http://askubuntu.com – my ubuntu version is 12.04, and when cat /proc/version, it shows Linux version 3.2.0-23-generic (buildd@crested) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 Linux yuzhe-HP 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Here it shows the os is x86_64. To install oracle jdk over linux, install package comes with two versions x86 and x64. Which should I choose for a x86_64 system? (HowTos)

Stories similar to is x86_64 a x86 or x64?

I have two Ubuntu-x86_64 systems. One is version 10.04, the other 12.04 and there is a difference in the structure of the lib directories. This doesn't surprise me, but I'm curious if anyone knows why. Is there a good™ reason why?

Background info

I'm currently running CentOS (or Red Hat?).

uname -a gives (I edited out my domain name)

Linux XXXXXXXXX.com 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

cat /etc/issue gives

CentOS release 6.2 (Final) Kernel \r on an \m

and `cat /proc/version' gives

Linux version 2.6.32-71.29.1.el6.x86_64 (mockbuild@c6b5.bsys.dev.centos.org)

Hi guys,

could someone throw some light on the following behaviour of printf (I'll start with info about the system and the tool/shell/interpreter versions)?:

Code: $ uname -a Linux linux-86if.site 3.1.0-1.2-desktop #1 SMP PREEMPT Thu Nov 3 14:45:45 UTC 2011 (187dde0) x86_64 x86_64 x86_64 GNU/Linux

$ bash --version GNU bash, version 4.2.10(1)-release (x86_64-suse-linux-gnu)

Hello,

I am trying to install software on the above system.

I know there are similar questions out there, but I haven't found a solution nor this exact case. The binary was built on Arch Linux using its GCC 4.7. The package works fine on the build system. The commands below were executed on:

Linux vbox-ubuntu 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

The file in question is located here.

Greetings,

System information:

Code: $ uname -a && cat /etc/*release Linux pixel 3.6.10-030610-generic #201212101650 SMP Mon Dec 10 21:51:40 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" NAME="Ubuntu" VERSION="12.04.1 LTS, Precise Pangolin" ID=u

I have a system

lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric

We are automating some deploy scripts which uninstall/install RPMs. I've seen on more than one of our hosts that rpm -qa returns something like:

# rpm -qa | grep tcl tcl-8.5.7-6.el6.x86_64 tcl-8.5.7-6.el6.x86_64 tcl-8.5.7-6.el6.x86_64 tcl-8.5.7-6.el6.x86_64 tcl-8.5.7-6.el6.x86_64 tcl-8.5.7-6.el6.x86_64

How does this happen using rpm -e and rpm -i? And is there a way to prevent this?

I'm running Ubuntu 12.04 on a Toshiba L670-14L

I've tried logging out and shutting down with no improvement, I pressed F7 at shutdown splash and lots of call traces printing but noticed error about cpu.
