  • [10:45:38] <lundmar> koen, great thank you for the non help! I'm trying to play nice here. I already did my research on the Linux kernel support for the xM but I can not find confirmation of anyone actually running mainline on the xM board. Apparently this is not the right place to seek this information.
  • [10:46:17] <av500> lundmar: "running" linux is a vague term
  • [10:46:28] <av500> booting into a serial console I am quite sure works
  • [10:46:34] <av500> some people are happy with that
  • [10:46:51] <aholler> as i am ;)
  • [10:47:03] <_cjp> me too
  • [10:47:13] <lundmar> good, that confirms it for me then :)
  • [10:47:23] * dENNES1 is now known as dENNES
  • [10:47:38] <_cjp> of course mainline is a little vague too
  • [10:47:40] * av500 wonders what was confirmed
  • [10:47:53] <av500> _cjp: vague * vague = ?
  • [10:47:56] <lundmar> av500, and you do mean something more recent than eg. 2.6.37 right?
  • [10:47:59] <_cjp> very latest?
  • [10:48:04] <lundmar> cjp, yes
  • [10:48:08] <av500> lundmar: you said mainline
  • [10:48:17] <lundmar> eg. 3.1, 3.2
  • [10:48:30] <lundmar> latest
  • [10:48:41] <av500> nothing is as obsolete as yesterdays mainline linux....
  • [10:49:03] <aholler> exactly, that was 3.1
  • [10:49:04] <_cjp> can't say I've tried the very latest, but I'm certain we had 3.1.x up and running
  • [10:49:51] <lundmar> cjp, ok good to know for me.
  • [10:50:42] <lundmar> because working on old linux kernel is not preferable when doing drivers and pushing them upstream.
  • [10:50:53] <aholler> we are not counting our secret dozens patches on top of mainline ;)
  • [10:51:03] <_cjp> lundmar: most of the "fun" is getting your .config tuned. I'm afraid it's an iterative process to figure out what and does not work. I'd avoid going for the big bang and hoping it all suddenly falls into place.
  • [10:51:22] <_cjp> aholler: you give the community a very bad name ;-)
  • [10:51:22] <lundmar> so you see I can't be stuck on old kernel like 2.6.37 that many of the bloated embedded distributions are pushing.
  • [10:51:37] <av500> yes, they are all evil
  • [10:51:47] <av500> what driver would that be?
  • [10:52:04] * dENNES (~Adium@port375.ds1-hr.adsl.cybercity.dk) Quit (Ping timeout: 252 seconds)
  • [10:52:21] <lundmar> cjp, don't worry - thats what I do all the time. I just need to build some confidence here that latest actually works on the xM (I'm asking here since I don't even have HW yet!)

  • [13:48:08] <jwinnebeck> This is for Beaglebone
  • [13:48:26] <av500> yes
  • [13:48:30] <av500> i think thats a know issue
  • [13:48:38] <av500> unplug/replug does not work atm
  • [13:48:40] <av500> koen: ^^^^
  • [13:48:54] <jwinnebeck> Oh really, I was not able to research it. Well I tried 3 kernels, plug/replug works on one but not others
  • [13:49:17] <jwinnebeck> But on the kernel where it works, I am trying to use FTDI serial and it "craps out" constantly, but it works perfectly on the other kernels where I can't replug
  • [13:49:42] <jwinnebeck> I don't know if anyone is knowing about it or working on it where that fact would help them

  • [13:54:57] <woglinde> cool
  • [13:55:11] <jwinnebeck> I did read it, except that it works with one of the kernels, I thought maybe if it's a known issue someone is working on it and might want to know that
  • [13:55:16] <jwinnebeck> It's not a hardware issue
  • [13:55:23] <jwinnebeck> well it suggests that it's not
  • [13:55:37] <woglinde> thats why usb suckz
  • [13:55:43] <woglinde> only few doing it right
  • [13:55:46] <woglinde> in software
  • [13:55:53] <woglinde> and some suckz at hw
  • [13:56:10] <jwinnebeck> I've worked on other systems and the USB does suck, but the problems I have there is EMI/power/signalling
  • [13:57:24] <jwinnebeck> Until we build a cape the USB is the fastest way...
  • [13:57:25] <woglinde> av500 why need android more diskspace than oe?
  • [13:57:28] <woglinde> fastest way of what?
  • [13:58:15] <jwinnebeck> Adding hardware like CAN, wifi, bluetooth, serial, etc
  • [13:59:04] <jwinnebeck> there is no wifi/BT on the board, you can add a cape for it but obviously quickest way is plug in a wifi USB for prototyping
  • [13:59:25] <av500> woglinde: what?
  • [13:59:38] <av500> jwinnebeck: sure
  • [13:59:43] <av500> jwinnebeck: as said, its a know bug

  • [16:15:34] <mdp> mranostay, hobbyist boy scout merit badget :)
  • [16:16:41] <jwinnebeck> ShadowJK: Yeah the problem I had with ext3 is that the performance on SD/MMC was far far worse than ext2, because of journaling
  • [16:17:03] <jwinnebeck> but I think it was more than that, IIRC in ext3 there is a sort of "global lock" when committing the journal that doesn't happen in ext4
  • [16:17:12] <jwinnebeck> so there is this random blocking of things
  • [16:17:14] <mranostay> jwinnebeck: just don't power down incorrectly :)
  • [16:17:38] <jwinnebeck> Yeah in another embedded system we ran ext2 but we also had a UPS
  • [16:17:46] <av500> keep the rootfs in read-only mode
  • [16:17:47] <jwinnebeck> also other technique was to have OS on read-only partition and
  • [16:17:48] <jwinnebeck> yeah
  • [16:17:53] <jwinnebeck> put var on rw
  • [16:17:53] <ShadowJK> I've never seen any performance differencwe between ext2 and ext3, although I imagine if you had some really shitty card like Kingston there'd be difference between ext2 and ext3
  • [16:18:00] <jwinnebeck> and if I HAVE to blow away var, I just do it
  • [16:18:23] <jwinnebeck> Yeah maybe we did something wrong but it was horrible with ext3, we were using MySQL
  • [16:18:30] <jwinnebeck> flush times were in like 30-60 seconds with ext3
  • [16:18:31] <ShadowJK> Biggest issue is of course that a single 512byte write is just as expensive as a half megabyte write :)
  • [16:18:35] <jwinnebeck> and less than 1 second with ext2
  • [16:18:38] * Matt_O (~MattOwnby@216.160.243.228) Quit (Ping timeout: 240 seconds)
  • [16:18:46] <jwinnebeck> We were on a compactflash card running UDMA
  • [16:18:53] <jwinnebeck> it was about 10MB/sec write
  • [16:19:03] <jwinnebeck> I have a feeling it was the way MySQL does fsyncs
  • [16:19:20] <ShadowJK> Write speed is irrelevant
  • [16:19:26] <jwinnebeck> Because "normal" bopping around of the system like sftp etc didn't really affect ext2 vs ext3
  • [16:19:54] <jwinnebeck> Well what I mean is that the CF card was fastish but not extreme or anything
  • [16:20:01] <jwinnebeck> But yeah there is some latency/blocking thing or something
  • [16:20:07] <ShadowJK> Because it only applies to 100% pure sequential write. If your MySql is updating little things here and there it'll be slower than rewriting the entire file.
  • [16:20:09] <jwinnebeck> I read up on it
  • [16:20:13] <ka6sox> mranostay, there was at least 1 left :D
  • [16:20:38] <mranostay> ah what the hell it is only $70
  • [16:20:46] * mranostay pops out the credit card
  • [16:20:47] <jwinnebeck> But I wish I remember all I read, but I think I figured that it was probably due to a global atomic lock with sync so the throughput became very very low with mysql
  • [16:21:03] <ShadowJK> In fact, databases optimized for flash operate in something close to journal-only mode so that it only ever appends a file :)
  • [16:21:07] <jwinnebeck> I think MySQL fsyncs after every insert
  • [16:21:18] <jwinnebeck> Yeah I don't/didn't want to use MySQL at all
  • [16:21:23] <jwinnebeck> but it was existing solution
  • [16:21:32] <jwinnebeck> we actually didn't even need the DB, it was horrible
  • [16:21:38] <jwinnebeck> we just needed the replication logs :)
  • [16:21:41] <ShadowJK> It's not a lock. It's just the amount of random writes.
  • [16:21:43] <jwinnebeck> it was a write-only database
  • [16:22:04] <jwinnebeck> The replacement was using a flat file and appending to it
  • [16:22:15] <jwinnebeck> that doesn't have problem in ext3
  • [16:22:17] * ka6sox uses couchDB for most stuff stuff with nodeJS.
  • [16:22:34] <mdp> mranostay, cool..see you there then
  • [16:23:01] <ShadowJK> You get 4 IOPS on flash. A sync updates more than 4 things probably :)
  • [16:23:02] <jwinnebeck> problem is customers used to SQL...
  • [16:23:17] <jwinnebeck> so didn't switch to the flat file
  • [16:23:25] <jwinnebeck> :\
  • [16:23:37] <ShadowJK> (an SSD will give you about 40,000 IOPS)
  • [16:23:50] <jwinnebeck> Yeah our original system was an msystems 1GB SSD
  • [16:23:56] <jwinnebeck> but that system was from around 2003 or so
  • [16:23:59] <jwinnebeck> it was a $800 drive
  • [16:24:07] <jwinnebeck> it screamed
  • [16:24:24] <maluta> jkridner: I noted that /dev/graphics/fb0 didn't appears...
  • [16:24:33] <jwinnebeck> TBH I haven't seen a 1GB flash drive that performs as well as those SSDs did
  • [16:24:49] <jwinnebeck> real SSDs are big now in size and space
  • [16:24:51] <maluta> I've tried some variations for bootargs, only worked when I use: "... vram=1228800 omapfb.vram=0:1228800 omapfb.mode=dvi:1280x720MR-16@60 omapdss.def_disp=tv"
  • [16:25:29] <ShadowJK> Because they're optimized for cameras. Cameras write a 12megapixel image in one huge chunk, then update the FAT. The card only needs to handle one datastream at once
  • [16:25:30] <jwinnebeck> OK I'm getting off-topic, I was just curious why ext3 instead of 4
  • [16:25:33] <maluta> specially: omapdss.def_disp=tv (if I use =div fb0 aren't created)
  • [16:25:47] <jwinnebeck> I never tested ext4 but reading it, it sounded like it would have fixed the fsync problem with MySQL on flash
  • [16:25:52] <maluta> s/=div/=dvi/
  • [16:26:26] <jwinnebeck> We do data logging and I'm curious to use beaglebone for the same
  • [16:26:34] <jwinnebeck> because it costs less than 10% of the current solution
  • [16:26:44] <ShadowJK> I'm guessing because ext4 was too buggy at the time they made first image, and then it hasn't been updated since
  • [16:26:52] <maluta> jkridner: so I tried to run "androidvncserver_froyo" http://fpaste.org/7uU9/
  • [16:26:52] <jkridner> join me in #rowboat
  • [16:27:19] <ShadowJK> honestly, the problem is MySQL. It rapes even proper harddrives. Sqllite too
  • [16:27:41] <jwinnebeck> Yeah I just convinced myself I don't care because I remember the ext3 problem was with MySQL, and I have the power to finally kill MySQL from this thing once and for all
  • [16:27:50] <jwinnebeck> MySQL is horrible if the power goes out the whole table is shit
  • [16:28:00] <mranostay> ka6sox: ok 48 at most left now :)
  • [16:28:10] <jwinnebeck> And we're running an embedded system, not a server
  • [16:28:17] * ShadowJK remembers when firefox switched to sqlite, typing stuff into address bar caused a 2 second pause after each letter. Then they disabled fsync in sqlite and it became bearable
  • [16:28:18] <jwinnebeck> So I agree re: MySQL
  • [16:28:28] <ShadowJK> and that was on a proper fastc omputer with a proper harddrive
  • [16:28:36] <jwinnebeck> Yeah I looked at sqllite I really like it, but it has that flush problem too
  • [16:28:41] <jwinnebeck> And I remember that with firefox
  • [16:29:03] <jwinnebeck> Actually what pissed me off is that I was running an old/slow/loud HD
  • [16:29:10] <ShadowJK> Flat file, then convert to whatever customer wants somewhere else.
  • [16:29:15] <jwinnebeck> and when they swithced it does commits every time you make ANY CLICK anywhere

  • [16:31:09] <jwinnebeck> ShadowJK: yeah problem with customers is that when it's installed and alreayd working... which it was, it was slow but still fast enough to write data faster than it was coming it, so solutions like that tend to never change... if it ain't broke...
  • [16:31:23] <jwinnebeck> So even though it was horrific, it was good enough
  • [16:32:15] <jwinnebeck> Anyway, I've been absolutely impressed with the power and speed of the beaglebone for what it is
  • [16:32:18] <jwinnebeck> as well as the features
  • [16:32:26] <jwinnebeck> This is a game changer

  • [16:32:52] <CanyonMan> The sitara line is wonderful so far, and it's so much more accessible than omap is
  • [16:32:53] <av500> jwinnebeck: pah, it does not even decode HD
  • [16:32:53] <Mojito> The BeagleBone looks easier to get started with

  • [16:33:22] <av500> jwinnebeck: I'm running around headless :)
  • [16:33:41] <Mojito> For my project though I need Wifi and Audio, neither of which the BBone has
  • [16:33:47] <jwinnebeck> Yeah but
  • [16:33:51] <jwinnebeck> that's what we like about the bone
  • [16:34:02] <jwinnebeck> we're not Intel here we can't build a massive board
  • [16:34:12] <jwinnebeck> the ARM is simple enough to work with
  • [16:34:19] <CanyonMan> I found a module that you can buy in single piece quantities that uses the wifi/bluetooth chipset that's intended to be used by T.I.
  • [16:34:23] <jwinnebeck> simpler even than the OMAP as CanyonMan said
  • [16:34:27] <CanyonMan> What you need is just for somebody to put it on a CAP.
  • [16:34:29] <CanyonMan> CAPE.
  • [16:34:33] <jwinnebeck> yeah it is only like $30!
  • [16:34:36] <CanyonMan> I wonder how many people would be itnerested in that
  • [16:34:41] <ShadowJK> even if it decodes hd, the drivers and setting up always seem impossibly complex compared to, say, nvidia vdpau over on desktop
  • [16:34:48] <CanyonMan> because if enough people were itnerested I might start up a project on ....

