I have a 64-bit (amd64 a.k.a. x86_64) Debian or Ubuntu installation. I need to run 32-bit (i386/i686) programs occasionally, or to compile programs for a 32-bit system. How can I do this with a minimum of fuss?
Bonus: what if I want to run or test with an older or newer release of the distributi...
@slm I did vote after you did but it is not actually off topic or SPAM. It's just asked by a troll so I thought flagging for mod attention makes more sense.
Unless you are thinking of wheezy, wheezy uses multiarch, so it is more straightforward. I think I did edit a answer by @slm which was related to this. but might not be easy to find.
Since Ubuntu 11.04 (natty) and Debian 7.0 (wheezy) introduced multiarch support, 32-bit and 64-bit libraries can coexist on one system. To install a 32-bit library libXX, first add the 23bit architecture to your system:
For Ubuntu:
sudo dpkg --foreign-architecture i386
And for Debian:
sudo d...
I want to enable extra architecture (of 32-bit) in my 64 bit machine . I did dpkg --print-architecture to know the already known architecture i.e.amd64 . After that I did dpkg --print--foreign-architectures and got the result as i386(I want to enable this) . But when i typed dpkg --add-architectu...
While answering a question, op says that there is no /etc/dpkg/dpkg.cfg.d/architectures file.But instead of this he had the file /etc/dpkg/dpkg.cfg.d/multiarch
http://unix.stackexchange.com/questions/105778/have-you-seen-this-cat considering this question is the only which use the tag [tag:amusements] can we consider this tag is a meta tag ?
@Kiwy no, a meta tag is not one that is not often used, it is a tag that is meaningless unless combined with another tag. Amusements seems perfectly reasonable to me.
@terdon what is or is not amusing is really subjective no ? For example this morning someone ask something to install windows 95 on dosbox on rasbian I would consider that as amusements
There is no /etc/dpkg/dpkg.cfg.d/architectures file in Ubuntu 12.04.So the below command will works,
echo "foreign-architecture i386" > /etc/dpkg/dpkg.cfg.d/multiarch
OR
sudo dpkg --foreign-architecture i386
The debian howto says
Note that the Ubuntu dpkg in natty (1.16.0~ubuntu7 (reports 1.15.8.10)), oneiric and precise (1.16.1.2ubuntu7) uses a different syntax:
so maybe either of these two commands will work for natty, oneiric and precise.
@AmithKK bad assumption, the two sites are VERY different. Plus, we already get messages in our inboxes, we really really don't need candidates coming in to random chat rooms and spamming us
Yes damn it. Twice or more times. Seriously, don't go spamming random chat rooms. Plus, most of us here have been using Linux since way before Ubuntu and have a very strong dislike for UBuntu
Not even @Braiam uses Ubuntu as his main OS and he's actually a candidate! :)
ALthough, I have to admit I did love Ubuntu when it first came out.
Ubuntu still have a really impressive hardware support and the things I hate the most about it is the fact they develop theire own envirronement instead of using the good project (wayland to noame only one)
Can't blame Ubuntu for that, that's all Debian. By the way, try using RPM for a while and then complain about .deb :) (damn I hope @slm didn't see that)
@AmithKK you forget that we've all been 13. What, do you think you'll magically forget how to swear when you reach 18?
Nah, seriously, profanity should be avoided on the main site, and we should not be using it excessively or anything but there is no rule against it in chat. This has also been discussed on meta.
Oh, and using it against someone is a definite no no.
I started out in Serverfault and that's where I still spend most of my time. Here I get to dig into the innards of unix in a way I don't do very often professionally anymore.
@terdon I don't understand how anyone could want to spend their days clicking in dialog boxes...
Of course, I'm currently spending my time having my phone placed on the spacebar in order to answer "y" on fsck because someone used the commandline without thinking first.
See, resizing the volume smaller without doing resize2fs first is a really bad idea.
I'm looking for a self contained application that would assist in teaching basic programming concepts to 4th graders (9-10 years old).
NOTE: I'm looking for an actual application that would help in teaching them loops, conditional logic, etc. in a fun and interactive way. I'm a computer enginee...
@terdon Yeah. I have worked as a sysadmin for almost two decades and this is the first time someone's broken a file system this hard in so short a time, excepting cases with actual hardware failure...
@slm looks fine to me. Damn Gilles is a mod there too?
@JennyD I just hate situations where something has been running for too long to risk stopping and redoing in a more efficient way. I like the phone hack though :)
@slm I wonder if actual physical electric stuff would work. I had lots of fun as a teenager with some thingy that let you connect circuits, and you were supposed to make a particular subset of lamps light up. It definitely helped me think in terms of if/then/else.
