|---|---|---|
| rbasak | pbuckley: you'll need gcc-arm-linux-gnueabihf installed | 00:42 |
| rbasak | err, gcc-arm-linux-gnueabi | 00:42 |
| rbasak | for armhf, s/armel/armhf/ and it's gnueabihf | 00:43 |
| pbuckley | thank you | 00:44 |
| pbuckley | im stil waiting for my first compile i kicked off about 4 hours ago | 00:45 |
| pbuckley | so cross compiling is really the only way | 00:45 |
| pbuckley | i can do this in any sort of real time frame | 00:45 |
| pbuckley | i wonder if distcc is still around | 01:29 |
| pbuckley | sweet it is.. anyone have success with it on arm? | 01:31 |
| Neko | it works | 01:31 |
| pbuckley | ty | 01:32 |
| Neko | it's not very useful though, if you have 40 arm boxes to hook up with it you're probably also in posession of a rather powerful PC too :) | 01:32 |
| pbuckley | well | 01:32 |
| pbuckley | true.. but even in ec2 the kernel is taking forever.. ive gotten spoiled with near instant builds | 01:32 |
| pbuckley | going to spin up a couple more instances | 01:32 |
| pbuckley | and distcc this shiznit | 01:33 |
| twb | Neko: some stuff can't be cross-compiled, though | 01:33 |
| twb | Although the same stuff probably also has trouble with distcc... | 01:34 |
| Neko | and that;s where you break out qemu to emulate arm enough to get the bits that can't be cross-compiled done | 01:34 |
| twb | I guess. | 01:34 |
| twb | Not all arches get so much love in qemu :-) | 01:34 |
| Neko | suse manage it in their build service just fine, ubuntu are getting this stuff up and running. compiling natively on arm boxes is just looking for a long wait no matter how many you have. | 01:34 |
| Neko | when you hit quad or eight core 1.8GHz monsters with 4GB RAM and real hard disks, yeah, it'll make sense again, but they don't exist yet. Not quite yet :) | 01:35 |
| twb | AFAIK Debian still relies heavily on native builds | 01:35 |
| Neko | and it'd still be faster on a PC. Nobody does a "native" Android build | 01:36 |
| * pbuckley drools about the thought of an eightcore 4gb ram monster | 01:36 | |
| Neko | yeah we own the armhf build farm.. | 01:36 |
| twb | Well, android are crack-smoking java monkeys, what do you expect | 01:36 |
| Neko | and it works.... but there's a better way | 01:36 |
| pbuckley | whats the better way? | 01:36 |
| Neko | cross-compile :] | 01:36 |
| pbuckley | heh | 01:37 |
| Neko | use your 8-core hyperthreaded xeon with 32gb ram and a 4TB raid array and build all of android in 25 minutes. | 01:37 |
| twb | I expect it'll become trendier in Debian once multilib stuff is done | 01:37 |
| twb | Neko: that still takes 25 minutes? You can build openwrt on an *atom* in that time | 01:38 |
| Neko | openwrt is a little smaller though | 01:38 |
| Neko | building a 6MB ROM for a router is a bit different to something that comes out about 300MB worth of apps and java crap | 01:39 |
| Neko | spitting a kernel out takes a couple minutes for a full distclean build.. you'd never do that on ARM even if you had 50 boxes doing it | 01:39 |
| pbuckley | im at about 5 hours for building 3.2.0 on my pandaboard | 01:40 |
| Neko | it takes 80 minutes on an Efika MX :) | 01:40 |
| twb | Those extra 294MB are just bloat ;-) | 01:40 |
| pbuckley | twb: thats the java ;) | 01:41 |
| Neko | have 50 of them and it might take half an hour, maybe 10 minutes if you're lucky | 01:41 |
| Neko | twb, I did say java crap :D | 01:41 |
| pbuckley | efika mx you say | 01:41 |
| * pbuckley googles | 01:41 | |
| twb | Now now, just because dalvik walks like a duck and quacks like a duck, doesn't mean Oracle can sue Google ;-) | 01:41 |
| infinity | pbuckley: The Efika's much slower than your Panda, I wouldn't bother with the googling. | 01:42 |
| GrueMaster | pbuckley: If it has taken 5 hours on your panda, you're doing something wrong. https://launchpad.net/ubuntu/+source/linux-ti-omap4/3.2.0-1405.7/+build/3121438 | 01:42 |
| GrueMaster | And that system isn't even optimized. I think it is running natty. | 01:42 |
| pbuckley | GrueMaster: apt-get --only-source source linux-ti-omap4 (something); cd /usr/src/linux; make oldconfig; make | 01:43 |
| pbuckley | is basically all i did | 01:43 |
| GrueMaster | Are you running on SD or USB Sata? | 01:43 |