  • [16:35:40] <CanyonMan> that's the module
  • [16:35:41] <Mojito> considering how tiny a wifi and BT chip is....
  • [16:36:08] <CanyonMan> or is it
  • [16:36:12] <CanyonMan> yeah taht's the one.
  • [16:36:23] <av500> thats the module on the panda
  • [16:36:28] <CanyonMan> That one does synchronization between the bluetooth and the 802.11 radio as well, so you can operate both of them simultaneously without interfering.
  • [16:36:28] <jwinnebeck> look at that, 32.55 in quantity 1
  • [16:36:38] <jwinnebeck> A normal person can buy that
  • [16:36:39] <CanyonMan> I don't know what a panda is, except the kind that eats bamboo
  • [16:36:47] <av500> pandaboard.org
  • [16:37:05] <CanyonMan> ah ok
  • [16:37:10] <jwinnebeck> waho!
  • [16:37:15] <jwinnebeck> there is an ICS build for panda
  • [16:37:26] <jwinnebeck> "PandaBoard is the only open community board supported 'out of the box'??by??Android 4.0" -- http://pandaboard.org/
  • [16:37:29] <av500> yes, since day one
  • [16:37:37] <av500> since google developed on the panda :)
  • [16:37:38] <CanyonMan> pandaboard = a lot for $179.
  • [16:37:42] <CanyonMan> i mean, it's a nice board for that.
  • [16:37:44] <jwinnebeck> wow it is $179
  • [16:37:59] <jwinnebeck> the bone with a cape will get near that
  • [16:38:09] <av500> panda is subsidized
  • [16:38:15] <jwinnebeck> What about the bone?
  • [16:38:16] <av500> the real BOM is more like $250
  • [16:38:23] <av500> the bone is not
  • [16:38:26] <jwinnebeck> ok
  • [16:38:26] <CanyonMan> oh geeze
  • [16:38:27] <av500> neither is the beagle
  • [16:38:36] <CanyonMan> so an OMAP44X has M3s in it instead of PRUs ?
  • [16:38:45] <av500> in a way yes
  • [16:38:49] <jwinnebeck> Yeah if one makes a product out of this... one cannot buy the panda
  • [16:38:57] <av500> the m3s are to handle the ISP and the IVAHD
  • [16:39:21] <CanyonMan> oh so on that particular board they aren't really usable for other stuff
  • [16:39:22] <CanyonMan> interesting.
  • [16:39:37] <CanyonMan> I hope I'm not making a mistake doing PRU development.
  • [16:39:45] <CanyonMan> In some ways I worry that I'm just locking myself into T.I.
  • [16:39:59] <av500> I dont see a future for PRU
  • [16:40:05] <CanyonMan> really
  • [16:40:11] <CanyonMan> because?
  • [16:40:18] <jwinnebeck> Is there a way to do real-time serial/gpio stuff without the PRUs?
  • [16:40:19] <CanyonMan> it will be supplanted by M0/M3 ?
  • [16:40:19] <av500> why not use some tiny arm core?
  • [16:40:26] <CanyonMan> yeah
  • [16:40:34] <av500> jwinnebeck: depends on your definition of realtime
  • [16:40:57] <CanyonMan> I kind of know what you mean. The PRU is pretty low power, and makes it easy to write extremely deterministic software
  • [16:41:03] <av500> use neutrinos if you need surreal time
  • [16:41:12] <jwinnebeck> protocol over RS485 where the framing is determined by the time between the bits
  • [16:41:22] <CanyonMan> but you can accomplish the same thing in M0 or M3 if you're careful, and then you can transpose whatever you've developed to future platforms, if - as you say - PRU is kind of on its way out
  • [16:42:07] <av500> CanyonMan: how did people handle that before PRU?
  • [16:42:18] <Mojito> Maybe the PRU is there to compete with Arduino stuff
  • [16:42:24] <av500> nah
  • [16:42:28] <CanyonMan> no
  • [16:42:34] <CanyonMan> the real reason the PRU is there is to reduce external hardware
  • [16:43:00] <av500> PRU = probably reduce units
  • [16:43:22] <CanyonMan> i mean
  • [16:43:39] <jwinnebeck> wait so if pandaboard does ICS
  • [16:43:41] <jwinnebeck> and HDMI
  • [16:43:49] <jwinnebeck> why should I not buy one and hook it up to my TV
  • [16:43:53] <jwinnebeck> it has wifi too
  • [16:43:55] <Mojito> If you start with a BeagleBone, then add all the extra stuff you need for wifi, etc, you may as well have started with a Panda in the first place
  • [16:44:11] <jwinnebeck> and BT, maybe useful for keyboard...
  • [16:44:17] <av500> yes
  • [16:44:24] <av500> and it has XMBC starting to work
  • [16:44:25] <CanyonMan> jwinnebeck: even at 9600bps, that's 104 uS per bit, if you need say 16x sampling then doing a software uart by bit banging with linux involved is not really practical in any sane way. It's just too fast.
  • [16:44:40] <CanyonMan> With the PRU you could do a bit banged UART at a few MHz fairly easily
  • [16:44:42] * jpsaman (~jpsaman@videolan/developer/jpsaman) has joined #beagle
  • [16:44:42] <av500> why would you do a sw UART?
  • [16:44:55] <CanyonMan> av500: specialized uarts
  • [16:44:58] <jwinnebeck> CanyonMan: Linux can't service interrupts in 100uS?
  • [16:45:13] <av500> who said linux btw?
  • [16:45:17] <CanyonMan> I'm sure it can, but what's the latency
  • [16:45:18] <av500> your M3 wont run linux
  • [16:45:26] <CanyonMan> no no we're getting all confused here
  • [16:45:27] <av500> or M0
  • [16:45:36] <av500> CanyonMan: that can *never* happen :)
  • [16:45:45] <CanyonMan> i thought he was asking about doing it in just the main CPU
  • [16:45:52] <jwinnebeck> I mean I can use the panda as a settop box for browser and photos and crap
  • [16:46:11] <av500> CanyonMan: even there you can do things, like use the FIQ outside of linux
  • [16:46:13] <jwinnebeck> CanyonMan: yeah I meant using the sitara for it
  • [16:46:21] <CanyonMan> I think an M0 or M3 core could do the same ething though. You'll get more bang per MHz out of the PRU, but the PRU is limited to 200 MHz and it's its own screwy assembly language
  • [16:46:31] <av500> its not set in stone that IRQs have to be handled by linux
  • [16:46:39] <CanyonMan> yeah
  • [16:47:00] <av500> we did IR receivers in linux by not handling it in linux
  • [16:47:04] <CanyonMan> so I think the PRU is incredibly useful (if that wasn't clear). I'm just bothered that it's really one-off
  • [16:47:21] <CanyonMan> and any knowledge I gain doing things in PRU isn't very transferrable
  • [16:47:46] <av500> well, since TI does not want people to use the PRU, it does not insprire confidence in its future

  • [16:48:21] <CanyonMan> The other use case that T.I. advertizes for the PRU is to do power management functions... more sophisticated than just the PMIC. But that's another job that could be handled easily by and m0 or m3 propertly tied into the main cpu
  • [16:48:31] <CanyonMan> wel let me ask you this
  • [16:48:36] <CanyonMan> PRUs came in with what, davinci right?
  • [16:49:00] <CanyonMan> and all those application specific processors for things like cell phones. So .... do OMAP based cell phones etc. make use of the PRU?
  • [16:49:22] <av500> ???
  • [16:49:26] <av500> they dont have thr PRU
  • [16:49:32] <av500> davinci has no PRU either

  • [16:51:03] <av500> these are not OMAPs :)
  • [16:51:17] <jwinnebeck> Well OK if you back up for a second, if you didn't use the PRU, what would you use to implement a custom UART?

  • [16:51:28] <av500> on a mobile phone?
  • [16:51:39] <jwinnebeck> no on a sitara, like the beaglebone

  • [17:05:51] <jwinnebeck> I just saw the video the guy is running ICS on his TV with it
  • [17:06:24] <jwinnebeck> I've was looking at things a lot more expensive than this to do the same
  • [17:06:41] <CanyonMan> av500: the thing about this uart is that it has to implement some funky timing requirements to detect message boundaries; on the transmit side it has to implement a collision avoidance and detection algorithm (multi-drop shared bus); and there's error detection that's beyond simple "framing error" type things
  • [17:06:45] <jwinnebeck> I mean just to use, not just for dev
  • [17:07:05] <CanyonMan> and since we can detect message boundaries, it's actually helpful to deliver complete messages to the main CPU rather than individual bytes (or blocks of bytes)
  • [17:08:40] <CanyonMan> some fo their demos for pru are weird. like building a delay line so you can make an audio reverb out of it

  • [18:25:06] <jsabeaudry> I am having trouble deciding between TI SDK, Angstrom and Arago as I am not really familiar with any of them. Anyone aware of a resource comparing the most popular OSes on the beagle?
  • [18:28:05] <jsabeaudry> How long does Ubuntu take to boot on the beaglebone?
  • [18:29:40] <mdp> Arago builds TI SDK???there are only two distros then in your list
  • [18:29:43] <denix> jsabeaudry: TI SDK is what Arago produces, where beagle is not the main supported platform.
  • [18:30:30] <mdp> beagleboard xm *is* an officially supported platform in the TI SDK
  • [18:30:44] <mdp> whatever that means :)
  • [18:31:23] <denix> I didn't say it's not supported, I said it's not a primary platform
  • [18:31:38] <mdp> we have a primary platform?
  • [18:32:29] <denix> I'd say beagle is a primary for angstrom :)
  • [18:32:31] <woglinde_> lol how the hell somebody checks that unnoticed in
  • [18:32:33] <woglinde_> ??????????????????<intent-filter>
  • [18:33:32] <woglinde_> all this nice android hackers
  • [18:34:34] <mdp> denix, beagleboard xm gets the exact same testing as all the other platform???though it doesn't have to have working PM to be released
  • [18:35:14] <denix> jsabeaudry: anyway, Arago serves needs of TI SDK, which has some specific requirements of being a showcase for TI EVM platforms
  • [18:35:31] * jay6981 (~Adium@38.114.132.193) has joined #beagle

