ephloduron last question how do I add systemd to my final image00:02
*** tlab <tlab!~tlab@> has joined #yocto00:02
billrIn your conf/local.conf file, add: DISTRO_FEATURES_append = " systemd" and VIRTUAL-RUNTIME_init_manager = "systemd"00:04
billr(as two separate lines)00:04
billrIf you already have a DISTRO_FEATURES_append entry, then just add systemd to the list.00:05
ephlodurok ..btw I'm building an image for raspberry pi3 that does not make a difference00:05
billrshouldn't matter what your target is00:06
ephlodurdo I need DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"00:07
billrif you want both systemd init and sysv init. If you want only systemd init, I don't think you need the backfill entry. (Not an expert on that one.)00:08
ephlodurhow can I import openssl-dev whithout enabling dev-pkgs in EXTRA_IMAGE_FEATURES00:09
*** slips <slips!> has joined #yocto00:09
billrtry adding it to IMAGE_INSTALL_append in local.conf?00:11
ephlodurok thanks that the way IMAGE_INSTALL_append ?="openssl-dev"00:12

*** Aethenelle <Aethenelle!~Aethenell@> has joined #yocto00:13
billrYes, but put a space between opening " and 'openssl-dev'00:13
billrand I think you probably want just = and not ?= in this case.00:14
ephlodurok thanks I will try that now00:14
ephlodurit does not seem to like the MACHINE ??= "raspberry2"00:15
billrDo you actually have a "raspberry2" machine definition?00:16
ephlodurok the problem was I need to add MACHINE ??= raspberrypi200:17
billrand change the ?? to a single ?00:17
ephloduroh ok ..00:17
*** Aethenelle <Aethenelle!~Aethenell@> has quit IRC00:17
ephlodurcan I remove PACKAGECONFIG_append_pn-qemu-native = " sdl"00:18
billrok. ?? or ? may work depending on how your local.conf file is written. Looks like you got it, though.00:18
ephlodurfor an raspberry00:18
billrI don't think it will matter, as it should apply if you're not using a qemu target00:19
billrshould -> shouldn't00:19
ephlodurok thank.. now I building with an see what happen00:20

LetoThe2ndso did that work before? did you check that the branches (e.g. poky revisions and the fsl layers) match up?08:44
*** ftonello <ftonello!> has quit IRC08:45
xkonniLetoThe2nd: i'm using fsl layers. and i didnt build a sdcard image before. actually i just want something i can e.g. dd to the sdcard, tell uboot to run it, apt-get install packages and keep them when rebooting08:46
xkonnicurrently using an u-boot rootfs image. but its loaded in the ram and modifications do not persist08:47
LetoThe2ndxkonni: "i just want" is usually not helpful in debugging stuff ;-)08:47
xkonniLetoThe2nd: yes right. what i meant is: if there are alternatives to 'sdcard' that match my goals, i would consider using one of those08:48
LetoThe2ndxkonni: so take a step back. did you follow the fsl instructions on how to use and configure their layers? did a vanilla rebuild of their getting started guide succeed?08:48
xkonnithe u-boot image works perfectly08:48
xkonniso i just added 'sdcard' to the image_fstypes, rebuild, ^^ that error08:48
xkonnithe whole build is based on fsl layers08:49
LetoThe2ndbut is that the setup as described by them, or something you came up with yourself? does it carry any modifications?08:49
xkonnibesides the sdcard its pretty close to what they describe08:50
LetoThe2ndyou're evading my questions.08:50
xkonniadded some packages, vim, ... and deb package management08:50
xkonninot on purpose, let me try again08:50
LetoThe2ndstart over with a clean slate. find out when it breaks.08:50
xkonnimhhm... and a working build is not a 'clean slate'?08:51
LetoThe2ndand really make sure that all the included layer revisions match up08:51
LetoThe2nda working build is not a clean slate.08:51
xkonniok, so i take a minimal fsl image, build it, add 'sdcard' and build it again?08:51
LetoThe2ndbecause a working build still might carry modifications that just didn't show their effects yes.08:51
LetoThe2ndexactly. my advice is to get the initial, minimal setup that you were provided, and add absolutely nothing. build it, then add the sdcard fstype, and build again.08:52
xkonnii thought the problem would be something simple. like exceeding rootfs-size, missing some dependency08:52
LetoThe2ndif that already breaks, you know that you have to look in your upstream. if it works, you have to look in your modification.08:53
LetoThe2ndit also might be that the BSP just doesn't support the sdcard image.08:53
LetoThe2ndwhich its documentation should tell08:53
xkonnithats an option, yes... will check the other fsl-image configs08:54
*** willnewton <willnewton!~will@unaffiliated/willnewton> has joined #yocto08:55
xkonnithough the error tell me its something stupid: Exception: TypeError: cannot concatenate 'str' and 'NoneType' objects08:56
xkonnie.g. missing "" in a config08:56
LetoThe2nd... which *might* come from the sdcard setting triggering some function, but the layer not providing sufficient configuration data for your board.08:56
xkonnipossible... ;)08:57
LetoThe2ndtaking a first look at suggests that the sdcard fstype only makes sense for imx and mxs socs, by the way08:57
*** clopez <clopez!> has quit IRC09:03
LetoThe2ndby the way, if its only about persistency during development, you could also resort to a nfs root file system. but in any case, the process of making your device self-bootable and offering persistent memory should be provided by its documentation, as its highly board implementation specific.09:04
xkonnifound the actual issue... IMAGE_CMD is None for sdcard...09:05
xkonniand thats most likely, as you said, due to missing options for my platform09:05
LetoThe2nda.k.a. the layers you have do not support the sdcard image for your platform.09:05
xkonniright, thats what i wanted to say09:06
LetoThe2ndso see my last post before that conclusion :-)09:06
xkonniyes i just wanted to support your statement09:06
*** belen <belen!~Adium@> has joined #yocto09:06
LetoThe2ndnah, i meant the "by the way..." line :-)09:07
xkonninfs might work, but then i dont always have a network. having persistent data on the sdcard would be my favorite option09:08
LetoThe2ndthen its RTFM time :-)09:08
xkonninot necessarily with that sdcard image, there are certainly other options09:08
xkonniright, the docs are rare on that one though09:09
xkonniso instead of ls1021a + topic i ended up with yocto + topic09:09
*** clopez <clopez!> has joined #yocto09:09

