| delinquentme | so beagle boards run ubuntu ... how does one take a beagleboard and begin putting specific code on it? is it a USB connection? | 00:01 |
|---|---|---|
| delinquentme | and its run in the linux environment right? | 00:01 |
| scientes | delinquentme, yeah it has a RW sd card | 00:02 |
| scientes | delinquentme, but binaries have to be compiled for ARM, x86 binaries wont run | 00:02 |
| delinquentme | and this can be written in any language that can compile to ARM? | 00:03 |
| scientes | correct | 00:03 |
| scientes | or any interpreted language, that has interpreter support on ARM | 00:03 |
| delinquentme | and how about the operation ... that code simply polls over and over ? | 00:04 |
| scientes | and to be apecific armv7, which is what ubuntu targets | 00:04 |
| scientes | delinquentme, linux is "tickless" | 00:04 |
| delinquentme | its running *inside* the ubuntu operating system right? much like any language I run on my laptop ubuntu system | 00:04 |
| scientes | so it only wakes up to meet the next deadline, if it doesn't get an interrupt | 00:04 |
| scientes | yes it is the same ubuntu you run on your laptop, but recompiled for arm | 00:05 |
| scientes | debian GNU/Linux did most of the porting work/troubleshooting | 00:05 |
| delinquentme | and the code would be automatically read from the SD card? | 00:05 |
| scientes | but armv7 hardfloat transition has been helped by ubuntu | 00:06 |
| scientes | delinquentme, its just ext4 filesystem like you use on your hard drive | 00:06 |
| scientes | so it has files just the same, and with the same layout | 00:06 |
| scientes | delinquentme, you can actually run the beagleboard software on your laptop, using qemu-arm | 00:06 |
| scientes | or qemu-arm-static | 00:06 |
| delinquentme | so If i've got a desktop which connects to the beagleboard via ethernet ... and I want the beagle to issue machine commands to MCs that branch off of it | 00:07 |
| scientes | " machine commands to MCs that branch off of it" | 00:08 |
| scientes | i have no idea what you are saying here | 00:08 |
| delinquentme | the beagle runs whatever compiled arm and would then issue commands via that beagleboard software to those branch MCs | 00:08 |
| scientes | you can run all the same server software on e arm that you can run on x86 | 00:08 |
| scientes | postfix, dovecot, postgresql, etc | 00:08 |
| scientes | now, the beagleboard is not the fastest arm board | 00:09 |
| delinquentme | basically the beagle controlling a number of attached MCs | 00:09 |
| scientes | what is a MC? | 00:09 |
| delinquentme | microcontroller | 00:09 |
| scientes | specifically.....? | 00:09 |
| delinquentme | ( sorry ) but yeah I'm trying to use the beagle to run steppers and the like | 00:09 |
| delinquentme | been looking at this one : http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATA_BRIEF/DM00037955.pdf | 00:10 |
| delinquentme | ~ 13 of those | 00:10 |
| scientes | well that has yet another arm cpu inside of it | 00:10 |
| scientes | however it has too little ram and flash to run linux | 00:11 |
| delinquentme | oh yeah im not trying to run linux on those | 00:11 |
| delinquentme | those are what controls the steppers and the sensors etc | 00:11 |
| delinquentme | which then geed information back to the beagle | 00:11 |
| delinquentme | geed = feed* | 00:11 |
| scientes | is that black on the bottom audio? | 00:12 |
| scientes | and the top usb is just the power (5v)? | 00:12 |
| scientes | "one audio DAC" yeah, audio | 00:12 |
| delinquentme | i think theres also a 5v in | 00:13 |
| scientes | seems to me that you use the "SWD" to communicate to it | 00:14 |
| scientes | "digital accelerometer and digital | 00:15 |
| scientes | microphone, one audio DAC with integrated class | 00:15 |