  • [19:28:48] <jwinnebeck> jsabeaudry: I think I've settled on angstrom. I didn't get it at first because it didn't boot up for me with DHCP
  • [19:29:01] <jwinnebeck> But it looked like the most recent of them
  • [19:29:16] <jsabeaudry> jwinnebeck: oh ya the bug from 12-13 to 12-26 approximately
  • [19:29:23] <jwinnebeck> Although I have USB problems with that version that I didn't have with the older TI SDK 5.03.00 but 5.03.00 had more problems
  • [19:30:20] <jwinnebeck> jsabeaudry: What build are you using? I was using the TI SDK and what it built from source, but I found Angstrom-systemd-image-eglibc-ipk-v2011.11-core-beaglebone.rootfs.tar.bz2 16-Nov-2011 18:46 12M to be better
  • [19:30:30] <jwinnebeck> Which is what I am using now
  • [19:30:46] <jsabeaudry> jwinnebeck: Have you given a run to Android or Ubuntu? So many distributions to choose from!
  • [19:31:05] <jwinnebeck> jsabeaudry: I'm running headless on beaglebone so I'm not interested in those
  • [19:31:33] <jwinnebeck> ACtually I was trying to figure out how to get rid of all of the stuff from the full image, so I found that "rootfs"
  • [19:31:48] <jwinnebeck> which has very similar functionality to the "rootfs" from the TI SDK
  • [19:31:49] <jsabeaudry> jwinnebeck: Right now I'm using the cloud9 demo image from 12-26
  • [19:32:01] <jwinnebeck> Yeah that one is called "2011.12" the rootfs is 2011.11
  • [19:32:08] <jwinnebeck> Are you on bone or original beagle or XM?
  • [19:32:18] <jsabeaudry> jwinnebeck: On the bone
  • [19:32:31] <jwinnebeck> Yeah
  • [19:32:47] <jwinnebeck> I'm using the u-boot and MLO from the TI SDK though I couldn't download them from the http://angstrom.s3.amazonaws.com/demo/beaglebone/index.html page
  • [19:32:55] <jwinnebeck> That might have been why DHCP didn't work
  • [19:33:03] <jwinnebeck> I had to set up a uEnv.txt with ip_option=dhcp to get it
  • [19:33:20] <jwinnebeck> I should quantify "didn't work" I mean that it didn't come up in boot I had to go in with serial console and do it
  • [19:33:22] <jwinnebeck> dropbear still doesn't start
  • [19:33:33] <jwinnebeck> But I haven't heard of systemd until 2 days ago
  • [19:33:50] <jwinnebeck> And the TI SDK image was sysvinit
  • [19:33:54] <jsabeaudry> I'm currently setting up my system to build angstrom so that I can configure everything. Even on the lastest image I found I2C1 is not enabled
  • [19:34:18] <jwinnebeck> I haven't checked on hardware yet, do you know if dcan and such works on the angstrom kernel?
  • [19:34:30] <jsabeaudry> jwinnebeck: Yes I encoutered the same dhcp problem as you did, basically the eth0 interface was not up
  • [19:34:33] <jwinnebeck> It's the newest of the 3 I've tried though... except it's called "3.1.0+" whatever that means
  • [19:34:52] <jwinnebeck> jsabeaudry: Well mine comes up but there is a script busybox-udhcpc
  • [19:35:03] <jwinnebeck> and for some reason it greps /proc/cmdline for "ip=dhcp"
  • [19:35:09] <jwinnebeck> and if it doesn't see it, it doesn't run at all
  • [19:35:22] <jwinnebeck> But ip=dhcp makes the kernel I'm using not boot until dhcp comes up
  • [19:35:35] <jwinnebeck> So it's a stopgap measure for me until I can learn systemd enough to make my own scripts
  • [19:35:47] * Mojito (~Mojito@c-24-61-135-142.hsd1.nh.comcast.net) has left #beagle
  • [19:36:58] <jsabeaudry> jwinnebeck: hopefully in a few days I get learn enough to understand all that stuff, I played around with linux before but never so deep
  • [19:36:59] <jwinnebeck> I mean obviously I can run dhcp manually when it boots but not very useful unless you have serial console :)
  • [19:37:17] <jwinnebeck> I know more about Linux than I care to
  • [19:37:29] <jwinnebeck> I've done a lot of embedded stuff, but with ubuntu
  • [19:37:43] <jwinnebeck> queue the people who say it's not embedded because it's ubuntu and x86
  • [19:37:50] <jsabeaudry> jwinnebeck: Have you written drivers?
  • [19:37:52] <jwinnebeck> ... get over it everyone :)
  • [19:38:09] <jwinnebeck> No that's the part I don't know, one of my co-workers knows that
  • [19:38:29] <jwinnebeck> But I've built a few custom distributions from nothing
  • [19:38:37] <jwinnebeck> and I know way more about dpkg/apt than I care to
  • [19:38:56] <jwinnebeck> Since I ended up having to make something like 20+ debs
  • [19:39:42] <jwinnebeck> But in that case we were using ubuntu-minimal as a base and built from there. The other systems I've worked with were just kernel + busybox, which is annoying
  • [19:39:46] <jwinnebeck> because you have to build everything youself
  • [19:40:06] <jwinnebeck> at least busybox gives you a ton of stuff, I mean try to find the source for "top" "ps"
  • [19:40:38] <jwinnebeck> there's so many utilities when you think about it
  • [19:41:21] <jsabeaudry> jwinnebeck: Do you think it would be easier for a beginner to start from some demo image and strip it down or build himself?
  • [19:41:23] <CanyonMan> busybox's 'top' and 'ps' make me angry because they are so lame
  • [19:41:25] <jwinnebeck> My goal with the angstrom is to start from a minimal thing and then get just the ipkgs I want then make my own for my own software
  • [19:41:33] <CanyonMan> on that linuxsdk image i installed procps so I could have at least a top that doesn't suck
  • [19:41:51] <jwinnebeck> jsabeaudry: It depends on what you want to do, and what you care about (i..e space/boot time/etc)
  • [19:42:06] <jwinnebeck> IF the Cloud9 is like the full TI SDK one...
  • [19:42:10] <woglinde_> CanyonMan install htop
  • [19:42:13] <jwinnebeck> I mean the full TI SDK one has PHP and it starts 2 web servers on it
  • [19:42:14] <CanyonMan> busybox is a really great bundle of a lot of crappy applications
  • [19:42:19] <jwinnebeck> woglinde_: yeah we are using htop now
  • [19:42:29] <jwinnebeck> CanyonMan: you are out of date, the angstrom has htop in it :)
  • [19:42:32] <jsabeaudry> jwinnebeck: Same thing with Cloud9 except i think its 3 web servers
  • [19:42:32] <CanyonMan> woglinde_: yeah?
  • [19:42:32] <woglinde_> CanyonMan its small and does it think
  • [19:42:36] <jwinnebeck> CanyonMan: if you haven't used it, it's awesome
  • [19:42:43] <CanyonMan> i have NOT used it, but now I will
  • [19:42:57] <jwinnebeck> CanyonMan: it's on our bone right now, SSH is up
  • [19:43:18] <jwinnebeck> jsabeaudry: Yeah that's why I started with the Angstrom-systemd-image-eglibc-ipk-v2011.11-core-beaglebone.rootfs.tar.bz2
  • [19:43:24] <woglinde_> hm looks like openjdk is not enough for android
  • [19:43:26] <CanyonMan> oh HELLO color curses
  • [19:43:27] <jwinnebeck> But even that has more things on it than I want
  • [19:43:42] <jwinnebeck> However, it's not starting a zillion services
  • [19:44:00] <jwinnebeck> jsabeaudry: so I would start with that if you can. It has opkg set up so you can opkg install what you want
  • [19:44:05] <woglinde_> jwinnebeck start gnome and you have zillion services
  • [19:44:07] <CanyonMan> we can just superglue our usb device in so it can't be removed. ever.
  • [19:44:36] <jwinnebeck> woglinde_: well I don't have a display so I don't need gnome :)
  • [19:44:46] <jwinnebeck> All I want is dropbear (or openssh)!
  • [19:45:04] <woglinde_> dropbear is default
  • [19:45:14] <woglinde_> nearly on all images and distro which uses oe
  • [19:45:16] <jwinnebeck> But the rootfs isn't booting cleanly for me

  • [19:45:58] <jwinnebeck> woglinde_: I JUST learned about systemd's existance 2 days ago but I think it's because dropbear is not in multi-user.target.wants
  • [19:46:05] <jwinnebeck> I have to systemctl start dropbear.socket
  • [19:46:14] <jwinnebeck> then I can connect
  • [19:46:18] <woglinde_> hm that makes me wonder
  • [19:46:25] <jwinnebeck> But it complains
  • [19:46:28] <jwinnebeck> about configure.service not existing
  • [19:46:51] <woglinde_> does /etc/int.d/dropbear start not work?
  • [19:47:04] <jwinnebeck> That does but it runs dropbear daemon
  • [19:47:10] <jwinnebeck> it doesn't run it via systemd
  • [19:47:13] <woglinde_> yes
  • [19:47:13] <jwinnebeck> at least I don't think so
  • [19:47:18] <jwinnebeck> and yes that does work
  • [19:47:24] <jwinnebeck> that's what I did until I realized that's the wrong way
  • [19:47:25] <woglinde_> you want dropbear
  • [19:47:30] <woglinde_> no
  • [19:47:33] <jwinnebeck> because systemd is The Way Of The Future so
  • [19:47:37] <woglinde_> when no systemd file is there
  • [19:47:38] <jwinnebeck> I wanted to start dropbear.socket
  • [19:47:49] <woglinde_> it should use old sysv style
  • [19:47:50] <woglinde_> hm hm
  • [19:47:56] <jwinnebeck> systemd is on this image...
  • [19:48:02] <jwinnebeck> I read about it, it sounds cool
  • [19:48:07] <jwinnebeck> I have only worked with upstart and sysvinit
  • [19:48:08] <woglinde_> o.O
  • [19:48:14] <jwinnebeck> I didn't know there was something else
  • [19:48:16] <vexorg> woglinde_, updated the recipe and it worked! thanks for your help :)
  • [19:48:24] <woglinde_> vexorg fine
  • [19:48:37] <vexorg> also subscribed to oe-core, will lurk for a while to learn how others post first
  • [19:49:07] <woglinde_> read the archive
  • [19:49:13] <woglinde_> use proper git-format
  • [19:49:22] <woglinde_> and dont forget signed-off
  • [19:49:31] <jwinnebeck> woglinde_: there is a file /etc/systemd/system/sockets.target.wants/dropbear.socket
  • [19:49:35] <jwinnebeck> that's a symlink
  • [19:49:40] <jwinnebeck> Not sure why that means dropbear doesn't start
  • [19:50:08] <jwinnebeck> I haven't found what the "starting place" is for systemd
  • [19:50:09] <woglinde_> jwinnebeck sure because koen made sure that a sshd is working
  • [19:50:14] <jwinnebeck> like how do I know what target is run on boot?
  • [19:50:24] <woglinde_> so I wonder why it dont start up
  • [19:50:29] <jwinnebeck> Not sure
  • [19:50:35] <woglinde_> try to remove this symlink
  • [19:50:44] <woglinde_> and systemd will use the sysvinit script
  • [19:50:47] <jwinnebeck> I see messages on serial console when I boot about dropbear
  • [19:50:55] <jwinnebeck> ok
  • [19:50:59] * dalton (c88146fc@gateway/web/freenode/ip.200.129.70.252) has joined #beagle
  • [19:51:05] <jwinnebeck> I also had to run dropbearkey.service manuall ytoo
  • [19:51:21] <jwinnebeck> But I am using rootfs 2011.11
  • [19:51:25] <jwinnebeck> there is a Cloud9 2011.12
  • [19:51:29] <jwinnebeck> is there a newer rootfs?
  • [19:51:45] <jwinnebeck> If I "bitbake systemd-image" does that build me taht rootfs.tgz?
  • [19:52:31] * Tartarus (trini@pixelshelf.com) has joined #beagle

  • [19:53:12] <Tartarus> hey woglinde_
  • [19:53:22] <Tartarus> forgot to jump back in here when znc died :)
  • [19:53:23] <jwinnebeck> Yeah, like you asid you expected it to work, so do I... I wanted to double check that I'm using the latest image
  • [19:54:38] <woglinde_> than use the cloud9 image