skfaxWhen bitbaking a package X some other package Y fails. However when doing "bitbake -g X" and grepping the resulting dot file, there are no packages depending on Y. Why is Y included in the build?13:14
aurelerburton, can't find anything where was it discussed?13:22

*** LocutusOfBorg <LocutusOfBorg!~Gianfranc@ubuntu/member/locutusofborg> has left #yocto22:04
paulgbluelightning, I'm not sure if this has been done before, but I was entertaining the idea of identifying "hot" pkgs and ensuring they got preferential treatment in download, unpack, configure etc.22:05
paulgi.e. on a per step basis.22:05
*** Biliogadafr <Biliogadafr!> has quit IRC22:05
paulgthere is no rush to unpack gnome-icon-themes if we've not unpacked for building perl-native yet.  :)22:08
paulgthe odd time I've looked at a build and seen 5 or more pkgs all in do_package / do_rpm ; that is probably more of an I/O bottleneck than unpacking tho....22:11
kergothpaulg: i think bitbake already does its best to do that22:12
paulg...not sure how one would avoid that.22:12
kergothbottlenecks are built as early as possible in the task sorting22:12
kergothin the scheduler class22:13
paulgGood.  Then I can scratch that idea off my "should look into that someday" list.  :)22:13
kergothwe've expeirmented with adding weighting based on resource type / availability, i.e. no more than N unpack/patch, etc, but i'm not sure that sort of thing ever went anywhere22:13
kergothrichard's likely experimented with scheduling optimizations more recently than i, though22:13

paulgI wonder if the unpack would get a speed-up of pre-reading the entire pkg instead of interspersing the reads with writes...22:27
paulgI did something similar to that for gnu diff some many years ago.22:28
kergothI wonder how the performance is when doing builds on a tmpfs, I think someone was playing with that22:28
paulgI've done that on other build systtems but not oe/yocto/bitbake22:29
paulgthe difference wasn't super huge IIRC.22:29
*** lexano <lexano!> has quit IRC22:29
paulgthe "rm -rf" once done was however much improved.  :-)22:30
kergothmost useful script i have when doing yocto builds: bgrm. just nohup/disown's backgrounded rm -rf, after first renaming/moving it, so you can immediately start the next build rather than twiddling your thumbs waiting on the rm -rf tmp22:32
paulgya, I do sth similar ; "mv tmp deletmelater ; (sleep 12h ; rm -rf deletemelater) & "22:33
paulgif I'm still working in 12h then my life already sucks.22:33
paulgand less i/o contention assuming I don't need the space ASAP.22:34
paulggenerally speaking I try and push everything off a cliff as least often as possible.22:35
paulgbut it still happens too often.  :-/22:35
kergothsadly my remote build vms lack the space to delay the removal very far out :) especially when doing world builds. that's a great idea when you hvae the space, though22:35
paulgheh, looking at that old thread, I was testing on what was then a low end machine.  Whopping 32MB RAM.22:36
paulgyou'd not even stop to pick up a gfx card or router out of the trash with that amt of RAM now.  :)22:36
paulgGood times.22:39
JEEBreminds me of being quite happy in 1998 or 1999 because of getting a whopping 64 megabytes of EDO RAM :)22:41