| scientes | D speaker driver, LEDs and push buttons and an | 00:15 |
| scientes | USB OTG micro-AB connector. | 00:15 |
| scientes | " | 00:15 |
| scientes | so i guess that is what it does | 00:15 |
| delinquentme | how to check if it can run communications over the micro usb | 00:15 |
| scientes | well since it says that all that is needed, it probably can | 00:15 |
| scientes | what do you want to do with it? | 00:15 |
| delinquentme | make a liquid handling robot | 00:16 |
| delinquentme | it has a number of modular cores | 00:16 |
| scientes | that thing seems to be audio-oriented | 00:16 |
| scientes | microphone and mono audio out | 00:16 |
| delinquentme | yeah I'm not really sure how the MC industry works | 00:17 |
| scientes | "digital microsoft" (does that mean it has a ADC ?) | 00:17 |
| delinquentme | like it can send signals and thats all I really need | 00:17 |
| delinquentme | i could probably go much simpler TBH | 00:17 |
| scientes | gcc supports compiling firmware IIRC | 00:17 |
| scientes | its the arm-non-gnueabi target for armv5+ | 00:17 |
| scientes | *none | 00:17 |
| delinquentme | but I dont have the capability to design printed circuit boards ... so i need to buy something thats already assembled | 00:17 |
| scientes | and it only has one usable button | 00:19 |
| delinquentme | so yeah just write come C code .. compile it with GCC stick it on a MC like that and let it poll for commands from the beagle | 00:19 |
| delinquentme | yeah I don't really see myself using anything other than a reset button | 00:19 |
| scientes | well, event-based would sure be nicer | 00:19 |
| scientes | delinquentme, you can do that without any MC | 00:20 |
| scientes | you can do that with a seial port | 00:20 |
| scientes | or even a usb keyboard/mouse | 00:20 |
| delinquentme | well for programming it I can attach it however | 00:21 |
| scientes | but yeah that board is designed for audio uses, it doesn't seem applicable for you | 00:21 |
| delinquentme | how does one go about finding a good board for an application? | 00:23 |
| scientes | all the IC vendors have huge lists | 00:23 |
| delinquentme | ( i'm kind of expecting there to be a tool like new egg where there are drop downs and I select the chips and things I want on it | 00:23 |
| scientes | freescale, marvell, broadcom | 00:23 |
| scientes | newark | 00:23 |
| delinquentme | and these are all programmed effectively the same way? | 00:23 |
| scientes | well im still not sure what youwant/are trying to do | 00:24 |
| scientes | arduino is pretty hot these days | 00:25 |
| delinquentme | true but they're also super costly | 00:25 |
| scientes | so is the beagle board | 00:26 |
| delinquentme | ahh yeah that might help :D .. I've got 2 steppers, 1 linear string pot, 1 linear actuator and 2 physical switches | 00:26 |
| scientes | compared to, like, the rasberri pi | 00:26 |
| scientes | delinquentme, how about this: http://www.st.com/stonline/stappl/productcatalog/app?page=productSelectorPage | 00:28 |
| delinquentme | oooooo | 00:30 |
| scientes | http://www.freescale.com/webapp/sps/site/application.jsp?code=APLSTEMOT | 00:30 |
| delinquentme | DSC ? | 00:34 |
| delinquentme | Digital Signal Controller | 00:34 |
| delinquentme | actually I should totally be able to email customer support @ these places and just be like | 00:36 |
| delinquentme | "this is what I need" | 00:36 |
| delinquentme | does u have? | 00:36 |
| delinquentme | also! | 00:36 |
| delinquentme | these are all chips .. is there a name used for the units when they're already attached to a board? | 00:36 |
| scientes | yeah ive come across that prob too | 00:38 |
| scientes | i dont really have an answer for you | 00:38 |
| delinquentme | haha im glad im not nuts :D | 00:40 |
| delinquentme | scientes, what do you do with all this coolness | 00:40 |