| pbuckley | SD | 01:43 |
| twb | GrueMaster: he is probably building with debug on | 01:44 |
| GrueMaster | Ah. That explains it. You'll see almost 10x performance increase on USB. | 01:44 |
| twb | That ALWAYS gets me | 01:44 |
| Neko | I'm regretting buying a pandaboard, not because it's slow (usb disk makes it fun to use again) but because everything just seems not to be as good as you'd think | 01:45 |
| Neko | awesome CPU, awful TI peripherals | 01:45 |
| Neko | except the wireless, that works really well | 01:45 |
| GrueMaster | Looking at the buildlog from the link I posted, the buildd is running Natty (Kernel version: 2.6.38-1209-omap4 #20-Ubuntu). | 01:45 |
| GrueMaster | The panda is essentially a cellphone dev platform. When thought of along those terms, it is actually quite good. | 01:46 |
| Neko | it's a shame nobody's making a real omap4 desktoppy kind of system that's been optimized for usage and not just developing phones | 01:46 |
| Neko | the other TI dev board is much better than the panda for that though too | 01:46 |
| Neko | like.. if you had the choice you'd buy the MX53 EVK and not bother with the Quickstart | 01:47 |
| Neko | if you were developing phones that is | 01:47 |
| GrueMaster | Actually, there are a lot of non-phone systems out there (kindle fire, nook tablet). And I heard of one system coming soon that will just plug into a spare hdmi port on your tv. | 01:47 |
| twb | I thought omap4 was a better platform than the dragonball | 01:47 |
| steev_ | not a big enough market for it | 01:47 |
| Neko | tablets are just big phones at the end of the day, same development model | 01:47 |
| Neko | omap4 needs a trimslice, efika mx kind of thing | 01:48 |
| GrueMaster | True. Can't wait for omap5. Could be interesting. | 01:48 |
| Neko | well I'm duty bound to wait for MX6, but I can't help thinking most companies will run to nVidia before TI at the moment | 01:48 |
| Neko | all the new tablets in the pipeline seem to be tegra3, if that is at all realistic | 01:48 |
| Neko | I remember when they were all going to be MX51, hahahaha.. | 01:49 |
| Neko | what happens at CES, stays at CES | 01:49 |
| GrueMaster | Yea, well.... | 01:49 |
| pbuckley | a tegra3 pandaboard like board would be fun | 01:50 |
| twb | *I* remember in like 2008 when asus demoed an 9" eeepc running arm | 01:50 |
| twb | And then I had to wait four years for the tf101 | 01:50 |
| pbuckley | so whats the trick to turn debug mode off? | 01:50 |
| twb | pbuckley: make menuconfig, find it in the kernel hacking section | 01:51 |
| twb | It basically means whether it builds with -g | 01:51 |
| GrueMaster | twb: That is on by default in all of our kernels, from what I can tell. | 01:53 |
| twb | GrueMaster: it is on standard ubuntu and debian kernels, yes | 01:53 |
| twb | but it makes compile take an order of magnitude longer, ESPECIALLY if you have slow I/O | 01:54 |
| pbuckley | ah k | 01:54 |
| pbuckley | thanks | 01:54 |
| twb | CONFIG_DEBUG_KERNEL=y I guess, I don't have menuconfig in front of me right now | 01:54 |
| twb | But IME you can't just edit .config you need to use the UI | 01:54 |
| pbuckley | E: Package 'ncurses' has no installation candidate | 01:55 |
| pbuckley | oh wait | 01:55 |
| pbuckley | that changed to | 01:55 |
| GrueMaster | I think you can if you run make oldconfig afterwards. | 01:55 |
| pbuckley | ncurses-base | 01:55 |
| pbuckley | wow that package name changed again | 01:55 |
| twb | libncurses5-dev or so | 01:56 |
| pbuckley | though im a bit surprised it doesnt get installed with apt-get build-dep | 01:56 |
| twb | ncurses-base is just terminfo files | 01:56 |
| twb | build-dep of a kernel *source* package? | 01:56 |
| pbuckley | well know.. but of the linux-kernel package | 01:57 |
| pbuckley | s/know/no | 01:57 |
| twb | linux-kernel is a metapackage, no build deps | 01:57 |
| pbuckley | ah | 01:57 |
| infinity | libncurses5-dev isn't a build-dep of the kernel because the kernel build doesn't call menuconfig. | 01:58 |
| pbuckley | fair enough | 01:58 |
| twb | infinity: right, thanks | 02:00 |
| pbuckley | flag changed.. thank you for the tip | 02:00 |
| pbuckley | :) | 02:00 |
