**** BEGIN LOGGING AT Tue Nov 15 02:59:57 2011 Nov 15 08:30:20 Hi Nov 15 13:25:07 I do wonder will we have arm64 with multilib for armel/armhf Nov 15 13:25:32 ugh Nov 15 13:25:44 scary thought Nov 15 13:26:39 I have worse one ;) Nov 15 13:26:52 arm64 or arm64sf or arm64hf? Nov 15 13:27:31 i guess that depends what we choose as default for precise Nov 15 13:27:46 and dont expect an arm64 arch at all this release Nov 15 13:27:52 I do not Nov 15 13:27:55 we will likely have 32bit userspace Nov 15 13:28:01 and a 64bit kernel Nov 15 13:28:15 I do not expect arm64 before q/r Nov 15 13:28:18 as of el or hf, we will only decide by feature freeze Nov 15 13:30:08 wait there is a 64bit arm proc? Nov 15 13:30:19 no Nov 15 13:30:23 lilstevie: arm announced it ~2 weeks ago Nov 15 13:30:25 thats what I thought Nov 15 13:30:26 ah Nov 15 13:30:27 thats why we dont care about that arch yet Nov 15 13:30:31 I missed the announcement Nov 15 13:30:33 lilstevie: so far only fpga implementations Nov 15 13:30:35 there will be Nov 15 13:30:44 I see Nov 15 13:30:52 I really want a T3 in my hands Nov 15 13:31:14 * ogra_ just wants a 4U calxeda box Nov 15 13:31:15 the 4+1 concept is rather clever Nov 15 13:31:38 thats just ~300 cores and 300GB RAM Nov 15 13:31:56 lol wow Nov 15 13:32:29 (and 300 SATA ports) Nov 15 13:33:07 thats a lot of drives Nov 15 13:33:17 one per core Nov 15 13:33:26 yeah figured Nov 15 13:33:36 ogra_: but you want some of storage modules in this 4U too? Nov 15 13:33:38 1GB ram 1 SATA per core Nov 15 13:33:57 hrw, i have a spare cabinet, they can go into a second box :P Nov 15 13:34:14 heh Nov 15 13:34:39 hrw, ogra_: I think hard-float will be mandatory for AArch64. So there might just be an aarch64 ABI, which is completely separate from arm*. 32-bit binaries should be able to live under a 64-bit kernel using multiarch. But this is all way in the future Nov 15 13:34:44 I hate messy hacks for kernel drivers :/ Nov 15 13:34:48 with that setup i could make the raspberry pi people happy :) rebuild the whole archive in 1day :) Nov 15 13:35:16 dmart, yeah, and we still dont have hf yet Nov 15 13:35:29 raspberry pi is not armv7? Nov 15 13:35:41 nope Nov 15 13:35:44 v5 afaik Nov 15 13:36:36 ew Nov 15 13:37:17 ogra_: Don't they just use Debian armel for now? Given the limited capabilities of the device, that seems reasonable Nov 15 13:37:49 yes, i hope they do, though there was discussion about fedora as well Nov 15 13:37:59 not sure what they decided on as their default Nov 15 13:38:25 * ogra_ has plenaty of personal flame mails from raspberry people ranting about ubuntu not going back to v5 Nov 15 13:39:31 They should rant at the rpi folks for not choosing a v7 CPU ;) Nov 15 13:39:41 heh, yeah Nov 15 13:40:04 well, i was the one who answered in the bug that asks for supporting the raspberry Nov 15 13:40:35 telling that it would take plenty of resources and that they are free to offer these to canonical for maintining a v5 community port .... Nov 15 13:44:20 pi is armv6 Nov 15 13:44:34 ah Nov 15 13:44:46 well, not much better though ... from an ubuntu POV Nov 15 13:44:52 aye Nov 15 13:45:47 all of those plug devices should use better CPUs really Nov 15 13:46:02 well, the next guruplug will be v7 i heard Nov 15 13:46:30 I still think that the subset of software in Ubuntu which will actually work on this board is also in Debian anyway. The rpi folks could hopefully create suitable Debian images as a community effort on their side Nov 15 13:46:54 thats what i always suggest Nov 15 13:47:26 what happened to the linaro idea to make the archive easily recompilable for lower level arches ? Nov 15 13:47:34 was that dropped ? Nov 15 13:52:03 ogra_: Well, really we want to be able to recompile for _newer_ arches (like armhf). In practice, I think that's being done the old-fashioned way, though we do have quite a lot of cross-buildable packages, and