| delinquentme | specifically ubuntu arm chips? | 00:40 |
| scientes | well i actually dont have a armv7 comp yet | 00:41 |
| scientes | i only have the sheevaplug | 00:41 |
| scientes | which is armv5, running debian | 00:41 |
| scientes | but i really want a armv7, or better yet armv8 + quad core | 00:42 |
| * scientes wants to experiment with big.LITTLE too | 00:42 | |
| delinquentme | OOo the sheevaplug | 00:42 |
| delinquentme | thats like mischief no? | 00:42 |
| scientes | its kinda old now | 00:42 |
| delinquentme | is this like PHD research scientes ? | 00:43 |
| delinquentme | you can basically hook that sheevaplug up to something and just let it sniff away at wireless packets | 00:44 |
| scientes | the one i have doesn't have wifi | 00:46 |
| scientes | but considering its size and power consumption that sort of use would certainly be feasable | 00:47 |
| scientes | and a good fit for the device | 00:47 |
| scientes | it also has gigabit ethernet, so you could access it remotely at high speed | 00:47 |

| janimo` | ogra_, hi, which packages needed to be touched to get unity-3d gles working? nux, compiz+unity? | 09:23 |
| janimo` | I'd like to to do a GLES rebuild for x86 and touch the minimum numer of packages locally | 09:24 |
| ogra_ | nux, unity, compiz and compiz-plugins-main | 09:27 |
| ogra_ | just grab the packages in precise, they are ready | 09:27 |
| ogra_ | you will need to change the arch checks etc | 09:27 |
| janimo` | ogra_, and all of them need an extra config option passed, none do runtime detection right? | 09:28 |
| ogra_ | right | 09:28 |
| janimo` | ogra_, thanks! | 09:28 |
| ogra_ | talk to alf_ for a different patch set | 09:28 |
| janimo` | ogra_, for now the ones in precise are fine if they actually work with gles | 09:29 |
| ogra_ | iirc the new one they have in linaro can run with GL and GLES enabled | 09:29 |
| ogra_ | not sure when you have to select or if its automatic at all though | 09:29 |
| janimo` | ogra_, ah they already hae packages for that, I'll ask him then | 09:29 |

| LetoThe2nd | infinity: ping | 11:43 |
| infinity | LetoThe2nd: pong? | 11:45 |
| LetoThe2nd | infinity: ogra told me ask you: | 11:45 |
| LetoThe2nd | any ideas why http://paste.pocoo.org/show/582316/ goes bi***ing about some dependency issues concerning linux-libc-dev:i386 and linux-libc-dev in a clean 12.04 chroot, and if you just re-run it, everything is fine? dependency solver problem? | 11:45 |
| infinity | LetoThe2nd: Temporary annoyance with a transition. If you add precise-proposed to your sources.list, it'll be happy. | 11:46 |
| infinity | LetoThe2nd: Should be resolved in ~5 hours when gcc-4.6 is built everywhere, and I can promote gcc and eglibc to release. | 11:46 |
| LetoThe2nd | infinity: ahkay. nothing urgent, so will probably be sorted out soon? | 11:46 |
| LetoThe2nd | i see, thx then. | 11:46 |
| ogra_ | infinity, compiz-plugins-extra (universe) is FTBFS on all arms with the new GLES compiz, should we leave it that way, or upload a package that has the arm arches dropped for final release ? (i dont think anyone ever cared in a port to GLES for these plugins) | 11:46 |
| infinity | ogra_: Ugh, really? Is it not a simple fix? | 11:47 |
| infinity | rsalveti: Hey, wake up and come be helpful. | 11:47 |
| ogra_ | i dont think linaro ever touched that package (not needed for unity) and afaik all GL->GLES switches need heavy patching | 11:48 |
| infinity | ogra_: Dropping the arches isn't necessary, but fixing it would be nice. | 11:48 |
| ogra_ | (more than just a config option) | 11:48 |
| infinity | Needs heavy patching for plugins? That seems wrong. | 11:48 |
| ogra_ | well, even in our normal compiz build on arm we have to disable more than half of the plugins | 11:49 |