@Kiwy It depends on the problem. In this case, I've got a system where the superblock thinks the file system is 600 gig while the underlying volume group is far less. This makes fsck want to check each single missing inode, and it considers that the error condition is so severe that it doesn't allow you to automate the check.
in my desperate quest to get ride of useless tag what do you think of application it's often use for the tag software-rec and it more often is use for application that does not yes have a tag, or just about how to install an app, does this tag not a bit too vague ?
Yes as one of the answerers, I thought it was incorrect of Jllarge to pressure you into (unaccepting my answer) vs. accepting his. Not from the perspective that mine was right or his was right but that as the OP it's your prerogative. You even said to him in comments on his answer why you chose m...
@Braiam - really? 8-) this was a case where there are so many choices that I wanted input before proceeding, otherwise I would've tried the 3-4 choices, asked the Q and then written the dissertation answer my self 8-)
@slm congrats \o/ (it's nice to see that you do not rule on every StackExchange website)
Also after [tag:application] that should be deleted, I find the tag [tag:anaconda] I found those three product named anaconda but I really don't know what is what :
Joking aside, when I first joined the site I was too intimidated by the level of knowledge displayed here. What the hell do I know, I'm a biologist for heaven's sake! But then I saw that people were friendly, I learned a lot and here I am a year later one of the top 10 users on the site.
@terdon One of the things that's appealing here is that there's such a broad range of questions. It's everything from basic unix knowledge to really deep questions.
I started out on serverfault. Over there, neither the very newbie questions nor the really deep ones are appropriate. I still spend most of my time there but I do want these types of questions too.
@terdon Yes and no, it depends on what type of question. If it's more of a programming issue then it doesn't belong there; if it affects how to manage the system then it does belong there.
@Kiwy Anaconda is the application that runs during the installation of any redhat distro. It's written in Python and meanders it's way through the process hence the name
Kudzu is the application that does the autodetection of hardware from boot to boot.
kickstart is the application that takes the choices from a .cfg file and provides them as answers to Anaconda.
I have an amd64 installation of Debian 6.0 (Squeeze), where I need to install a 32 bit version of the libpcap0.8.
I have done an apt-get install ia32-libs which gets me a 32 bit libc and a few other things, but now I need another specific 32 bit package.
What do I have to do ?
(EDIT: the sugg...
@slm I am personally, but I'd skip rather than vote to keep closed. The OP{ has not been seen in an hour so let's give them time to answer the schroot thing
@FaheemMitha I really really object to that mentality. One of the best things about Linux for me was that it did not badger me update all the time. If it ain't broke, don't fix it.
Anyway, the OP could have any number of valid reasons to keep an older OS
I see no reason to update my 5 year old machine that is not connected to the internet and only serves files to my LAN. Why should I spend a weekend re tweaking everything just to have a newer version?
@Braiam @Kiwy security is only an issue for sensitive data. I don't care if there are security holes in my system if I have nothing sensitive there or if it not connected to the internet.
Plus, there is a big difference between security updates and a full scale OS upgrade
@terdon In practice this usually is the best thing to do. Speaking as someone who is not overly fond of updating. Debian releases last like 2 years plus, so it is not like it is a continuous upgrade treadmill.
@terdon security update vs upgrade I agree but still having a non up to date system is a problem even if you have nothing to hide do yhou like that your own server get use by other to send spam for example ?
The usual reason for upgrading is that the software available for the release is increasingly out of date. Again, speaking as someone who doesn't exactly care about the bleeding edge.
Of course, security upgrades will eventually end for squeeze too.
@FaheemMitha I mean that I can have a simple file server on my LAN that has no internet access and is only accessible through the LAN. It could even be on a different subnet or whatever.
@terdon Well, if the poster has special needs/desires, he will presumably comment. Nobody is in a position to dictate what he does, it is merely a suggestion.
@Braiam only if you are willing to upgrade and that is not always an option in professinal settings where various users need older versions or where the machine can't be taken offline or whatever
@FaheemMitha I know, I know, it's just a pet peeve of mine. I get tired of answering "upgrade broke my system" questions where the OP had no reason to upgrade in the first place. A 4 year old system is a different matter, agreed.
It actually took me a while to upgrade from squeeze to wheezy, because I had mostly backported things i needed, like gcc 4.7. also, i was suffering from computer administration enuii.
In your specific case it does not matter but in case you get several interface, and also if you use conditional configuration the order can became important.
For example in this case
iface eth0 inet static
address 88.191.xxx.zzz
netmask 255.255.255.255
broadcast 88.191.xxx.zzz
#dns-nameserve...
@Kiwy that's my upvote there. I think it is fine, it could be improved if you actually explain when the order could be relevant. Is it only in the case of post-up and post-down?
@Kiwy I think that's a fine example (and a perfectly good answer, hence the upvote). All I am saying is that to improve it you might try for the general case, as in "these options depend on the order, all others don't". But it is not that needed IMO