cross-building support is gradually improving with multiarch etc. Linaro focuses on current and future stuff, so pre-v7 not likely ever to be a priority. Nov 15 13:52:41 ah, i thought the idea behind it was to help customers that want pre-v7 Nov 15 13:52:45 hf would be nice Nov 15 13:52:52 hf is in the works Nov 15 13:53:04 autobuilds should start some time this week Nov 15 13:53:17 the question is if it will be ready for precise Nov 15 13:53:21 ogra_: That's not an explicit goal, though mutiarch should make this a bit easier Nov 15 13:53:27 we will decide that by FF Nov 15 13:53:52 fair enough Nov 15 13:54:23 I tried mer on the TF which is hf Nov 15 13:54:30 perf is really orders better Nov 15 13:54:46 ogra_: Presumably, mutiarch should allow armhf and armel binaries to be co-installable? I think that was the idea. We should only rely on this for multiverse etc. though -- the core system should really stick to one ABI, otherwise we end up with a lot of duplicate libraries etc. Nov 15 13:59:49 dmart, i'm not sure4 that works atm Nov 15 14:00:15 infinity could tell though, but iirc there were issues with multiarch last i heard Nov 15 14:00:59 I think it's still a work in progress, but my understanding was that it's _supposed_ to work, at least in the precise timescale. I'm not involved in that though, so I could be wrong Nov 15 14:01:56 well, hf was *supposed* to be ready during the oeniric timeframe :P Nov 15 14:02:02 so much about timeframes :) Nov 15 14:02:15 heh Nov 15 14:02:21 oh, right. I said I could be wrong ;) Nov 15 14:02:51 yeah I thought there was some soft/hard abi incompatibilities Nov 15 14:03:00 and that it was all or nothing Nov 15 14:03:13 well, multiarch was supposed to solve it Nov 15 14:03:23 but rather on a theoretical level yet Nov 15 14:04:36 multiarch works, but there is a snatch in that both armel and armhf use /lib/ld-linux.so.3 as dynamic linker Nov 15 14:04:51 but people (eg infinity and sledge) are fixing that Nov 15 14:04:52 yeah, that was it Nov 15 14:05:24 suihkulokki, well, not sure ... he might skip that part to finally get the pressure off to actually *have* hf at all Nov 15 14:06:00 it has to happen real soon, else we'll not be able to make precise Nov 15 14:07:47 Ah, I remember that one Nov 15 14:08:21 Changing the ld.so path does require absolutely everything to get rebuilt though :( Nov 15 14:08:32 right Nov 15 14:08:47 naah, that's just buildd time Nov 15 14:08:55 which we dont have at all Nov 15 14:09:22 given that we put double load on them already Nov 15 14:10:16 I should set my trimslice up to do more building for me Nov 15 14:10:33 heh Nov 15 14:11:42 Actually, we just need a tool to poke something else in the DT_INTERP field of existing binaries... Nov 15 14:58:22 lilstevie: got a sec? Nov 15 14:58:44 shadeslayer: kinda Nov 15 14:59:08 lilstevie: ok, I was trying to boot ubuntu via the chroot method now we have a local exploit thanks to you guys Nov 15 14:59:24 ( thanks a ton for that! ) Nov 15 14:59:55 The problem is that the script has a modprobe ext2 command which is failing Nov 15 15:00:11 modprobe: chdir(/lib/modules): No such file or directory << Any ideas where I can find that? Nov 15 15:01:04 I have no idea about chroot Nov 15 15:01:19 alright, thanks anyways :) Nov 15 15:01:24 I don't like/support/work on or condone the use of chrooted environments Nov 15 15:01:25 :p Nov 15 15:03:29 lilstevie: yeah, well, seeing how I can't flash ubuntu natively yet, this is a workaround ;) Nov 15 15:03:46 heh yeah Nov 15 15:03:56 well you could loop mount :p Nov 15 15:04:22 yeah, I'll have a go at that after dinner Nov 15 15:05:10 I also get : chroot: can't execute '/bin/bash': No such file or directory .. weird Nov 15 15:18:03 hah Nov 15 15:18:13 lilstevie: I don't think the stock kernel has loopback support Nov 15 15:20:44 shadeslayer: you can flash a custom kernel though Nov 15 15:21:12 