| ogra_ | because the functions arent patched yet, i doubt its fixable in time for release and i also doubt linaro will ever care for these plugins | 11:49 |
| infinity | Letting it be FTBFS is fine. As you note, it's universe. | 11:49 |
| infinity | We just need to remove the stale binaries. | 11:50 |
| ogra_ | right, and makes SRUing a possible fix easier | 11:50 |
| infinity | And wow, compiz-plugins-main-gles2.patch is extensive. | 11:50 |
| ogra_ | i still try to catch alf_ or rsalveti to find out if they ever plan to fix that | 11:50 |
| ogra_ | right | 11:50 |
| infinity | What an awful architecture compiz is... | 11:50 |
| ogra_ | well, compared to the compiz patch its still small :) | 11:50 |
| infinity | The GNOME people really got this right with cogl. | 11:51 |
| ogra_ | well, we should just switch to Qt | 11:51 |
| ogra_ | unity-2d ftw | 11:51 |
| ogra_ | but i promised kaleo to not rave about that for a year :) | 11:51 |
| infinity | Heh. | 11:51 |
| infinity | I prefer 2d anyway. | 11:52 |
| infinity | To each their own, though. | 11:52 |
| ogra_ | yeah, and it shouldnt be to hard to get all the functions in that 3D has | 11:52 |
| * ogra_ completely reinstalled his ac100 this weekend from ubuntu-core | 11:52 | |
| ogra_ | using lxde now | 11:53 |
| ogra_ | so much more free ram ! | 11:53 |
| ogra_ | (needed a reinstall to switch to hf) | 11:53 |
| ogra_ | using -core as a base it a big pain in the butt though ... | 11:54 |
| infinity | Well, yes. | 11:54 |
| infinity | It has no installer. :P | 11:54 |
| ogra_ | yeah | 11:55 |
| ogra_ | well, and getting the bootloader setup working by hand isnt really fun | 11:55 |
| LetoThe2nd | <3 debootstrap | 11:55 |
| infinity | I'd suggest feeding core to linaro-image-tools (which works really well), but I assume they have no ac100 target. | 11:55 |
| ogra_ | LetoThe2nd, -core is essentially debootstrap --minbase | 11:55 |
| ogra_ | iirc | 11:55 |
| ogra_ | yeah, ac100 is spethial | 11:55 |
| LetoThe2nd | ogra_: ah yea. | 11:56 |
| infinity | I don't mind my ac100 with unity-2d, but the RAM starvation does hurt. | 11:56 |
| ogra_ | the prob with the ac100 is to get it to a point where you can use the wlan for further install ... thats a real PITA starting from core | 11:56 |
| infinity | I had some builds failing on it because of that. | 11:56 |
| ogra_ | right, with lxde my system now uses 75MB with the idling desktop | 11:56 |
| infinity | ogra_: Hahaha. Yeah, my first ac100 install was from core, and involved a whole lot of wgetting and dpkg -i, and head-scratching. | 11:57 |
| ogra_ | thats half of what unity-2d uses | 11:57 |
| infinity | I don't really know what posessed Toshiba to only put 512MB on the thing. | 11:57 |
| ogra_ | adnroid | 11:57 |
| infinity | If they wanted to be competitive with crappy Atom netbooks, they all have 1G. | 11:57 |
| fhilly | Hi All | 11:58 |
| ogra_ | i dont think that was the plan with the ac100 | 11:58 |
| infinity | Yeah, I suppose it was Android-specific. | 11:58 |
| infinity | But even Android breathes more easily with 1G. | 11:58 |
| ogra_ | its more like a POC of using android on netbooks | 11:58 |
| ogra_ | well, it is using 2.1 in the original setup ... that doesnt need much ram ... and has not many apps :) | 11:58 |
| infinity | It's the one thing I'd change about my phone, if I could (and the only reason I might look for upgrades) | 11:59 |
| fhilly | anyone have detailed documentation on the architecture and packages on Ubuntu core rootfs? | 11:59 |
| LetoThe2nd | hrhrhrhr | 11:59 |
| ogra_ | theer should be a manifest file in the download dir | 11:59 |
| infinity | Is there? | 11:59 |
| ogra_ | that has the packagelist | 11:59 |
| ogra_ | infinity, if there isnt ... it *should* :) | 11:59 |
| infinity | Oh look, I do publish the manifest. | 11:59 |
