07:19.05melchiori've a user "User" on my system and i'm using busybox, is possible and what to do for the system system automatically log into this user account at startup ?
07:30.45Jacmetkos_tom: hi
07:31.06kos_tomJacmet: hello! Do you have some news about the wiki ?
07:31.18Jacmetkos_tom: wiki? ehh, no
07:31.33Jacmetkos_tom: did we decide to get one installed?
07:32.00kos_tomJacmet: ah, I thought we agreed to try, but it seems the agreement wasn't so clear :-)
07:32.04Jacmetkos_tom: I'll need to check with the osuosl guys about it, the VM is quite limited ressource wise
07:32.26Jacmetkos_tom: what wiki would you prefer?
07:33.02kos_tomJacmet: the MediaWiki thing seems to be the most widely used one.
07:33.02Jacmetkos_tom: there's afaik no php or similar on the VM
07:33.17kos_tomJacmet: ah, a Wiki without PHP is hardly doable.
07:33.44Jacmetkos_tom: we've been using moinmoin in the past
07:33.48Jacmetwhich is python based
07:35.02kos_tomis it a nice wiki ?
07:35.15Jacmetkos_tom: but ok, python or php probably doesn't matter much
07:35.22Jacmetkos_tom: I find it ok
07:35.45kos_tomI think people in general are more familiar with MediaWiki, which is very popular/widely used.
07:36.35Jacmetkos_tom: maybe the best solution is to install the wiki somewhere else while testing and point wiki.buildroot.(net|org) at it
07:38.05Jacmetkos_tom: does mediawiki require a mysql/postgresql database?
07:38.49kos_tomJacmet: yes, MySQL. If you don't want a database, there's also dokuwiki which is OK.
07:39.24kos_tomJacmet: yes, installation in wiki.buildroot.org sounds a good idea to me. We'll see what we manage to do with it, and if it works, migrate it to buildroot.org.
07:40.19Jacmetkos_tom: ok, sounds good
07:46.08Jacmetkos_tom: I had some comments on your ext-toolchain 02/10 regarding your sysroot handling - Have you had a chance to look at that?
07:47.30kos_tomJacmet: I have seen your comment, but I didn't had the time to look at that, unfortunately.
07:48.00Jacmetkos_tom: ok - no problem, I just think you and Yann agreed I should merge your series before his
07:48.13Jacmetkos_tom: did you write a proposal for ELCE?
07:48.31kos_tomJacmet: nope, in the end I decided that I didn't had anything interesting enough to present.
07:50.21Jacmetkos_tom: ok, that's a pity - It sounded interesting to me
07:50.32Jacmetkos_tom: are you involved with the ubifs work from CELF?
07:55.44CapnKernelHello.  My buildroot (2010.05) sometimes fails in the X install with this: cannot create regular file `/data/home/mjd/src/buildroot/output/staging/usr/include/xorg/bstorestr.h': File exists
07:56.10JacmetCapnKernel: only sometimes?
07:56.10CapnKernelThis is in "xserver_xorg-server 1.7.5 'Installing to staging directory'"
07:56.20CapnKernelOnly sometimes.  Maybe it's a -j race condition.
07:56.28CapnKernelIf I re-run make, it goes away.
07:56.43CapnKernel(perhaps, don't quote me on that)
07:57.30JacmetCapnKernel: hmm, it shouldn't be, we use make -j1 for xserver install
07:57.58JacmetCapnKernel: that was a fix shortly before 2010.05
07:58.09CapnKernelMy JLEVEL is 6, and I don't separately supply any -j.  
07:58.21JacmetCapnKernel: good, you shouldn't
07:58.39CapnKernelLooking, yes, it seems it's a race: http://fpaste.org/HwyE/
07:58.55JacmetCapnKernel: if you scroll up you should see make -j1 DESTDIR=....output/staging install
07:59.32*** join/#uclibc BlindMan (~othmar@h081217021188.dyn.cm.kabsi.at)
08:00.04CapnKernelUnfortunately it seems to have -j6: http://pastebin.org/369705
08:00.26JacmetCapnKernel: argh, I see the problem
08:00.31CapnKernelI kicked off this build with "make -C buildroot"
08:00.39JacmetCapnKernel: I fat-fingered it
08:00.53CapnKernelIt happens :-)
08:01.12CapnKernelSlipped a patch?