lilstevie: uh, custom kernel or custom ROM? Nov 15 15:21:26 I've never flashed a custom kernel before ... Nov 15 15:23:06 both Nov 15 15:23:13 key is don't flash both at once Nov 15 15:23:25 flashing both at once == brickable chance Nov 15 15:23:56 ah ok, Is there a well documented wiki or something for this out there? I'll read up on it before I do something nasty Nov 15 15:24:31 not really Nov 15 15:24:35 these are the nasty hacks Nov 15 15:24:41 hehe ^^ Nov 15 15:24:57 I am working on building an apk to do the nasty hacks in a sane way Nov 15 15:25:12 lilstevie: any progress on the miniloader situation that you guys had a couple of weeks earlier? Nov 15 15:25:23 nop Nov 15 15:25:41 oh fooey ... so no native ubuntu for the next couple of weeks then Nov 15 15:27:55 lilstevie: so whats this new APK that you're making? :) Nov 15 15:28:13 using some really ugly hacks to install ubuntu Nov 15 15:28:49 natively or chroot? Nov 15 15:30:54 natively Nov 15 15:30:59 * lilstevie would never chroot Nov 15 15:31:05 zomg Nov 15 15:31:08 lilstevie: <3 Nov 15 15:31:23 alright then, I'll wait it out for your app Nov 15 18:06:29 hello Nov 15 18:07:53 join now Nov 15 18:08:06 alo Nov 15 18:10:45 alo Nov 15 18:10:58 pnphi: who are you talking to? Nov 15 18:10:59 hi all Nov 15 18:11:19 please..help me.. Nov 15 18:11:20 :) Nov 15 18:11:32 how to building image ubuntu for ARM,step by step. Nov 15 18:11:58 pnphi: what is your target device? Nov 15 18:12:09 Beagleboard Nov 15 18:12:34 pnphi: Did you try preinstalled images? Nov 15 18:13:18 pnphi: Did you check https://wiki.ubuntu.com/ARM/Beagle ? Nov 15 18:13:57 the link...this is install ubuntu on ARM Nov 15 18:14:35 Exactly what the beagleboard is running. Nov 15 18:14:43 how to create image ubuntu on ARM Nov 15 18:15:06 Download the preinstalled image, flash to SD, boot. Nov 15 18:15:18 What exactly are you trying to do? Nov 15 18:15:35 i can install ubuntu on ARM Nov 15 18:15:48 but i want to ... how create this image Nov 15 18:17:02 i'm know english very bad....i'm come from Vietnamess Nov 15 18:17:04 infinity: Care to explain how we build images? Nov 15 18:18:05 step by step ... create image ubuntu for ARM Nov 15 18:19:15 pnphi: Unfortunately, other team members are very busy with getting 12.04 started, but the short answer is we have a series of scripts that build the images from scratch on an arm platform, then bundle them up into a single pre-installed image for users. I don't have the specifics on the process. Nov 15 18:20:23 If you are looking to create your own image, I would recommend starting with our ubuntu-core images on http://cdimage.ubuntu.com (see https://wiki.ubuntu.com/Core for more info). Nov 15 18:20:45 oh i understan Nov 15 18:21:07 It is essentially a stripped down chroot envirnment that you can install packages into. It has just enough functionality to do apt-get install. Nov 15 18:21:12 pnphi: It looks like you need just to install it, not to build. Am i right? Nov 15 18:22:20 no no...i need how to create this image...i can install this image Nov 15 18:23:55 from ubuntu source...how to create image for ARM... ? Nov 15 18:26:33 From source? You mean recompile each package and build an image from there? Way beyond the scope of this channel. Nov 15 18:27:13 the same Nov 15 18:37:41 i'm mad with this problem Nov 15 18:38:40 join nơ Nov 15 18:38:44 join now Nov 15 18:39:06 Why do you want to create an image from source? Why not just use our images? Nov 15 18:40:02 my graduation project Nov 15 18:41:06 I do not have to create images for business Nov 15 18:42:25 In that case, part of your education should be learning the steps needed to build packages, and with those packages, build an image. Asking someone for these steps doesn't teach you how to do it. There are plenty of books and reading material online that describe how to create debian/ubuntu packages, images, etc. I recommend