| infinity | Go me. | 12:00 |
| ogra_ | (there is) | 12:00 |
| ogra_ | fhilly, http://cdimage.ubuntu.com/ubuntu-core/daily/current/ ... | 12:00 |
| ogra_ | and http://cdimage.ubuntu.com/ubuntu-core/releases/ for released images | 12:01 |
| fhilly | thanks ogra, I assume there is detailed information in there? | 12:01 |
| ogra_ | fhilly, well, there are the manifests and you can see which arches it is built for | 12:01 |
| fhilly | how about rootstock? is it still maintained? | 12:02 |
| ogra_ | no | 12:02 |
| fhilly | thanks ogra | 12:02 |
| ogra_ | hmm, that remonds me i should probably file a removal bug for the package | 12:02 |
| fhilly | ok, if I want to get involved in the building process of the Ubuntu core rootfs, is there any specific root advised? | 12:02 |
| ogra_ | we use live-build (config files for that are in livecd-rootfs) to roll it | 12:03 |
| ogra_ | just take a look at the source of these | 12:03 |
| infinity | ogra_: I'll happily remove rootstock right now, no need for a bug. | 12:03 |
| ogra_ | infinity, go for it ! | 12:03 |
| infinity | ogra_: But I think you should do something about the LP project too. | 12:03 |
| ogra_ | yeah, i'll kill it | 12:04 |
| fhilly | ok thanks a lot | 12:04 |
| ogra_ | or at least mark it inactive or so | 12:04 |
| ogra_ | there are some good code snippets in rootstock i wouldnt like to lose | 12:04 |
| ogra_ | (the fifo to serial interaction with qemu for example to do stuff scripted inside a VM) | 12:05 |
| fhilly | well, I have tried ubuntu-core rootfs on x86, however I believe there is "sudo" package missing, as the user will not be able to install anything including "sudo" unless unlock the files system as sudo or su user | 12:05 |
| ogra_ | fhilly, thats on purpose | 12:05 |
| ogra_ | ubuntu-core is to *build* images on top (or as an easy to use base for a chroot), not actually to use it as an install base ... | 12:06 |
| infinity | sudo would be kinda useless given that there's also no user. | 12:07 |
| infinity | rootstock | 0.1.99.4-0ubuntu1 | precise/universe | source, amd64, armel, armhf, i386, powerpc | 12:07 |
| infinity | rootstock-gtk | 0.1.99.4-0ubuntu1 | precise/universe | all | 12:07 |
| LetoThe2nd | infinity: one could make an alias called "medo" that root himself can use. | 12:07 |
| infinity | ogra_: ^--- That rootstock? | 12:07 |
| ogra_ | the typical usecase is for something like embedded IVI systems (car entertainment) where you wont even have a user account thats accessible by the ednuser | 12:07 |
| ogra_ | \o/ | 12:07 |
| ogra_ | infinity, yeah | 12:07 |
| ogra_ | funny, i didnt know we built it for armel/armhf ... | 12:08 |
| fhilly | forgive my ignorance but can you tell me why? as in the short explanation of it, it says after you finish you can use pat-get, how can we use apt-get if we don't have sudo? I am new to community stuff and I am trying to get involve so I know I am asking too much | 12:08 |
| fhilly | ok I see | 12:08 |
| LetoThe2nd | ogra_: haven't you noticed all the people in #pandaboard who asked about starting from -core because the sound of the name suggested a more minimal image to them? | 12:08 |
| infinity | And it is a minimal image. | 12:09 |
| infinity | It just also has no installer. | 12:09 |
| fhilly | lets say I want to build Ubuntu distro for ARM (beagle board) can I do it based on Ubuntu -core rootfs, or there is a better way of doing things? | 12:09 |
| ogra_ | well, it is | 12:09 |
| ogra_ | but you need to do a ton of things manually depending on your usecase | 12:09 |
| infinity | ogra_: Removed, should be gone in the next publisher run. | 12:09 |
| ogra_ | fhilly, well, i would just use one of the official beagle images from ubuntu for that | 12:10 |
| * ogra_ hugs infinity | 12:10 | |