  • [19:56:30] <jwinnebeck> woglinde_: I could but I don't need to start 500 services, I suppose I could try it just for comparison purposes
  • [19:57:01] <jwinnebeck> it looked like better to start with rootfs and build up than try to figure out how to remove a bunch of stuff
  • [19:57:37] <jwinnebeck> I tried that on the TI SDK 5.03.01 image and opkg segfaulted on me then the opkg repository got corrupted and I was wedged; no install or uninstall
  • [19:57:52] * peabody124 (~peabody12@connect.tuebingen.mpg.de) Quit (Quit: peabody124)
  • [19:58:14] <jwinnebeck> Boot time is a important thing for me, if I can boot under 10 seconds it is good, under 5 and it is awesome
  • [19:58:30] <jwinnebeck> it looks very possible, there are a few werid hangs in the boot process
  • [19:58:47] <jwinnebeck> the rootfs takes sometimes over a minute to boot
  • [19:58:48] <jwinnebeck> not sure why
  • [19:59:22] <jwinnebeck> kernel boots in something like 1.5 seconds though which is awesome, I should need more than a few seconds past that
  • [19:59:27] <jwinnebeck> shouldn't need more I mean
  • [20:00:02] <dalton> Hello... I am trying to create a development environment for angstrom, in my ubuntu... so, I cloned: git clone git://git.angstrom-distribution.org/setup-scripts... and ran these commands: ./oebb.sh config beagleboard, ./oebb.sh update and ./oebb.sh bitbake virtual/kernel
  • [20:00:31] <woglinde_> dalton yes
  • [20:00:39] <dalton> does have any way of see if the installation is ok?
  • [20:01:00] <Tartarus> jwinnebeck: probably takes long on an unclean restart and journal gets replayed, etc
  • [20:01:01] <woglinde_> if no error occurs the final image should be okay
  • [20:01:23] <woglinde_> its located under build/tmp-yourfooarch/deploy/images
  • [20:01:30] <woglinde_> ah
  • [20:01:32] <woglinde_> sorry
  • [20:01:34] <woglinde_> only kernel
  • [20:01:40] <woglinde_> but kernel will land there too
  • [20:01:50] <woglinde_> hms
  • [20:02:04] <woglinde_> how do I make clean for subfolder in android
  • [20:04:34] <dalton> woglinde_, can you tell me, please, what I need to develop, in ubuntu, for angstrom in beagleboard, besides the commands I said/ran?
  • [20:05:43] <woglinde_> dalton I can not tell you what to develop
  • [20:06:00] <woglinde_> what you want to develop is your own ideas
  • [20:06:12] <dalton> sorry
  • [20:06:14] <woglinde_> I can help you when something dont works as expected
  • [20:06:24] <dalton> I did not express me well
  • [20:07:14] <jwinnebeck> Tartarus: there seems to be a 30 second pause after the rootfs is mounted and systemd is already running, but it's possible yes.
  • [20:07:59] <dalton> I know what I have to develop... =) the right question was: can you tell me what is needed for development in that environments? did you understand me now? ( I was not clear before)
  • [20:08:00] <woglinde_> jwinnebeck hm than read lennards blog posts about systemd
  • [20:08:32] <woglinde_> jwinnebeck and watch koen's talk on booting under 2seconds to console with systemd from elce
  • [20:08:44] <jwinnebeck> woglinde_: Only I've read so far is http://0pointer.de/blog/projects/systemd.html and also some of systemd man pages
  • [20:09:20] <dalton> I will have to read some data from sensors, through serial or usb port, at beagleboard... but I dont know how to develop, because I dont have experience and I dont know some sdk (like adb for android and its plugin for eclipse)
  • [20:09:23] <jwinnebeck> woglinde_: I do want to see that talk... I don't know who koen is or elce but I will try google
  • [20:09:33] <woglinde_> jwinnebeck -> http://free-electrons.com/blog/elce-2011-videos/
  • [20:09:34] <jwinnebeck> dalton: what language?
  • [20:09:37] <woglinde_> search for koen
  • [20:09:52] <jwinnebeck> dalton: I'll probably be booted from this channel but I am using Java
  • [20:09:55] <woglinde_> jwinnebeck without koen you proably wouldnt have systemd on your bone
  • [20:10:10] <dalton> for angstrom?
  • [20:10:18] <woglinde_> and without me you wouldnt have java for your bone
  • [20:10:26] <jwinnebeck> Well I'm using Oracle Java
  • [20:10:30] <jwinnebeck> is there working open source Java
  • [20:10:38] <woglinde_> sure openjdk
  • [20:10:49] <jwinnebeck> our software is Java which has restricted us for a long time to x86 "embedded"
  • [20:11:13] <jwinnebeck> Well but we tried to get openjdk + zerovm working in ubuntu arm and it was a disaster
  • [20:11:16] <jwinnebeck> just crashes
  • [20:11:21] <woglinde_> hehe
  • [20:11:26] <jwinnebeck> Without JIT, it is useless to run our software
  • [20:11:31] <jwinnebeck> Is SharkVM working?
  • [20:11:32] <woglinde_> hm
  • [20:11:34] <dalton> the problem is that my experience is in high level... so low level for me its complicated... I think that for development with angstrom I will use C, right?
  • [20:11:47] <woglinde_> you could hire me over my company
  • [20:11:48] <woglinde_> haha
  • [20:11:51] <jwinnebeck> dalton: Well you can use just about anoything. Heck my bone came with friggin PHP on it
  • [20:11:56] <jsabeaudry> jwinnebeck: Interesting, have you looked into faster load times for the JVM? I was interested in targetting it
  • [20:11:59] <jwinnebeck> I almost cried
  • [20:12:10] <woglinde_> jwinnebeck I could help you getting it run to do some evals
  • [20:12:16] <jsabeaudry> jwinnebeck: We are thinking about adding some NVRAM so that it loads faster
  • [20:12:17] <jwinnebeck> jsabeaudry: unfortunately load times on Java is pointless
  • [20:12:45] <jsabeaudry> jwinnebeck: How is system boot time pointless?
  • [20:12:57] <jwinnebeck> What I mean is that Java starts too slow without AOT and even then slow
  • [20:12:59] <jwinnebeck> so my idea
  • [20:13:01] <woglinde_> bah stupid android
  • [20:13:02] <jwinnebeck> ARM is low power
  • [20:13:12] <jwinnebeck> The best x86 system we've gotten is like 10W
  • [20:13:14] <woglinde_> even with oracle jdk it dont get its right
  • [20:13:24] <jwinnebeck> this bone it uses about 2.5-3W
  • [20:13:34] <jwinnebeck> it may be low power enough to never shut it down ever
  • [20:13:37] <jwinnebeck> then there is no boots
  • [20:13:51] <jwinnebeck> but kernel for bone doesn't support CPU freq or suspend to RAM but TI says "planned"
  • [20:14:03] <jwinnebeck> I hope it comes, becaue suspend to RAM is the holy grail for me
  • [20:14:05] <jwinnebeck> I think
  • [20:14:11] <mdp> RSN
  • [20:14:17] <jsabeaudry> jwinnebeck: Yes but for development I still wait 50 seconds everytime I start a jvm....
  • [20:14:28] <dalton> woglinde_, but... to read data from sensors through serial/usb port at beagleboard, maybe its better to program in low level with C (I dont have experience with this), right? Or do you suggest me another language?
  • [20:14:28] <jwinnebeck> Well develop on desktop :)
  • [20:14:39] <jwinnebeck> dalton: what sensors...?
  • [20:14:57] <jwinnebeck> dalton: I do monitoring software in JAva
  • [20:15:10] <woglinde_> dalton depends on the sensors
  • [20:15:14] <jsabeaudry> jwinnebeck: What do you use to call ioctl?
  • [20:15:28] <woglinde_> koen and jkdridner even use javascript to do it
  • [20:15:30] <jwinnebeck> jsabeaudry: C code, but you can get around it
  • [20:15:39] <jwinnebeck> I mean we know C, we can do C if we have to
  • [20:15:43] <jwinnebeck> you might need C
  • [20:15:45] <ds2> JNI baby
  • [20:15:47] <jsabeaudry> jwinnebeck: You call your C Libs using JNI?
  • [20:16:02] <ds2> rub the java mug so you can make wishes to the JNI
  • [20:16:09] <jwinnebeck> Well currently we have a daemon that runs in C that provides a socket
  • [20:16:23] <jwinnebeck> also there are some drivers that have a /dev/ interface that is text
  • [20:16:27] <woglinde_> jsabeaudry java can open files
  • [20:16:27] <jwinnebeck> in that case you can use Java directly
  • [20:16:30] <jwinnebeck> for example
  • [20:16:35] <woglinde_> so you can open all files in /sys
  • [20:16:39] <jsabeaudry> ah yes god bless sysfs drivers!
  • [20:16:41] <woglinde_> and read stuff yourself
  • [20:16:46] <jwinnebeck> Yeah you can do a lot with "text" files
  • [20:16:47] <ds2> just have a JNI setup that loads a .so file and calls main ;)
  • [20:17:02] <woglinde_> ds2 even use jna
  • [20:17:04] <jwinnebeck> Or one can use JNA
  • [20:17:04] <ds2> instant java program ;)
  • [20:17:14] <woglinde_> good
  • [20:17:24] <jwinnebeck> Anyway, yes we do native code but this program runs x86 embedded and x86 desktop and also hopefulyl arm
  • [20:17:27] <jsabeaudry> But JNA is slow, or so I've heard?
  • [20:17:29] <jwinnebeck> actually my program already is running on ARM now
  • [20:17:33] <jwinnebeck> because java runs on bone
  • [20:17:35] <jwinnebeck> so my program runs on bone
  • [20:17:37] <woglinde_> jwinnebeck so are you intrested in getting your program run under bone?
  • [20:17:41] <jwinnebeck> Yeah I am
  • [20:17:46] <jwinnebeck> very much
  • [20:18:02] <dalton> jwinnebeck: like density and acidity... I have to get the data and send them to a server...
  • [20:18:05] <woglinde_> okay dont know yet if koen builds packages for the bone too
  • [20:18:17] <jwinnebeck> We've tried like every year to run on ARM and it hasn't worked
  • [20:18:23] <jwinnebeck> but Oracle has J2SE now for ARM
  • [20:18:29] <jwinnebeck> and it actually runs really well
  • [20:18:34] <jwinnebeck> I'm running <10% CPU
  • [20:18:36] <woglinde_> ah okay
  • [20:18:37] <jwinnebeck> on the bone!
  • [20:18:39] <jwinnebeck> But
  • [20:18:46] <jwinnebeck> it costs $ of course
  • [20:18:49] <woglinde_> how the hell it runs under bone
  • [20:18:51] <jwinnebeck> But it's worth it
  • [20:18:56] <jwinnebeck> what do you mean how does it run
  • [20:19:00] <ds2> the j2se for ARM licensing from oracle blows
  • [20:19:02] <jwinnebeck> it's a C program compiled for armv7a

