Sabayon 9 64 bit and glibc

[tekwyzrd]

I installed the most recent boinc alpha build (7.0.30) and and found it won't work. Starting it in konsole I got the following:

BOINC $ ./run_client ./boinc: /usr/lib64/libssl.so.1.0.0: no version information available (required by ./boinc) ./boinc: /usr/lib64/libcurl.so.4: no version information available (required by ./boinc) ./boinc: /usr/lib64/libcrypto.so.1.0.0: no version information available (required by ./boinc) ./boinc: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by ./boinc)

which seems to be telling me it's looking for glibc v2.15.

According to https://www.gnu.org/software/libc/libc.html glibc 2.16 was released 2012-06-30 so I can't help wondering why Sabayon is still using glibc 2.14 which was released 2011-06-07

we prefer to use stable glibc, glibc 2.16 is too new and not stabilized by upstream yet.
From where did you get that boinc executable?

boinc_7.0.30_x86_64-pc-linux-gnu.sh

last version i can use with sabayon is:

Mo 02 Jul 2012 14:13:57 CEST | | Starting BOINC client version 7.0.27 for x86_64-pc-linux-gnu

[lxnay]

Well, they should not have built it against glibc 2.15 in the first place.

Before posting here I filed a report of the problem to the BOINC alpha site. I posted here because It seemed a bit odd that Sabayon is described as "bleeding edge" but still using a version of glibc that's over a year old, especially when you consider that Mint 13 (Maya) and ubuntu 12.04 LTS both use glibc 2.15

I run old Boinc version

This Version works fine.

if you know what you do , you can compile glibc from portage .... I don't konw what will happen.

[tekwyzrd]

I'll probably try to compile from the most recent source with a few select optimizations as I used to do to compensate for the difference between my computer and similar processors running windows.

you are warned.

Glibc is a part of the core-system ... If you don't know how to manage portage utils you may have a broken system

[tekwyzrd]

I was referring to boinc, not glibc. If you compare two identical computers running the standard build of boinc the computer running Linux reports lower benchmarks than the one running Windows. I've been using (-fomit-frame-pointer -funroll-loops -fforce-addr -ffast-math) for years to reduce the difference. I haven't done so recently because I don't plan on using this computer for much longer but while I am I'll keep running BOINC. 7.0.25 is running fine and processing a task for einstein@home as I type this.

Ok.

You can find Boinc-7.0.28 (not .30) here : http://gpo.zugaina.org/sci-misc/boinc/euscan (SVN)

Code: Select all

# layman -a gentoo-zh
# emerge boinc --ask

then

Code: Select all

# equo rescue spmsync

the configure boinc for your user :

Code: Select all

# nano -w /etc/conf.d/boinc

Set work directory and user,group

Code: Select all

RUNTIMEDIR="/your/boinc/work/directory"
USER="<your_user>"
GROUP="<your_favourite_groups" # default "users"
ALLOW_REMOTE_RPC="yes" # or "no"   if you want manage remote Boinc istance


Add your user to boinc group and video group

Code: Select all

# gpasswd -a <your_user> boinc
# gpasswd -a <your_user> video # only if your user isn't


Logout to make change effects
and start Boinc

Code: Select all

# /etc/init.d/boinc start

If it works well you can start boinc at boot

Code: Select all

# rc-update add boinc default

Enjoy

Boinc 7.0.28 run with sabayon glibc

PS :
If you want compile Boinc with special flasg :

Code: Select all

CFLAGS="-O2 -march=native -pipe -fomit-frame-pointer -funroll-loops -fforce-addr -ffast-math" emerge boinc --ask

and if you want a cuda support :

Code: Select all

# CFLASG="<like above>" USE="cuda" emerge boinc --ask

Code: Select all

[edit] if you compile boinc with a special cflags you optimize the client not the aplications sent by projects