| fhilly | is there any detailed documentation about it? guys I see you know everything about it, instead of me asking you, I could just read and get back to you if I have any questions | 12:10 |
| ogra_ | if you want a minimal install on your beagle, use the server image | 12:10 |
| ogra_ | see https://wiki.ubuntu.com/ARM/OMAP for instructions etc | 12:11 |
| ogra_ | if you want even more flexibility, use the netinstall SD card image | 12:12 |
| fhilly | orga_ I am trying to get as much information as I can, as I would liek to be part of the community at one point, and contribute. it is not about the BeagleBoard only | 12:12 |
| ogra_ | (falsely called netboot on that wikipage) ... but nore that you nedd a network connection wired up for thet indeed | 12:12 |
| ogra_ | well, just hang out in this channel ... thats already a good step to being involved in the community ;) | 12:13 |
| LetoThe2nd | fhilly: and, hint: tabcompletion for nicks works in any sane IRC client :) | 12:13 |
| fhilly | ok thanks LetoThe2nd | 12:14 |
| fhilly | it works | 12:14 |
| fhilly | as a starting point for me, where can I start contributing? in terms of anything I could do? | 12:15 |
| LetoThe2nd | oO( purge errors out of omappedia/elinux *duckandrun* ) | 12:15 |
| ogra_ | http://qa.ubuntuwire.org/ftbfs/ ... you could for example have a look at all packages that only fail on armel/armhf | 12:15 |
| ogra_ | or weed through launchpad and look for bugs that the ubuntu-arm team is subscribed to | 12:16 |
| fhilly | then try to fix it, and report back? | 12:16 |
| ogra_ | if you have HW you can help testing images right before milestone (or final) releases | 12:16 |
| ogra_ | right | 12:16 |
| fhilly | ok | 12:16 |
| fhilly | I have BeagleBoard XM rev: C4 and BeagleBone | 12:17 |
| fhilly | any testing procedures? | 12:17 |
| janimo` | infinity, !! I started using a caching proxy and it's great! apt-cacher-ng | 12:18 |
| janimo` | which year are you welcoming me into? | 12:18 |
| * ogra_ uses approx | 12:19 | |
| janimo` | I just picked this one as at one point in one of the mailing lists it was mentioned it more or less works out of the box | 12:20 |
| janimo` | and it indeed does, besides putting a line in apt.conf | 12:21 |
| ogra_ | approx as well and i find it easier to configure for special cases like ports.u.c | 12:21 |
| * infinity just has a local Ubuntu and Debian mirror. | 12:21 | |
| infinity | ... running on an i.MX53 | 12:22 |
| ogra_ | http://www.grawert.net:9999/ubuntu-ports ... :) | 12:22 |
| ogra_ | thats my laptop | 12:22 |
| janimo` | ... uphill | 12:22 |
| ogra_ | (as long as i dont take it with me indeed (which i really rarely do since i have the ac100)) | 12:22 |
| fhilly | how can I test the images before release? where can I get them from? can I subscribe to get notifications? | 12:27 |
| LetoThe2nd | fhilly_: they're all up on the servers | 12:34 |
| LetoThe2nd | fhilly_: http://cdimage.ubuntu.com/daily-preinstalled/current/ for example | 12:35 |
| morphis | LetoThe2nd: you know with which tool the images are build? live-build? | 12:36 |
| LetoThe2nd | morphis: no idea. | 12:37 |
| morphis | infinity: you know how they are build? | 12:37 |
| infinity | Which images? | 12:38 |
| infinity | But yes, we use live-build to create live/preinstalled filesystems. | 12:38 |
| morphis | infinity: the images you can download from here: http://cdimage.ubuntu.com/daily-preinstalled/current/ | 12:39 |
| ogra_ | fhilly_, for testing you can subscribe to teh images you want to be notified about on http://iso.qa.ubuntu.com/ | 12:39 |
| infinity | morphis: live-build to create the filesystem, and then some hackery on top of that to make it bootable. | 12:40 |
| morphis | infinity: means installing system dependent files (fstab,kernel-modules, ...) | 12:40 |