  • [20:19:17] <dalton> can you suggest me some tutorials about development (hands on) with angstrom?
  • [20:19:17] <jwinnebeck> Well we're about to talk to Oracle next week on that... maybe we find it is bad
  • [20:19:19] <woglinde_> sure but not with the oe/angstroem toolchain
  • [20:19:26] <jwinnebeck> Well it runs
  • [20:19:31] <jwinnebeck> It was the first thing I did
  • [20:19:32] <ds2> they want royalties for everything
  • [20:19:34] <woglinde_> jwinnebeck okay try the following
  • [20:19:42] <jwinnebeck> If this doesn't run Java, the bone is uselss to me
  • [20:19:46] <woglinde_> jwinnebeck install the cloud9 image
  • [20:19:49] <jwinnebeck> the ONLY thing I want to do is run a JVM
  • [20:19:52] <woglinde_> opkg update
  • [20:19:55] <ds2> jwinnebeck: consider gcj?
  • [20:20:03] <woglinde_> opkg list | grep openjdk
  • [20:20:17] <woglinde_> opkg install openjdk stuff
  • [20:20:18] <jwinnebeck> gcj is classpath I was hoping when openjdk happened that they would get it with gcj
  • [20:20:21] <jwinnebeck> gcj is good for nothing
  • [20:20:28] <ds2> gcj compile to native code
  • [20:20:30] <jwinnebeck> woglinde_: I am running my own angstrom is that OK?
  • [20:20:38] <jwinnebeck> I do have opkg working
  • [20:20:50] <woglinde_> jwinnebeck you need the official angstroem mirrors
  • [20:21:12] <woglinde_> but dont know if koen put the ipkg's already there
  • [20:21:12] <jwinnebeck> I'm using http://feeds.angstrom-distribution.org/feeds/core/ipk/eglibc/armv7a/base for example
  • [20:21:18] <jwinnebeck> I did opkg list
  • [20:21:24] <jwinnebeck> no openjdk... but I forgot update!!!
  • [20:21:25] <jwinnebeck> let me try
  • [20:21:34] <jsabeaudry> ya its called openjdk6-jdk
  • [20:21:47] <jwinnebeck> it is there!
  • [20:21:47] <woglinde_> otherwise set up a devevn with setup-script
  • [20:21:52] <woglinde_> okay try it
  • [20:21:56] <jwinnebeck> Which VM?
  • [20:21:59] <jwinnebeck> does shark actually work
  • [20:22:01] <woglinde_> install all
  • [20:22:02] <jwinnebeck> if it does, that's what I want
  • [20:22:03] <jwinnebeck> ok
  • [20:22:13] <woglinde_> proably not
  • [20:22:20] <woglinde_> but we are working on it
  • [20:22:27] <woglinde_> you can choose the vm
  • [20:22:34] <jwinnebeck> OK
  • [20:22:38] <jwinnebeck> I have run openjdk on android
  • [20:22:40] <jwinnebeck> it didn't go well
  • [20:22:52] <woglinde_> with java -server == zero , java -shark, java -cacao or java -jamvm
  • [20:22:53] <jwinnebeck> that was from ubuntu chroot on android
  • [20:22:57] <jwinnebeck> ok
  • [20:23:27] <woglinde_> cacao was fast
  • [20:23:34] <jwinnebeck> I love Java
  • [20:23:35] <woglinde_> but maybee works not with all apps
  • [20:23:41] <jwinnebeck> Yeah I'll see
  • [20:23:50] <woglinde_> haha and give me the money instead of oracle
  • [20:24:03] <jwinnebeck> Yeah we're at the point we've given up and ready to pay $$$
  • [20:24:09] <jwinnebeck> but we are a university
  • [20:24:12] <woglinde_> oh
  • [20:24:14] <woglinde_> okay
  • [20:24:22] <woglinde_> thought was commercial
  • [20:24:30] <jwinnebeck> But the product has been used in commerical and military
  • [20:24:31] <woglinde_> okay bye me a beer
  • [20:24:32] <jsabeaudry> jwinnebeck: I hate java but I also want a JVM, before christmas I ran a complete clojure web stack on the bone, can't remember which vm it was
  • [20:24:48] <woglinde_> jwinnebeck can you tell me what it is?
  • [20:25:15] <woglinde_> a nice I get some feedback for my work
  • [20:25:34] <jwinnebeck> http://www.lockheedmartin.com/products/EmbeddedPlatformLogisticsSystem/index.html is older
  • [20:25:46] <jsabeaudry> woglinde_: you are working on openjdk for arm?
  • [20:26:17] <jwinnebeck> # java -version
  • [20:26:18] <jwinnebeck> dl failure on line 696Error: failed /usr/lib/jvm/java-6-openjdk/jre/lib/arm/shark/libjvm.so, because libLLVMARMCodeGen.so: cannot open shared object file: No such file or directory
  • [20:26:43] <jwinnebeck> java -version -zero works
  • [20:26:52] <jwinnebeck> but I can't run just "java"
  • [20:27:36] <jwinnebeck> Anyway we do research but the products get spun out
  • [20:27:59] <woglinde_> jwinnebeck ah okay so its the older stuff
  • [20:28:11] <woglinde_> I already fixed this in my overlay
  • [20:28:14] <jwinnebeck> so it kind of sucks we have to pretend like we want to buy a million but don't actually have the power heh
  • [20:28:29] <jwinnebeck> Well it's 6b18-1.8.11
  • [20:28:47] <jwinnebeck> but I thknk opkg gave me the old one
  • [20:28:54] <woglinde_> no
  • [20:29:03] <woglinde_> koen didnt make newer packages yet
  • [20:29:04] <jwinnebeck> I see 6b18-1.8.11-r11.0 and 6b18-1.8-r10.7.6
  • [20:29:13] <jwinnebeck> but it didn't install the 1.8.11
  • [20:29:22] <woglinde_> uhm
  • [20:29:22] <jwinnebeck> is that the newer one?
  • [20:29:25] <woglinde_> use the 1.8.11
  • [20:29:31] <jwinnebeck> how? I did this:
  • [20:29:35] <jwinnebeck> # opkg install openjdk-6-jre openjdk-6-vm-cacao openjdk-6-vm-shark openjdk-6-vm-zero
  • [20:29:47] <jwinnebeck> when I did opkg list I saw 2 versions of each
  • [20:30:01] <jwinnebeck> err wait a second let me double check
  • [20:30:15] <jwinnebeck> I'm sorry I think I did get the 1.8.11
  • [20:30:21] <woglinde_> yes
  • [20:30:24] <woglinde_> try java -cacao
  • [20:30:29] <woglinde_> and see if its working
  • [20:30:39] <jwinnebeck> opkg list-installed | grep openjdk ---> openjdk-6-jre - 6b18-1.8.11-r11.0 (and more)
  • [20:30:50] <jwinnebeck> it does
  • [20:30:54] <jwinnebeck> and so does java -zero
  • [20:31:03] <jwinnebeck> cacao is JIT on some platforms?
  • [20:31:24] <woglinde_> yes it has jit for arm
  • [20:31:36] <jwinnebeck> I guess shark is default but is missing a so for some reason
  • [20:31:42] <jwinnebeck> is that my fault or the package's?
  • [20:31:46] <woglinde_> my fault
  • [20:31:54] <jwinnebeck> let me try editing my launch script and run my app
  • [20:32:00] <woglinde_> didnt fixed the linker option
  • [20:32:04] <woglinde_> but its llvm2.9 anyway
  • [20:32:07] <woglinde_> which dont works
  • [20:32:39] <jwinnebeck> even if we run openjdk is it really possible to use it without paying to the Oracle overlords?
  • [20:33:00] <woglinde_> yes
  • [20:33:14] <woglinde_> look at the license
  • [20:33:21] <jwinnebeck> Yeah it's GPL... But
  • [20:33:29] <jwinnebeck> Oracle also says that the MySQL protocol is GPL
  • [20:33:34] <woglinde_> oracle gave it out
  • [20:33:36] <jwinnebeck> therefore it's not possible to build non-GPL software against it
  • [20:33:46] <jwinnebeck> And they also sue Android
  • [20:33:48] <jwinnebeck> which is BSD
  • [20:33:51] <jwinnebeck> sorry
  • [20:33:52] <Mare13h> jsabeaudry: about 20 seconds from cold to login prompt
  • [20:33:52] <jwinnebeck> Apache
  • [20:34:08] <woglinde_> no the suit the java stuff google stole
  • [20:34:18] <woglinde_> but I think oracle will not win
  • [20:34:22] <jwinnebeck> Oracle says that a program that can use MySQL from Java must be GPL...
  • [20:34:30] <jwinnebeck> so you have to pay them
  • [20:34:38] <jwinnebeck> even though you don't even need mysql driver on classpath to compile
  • [20:34:44] <woglinde_> whats wrong with GPL?
  • [20:34:49] <jsabeaudry> Mare13h: Sweet is that with the standard Kingston Class 4 MicroSD ?
  • [20:34:56] <jwinnebeck> We're not open source :\
  • [20:35:03] <woglinde_> GPL dont says you have to give source everyone
  • [20:35:12] <woglinde_> give the source to your customers and finde
  • [20:35:14] <Mare13h> I used a different one but I think it was a class 4
  • [20:35:15] <woglinde_> args fine
  • [20:35:19] <jwinnebeck> just to people to who you distribute
  • [20:35:19] <ds2> just avoid oracle stuff
  • [20:35:22] <ds2> easiest way
  • [20:35:26] <jwinnebeck> I know
  • [20:35:29] <jwinnebeck> well I'm not in charge
  • [20:35:42] <ds2> or pay through the nose for one of the other independant vms
  • [20:35:46] <jwinnebeck> personally I would rather be open source and sell our services
  • [20:35:49] <jwinnebeck> but not my choice
  • [20:36:05] <jwinnebeck> Yeah avoiding Oracle is what I want to do at all costs
  • [20:36:13] <jwinnebeck> also why I want to ditch MySQL and never use it again
  • [20:36:15] <ds2> the look at the other VMs
  • [20:36:18] <jwinnebeck> Which I've already done
  • [20:36:23] <jwinnebeck> Well I'm runnig zero now
  • [20:36:25] <jwinnebeck> thanks to woglinde_
  • [20:36:26] <woglinde_> I wouldnt use mysql at all
  • [20:36:32] <jwinnebeck> I'm watching Java running now on bone
  • [20:36:35] <jwinnebeck> with zero
  • [20:36:39] <jwinnebeck> I am collecting data
  • [20:36:41] <woglinde_> jwinnebeck I meant is your app running
  • [20:36:45] <jwinnebeck> yes
  • [20:36:47] <ds2> there is one that shows up at trade show for embedded stuff
  • [20:36:47] <jwinnebeck> with zero
  • [20:36:50] <woglinde_> thats what I am intressted in
  • [20:36:51] <woglinde_> cool
  • [20:36:54] <ds2> they give away orange pens but I can't remember their name
  • [20:36:58] <woglinde_> and with cacao too?
  • [20:37:03] <jwinnebeck> haven't tried cacao
  • [20:37:09] <jwinnebeck> Do you need JSA with zero/caco?
  • [20:37:16] <woglinde_> jsa?
  • [20:37:19] <jwinnebeck> or is that hotspot only
  • [20:37:36] <jwinnebeck> the classes.jsa you get from java -Xdump:shared
  • [20:37:39] <woglinde_> zero is hotspot with java asm byte code
  • [20:37:43] <jwinnebeck> it's like a precompiled rt.jar
  • [20:37:49] <jwinnebeck> so you don't have to do classloading
  • [20:37:52] <woglinde_> hm dont know offhand
  • [20:37:56] <jwinnebeck> it was a feature in Sun Java 1.5+
  • [20:38:07] <woglinde_> ah I think thats not working with cacao
  • [20:38:14] <woglinde_> but I am not sure
  • [20:38:16] <woglinde_> just measure
  • [20:38:23] <jwinnebeck> 13% CPU
  • [20:38:27] <woglinde_> but I bet oracle jdk will win
  • [20:38:29] <jwinnebeck> that's not bad but slower than oracle
  • [20:38:43] <jwinnebeck> hmm 24% now
  • [20:38:47] <jwinnebeck> let me try cacao!
  • [20:38:58] <jwinnebeck> still, look at the bone man 24% to run a Java program
  • [20:39:11] <jwinnebeck> that's plenty fast enough
  • [20:39:14] <woglinde_> thats not bad
  • [20:39:55] <jsabeaudry> Mare13h: Good stuff, thanks for the input
  • [20:40:12] <jwinnebeck> startup time 22s with zero
  • [20:40:18] <Mare13h> I've been impressed with Ubuntu on it so far
  • [20:40:47] <Mare13h> Its pretty responsive and has a good collection of packages, though it is missing node
  • [20:40:52] <woglinde_> hm thats not bad either for zero
  • [20:41:03] <jwinnebeck> cacao crashes
  • [20:41:17] <jwinnebeck> LOG: [0x454d2470] JVM_MaxObjectInspectionAge: IMPLEMENT ME!
  • [20:41:26] <jwinnebeck> LOG: [0x4006a000] JVM_DumpThreads: IMPLEMENT ME!
  • [20:41:36] <woglinde_> hm okay
  • [20:41:40] <woglinde_> sorry
  • [20:41:43] <jwinnebeck> yeah
  • [20:41:45] <jwinnebeck> it's not your fault
  • [20:41:51] <jwinnebeck> but it's similar to what I've seen before
  • [20:41:55] <jwinnebeck> shark can't even run hello world
  • [20:42:02] <woglinde_> it can
  • [20:42:02] <jsabeaudry> I'm annoyed by the fact that emacs is not on angstrom...
  • [20:42:05] <woglinde_> with llvm 2.7
  • [20:42:10] <jsabeaudry> Is it on ubuntu-arm?
  • [20:42:11] <jwinnebeck> zero runs but slowly... although this is a lot faster than I have seen in the past
  • [20:42:16] <woglinde_> okay
  • [20:42:19] <woglinde_> than try jamvm
  • [20:42:20] <jwinnebeck> This is similar to what I saw in android
  • [20:42:21] <Mare13h> I'll have a look, 1 mo
  • [20:42:25] <jwinnebeck> Well zero might be good enough
  • [20:42:45] <jwinnebeck> what is the story on jam
  • [20:42:53] <woglinde_> I heard ubuntu choosed jamvm as vm on arm for next releases
  • [20:43:25] <jwinnebeck> I don't see an openjdk-6-vm-jamvm
  • [20:43:37] <jwinnebeck> oh I find it
  • [20:43:44] <woglinde_> and there is some rumour google used a lot of stuff from jamvm in first android releases
  • [20:43:56] <jwinnebeck> Well I've been wanting to try this program on android for a long time
  • [20:44:00] <jwinnebeck> just no budget for me to do it
  • [20:44:08] <jwinnebeck> and no motivation to do it on my own clock
  • [20:44:17] <woglinde_> sure
  • [20:44:17] <jwinnebeck> 95% of what I've written should run in android
  • [20:44:21] <jwinnebeck> in dalvikvm
  • [20:44:28] <Mare13h> Yeah, emacs and emacs23 packages
  • [20:44:29] <jwinnebeck> But also openjdk runs on android too
  • [20:44:47] <jwinnebeck> openjdk didn't exist when dalvik was started I wonder what android would hav ebeen like with openjdk
  • [20:44:48] <jsabeaudry> Mare13h: Joy!
  • [20:44:54] <jwinnebeck> google could have made that VM nice
  • [20:45:03] <jwinnebeck> or use dalvik VM with openjdk classpath
  • [20:45:22] <Mare13h> heh, infact there are about 50 packages with emacs in the description
  • [20:45:30] <ka6sox> jsabeaudry, you can opkg install emacs ?
  • [20:45:31] <Mare13h> Lots of plugins
  • [20:46:22] <jsabeaudry> ka6sox: Unknown package emacs
  • [20:46:22] <jwinnebeck> hmm so I tried my program with jamvm, I get error from SAX
  • [20:46:33] <jwinnebeck> oh jamvm is using GNU classpath
  • [20:46:41] <CanyonMan> boo
  • [20:46:43] <jwinnebeck> that won't work that I'm pretty sure of I've tried classpath in the past
  • [20:46:46] * l4 (~marius@93.207.38.86.mobile.mezon.lt) Quit (Quit: l4)
  • [20:46:58] <jwinnebeck> Hi CanyonMan, woglinde_ has been helping me with Java stuff
  • [20:47:03] <jwinnebeck> I didn't know openjdk is here
  • [20:47:12] <jwinnebeck> zerovm is working but slower than snoracle VM
  • [20:47:16] <ka6sox> interesting
  • [20:47:24] <CanyonMan> An embedded person who doesn't have java? That doesn't sound right ...
  • [20:47:31] <ka6sox> I should look @ what narcissus has.
  • [20:47:31] * CanyonMan looks at woglinde_ suspiciously
  • [20:47:36] <jwinnebeck> I know
  • [20:47:37] <ka6sox> maybe different name.
  • [20:47:49] <jwinnebeck> you meant hate not have
  • [20:47:58] <ka6sox> I wonder if its the nox version
  • [20:48:13] <jwinnebeck> Well I always say I work on "embedded" systems because what I am calling embedded is twice as powerful as my desktop in 1999
  • [20:48:16] <jwinnebeck> so it still embedded?
  • [20:48:20] <jwinnebeck> Dunno
  • [20:48:49] <jsabeaudry> I can find it here: http://www.angstrom-distribution.org/repo/?pkgname=emacs
  • [20:48:52] <jwinnebeck> woglinde_: So I guess the question is what is the story on shark?
  • [20:49:04] <jsabeaudry> But not on the bone
  • [20:49:21] <woglinde_> yeah I am in all
  • [20:49:39] <woglinde_> jwinnebeck I will getting it run with xrandby together
  • [20:49:50] <jwinnebeck> we meet with oracle bent over next week :(
  • [20:49:51] <woglinde_> or maybe switching back to llvm2.7
  • [20:49:55] <jwinnebeck> I mean I'm bent over
  • [20:49:57] <jwinnebeck> oracle is not
  • [20:50:03] <woglinde_> so whats with jamvm now?
  • [20:50:09] <jsabeaudry> It is probably the nox version because there are explicit x11 versions on the package browser
  • [20:50:21] <jwinnebeck> jamvm is it using GNU classpath or openjdk
  • [20:50:23] <woglinde_> oh okay
  • [20:50:24] <woglinde_> sax
  • [20:50:35] <woglinde_> jamvm should use the openjdk
  • [20:50:40] <woglinde_> in this setup
  • [20:50:44] <jwinnebeck> org.jdom.JDOMException: http://apache.org/xml/features/validation/dynamic feature not supported for SAX driver gnu.xml.stream.SAXParser
  • [20:50:44] <woglinde_> or do use jamvm
  • [20:50:56] <woglinde_> directly
  • [20:51:00] <jwinnebeck> I did directly
  • [20:51:02] <woglinde_> no
  • [20:51:03] <jwinnebeck> how do I use with openjdk
  • [20:51:04] <woglinde_> as vm
  • [20:51:09] <woglinde_> install the vm
  • [20:51:21] <CanyonMan> haha #beagle is the wrong place to ask this, but then again, somebody else metnioned panda board earlier so .... does anybody know if there's an inexpensive eval board for qcom snapdragons out there right now?
  • [20:51:28] <jwinnebeck> I did opkg list | grep jamvm and saw only package "jamvm"
  • [20:52:08] <woglinde_> jwinnebeck hm okay
  • [20:52:17] <jwinnebeck> is there supposed to be an openjdk-6-vm-jamvm
  • [20:52:19] <jwinnebeck> I did not see that
  • [20:52:33] <woglinde_> jwinnebeck did you compiled already something for angstroem?
  • [20:52:43] <woglinde_> with bitbake?
  • [20:52:48] <jwinnebeck> woglinde_: I haven't compiled anything other than what the TI SDK gave me
  • [20:52:54] <woglinde_> hm okay
  • [20:52:58] <jwinnebeck> oh I almost ran bitbake
  • [20:53:02] <woglinde_> I could compile you something
  • [20:53:06] <woglinde_> okay
  • [20:53:18] <woglinde_> than you could use my meta-java layer
  • [20:53:18] <jwinnebeck> I did the ./oebb.sh config beaglebone
  • [20:53:26] <woglinde_> when you are using oe-core
  • [20:53:49] <jwinnebeck> Yeah I don't know anything more than the script listed on this page: http://angstrom.s3.amazonaws.com/demo/beaglebone/index.html
  • [20:53:50] <ka6sox> jsabeaudry, did you do a opkg update; opkg install foo?
  • [20:53:57] <CanyonMan> hm why did somebody from T.I. tech support just say this to me: "Good luck on the Angstrom port there! That???s pretty an un chartered territory for us here."
  • [20:54:11] <woglinde_> yeah thats funny
  • [20:54:12] <jsabeaudry> ka6sox: yup
  • [20:54:13] <jwinnebeck> bitbake didn't run because I was as root and the TI SDK screwed my perms
  • [20:54:20] <jwinnebeck> I need to rerun git clone as my user
  • [20:54:21] <woglinde_> with the diffrent devisions in TI
  • [20:54:44] <ka6sox> wierd...
  • [20:54:45] <CanyonMan> woglinde_: i was just asking if it's really the armv7a core ... The reason I asked is that the AM335x docs don't specifically say
  • [20:54:47] <jsabeaudry> ka6sox: I'll do it again just to be sure, that was before christmas
  • [20:55:02] <jwinnebeck> Ok let's say that I can bitbake then what are you saying I can get from that? I could build your openjdk packages or something?
  • [20:55:08] <woglinde_> right
  • [20:55:09] <ka6sox> jsabeaudry, I know there were repo issues areound that time.
  • [20:55:16] <CanyonMan> and the -A extensions are there to support very large memory ... yet the sitara can only address 1GB so I was curious is it REALLY v7a
  • [20:55:19] <CanyonMan> but they say yes indeed it is.
  • [20:55:19] <jsabeaudry> ka6sox: same thing
  • [20:55:28] <jsabeaudry> ka6sox: Unknown package emacs
  • [20:55:28] <ka6sox> okay
  • [20:55:47] <CanyonMan> Also, I don't like that name Sitara. It reminds me of that guy from that awful band from the 70s.
  • [20:55:48] <jwinnebeck> woglinde_: what does your company offer, btw
  • [20:55:49] <woglinde_> jwinnebeck you need to add this layer
  • [20:55:50] <woglinde_> https://github.com/woglinde/meta-java
  • [20:56:00] <ka6sox> I'll have to go look @ packages.gz in the repo we are using and find out why.
  • [20:56:12] <woglinde_> jwinnebeck support for openjdk inside openembedded
  • [20:56:15] <ka6sox> (on the server end)
  • [20:56:21] <jwinnebeck> oh ok
  • [20:56:28] <woglinde_> but we are german based
  • [20:56:31] <jsabeaudry> ka6sox: This : http://feeds.angstrom-distribution.org/feeds/core/ipk/eglibc/armv7a/machine/beaglebone/Packages.gz ?
  • [20:56:35] <jwinnebeck> yeah I'm in the US
  • [20:56:39] <woglinde_> but meta-java I did in my spare time
  • [20:56:41] <jwinnebeck> but maybe it doesn't matter
  • [20:56:42] <jwinnebeck> ok
  • [20:57:05] <woglinde_> do you know how to add a layer?
  • [20:57:14] <jwinnebeck> I bet if I open oebb.sh I will find out
  • [20:57:18] <ka6sox> jsabeaudry, yes, but I want to look at the US repo and see if it matches the EU repo.
  • [20:57:20] <jwinnebeck> I need to do the git checkout properly
  • [20:57:25] <jwinnebeck> let me get that started first
  • [20:57:41] <woglinde_> no
  • [20:57:45] <jwinnebeck> oh?
  • [20:57:45] <woglinde_> edit conf/bblayers.conf
  • [20:57:57] <woglinde_> setup-script will do this for you
  • [20:58:01] <jwinnebeck> oh ok
  • [20:58:03] <jsabeaudry> ka6sox: Ah ok, how can I tell which of the two I'm using?
  • [20:58:37] <jwinnebeck> is it safe for me to remove the crap I don't care about, like meta-gpe and meta-intel?
  • [20:58:40] <woglinde_> hm wait
  • [20:58:45] <ka6sox> you probalby can't as I'm sure its a rotator.
  • [20:58:46] <woglinde_> sure
  • [20:59:26] <woglinde_> okay forgot how setup-scripts checkout the stuff
  • [20:59:26] <jwinnebeck> ah screw it I don't need more stress I'll just add to EXTRALAYERS
  • [20:59:31] <woglinde_> so do it manually
  • [20:59:35] <jwinnebeck> oh?
  • [20:59:41] <woglinde_> got to source
  • [20:59:43] <woglinde_> and clone it
  • [20:59:48] <woglinde_> and add it in the layer
  • [20:59:52] <woglinde_> conf
  • [20:59:59] <woglinde_> bitbake openjdk-6
  • [21:00:02] * emeb_mac (~ericb@ip72-223-81-94.ph.ph.cox.net) has joined #beagle
  • [21:00:17] <woglinde_> but you will have to set a few variables in local.conf
  • [21:01:16] <jwinnebeck> ok give me a second to wrap my head around it, I'm a SVN guy this is my first thing here. So you are saying don't edit anymore the setup-scripts/conf/bblayers.conf?
  • [21:01:19] <woglinde_> http://pastebin.com/xqJm1pYK
  • [21:01:21] <jwinnebeck> ok
  • [21:01:33] <jwinnebeck> :( pastebin is down, lol
  • [21:01:33] <woglinde_> the variables you need to set
  • [21:01:38] <woglinde_> ?
  • [21:01:39] <jwinnebeck> there it does
  • [21:01:42] <jwinnebeck> it gave me the lolcat
  • [21:01:45] <jwinnebeck> it said "heavy load"
  • [21:01:46] <jwinnebeck> haha
  • [21:01:49] <jwinnebeck> but I refresh and got it
  • [21:01:53] <woglinde_> okay
  • [21:02:13] <woglinde_> jwinnebeck build will last around 2 hours or morw
  • [21:02:21] <woglinde_> depending on your machine
  • [21:02:23] <jwinnebeck> :( that's what I was afraid of ha
  • [21:02:40] <jwinnebeck> That's why I didn't run the systemd-image

