CentOS 5 :: Check If Current CentOs Is 32bit Or 64bit?
Dec 26, 2010
I have got an Notebook whose CPU is 64bit.The Notebook has an CentOS installation. Now I want to find out if this CentOS is 32bit or 64bit.How can I check this?
uname -a
gives something with ....i686 i686 i386...."
What does that mean?Does that refer to the hardware or the CentOS OS? An 32bit CentOS can be installed on a 64bit hardware!I am interested in the OS capability not of the hardware!
Use python as example, I have 64bit python 2.4.3 yet I can't found rpm for 32bit one so I try to build it.Use default make or make --enable-readline is ok, python make cannot use CFLAGS, can use OPT and LDFLAGS to add -m32, yetit seems can only search for 64bit lib, or else crush.[Moderator edit: Moved from CentOS-4 to CentOS-5 forum.]
(Second Try) I installed CentOS 5.5 from CDs 32 bit, everything works fine. I then re-install, but this time 64 bit, everything else is the same, I use all of the same options. This time though it sees the network card, and allows me to configure it and activate it. It will not connect outside of it's self, IE it can ping it's self, but nothing else. Go back to 32 bit, and zero problems, try 64 again, no network. Each time I do full installs with partition formatting etc. In case it makes hill-o-beans difference, Intel P4, 2.66 Ghz. 2.0 GB RAM MSi Motherboard.
I have installed centos 5 64 bit in my machine but all the dependencies like php, httpd, glibc, gcc, gd, openssl and others are 32 bit, I need them to be updated to 64 bit.
I've been trying to compile a small program on my 64bit Centos 5.3 but I need to compile it in 32bit mode. I've tried editing the make file and changing CC=gcc to CC='gcc -m32" and that doesn't work. I have also tried to use "make CC='gcc -m32' and that doesn't work either. It wont compile. Do I need to install something with yum to get 32bit compiler to work?
I have searched the whole google but did not find anything. I am trying to install a game server using hldsupdatetool.bin which can be found here, [URL]. Unfortunately it can only run on 32bit Operating Systems. I need it to run on 64bit. What do I need to install? Please be specific since I am really new to linux. Please tell me what I exactly have to type in the command prompt.
I have a system with a missing or damaged kernel and I need to reinstall some software to fix it (see this thread for reference removed xen and kernel is gone). I feel fairly certain I can fix my system with the info in that thread however I don't know if this was a 32bit or 64bit system. How can I tell after using the dvd and linux rescue or does it even matter?

Looking for moral support and guidance. Currently have 13.1 running nicely with the following partitions:
/swap / /home /var /usr/local /notlinux (my name for a storage partition when I want to start all over again)
I have decided to tinker with Slack64-current with multilibs. My intent is to shrink /notlinux an add a new partition for 64's / . Then dual boot the system.
/swap and /usr/local
I see no problem with mounting these partitions in Slack64. I would have two 'tgz' directories [ tgz & tgz64 ] in /usr/local where I would seperate SBo packages (for my benefit). Don't know what having separate /tmp directories would have on sbopkg but that's not a material issue. confirm I can share these partitions.
/home
99 & 44/100 % sure if I changed/added my name from 'dad' to 'dad64' it would not be a problem sharing the /home directory. But what about keeping the same name/uid#, would things get fubared when I jump back and forth between 13.1 and current-64. Comments?
/var
Think I might be getting into trouble here. Suspect pkgtool, installpkg, upgradepkg ... would all continue to work because /var/log/packages would actually have different names [_64] for the 'same' package. At a minimum I want to share the mysql database so might have to create this as its own partition. Other than it would be a mess reading log file would sharing this directory be a major issue.
I am trying to install ffmpeg-php on a centos 5.6 32bit. First I installed php-devel,yum install php-devel. I downloaded the ffmpeg-php from here to /usr/local/src by this commands;
I have 2 older 32 bit programs that I have to run in Centos 64bit. I have seen that in Centos-64-bit there are both 64-bit libraries than 32-bit These programs seems to work properly but is it necessary to do anything else?
I have installed Citrix Xen-Server on my server and managed to install Windows 2003 R2 Server successfully.I also installed CentOS 5.3. The installation went fine, however, I cannot get Gnome or KDE going. I only have the text interface.
I have a server with 12 Gig or ram in it (has per bios detection). Free and meminfo agree. [root@virtualHost ~]# free total used free shared buffers cached Mem: 7726080 794136 6931944 0 50036 391236 -/+ buffers/cache: 352864 7373216 Swap: 8385888 0 8385888
In my /proc/cpuinfo I can see pae in the flags. None of my domUs are going to need more than 3 GB of ram but I was wondering what is the REAL ammount of RAM accessible to the system. If I run 4 domU at the same time. Around 7 GB or 12 GB?
i upgraded my netbook to slack-current (32bit) and now When booting up dmesg shows these errors:
Code: [ 10.770199] [drm] detected 63M stolen memory, trimming to 32M [ 10.770267] i915 0000:00:02.0: irq 43 for MSI/MSI-X [ 10.770280] [drm] set up 32M of stolen space [ 10.770468] [drm:init_ring_common] *ERROR* render ring head not reset to zero ctl 00000000 head 02001000 tail 00000000 start 02001000

This happened with generic stock kernel and is also happening with 2.6.36.2 zen kernel. Is it something serious? Kde compositing still works, except it locked up few times when i was testing how windows wobble in kde, but not recently.

xap/gnuplot-4.2.6-x86_64-1.txz: Upgraded. x/xterm-255-i486-1.txz: Upgraded. x/xf86-video-nv-2.1.16-i486-1.txz: Upgraded. x/fontconfig-2.8.0-i486-1.txz: Upgraded. And this one was present, but not mentioned: x/xf86-video-geode-2.11.7-i486-1.txz: Upgraded.
I just ordered my new laptop (DLL XPS15) and I'm wondering on whether install a 32 or 64 bit version, I don't know if there's really a big difference between each one of them, I've always used a 32 bit version.
I have a server, running Centos 5 and it is working fine. Now I want to have another server (server2), mirror of my current server (server 1) if any time my (sever 1) stopped responding, (server 2) should start working until I fix server 1.
As i just started to write scripts, i'd obviously like automize some actions, therefor i'd like to check the users system if its 64bit. Is there a function to check this?
were's a good start to get into bash scripting, the files i use as template gave pretty much good info, but yet i have no idea what i'm actualy doing
This is probably a dumb question but I can't find out whether I have a 32 or 64 bit machine. Here's uname -a [Linux Flow 2.6.34.7-56.fc13.i686 #1 SMP Wed Sep 15 03:33:58 UTC 2010 i686 i686 i386 GNU/Linux]
I have a 5 year desktop with 1.5GB RAM and the following specifications. AMD Athlon D400 Single Channel 64bit. Would it be advisable to install the latest version of Ubuntu "Lucid Lynx" 64bit on this pc?
I have downloaded the 64bit version of Ubuntu 10.04. I am currently using 8.10 32bit and I want to clean install 10.04 64bit version. However the one thing that is putting me off is that I have heard if your PC has 1GB of RAM or less then 64bit won't run very good because it uses more RAM than 32bit. (my PC has 1GB) So the question is: Does 64bit use more RAM than 32bit?
I currently have Ubuntu running in 32 bit with pae but I now want to switch to 64 bit. all of my hardware supports it. Is there an easer way to switch without needing to install Ubuntu all over again? It's such a haste to copy all of my files and reinstall programs and there settings manually.