| ogra_ | kernel modules come from the kernel package ... fstab and HW sepcific bits usually come from the installer | 12:41 |
| infinity | And creating a FAT filesystem, and populating it with a bootloader and kernel, and... | 12:41 |
| fhilly_ | ogra_, LetoThe2nd thanks | 12:41 |
| morphis | infinity: ok | 12:41 |
| fhilly_ | what do I have to do? just install them? do something specific? run scripts? or just work as normal? | 12:46 |

| djszapi | Hey! Is it okay if the daemon part of my project is started automatically by an upstart job put into the /etc/init/ folder with the ubuntu desktop version ? Is there a better interface for that like we had /etc/init/apps on Harmattan ? | 15:32 |
| pnphi | i don't know to fix this problem | 15:57 |
| pnphi | checking for pam_start in -lpam... no configure: error: "PAM libraries not found" make: *** [debian/stamp-autotools] Error 1 dpkg-buildpackage: error: debian/rules build gave error exit status 2 | 15:57 |
| ogra_ | pnphi, just add the right dependency to your packge (or if you dont build a package, make sure to have the right -dev package installed that gives you the pam headers | 15:58 |
| ogra_ | ) | 15:58 |
| pnphi | detail ? | 15:59 |
| ogra_ | djszapi, i dont know /etc/init/apps, but upstrart is surely a proper way to start daemon processes | 15:59 |
| ogra_ | pnphi, well, its your project, you should know what deps you need to build whatever you build there | 16:00 |
| djszapi | ogra_: start on runlevel [23] or [12345] ? | 16:00 |
| pnphi | so...i install deps of package | 16:00 |
| pnphi | !!! | 16:00 |
| ogra_ | well, usually runlevels are moot anyway :) all debian and ubuntu systems default to 2 | 16:00 |
| pnphi | what runlevel ? | 16:01 |
| ogra_ | (so [2 3<9 should be good) | 16:01 |
| ogra_ | err | 16:01 |
| ogra_ | [2 3] | 16:01 |
| pnphi | dpkg-buildpackage: error: debian/rules build gave error exit status 2 | 16:02 |
| pnphi | what the err ? | 16:03 |
| ogra_ | read your build log it should say | 16:03 |
| djszapi | ogra_: runlevel 5 means for instance "Start the system normally with appropriate display manager. ( with GUI )" | 16:04 |
| ogra_ | djszapi, it doesnt | 16:04 |
| djszapi | ogra_: http://en.wikipedia.org/wiki/Runlevel#Typical_Linux_runlevels | 16:05 |
| ogra_ | (nmot sure where you got that line from, but on debian based systems runlevel 2-5 are identical) | 16:05 |
| ogra_ | 1 is singleuser, 6 is reboot | 16:05 |
| ogra_ | (and 0 is halt) | 16:07 |
| djszapi | read the link. | 16:07 |
| pnphi | configure.ac:3: warning: AC_INIT: not a literal: http://bugzilla.gnome.org/enter_bug.cgi?product=gdm if [ -e ./Makefile.am ]; then cd . && automake-1.11 ; fi configure.ac:3: warning: AC_INIT: not a literal: http://bugzilla.gnome.org/enter_bug.cgi?product=gdm data/greeter-autostart/Makefile.am:10: `%'-style pattern rules are a GNU make extension automake-1.11: cannot open < gnome-doc-utils.make: No such file or directory make: *** | 16:07 |
| pnphi | oh my god | 16:07 |
| djszapi | and I have the desktop version of ubuntu on my pandaboard. | 16:07 |
| ogra_ | how would reading thge link change anything ? | 16:07 |
| djszapi | the linux runlevels are defined in there... | 16:07 |
| ogra_ | no, they arent ... someone wrote up how the runlevels on his fedora box look like i guess | 16:08 |
| ogra_ | first of all, runlevels are moot, upstart is event based and only retains the runlevel concept for backwards compatibility ... if you develop something from scratch i would rather tie to an even than to a runlevel .... | 16:09 |
| ogra_ | and second, i onlycan repeat (for the last time now) runlevels 2-5 are identical on debian based systems) | 16:10 |
| djszapi | what would you recommend to me, if my goal is to run my binary during the bootup ? | 16:10 |
| ogra_ | rsalveti, poke ... seems compiz-plugins-extra FTBFS with the new compiz | 16:11 |