  • [21:03:39] <CanyonMan> it'll last him a lot longer beacuse he's doing it in a vbox
  • [21:03:49] <jwinnebeck> I do have a VM
  • [21:04:06] <jwinnebeck> But first I need to grep all of this heh
  • [21:05:40] <dalton> woglinde_, how can I use the "setup-scripts" (Angstrom) after installed?
  • [21:06:52] <woglinde_> its in the little tutorial
  • [21:07:06] <woglinde_> in two ways
  • [21:07:18] <woglinde_> but I prefere the direct bitbake way
  • [21:07:24] <woglinde_> so I source the env file
  • [21:07:56] <woglinde_> than MACHINE=foomymachine bitbake package_image_or_what_ever I want
  • [21:10:10] <woglinde_> hm looks like I need the genlock stuff for my android foo
  • [21:10:35] <woglinde_> jwinnebeck when all is build copy over the ipk's or setup your own repo
  • [21:11:08] <jwinnebeck> Yeah I haven't started it yet I think I screwed something up. Does it build its own cross-compiler (or get one)?
  • [21:11:21] <jwinnebeck> I was doing a clean thing, starting over
  • [21:11:22] <woglinde_> hm dont know what TI SDK does
  • [21:11:30] <woglinde_> angstroem build its own
  • [21:11:42] <jwinnebeck> and then it gives me errors about directories from where I tried to build it before, but that's in a different user's account so how the heck does it know about that
  • [21:11:54] <jwinnebeck> paths in the TI SDK
  • [21:12:07] <jwinnebeck> I don't see any vars except QMAKESPEC reference that
  • [21:12:14] <jwinnebeck> I did this:
  • [21:12:29] <jwinnebeck> git clone git://git.angstrom-distribution.org/setup-scripts; cd setup-scripts; git checkout origin/oe-core -b oe-core; /oebb.sh config beaglebone
  • [21:12:40] <jwinnebeck> and the oebb failed
  • [21:12:45] <jwinnebeck> I did edit the layers.txt first tho
  • [21:13:03] <jwinnebeck> added meta-java,https://github.com/woglinde/meta-java,master,HEAD
  • [21:13:18] <woglinde_> ah
  • [21:13:21] <jwinnebeck> I should try really clean to make sure I didn't do something lame
  • [21:13:27] <woglinde_> whats failing?
  • [21:13:43] <jwinnebeck> Ok I rm -rf'd everything gonna try over
  • [21:13:49] <woglinde_> ,)
  • [21:14:32] <jwinnebeck> wow what the hello
  • [21:14:38] <jwinnebeck> I dun get it man

  • [21:14:56] <jwinnebeck> that's the TI SDK I installed as root (beacsue you have to)
  • [21:15:00] <jwinnebeck> I'm not running as root or anything
  • [21:15:08] <jwinnebeck> how does it even KNOW about that path

  • [21:16:17] <woglinde_> lol
  • [21:16:29] <jwinnebeck> looking at the script to see wher eit is getting these paths from
  • [21:16:39] <jwinnebeck> oh what the hell
  • [21:16:45] <jwinnebeck> it makes something called ~/.oe

  • [21:18:14] <xenland> jsabeaudry: oh thanx
  • [21:18:32] <xenland> How do i know which pin I'm talking to?
  • [21:18:42] <xenland> echo 1 = pin 1?