more study time. Nov 15 18:43:32 in my school, teachers did not teach me, so I came here Nov 15 18:44:05 What type of class? Document writing or programming. If programming, they should fire your teachers. Nov 15 18:44:39 My school is not good Nov 15 18:44:44 so i come here Nov 15 18:45:07 i can create a package Nov 15 18:45:15 i can create a package for ARM Nov 15 18:47:20 my school don't has any teacher who pro about this problem Nov 15 18:47:48 so i come here...i need the help Nov 15 18:49:40 I write not good english so please ignore Nov 15 18:49:45 Unfortunately, we really do not have the time/resources to help with that level of complexity on this channel. Which is why I recommend searching the internet for documentation (I know there is good material out there, I just don't have any links handy). Nov 15 18:50:19 can you give me the Document ? ? Nov 15 18:50:30 i need only Nov 15 18:50:51 please Nov 15 18:51:01 there is no single document for this Nov 15 18:51:32 if you really want to build ubuntu from source i would start with learning how to set up a buildd ... Nov 15 18:51:40 i know...this is very large Nov 15 18:51:43 You can start here: https://www.google.com/search?client=ubuntu&channel=fs&q=ubuntu+image+building&ie=utf-8&oe=utf-8 Nov 15 18:51:56 Tons of links. Nov 15 18:52:02 once you have the archive compiled (in a few months) you can read up about live-build and debian-cd Nov 15 18:52:05 oh my god Nov 15 18:52:31 i need specific....please Nov 15 18:53:04 We have over a dozen systems building packages constantly. Which is why I said this is no easy undertaking. Nov 15 18:54:06 i know Nov 15 18:54:15 several packages take hours/days to build on better hardware than a beagleboard. Nov 15 18:54:22 if you really want to build from scratch i would recommend another distro Nov 15 18:54:34 ubuntu is not designed for this Nov 15 18:54:42 or how about: https://launchpad.net/project-rootstock Nov 15 18:54:44 The kernel is around 12 hours to build. LibreOffice is 3 days. Nov 15 18:54:45 have a look at angstrom Nov 15 18:55:01 gildean, that doesnt compile any packages Nov 15 18:55:07 what is distro ? Nov 15 18:55:11 (and is unmaintained) Nov 15 18:55:22 nope, i didn't read enough to know that's necessary Nov 15 18:55:48 pnphi, ubuntu is a distro (distribution) of software ... Nov 15 18:56:25 angstrom is a distro that you can easily build from source and it works fine on the beagleboard Nov 15 18:57:16 but my project need ubuntu for ARM on beagle Nov 15 18:57:27 http://www.angstrom-distribution.org/ Nov 15 18:59:26 i will die..... Nov 15 18:59:29 i wonder wether the å is supposed to be pronounced as an o or as an a in that name Nov 15 19:00:45 eeengstrreeem :) Nov 15 19:01:39 ongström Nov 15 19:02:01 it think its more like Ä Nov 15 19:02:23 if it's supposed to be a swedish o, then it's more like an o Nov 15 19:04:05 join now Nov 15 19:06:06 good for you Nov 15 19:06:17 huhu not good Nov 15 19:07:30 i don't know ...i begin where ? ? Nov 15 19:08:37 imho ogras idea about switching your project to ångström makes a lot of sense Nov 15 19:09:15 http://www.angstrom-distribution.org/building-angstrom Nov 15 19:11:51 please sent for me any document about how to create image ubuntu for ARM Nov 15 19:11:58 thank you so much Nov 15 19:12:00 thanks all Nov 15 19:14:22 if you read any of the answers before, it was clearly stated that building everything from scratch with ubuntu is a huge undertaking Nov 15 19:14:37 especially if you're doing it alone Nov 15 19:14:42 on a beagle Nov 15 19:14:54 on a single beagle Nov 15 19:14:59 right Nov 15 19:15:17 i have time Nov 15 19:15:28 how long ? Nov 15 19:15:39 i have 7 mouth Nov 15 19:15:44 or more Nov 15 19:16:11 i have 7 mounths Nov 15 19:16:11 or more Nov 15 19:16:48 and my group have 2 members Nov 15 19:16:56 and 2 teachers Nov 15 19:17:46 do you really want to build *everything* from scratch? Nov 