 10.04rc, used the "whosyerdaddy" with the following results:

Code: Select all: hrsetrdr@asrock3:~/lib64-fah$ ~/whosyerdaddy-0.5.sh whosyerdaddy 0.5, a workaround for broken Folding@Home client 6.29 binaries Copyright (c) 2010 by Kris Rusocki Licensed under GPLv2 WARNING: no STRTAB, going with 0x30 offset %-| and single-page size.

I still get the following error:

Code: Select all: fah6: relocation error: /lib/libnss_files.so.2: symbol __rawmemchr, version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference

...not sure where to take it from here.

Hey hrsetrdr, thanks for the report.

Geez. That seems to be significant difference for a transition from beta to rc (can you say code freeze?).

Can you tell me what "sudo dpkg -s libc6 | grep Version" returns?

I'll take a look at it once I'm done with my (long overdue) dinner.

Thanks!

Duh. Silly me. These messages may also indicate you've already run the script.

To be on a safe side, can you please remove ~/lib64-fah directory (with "rm -fr ~/lib64-fah"),
start from scratch and see if you still get same output?

I've updated glibc to 2.11.1-0ubuntu7 and am _not_ geting these messages.

Thanks,
tear

Now that you're set up, prepend your client command line with LD_LIBRARY_PATH=~/lib64-fah every time you start the client, for instance:
Code: Select all
LD_LIBRARY_PATH=~/lib64-fah ./fah6 -smp 2 -verbosity 9

Worked for me on ubuntu 10.04RC. We'll see what happens after the first WU is completed.

Re: Problem with Ubuntu 10.04

Thank you alot for this fix, tear. I updated my dedicated folder/server from 9.10 to the new LTS an hour ago, not knowing that there's a glitch in glibc linkage. After successfully applying your work-around it's running full blast now again, thanks to you. My system was missing bc though, dunno if that is common. Maybe add it to the "Make sure..." line?!

With you it's always a pleasure

Re bc
Weird... so it seems either bc is not installed (by default) with server LTS
or there was general change between beta and release versions (honestly,
I don't feel like investigating this:)

Let me add some sanity checks for pre-requisites. 0.6 is in the works.

Thanks for feedback!