| pbuckley | and on that note its time to go home | 02:01 |
| twb | If building natively, you can also do "make localmodconfig" and "make localyesconfig" to compile all used modules in, and disable all unused modules | 02:12 |

| krosswindz | GrueMaster: around? | 17:14 |
| GrueMaster | Very much so, sadly. Need to lose weight. | 17:15 |
| GrueMaster | Oh, you meant something else? | 17:15 |
| krosswindz | GrueMaster: I got a second usb serial cable | 17:15 |
| krosswindz | GrueMaster: I have the same issue as well, not being able to hook on to the serial port | 17:16 |
| krosswindz | GrueMaster: stty hangs | 17:16 |
| GrueMaster | Very odd. | 17:16 |
| GrueMaster | I have not seen that issue and I have 7-8 usb-serial cables (I lost track). | 17:17 |
| GrueMaster | Do you have any other serial devices you can test that cable with? | 17:17 |
| krosswindz | GrueMaster: baud_rate = baud_base / divisor? | 17:17 |
| GrueMaster | Not that I know of. | 17:17 |
| krosswindz | I just pulled an ancient desktop I have | 17:17 |
| krosswindz | I am seeing if it will boot of a USB flash drive | 17:18 |
| GrueMaster | You will need a crossover to connect to a regular desktop. | 17:18 |
| GrueMaster | (or are you trying it as a host?) | 17:18 |
| krosswindz | trying it as a host | 17:18 |
| krosswindz | let it export serial console | 17:19 |
| krosswindz | see if I can connect to it | 17:19 |
| krosswindz | I am wondering if setserial for some reason isnt detecting pl2303 | 17:19 |
| krosswindz | I tried my second laptop booting lucid | 17:20 |
| krosswindz | I have the same issue with it as well | 17:20 |
| GrueMaster | I don't see why it would have issues. Works fine here on all my systems from Lucid forward. | 17:20 |
| GrueMaster | That is disturbing. | 17:20 |
| krosswindz | Bus 005 Device 008: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port | 17:21 |
| krosswindz | from lsusb | 17:21 |
| GrueMaster | Most of the usb serial cables I have are from Trendnet. I also have 1 4-port usb-serial cable. All of them use the pl2303 chip. | 17:21 |
| krosswindz | the keyspan which I borrowed works right out of the box | 17:22 |

| === Jack87|Away is now known as Jack87 | ||
| === Jack87 is now known as Jack87|Away | ||
| GrueMaster | dioxin: Nope, just back from lunch. | 21:43 |
| dioxin | GrueMaster: would you be able to guide me in the ways of local repositories? I've got ubuntu 10.04 on the spare box, just doing first round of updates now | 21:44 |
| GrueMaster | dioxin: Here is my ubumirror.conf: http://paste.ubuntu.com/833211/ | 21:46 |
| GrueMaster | With that, you just add a crontab job for the specific ubumirror app you want to run (ubuports for ports.ubuntu.com). | 21:47 |
| dioxin | can I just sudo apt-get install ubuports ? | 21:50 |
| GrueMaster | dioxin: sudo apt-get install ubumirror. ubuports is one script in the package. The package isn't very big. | 21:51 |
| GrueMaster | My cron job is: | 21:52 |
| GrueMaster | cat /etc/cron.d/ubumirror | 21:52 |
| GrueMaster | # Update archive mirror every two hours. | 21:52 |
| GrueMaster | 0 */2 * * * root /usr/bin/ubuports >> /var/log/ubumirror/cron.log | 21:52 |
| dioxin | postfix local only? | 21:52 |
| dioxin | (from install of ubumirror) | 21:52 |
| GrueMaster | The /var/log/ubumirror/cron.log file only traps output from the cron job. ubuports (and all of the other ubu scripts) create their own logs in the same directory. | 21:53 |
| GrueMaster | postfix local (unless you want it to run a larger mail server). | 21:53 |
| GrueMaster | ubumirror scripts use that to send failure notices. | 21:54 |
| dioxin | where does the ubumirror.conf go? /usr/bin/ubuports ? | 21:57 |
| GrueMaster | I recommend using my ubumirror.conf and change the destination paths appropriate to your environment. Mine is set to ignore everything except armel/armhf on ports.ubuntu.com. It also pulls the daily arm images from cdimage.ubuntu.com (using ubucdimage script), but I don't recommend it as it can be slow. Better to use zsync and pull as needed. | 21:57 |
| GrueMaster | ubumirror.conf goes in /etc | 21:57 |
| GrueMaster | See dpkg-query -L ubumirror for all the file locations. | 21:58 |
| dioxin | done it in the /etc/ directory | 21:58 |