08:01.30JacmetCapnKernel: if you change xserver_xorg-server.mk to have XSERVER_XORG_SERVER_MAKE = $(MAKE1) instead of XSERVER_XORG_XSERVER_MAKE (notice the extra X) it should work
08:03.40CIA-4603jacmet 07master * r09b36fc0644b 10buildroot/ (2 files in 2 dirs): xserver_xorg-server: fix _MAKE typo
08:03.46kos_tomJacmet: no, I'm not involved in the UBIFS work from CELF.
08:04.02kos_tomJacmet: currently, I'm working almost full-time for TI, to do some OMAP Power Management stuff in the kernel.
08:04.44Jacmetkos_tom: ok
08:05.18CapnKernelJacmet: Thank you thank you!
08:05.35JacmetCapnKernel: you're welcome, thanks for reporting it
08:05.43CapnKernelYou guys amaze me.
08:07.03JacmetCapnKernel: that's just the kind of guys we are ;)
08:07.18CapnKernelROFLs
08:15.35CapnKernelOdd: It seems there's a difference between "make -C buildroot" and "cd buildroot; make".
08:18.54JacmetCapnKernel: hmm, there shouldn't be according to the make documentation
08:19.22CapnKernelI agree.
08:19.33JacmetCapnKernel: what difference do you see?
08:19.44CapnKernelI'll try to isolate it now.
08:20.50JacmetCapnKernel: thanks
08:22.37CapnKernelOk, I have reproduced it: http://pastebin.org/369748
08:23.41CapnKernelBasically, I do two runs.  Before both runs, I zap output/build/xdriver_xf86-video-geode-2.11.8 (but I don't think it's caused by this package; rather, it just gives make, and pkg_config, something to do).  The difference between the runs is "make -C buildroot" vs "cd buildroot; make".
08:25.19CapnKernelLine 241 is the start of the second build.
08:25.46JacmetCapnKernel: and /home is a symlink to /data/home?
08:26.03CapnKernelI think so.
08:26.10CapnKernelLines 261 and 262 look important.
08:26.24CapnKernelYes re your symlink question.
08:27.05kos_tomit complains because the value of CC, CFLAGS, etc. has changed.
08:27.25JacmetCapnKernel: it seems like make resolves the path on make -C
08:27.32JacmetCapnKernel: E.G. line 5
08:28.14JacmetCapnKernel: you're in /home/mjd/src and do a make -C buildroot, which makes make cd /data/home/mjd/src/buildroot
08:28.36JacmetCapnKernel: which invalidates the paths in the configure cache
08:28.47JacmetCapnKernel: so this is basically a make issue
08:29.10CapnKernelYes.  We thought there shouldn't be a difference, but apparently there is.
08:29.24JacmetCapnKernel: that only triggers if you use the configure cache, build partly with -C and without and your buildroot tree path contains symlinks
08:29.43JacmetCapnKernel: I'm afraid we cannot do much about that
08:30.09CapnKernelI agree.  Not worth the time if it takes all three to reproduce (although configure cache is now the default)
08:30.44JacmetCapnKernel: yes, because of the build time speedup
08:31.21Jacmetkos_tom: when are you planning on going/leaving from Cambridge? Mon->Sat?
08:31.43CapnKernelNoted.  Thanks!
08:32.11kos_tomJacmet: yes.
08:34.15Jacmetkos_tom: ok, arranged hotel already?
08:34.52kos_tomJacmet: no, not yet, so if you find some good stuff, let me know.
08:35.00kos_tomI suppose you're going by train, right ?