  • [21:18:44] <jwinnebeck> OK deleting that ~/.oe works
  • [21:18:59] <woglinde_> no 1 is on or off
  • [21:19:01] <woglinde_> ups
  • [21:19:02] <jsabeaudry> xenland: Oh my bad I though you were talking about the user led
  • [21:19:14] <woglinde_> 1 == on gpio 0 == gpio off
  • [21:19:30] <jsabeaudry> xenland: look into /sys/class/gpio
  • [21:19:30] <xenland> woglinde: gotcha
  • [21:19:46] <jsabeaudry> xenland: to toggle gpio pins
  • [21:20:53] <woglinde_> for other gpios read the kernel doku
  • [21:21:00] <woglinde_> maybee for some you need to export them first
  • [21:21:23] <xenland> jsabeaudry: that reminds me of this tutorial: http://bbfordummies.blogspot.com/2009/07/1.html I couldn't figure out how to select the pins i wanted tho
  • [21:21:33] <xenland> scince that tut is for beagleboard
  • [21:21:51] <xenland> (I'm using BeagleBone)
  • [21:22:39] <xenland> jsabeaudry: hey your LED command worked!
  • [21:22:46] <xenland> for the on board led anyways
  • [21:22:51] <xenland> thats always nice to see something work for once
  • [21:23:43] <xenland> :D Time to make a tut!
  • [21:24:24] <mdp> yeah, for actual led class stuff you need to see the documentation in the s/w
  • [21:24:31] <mdp> https://github.com/beagleboard/linux/blob/v3.1-meta-ti-r2f+gitr1d84d8853fa30cf3db2571a5aec572accca4e29d/arch/arm/mach-omap2/board-am335xevm.c#L745

  • [21:30:12] <jwinnebeck> ok finally I think I am building something...
  • [21:30:46] <woglinde_> cool
  • [21:30:58] <jwinnebeck> It's building "pseudo" now
  • [21:30:58] <woglinde_> now wait 5 hours
  • [21:31:01] <woglinde_> yes
  • [21:31:04] <muriani> haha
  • [21:31:10] <muriani> always withthe pseudo building
  • [21:31:24] <jwinnebeck> how much disk space will I need for this
  • [21:31:27] <jwinnebeck> I hope my VM is not too small
  • [21:31:27] <muriani> woglinde_: building for beagle now. We'll see how it goes.
  • [21:31:50] <woglinde_> jwinnebeck hm around 20 gigs
  • [21:31:54] <jwinnebeck> hahaha
  • [21:31:59] <jwinnebeck> well then
  • [21:32:01] <woglinde_> with rm_works inherit
  • [21:32:03] <jwinnebeck> I better cancel this out
  • [21:32:07] <muriani> lol
  • [21:32:11] <jwinnebeck> I have 2 G free
  • [21:32:14] <woglinde_> oh
  • [21:32:21] <woglinde_> that will not work
  • [21:32:26] <woglinde_> sorry
  • [21:32:32] <jwinnebeck> wow I guess I need a real linux box
  • [21:32:32] <woglinde_> make it 30 for safte
  • [21:32:35] <woglinde_> safety
  • [21:32:56] <jwinnebeck> I traded my life for an SSD here with this machine I got an SSD but it's only 120GB maybe that was a mistake
  • [21:33:08] <jwinnebeck> of course it's OK for me to spend 20 hours working around a $50 problem here
  • [21:33:15] <jwinnebeck> and we charge $100+ an hour
  • [21:33:22] <muriani> yeah.. SSD is nice, but sometimes you need rooom
  • [21:33:22] <jwinnebeck> but don't buy anything!
  • [21:33:46] <jwinnebeck> So then can I ask what bitbake systemd-image would do?
  • [21:33:49] <woglinde_> .o(100 at university)
  • [21:33:56] <woglinde_> not possible in germany
  • [21:34:05] <woglinde_> sure
  • [21:34:10] <jwinnebeck> what does that build
  • [21:34:18] <woglinde_> it is building a stock image with systemd included
  • [21:34:27] <woglinde_> you can go to sources
  • [21:34:32] <jwinnebeck> is it a replacement for the Angstrom-systemd-image-eglibc-ipk-v2011.11-core-beaglebone.rootfs.tar.bz2 I got from beaglebone site?
  • [21:34:43] <woglinde_> and do find -name "*systemd-image*"
  • [21:34:44] <jwinnebeck> or does it make the cloud9?
  • [21:34:48] <woglinde_> and look into that file
  • [21:35:11] <woglinde_> I think that was build with systemd-image goal
  • [21:35:19] <jwinnebeck> woglinde_: to build your openjdk-6 do I only need to add to sources/layers.txt?
  • [21:35:30] <jwinnebeck> In the end I got Nothing PROVIDES 'openjdk-6'
  • [21:35:35] <jwinnebeck> do I have to touch bblayers.txt?
  • [21:35:57] <jsabeaudry> I beleive it is openjdk6-jdk
  • [21:36:04] <jwinnebeck> crap I said MACHINE=beagleboard I wanted beaglebone
  • [21:36:04] <jsabeaudry> no?
  • [21:36:06] <jwinnebeck> what a dumbass
  • [21:36:08] <woglinde_> yes you need add it
  • [21:36:27] <woglinde_> jwinnebeck no problem the only differ in kernel
  • [21:36:31] <woglinde_> userspace is the same
  • [21:36:33] <jwinnebeck> ok
  • [21:36:38] <woglinde_> so no other arch
  • [21:37:10] <woglinde_> if you dont add the source-folder to the layers the file inside will not be parsed
  • [21:37:34] <jwinnebeck> I put this to EXTRALAYERS: ${TOPDIR}/sources/meta-java
  • [21:37:40] <jwinnebeck> wher eis where the git clone is
  • [21:38:29] <woglinde_> that looks good
  • [21:38:30] <jwinnebeck> I might need to build this on CanyonMan's monstrous machine later :)
  • [21:38:42] <woglinde_> what does he has?
  • [21:38:47] <jwinnebeck> I can at least watch this till my disk is full
  • [21:38:53] <woglinde_> lol
  • [21:38:54] <jwinnebeck> I think dual raid 1 1TB drives
  • [21:39:02] <woglinde_> dont waste your time with watching
  • [21:39:02] <jwinnebeck> and ubuntu as primary OS
  • [21:39:22] <jwinnebeck> well pseudo build only took a little bit :)
  • [21:39:32] <woglinde_> pseudo is fast

  • [21:39:36] <woglinde_> to build yes
  • [21:39:41] <woglinde_> gm djlewis
  • [21:39:49] <jwinnebeck> ha OK
  • [21:40:03] <djlewis> hello again ... having nameserver issues here :(
  • [21:40:48] <muriani> that's fun.
  • [21:40:58] <muriani> Had to deal with that with a client this morning
  • [21:41:01] <djlewis> yeah, my irc was still working but that was it.
  • [21:41:09] <muriani> "I can't access the internet!"
  • [21:41:40] <jwinnebeck> I like it when they say "the internet is down" because they can't get to e-mail
  • [21:41:45] <jwinnebeck> yes, the entire internet, it is down
  • [21:41:50] <djlewis> major disaster whan that happens to people that dont need the internet for their work
  • [21:42:11] <djlewis> s/whan/when
  • [21:43:57] <djlewis> like, i am on dsl at home, my phone was dead for over a week and I didnt know it cause my dsl was working fine :)
  • [21:44:06] <djlewis> I dont get many calls
  • [21:44:12] <woglinde_> djlewis ip-phone
  • [21:44:12] <jwinnebeck> So basically is bitbake compiling all of the packages needed for openjdk to compile that's why it needs to compile openssl-native and more?
  • [21:44:15] <woglinde_> and cellphone
  • [21:44:15] <woglinde_> haha
  • [21:44:27] <woglinde_> jwinnebeck yes
  • [21:44:35] <woglinde_> around 2900 targets
  • [21:44:40] <woglinde_> for openjdk-6
  • [21:44:41] <djlewis> I ca see two cell towers east and west of me but is is very unreliable at my home
  • [21:44:41] <jwinnebeck> well it's doing 3440 tasks
  • [21:44:46] <woglinde_> hm okay
  • [21:44:54] <jwinnebeck> that is crazy maybe I just use zero and go home
  • [21:45:04] <woglinde_> djlewis wrong provider
  • [21:45:12] <jwinnebeck> but really what am I getting in the end? Just the most recent version of your openjdk stuff?
  • [21:45:19] <woglinde_> yes
  • [21:45:21] <djlewis> not my phone, a freebie from the company
  • [21:45:22] <woglinde_> and jamvm
  • [21:45:24] <jwinnebeck> BTW good work on this though for what I've seen so far
  • [21:45:37] <jwinnebeck> Maybe we can free ourselves from the oracle devil
  • [21:45:43] <woglinde_> and shark with llvm 2.8
  • [21:45:47] <woglinde_> which may work
  • [21:45:48] <jwinnebeck> ohhhhh
  • [21:45:52] <jwinnebeck> shark... yummy
  • [21:45:54] <djlewis> I quit paying for apersonal cell phone years ago.
  • [21:46:00] <woglinde_> for one floatingpoint example it didnt
  • [21:46:01] <djlewis> dont want it
  • [21:46:13] <woglinde_> but I will figure it out with xrandby next-week
  • [21:46:16] <jwinnebeck> oh I use floating point a lot :\
  • [21:46:26] <jwinnebeck> are you just a builder or are you actually hacking on the VM code?
  • [21:46:32] <woglinde_> maybee its working with neon
  • [21:46:40] <woglinde_> depends
  • [21:46:44] <woglinde_> mostly builder
  • [21:46:50] <jwinnebeck> well bone has neon
  • [21:46:57] <woglinde_> but I made the whole stuff working under uclibc
  • [21:47:09] <jwinnebeck> uclibc we used that once some years ago
  • [21:47:12] <jwinnebeck> ended up just going to glibc
  • [21:47:18] <jwinnebeck> because "embedded" isn't emebdded anymore
  • [21:47:20] <woglinde_> uclibc is often faster
  • [21:47:25] <jwinnebeck> our "embedded" system has 1GB of RAM in it
  • [21:47:32] <jwinnebeck> Really, we didn't see that
  • [21:47:34] <woglinde_> and build time is 5th of glibc
  • [21:47:38] <jwinnebeck> if anything uclibc was slower
  • [21:47:43] <jwinnebeck> build time, I can see that for sure
  • [21:47:55] <woglinde_> than try to build all with uclibc
  • [21:48:08] <jwinnebeck> is this going to build the eglibc chain or uclibc chain?
  • [21:48:16] <jwinnebeck> how do I select that
  • [21:48:31] <woglinde_> TCLIBC=uclibc in front of bitbake
  • [21:48:38] <jwinnebeck> what's default?
  • [21:48:41] <woglinde_> eglibc
  • [21:48:43] <jwinnebeck> ok
  • [21:48:56] <woglinde_> bah this stupid android stuff
  • [21:49:06] <jwinnebeck> hey at least I'm not trying to compile ICS...
  • [21:49:09] <jwinnebeck> :)
  • [21:49:25] <jwinnebeck> I can't imagine a compiler taking 16GB
  • [21:49:34] <jsabeaudry> Is there a way to specify MACHINE=beaglebone in one of the config files not to have to type it nefore every ./oebb command?
  • [21:49:46] <jwinnebeck> Well I only had to run oebb once
  • [21:49:56] <jwinnebeck> then it told me to source ~/.oe/...
  • [21:50:01] * maluta (~maluta@maxtrack-F4-0-3-gacc04.bhe.embratel.net.br) Quit (Quit: Lost terminal)
  • [21:50:02] <jwinnebeck> some file in there (I tab-complete it)
  • [21:50:07] <jwinnebeck> then you can just run bitbake
  • [21:50:15] <jwinnebeck> I bet you could put MACHINE in there too
  • [21:50:20] <jwinnebeck> well I don't see why not
  • [21:50:25] <jwinnebeck> it's just an env
  • [21:50:28] <woglinde_> you can put MACHINE in local.conf too
  • [21:50:33] <jwinnebeck> oh
  • [21:50:43] <jsabeaudry> jwinnebeck: I'm following http://www.angstrom-distribution.org/building-angstrom
  • [21:51:01] <djlewis> OE, i have to re learn it every time i try to use it :(
  • [21:51:05] <jwinnebeck> Yeah the oebb script output that message to me
  • [21:51:07] <jsabeaudry> jwinnebeck: Perhaps there is a better resource I am not aware of?
  • [21:51:08] <jwinnebeck> told me not to use it
  • [21:51:13] <jwinnebeck> that's where I learned it from
  • [21:51:29] <woglinde_> lol
  • [21:51:36] <woglinde_> no
  • [21:51:51] <jwinnebeck> well it gives a warning when you run oebb it says "btw you can source this script and just run bitbake directly"
  • [21:51:57] <jsabeaudry> woglinde_: Ok I put MACHINE = "beaglebone" in local.conf
  • [21:52:00] <jwinnebeck> Anyway, I ran out of disk space so I call this build a success
  • [21:53:11] <jwinnebeck> I need to take a break anyway
  • [21:53:23] <jwinnebeck> I was supposed to do something else thsi afternoon but the bone keeps drawing me in
  • [21:53:25] <woglinde_> sure
  • [21:53:29] <woglinde_> tell me on monday
  • [21:53:35] <woglinde_> or sunday
  • [21:53:36] <jwinnebeck> Yeah I will try to find a place to build this
  • [21:53:39] <jwinnebeck> maybe my personal machine at home
  • [21:53:58] <jwinnebeck> let it run overnight
  • [21:54:07] <woglinde_> thats a good idea
  • [21:54:14] <woglinde_> as long as it not fails somewhere
  • [21:54:18] <jwinnebeck> Yeah I know
  • [21:54:20] <jwinnebeck> that's always the fear
  • [21:54:23] <woglinde_> do you have fast internet?
  • [21:54:25] <woglinde_> at home
  • [21:54:39] <jwinnebeck> 10mbit
  • [21:54:40] <woglinde_> it needs to download some stuff
  • [21:54:42] <jwinnebeck> cable model
  • [21:54:42] <woglinde_> okay
  • [21:54:51] <jwinnebeck> Yeah it downloads from the git clones
  • [21:55:07] <woglinde_> no
  • [21:55:09] <woglinde_> sources
  • [21:55:19] <woglinde_> or depends
  • [21:56:14] <jwinnebeck> sad when my home box > work box
  • [21:57:17] <woglinde_> that shouldnt happen
  • [21:57:20] <woglinde_> hw is cheap
  • [21:57:25] <jwinnebeck> I know
  • [21:57:37] <jwinnebeck> but it took us 2 years to convince our boss to let us buy beagle
  • [21:57:43] <woglinde_> uhm
  • [21:57:43] <jwinnebeck> I don't get it
  • [21:58:03] <woglinde_> so he tooks all the money himself
  • [21:58:19] <jwinnebeck> No, it's just a beaucratic nightmare to submit a purchase order sometimes
  • [21:58:24] <jwinnebeck> beacuse it has to all be signed off
  • [21:58:30] <jwinnebeck> I can go into a closet and nap for 2 hours and no one will notice