| dioxin | ... only need to wait 1 minute... | 21:59 |
| dioxin | changed the 2 to a 1 | 21:59 |
| GrueMaster | My conf file does not mirror the source files, but it does get everything needed for netboot install. First run will take several hours (like overnight). | 21:59 |
| dioxin | how can I tell its running? ps -U root ? | 22:00 |
| GrueMaster | I found that every 2 hours is enough. | 22:00 |
| GrueMaster | ps ax|fgrep rsync | 22:00 |
| GrueMaster | Or tail -f /var/log/ubumirror/ubuports.log | 22:00 |
| pbuckley | GrueMaster: my kernel compile finally finished ;) | 22:02 |
| pbuckley | only took 7 hours | 22:02 |
| GrueMaster | pbuckley: Cool. how long did it take? | 22:03 |
| pbuckley | went alot faster after i shutdown firefox | 22:03 |
| pbuckley | about to boot it.. hopefully those patches help | 22:03 |
| pbuckley | next time ill be sure to turn off that kernel hacking debug stuff | 22:08 |
| dioxin | GrueMaster: I'm getting errors that /server/mirrors/linux-distro blahblah no such file or directory | 22:08 |
| GrueMaster | Yea, those paths are on my mirror. You need to edit /etc/ubumirror.conf and change all /server/mirror paths to something sane on your server. | 22:09 |
| GrueMaster | My server has 4 partitions: /server/data /server/mirror /server/media /server/roots. I doubt your system will be the same. | 22:10 |
| GrueMaster | Once you have the mirror, it will look like <your local path to>/ports.ubuntu.com/ubuntu-ports/* | 22:11 |
| dioxin | I've just added /server/mirror/linux-distros/Ubuntu/ports.ubuntu-com/ubuntu-ports :D | 22:11 |
| GrueMaster | Well, copy exact is one way to go. :P | 22:12 |
| dioxin | I've just built the box specially for this task, it dont really matter :D | 22:13 |
| GrueMaster | On my system, in my www directory (created by the web server), I have a symlink to /server/mirror/linux-distros/Ubuntu/ports.ubuntu-com/ubuntu-ports. That way, the mirror resolves to http://<mirror server>/ubuntu-ports, which makes changing the sources.list easier. | 22:13 |
| dioxin | I guess I have to sort out the symlink for the apache later..... | 22:14 |
| dioxin | ok I think I just added the symlink :D | 22:17 |
| dioxin | GrueMaster: do you guys have a x86 >> armv7 cross compiler up and running yet? | 22:40 |
| suihkulokki | dioxin: on x86 host just apt-get install g++-arm-linux-gnueabi | 22:41 |
| GrueMaster | What he said. :P | 22:41 |
| dioxin | kk I might have to try that once I get my hexa server back up and running :D | 22:42 |
| dioxin | it really needs the other CPU tho :( | 22:43 |
| dioxin | soon my precious! SOOOOON | 22:43 |
| GrueMaster | heh | 22:43 |
| dioxin | is distributed compilation supported out of the box for x86 to arm? | 22:44 |
| dioxin | (me nub, be gentle) | 22:44 |
| GrueMaster | I have no idea. Usually, cross compiling is only recommended for small projects or projects that don't do any post-compile processing (like running unit tests, etc). | 22:49 |
| GrueMaster | And those projects normally fail on a distcc type environment anyways. | 22:49 |
| dioxin | boo :( | 22:50 |
| dioxin | I've got soooo much x86 horse power available :( | 22:51 |
| prpplague | dioxin: unless you are doing a really really really big compile, simply have a dual core box and passing a -j4 to make will be plenty | 22:53 |
| prpplague | dioxin: i can do a complete android build in under 20 minutes on a dual core 2ghz box | 22:53 |
| dioxin | I've a 2.4 Ghz Hex core with hyperthreading ... so I might be able to do that in 3 minutes :) | 22:54 |
| dioxin | I was expecting a full build to take much longer | 22:55 |
| === dduffey is now known as dduffey_afk | ||
| dioxin | GrueMaster: how do I tell the repo is completely downloaded.... the sync stopped running.... | 23:31 |
| dioxin | sudo /usr/bin/ubuports & stopped almost immediately... | 23:32 |
| GrueMaster | On your arm system, edit /etc/sources.list to point to it instead of ports.ubuntu.com and run apt-get update for starters. | 23:32 |
| GrueMaster | Also, check the ubumirror logs (/var/log/ubumirror/ubuports.log.* | 23:33 |
| GrueMaster | ) | 23:33 |
| dioxin | kk its running again, I'll check properly in the morning | 23:36 |