08:35.30Jacmetkos_tom: I don't know yet - I got my boss to pay, which means it has to go though the corporate booking stuff
08:35.41Jacmetkos_tom: but I'll see what they come up with
08:38.38CIA-4603vda.linux 07master * rcd0f6b0c939e 10busybox/ (archival/rpm2cpio.c include/unarchive.h libbb/read_printf.c): consolidate xz format comment. no code changes
08:39.42kos_tomJacmet: hum, ok. I also go through the corporate booking stuff, but it's actually me :-)
08:41.54Jacmetkos_tom: yeah, the joys of working at a "big" company
08:42.37Jacmetkos_tom: you have to fill in a request, and it needs to get approved (by several people) - Once approved the travel agency will propose several options and you need to decide within a limited amount of hours
08:48.42CapnKernelUsually the travel agent suggests options, the cheapest of which is still far more expensive than if you organised it yourself.  Such is the magic of corporate travel agencies...
09:13.17kos_tomCapnKernel: I thought so, but I recently had to use the TI travel agent, and it found a plane ticket that was exactly the cheapest price you could find by yourself, and then even had discount on hotels you couldn't find.
09:17.07CapnKernelMy times have changed!  (I used to work for HP)

12:54.43Jacmetkos_tom: well, you're also a bit further away ;)
12:54.57Jacmetkos_tom: stansted is afaik the nearest
12:55.35kos_tomyeah, but they are no flights between Toulouse and Stansted.
12:55.54Jacmetkos_tom: ahh
12:57.16kos_tomso I'll either go to Heathrow or Gatwick and take the train, or I'll go to Carcasonne by train (1h from Toulouse), from which Ryanair has cheap flights to Stansted.
12:59.14dj-deathare you talking about elce ?
12:59.43kos_tomyep. Do you plan to come ?
12:59.51kos_tomif so, can you stay on Friday for the Buildroot Developer Day ?
12:59.52dj-deathyes
13:00.06dj-deathyes again

13:02.39kos_tomJacmet: it depends on the airport. Seems that from Gatwick or Heathrow, it's more ~2h.
13:02.48kos_tomdj-death: ok, glad to know you're coming.
13:03.04Jacmetkos_tom: ahh, yes
13:04.54dj-deathbeware, sometimes the train from paris -> london spends up to 17h in the tunnel ;)

17:05.18kos_tomJacmet: sorry :-)
17:05.36Jacmetkos_tom: git grep or ctags
17:05.49Jacmetkos_tom: I agree that it isn't very nice
17:05.59Jacmetkos_tom: (the download override)
17:06.14kos_tomJacmet: yeah, I'm grepping a lot too, but when you've got a totally new pile of code where things are cross-referenced in quite crazy ways, it becomes a bit limited.
17:06.37Jacmetkos_tom: true
17:06.38kos_tomJacmet: yeah, I think I'll try to implement something better (that at least I find better, we'll see if you like it)
17:08.00Jacmetkos_tom: please do - this was just a quick fix for the obvious brokenness of the tremor package
17:08.36kos_tomJacmet: in addition, you're not only overriding the download step, but also the extraction step.
17:09.02kos_tomI'm not even sure how it can work with the .stamp_extracted step
17:09.58Jacmetkos_tom: no, I'm only overriding the download step
17:10.08Jacmetkos_tom: the extract step is just like normal
17:10.34kos_tomJacmet: aah, your download step rebuilds a tarball
17:10.45kos_tomaah, yes, it's a bit ugly :)
17:12.07Jacmetkos_tom: yes, it creates a tarball, just like the tremor package has always done
17:12.30Jacmetkos_tom: I think that's pretty ok, as it then behaves quite like the normal tarballs
17:13.12ChipsaruHi. I need help. I have arm machine based on uClibc (DLink DNS-323) and I want to compile uClibc 0.9.31 for that device with locale support. When I'm trying to compile it on this device with locale support - uClibc wants locale utility from glibc (which is not installed and I can't compile it). What should I do? I'm not a hardcore linuxman.
17:14.43kos_tomJacmet: yes, it works.