15 19:18:16 i mean, ubuntu is basically the distro that was made so you wouldn't have to build anything Nov 15 19:18:51 yes,,i want from source of ubuntu ...so i will create image for ARM Nov 15 19:19:24 yes, but you can create an image without building any packages? Nov 15 19:19:53 if you want to build everything, distros like gentoo or ångström would fit your need much better Nov 15 19:20:21 i understand Nov 15 19:21:19 maybe...this problem is very hard for me Nov 15 19:21:35 at what level? Nov 15 19:22:09 i don't understand ? Nov 15 19:22:43 this is hard because i don't know beging at where Nov 15 19:23:49 learn about ho to set up a buildd Nov 15 19:23:53 *how Nov 15 19:24:16 step by step ? ? Nov 15 19:24:25 can you help me ? Nov 15 19:24:28 no Nov 15 19:24:32 we dont do such stuff Nov 15 19:24:44 we use the existing infrastructure of ubuntu Nov 15 19:25:11 we upload source packages to launchpad where a buildd builds them Nov 15 19:25:26 clearer? ? Nov 15 19:25:35 if you want to recompile everything from source setting up a buildd is your first setp you need to so Nov 15 19:25:37 *do Nov 15 19:26:03 find documentation on the internet about how to set up a buildd Nov 15 19:26:26 ok Nov 15 19:26:35 and what else ? Nov 15 19:26:48 well, that will keep you busys for a few months Nov 15 19:27:01 no problem Nov 15 19:27:28 if you have set up the buildd you take the ubuntu source packages from ports.ubuntu.com and upload them to your buildd Nov 15 19:27:57 since the only b uildd hardware you have currently is a beaglebaord that will take very very long Nov 15 19:28:19 oh my go Nov 15 19:28:21 god Nov 15 19:28:50 once you have done this, you can read about how to use live-build which is what we use to create a root filesystem from the .deb packages Nov 15 19:29:07 can you share your document for me ? Nov 15 19:29:15 there is no document Nov 15 19:29:22 search on google Nov 15 19:29:36 ok Nov 15 19:29:48 learn about buildds first Nov 15 19:29:55 set one up on your beagle Nov 15 19:30:01 upload the packages Nov 15 19:30:12 if you are done, feel free to come back Nov 15 19:30:38 ok Nov 15 19:31:07 oh i have a ques... Nov 15 19:31:37 apt-get source -d package ... i will have a source package Nov 15 19:31:46 yes Nov 15 19:32:06 where is dep of pack ? Nov 15 19:32:20 dependency Nov 15 19:32:36 is there a bug# for chromium-browser not building on arm? Nov 15 19:32:39 where is dependency of package ? Nov 15 19:32:58 suihkulokki, ask micahg in #ubuntu-devel or -desktop Nov 15 19:33:06 he maintains it and should know about it Nov 15 19:33:43 suihkulokki: http://qa.ubuntuwire.com/ftbfs/ doesn't show any bugs tagged FTBFS. Nov 15 19:33:53 pnphi_, probably you should first read the debian new maintainer guide (google it), it will teach you about how packages work Nov 15 19:34:11 infinity, it failed since two releases or so Nov 15 19:34:21 if tehre is a bug its very old Nov 15 19:34:32 ok Nov 15 19:34:54 ogra_: Sure, but if it's correctly tagged, the scripts will pick it up. Or, so I understand it anyway. Nov 15 19:35:08 ah, well ... Nov 15 19:35:15 i doubt its tagged anyhow :P Nov 15 19:35:29 * suihkulokki grunts Nov 15 19:35:47 but micah knows about the issues with this package and seeks help Nov 15 19:36:47 Building the Ubuntu BeagleBoard Kernel Nov 15 19:48:08 thank you so much Nov 15 19:48:38 i go to sleep...in VietNam,,,now 2h48m AM Nov 15 19:49:27 bye all Nov 15 19:49:35 have a good day Nov 15 19:49:49 thanks all Nov 15 21:13:42 apachelogger: Did you have problem with 2.6.35 kernel booting with u-boot when you was working on it for the N900? Nov 15 21:17:40 I just tried 3.1.0-2 and it behaves as other: just shuts down after startup without showing anything. I remember you've said something about initramfs, but the 2.6.35 boots with just mkimage and none of the other kernels I've tried do. **** ENDING LOGGING AT Wed Nov 16 02:59:57 2011