  • [21:59:10] <jwinnebeck> it's a dual core pentium 4
  • [21:59:13] <jwinnebeck> yes a pentium 4
  • [21:59:18] <jwinnebeck> it has 6GB of RAM
  • [21:59:23] <jwinnebeck> because I begged for 4GB more
  • [21:59:27] <jwinnebeck> it came with 2GB
  • [21:59:40] <jwinnebeck> and it only has like 160GB of drive space

  • [22:00:10] <jwinnebeck> Actually as far as orgs go, except for the money, this one is GREAT
  • [22:00:14] <jwinnebeck> I mean really great
  • [22:00:20] <jwinnebeck> anything else I have carte blanche
  • [22:00:26] <jwinnebeck> no firewalls, etc
  • [22:00:30] <jwinnebeck> well what I mean is
  • [22:00:33] <jwinnebeck> it's a university
  • [22:00:42] <jwinnebeck> so it's not like there's crazy proxies and stuff
  • [22:00:50] <jwinnebeck> we still have firewall like a normal person

  • [22:19:24] <jwinnebeck> aholler: given that we are using 3.1.0+ do you suggest ext4? my intuition tells me yes

  • [22:29:06] <jwinnebeck> I haven't used screen in lyaers
  • [22:29:12] <jwinnebeck> But if this build is going to go all night
  • [22:29:16] <jwinnebeck> I need to move my session around
  • [22:29:21] <jwinnebeck> thankfully I remembered screen
  • [22:29:30] <woglinde> ;)

  • [22:29:42] <woglinde> lol
  • [22:29:43] <jwinnebeck> There was a day I didn't know any unix stuff

  • [22:29:51] <woglinde> yeah
  • [22:29:54] <mdp> jwinnebeck: fwiw, ti sdk for am37x/am35x parts is still on a stone age kernel ??? only bone is recentish
  • [22:29:57] <woglinde> but they day ended in 96
  • [22:30:07] <woglinde> with irix 5.2
  • [22:30:19] <jwinnebeck> mdp: well I'm starting to get the impression that I don't want to use the TI SDK anymore
  • [22:30:31] <jwinnebeck> with this angstrom stuff it looks better than anything from TI
  • [22:30:36] <jwinnebeck> so right now I'm not seeing the point anymore
  • [22:30:40] <woglinde> jwinnebeck haha so koen win over denix again
  • [22:30:44] <mdp> jwinnebeck: depends on the part is all
  • [22:30:46] * woglinde runs
  • [22:30:46] <ds2> there is nothing wrong with older kernels if it works.
  • [22:30:57] <ds2> if you want the latest kernel, then you will never get anything done.
  • [22:31:02] <jwinnebeck> Well the TI SDK kernel is 3.1.0 anyway
  • [22:31:04] <jwinnebeck> I'm using bone
  • [22:31:17] <jwinnebeck> but the angstrom setup seems a lot better
  • [22:31:45] <mdp> exactly, because am35x/37x are a disaster in mainline, the only place to get mostly working system suspend is in those .32/.37 kernels
  • [22:31:45] <jwinnebeck> Uhm does bitbake run jove
  • [22:31:46] <CanyonMan> the one thing about the kernel though is that, sooner or later, we're going to need the DCAN driver and that wasn't in the 5.03 ti sdk
  • [22:32:03] <jwinnebeck> Oh... maybe we do care then?
  • [22:32:05] <mdp> so for many people they are stuck there
  • [22:32:11] <CanyonMan> I'm not really sure.
  • [22:32:15] <jwinnebeck> we care about dcan also suspend to RAM
  • [22:32:18] <CanyonMan> But I don't realy want to have to personally splice dcan in
  • [22:32:33] <jwinnebeck> my bitbake crashed... JOVE CRASH!! (code 1; last errno 10)

  • [22:45:18] <jwinnebeck> I'll try changing that to bash
  • [22:45:45] <jwinnebeck> nope that didn't work
  • [22:45:49] * brijesh_ (~bksingh@nat/ti/x-vvzqemmhsasxdhef) Quit ()
  • [22:45:52] <woglinde> hm I should switch it back to dash
  • [22:45:58] <woglinde> and fix all the bashims stuff
  • [22:46:22] <jwinnebeck> do I need /bin/sh as bash?
  • [22:46:28] <jsabeaudry> jwinnebeck: What is the package you are trying to bitbake again?
  • [22:46:36] <jwinnebeck> openjdk-6
  • [22:46:37] <jwinnebeck> but
  • [22:46:42] <jwinnebeck> it is building automake at the point it fails
  • [22:46:42] <woglinde> jwinnebeck there maybee still bashims somewhere
  • [22:47:02] <woglinde> jwinnebeck as I said edit Makefile
  • [22:47:03] * jpsaman (~jpsaman@videolan/developer/jpsaman) Quit (Quit: Leaving)
  • [22:47:08] <woglinde> and remove the emcas crap
  • [22:47:11] <jwinnebeck> Ok I will try to find it
  • [22:49:22] <jwinnebeck> OK found it
  • [22:49:24] <jwinnebeck> what is it supposed to be
  • [22:49:54] <jwinnebeck> what part is the bashism
  • [22:50:37] <jwinnebeck> yeah
  • [22:50:39] <jwinnebeck> when I run emacs
  • [22:50:41] <jwinnebeck> it runs jove
  • [22:50:43] <jwinnebeck> that's odd
  • [22:50:56] <woglinde> it runs the script
  • [22:50:57] <jwinnebeck> but this isn't my machine :)
  • [22:51:07] <woglinde> look what is happening in the script
  • [22:51:09] <jwinnebeck> I mean that line it runs /bin/bash directly
  • [22:51:15] <woglinde> yes
  • [22:51:28] <woglinde> elisp-comp
  • [22:51:37] <jwinnebeck> oh that script
  • [22:51:40] <jwinnebeck> but if it has bashisms
  • [22:51:46] <jwinnebeck> who cares it runs /bin/bash on the elisp-comp
  • [22:51:51] <jwinnebeck> I think
  • [22:51:58] <jwinnebeck> I think it's because emacs is symlinked to jove
  • [22:52:57] <jwinnebeck> it runs this: $EMACS -batch -q -l script -f batch-byte-compile *.el || exit $?
  • [22:53:03] <jwinnebeck> well $EMACS is emacs
  • [22:53:09] <jwinnebeck> and emacs is jove
  • [22:53:31] <jwinnebeck> but emacs isn't a dependency to compile, it can't be
  • [22:54:24] <jwinnebeck> I remove the emacs command it just says emacs not found
  • [22:54:26] <jwinnebeck> I better just install it
  • [22:55:20] <jwinnebeck> the operating system formally known as the text editor emacs...
  • [22:55:26] <CanyonMan> oh no
  • [22:55:30] <CanyonMan> haha
  • [22:55:33] <jwinnebeck> haha sorry chris
  • [22:55:37] <CanyonMan> ah it's ok
  • [22:55:38] <muriani> woglinde: bad news
  • [22:55:42] <jwinnebeck> hey it works now!
  • [22:55:43] <muriani> fails on beagle too.
  • [22:55:45] <jwinnebeck> now I can go home!
  • [22:55:50] <woglinde> jwinnebeck yeah
  • [22:55:56] <woglinde> muriani shit
  • [22:56:00] <jwinnebeck> woglinde: I don't think there was any bashism there just jove -> emacs
  • [22:56:09] <CanyonMan> you realize next time I go to do something and it opens up emacs you're going to hear about it :-)
  • [22:56:09] <woglinde> muriani write to oe-core ml
  • [22:56:15] <muriani> will do.
  • [22:56:17] <jwinnebeck> so blame debian for having /usr/bin/emacs point to jove when emacs is not installed but jove is
  • [22:56:29] <jwinnebeck> CanyonMan: then you can uninstall it :)
  • [22:56:37] <jwinnebeck> Ok I'm going home hopefully this builds

  • [22:58:47] <jwinnebeck> can't believe one needs emacs to compile
  • [22:58:51] <jwinnebeck> also, I hate automake
  • [22:58:54] <jwinnebeck> and make
  • [22:59:07] <jwinnebeck> I switched one project to CMAke years ago I love that when I have to work with C
  • [22:59:32] <woglinde> cmake sucks too
  • [22:59:41] <mru> make is wonderful
  • [22:59:45] <mru> cmakes sucks
  • [22:59:51] <woglinde> gm mru
  • [23:00:00] <jwinnebeck> haha

  • [23:00:24] <mru> my condolences
  • [23:00:28] <jwinnebeck> haha
  • [23:00:40] <jwinnebeck> I was wondering when I could get a response to that one :)
  • [23:00:49] <jwinnebeck> I thought I was going to be booted just for mentioning it
  • [23:01:06] <jwinnebeck> When the VM works it's very fast
  • [23:01:10] <jwinnebeck> so I will see about shark...
  • [23:01:12] <jsabeaudry> jwinnebeck: I tried building openjdk-6 and I get a failure on readline-native in the install operation
  • [23:01:32] <jwinnebeck> jsabeaudry: well I'll see how far I get
  • [23:01:39] <jwinnebeck> jsabeaudry: do you think I'll get that too?
  • [23:01:54] <woglinde> jsabeaudry ask muriani he hits it too
  • [23:02:03] <jwinnebeck> OK well
  • [23:02:05] <jwinnebeck> we'll see :(
  • [23:02:45] <jwinnebeck> sorry but I gotta go, I'll pop in later or Monday if nothing else 1300-0100 GMT