| djszapi | that is the trigger event. | 16:11 |
| rsalveti | ogra_: oh well, let me check | 16:11 |
| ogra_ | rsalveti, well, i didnt expect anyone to have a patch or so, just wanted to make sure i'm right | 16:11 |
| ogra_ | its a universe package etc etc blah blah ... | 16:11 |
| rsalveti | plugins-main is the one needed, this extra might not be useful in the end | 16:12 |
| ogra_ | djszapi, well, what does your daemon do ? i.e. for a network based service i would tie to a network-up event for something related to HW i would tie to a udev event | 16:12 |
| djszapi | start on runlevel [23] stop on runlevel [!23] | 16:12 |
| djszapi | I had the impression I should do something like that for this goal. | 16:12 |
| rsalveti | janimo`: there's a runtime detection for unity for gles as well | 16:13 |
| ogra_ | rsalveti, yes, thats what i thought, just wanted to look if you guys possibly have a patch | 16:13 |
| djszapi | ogra_: listening to the serial port, and act accordingly for the incoming data. | 16:13 |
| djszapi | so prolly udev. | 16:13 |
| rsalveti | janimo`: /usr/lib/nux/unity_support_test -p | 16:13 |
| rsalveti | ogra_: I'll check | 16:13 |
| ogra_ | djszapi, well, either use the runlevel or take a look if there is a udev event when the serial device shows up | 16:13 |
| pnphi | dpkg-buildpackage: error: debian/rules build gave error exit status 2 | 16:25 |
| pnphi | @ @ | 16:25 |
| ogra_ | read the log, find the error, fix it :) | 16:26 |
| janimo` | rsalveti, yes, ran that already and works fine, still unity still crashes on logon | 16:38 |
| djszapi | ogra_: I am unsure if there is an udev event for that. | 16:39 |
| smplman | are there any updates on SGX for omap3? | 16:58 |
| ben_ | Out of interest. | 17:10 |
| ben_ | Does the l-cache actually destroy back to back compatibility with prior programs? | 17:10 |
| ben_ | Because it forces ARM into a modified Harvard Architecture... | 17:10 |
| ben_ | Take for example the case where you write over and instruction, but the l-cache keeps a prior version and then executes the prior version. | 17:11 |
| ogra_ | djszapi, so just take [23] | 17:11 |
| ben_ | You have to force the cache to clear... | 17:11 |
| djszapi | ogra_: might fail if udev is not up yet | 17:11 |
| djszapi | since connecting to the serial port depends on the udev | 17:12 |
| ogra_ | udev comes up in initrd | 17:12 |
| djszapi | so it is guaranteed my binary would be run later ? | 17:12 |
| ogra_ | and i think also before the runlevels start | 17:12 |
| ogra_ | ogra@horus:~$ grep "start on" /etc/init/udev.conf | 17:13 |
| ogra_ | start on virtual-filesystems | 17:13 |
| djszapi | so ? | 17:13 |
| ogra_ | yup ... udev comes up with /proc, /sys and friends | 17:13 |
| ogra_ | way before anything cares for runlevels | 17:13 |
| djszapi | fine :-) | 17:16 |
| djszapi | does the kernel care about the proper respawning ? Say, I open the serial port while launching the daemon, and I would ideally close the serial port while stopping. | 17:16 |
| djszapi | what if the daemon dies, and there is a respawning ? | 17:16 |
| djszapi | there is a proper serial port close and then open again ? | 17:17 |
| ogra_ | no, not the kernel ... init does (well upstart in our case) | 17:19 |
| djszapi | ogra_: is "stop on runlevel [!23]" fine for stopping ? | 18:01 |
| recur | is there an arm equivalent to dmidecode ? | 19:27 |
| infinity | recur: That would imply there was such a thing as device tables on ARM. | 19:31 |
| recur | Hi infinity | 19:31 |
| recur | ah, so I'm completely out of luck then :) | 19:31 |
| infinity | Pretty much. | 19:31 |
| recur | I wanted to programmatically get my hardware serial, but I've used dmidecode for that in the past. | 19:31 |
| recur | thanks for the info! | 19:31 |
