| *** AustrianCurrent <AustrianCurrent!~AustrianC@c-73-133-243-111.hsd1.md.comcast.net> has quit IRC (Quit: Client closed) | 00:03 | |
| AustrianCurrent4 | Also new to IRC chats, I apologize :( | 00:03 |
| moto-timo | AustrianCurrent: bitbake builds intermediate packages (ipk, deb, rpm) and uses those to stitch together the final image (in the case of rpm with dnf) | 00:03 |
| moto-timo | AustrianCurrent4: you can set up a "package feed" to expose your rpms as a dnf repo to install packages on the target... it's not trivial but can be done. You can also use e.g. devtool deploy target to send a particular update to the target board. Some folks prefer to use TFTP or NFS during development time to make this all easier/faster. | 00:05 |
| AustrianCurrent4 | moto-timo: Interesting, can these RPMs be 2nd party (to Yocto) and RPMs I build via CPack or rpm or do they have to be create via bitbake? | 00:07 |
| AustrianCurrent4 | So the package feed seems to be a dnf repo derived from Yocto build artifacts. However, can you plop a custom built or 3rd party RPM in it and expect Yocto to pick it up? | 00:08 |
| moto-timo | AustrianCurrent4: I call those third party RPMS... they _might_ work... but not likely. Very brittle. The reason is that you are not in control of gcc, glibc, libraries, etc. that were used to make those 3rd party rpms. Yocto Project/Open Embedded bootstraps itself from a minimal set of host tools and then owns everything beyond that. Everything is consistent. | 00:09 |
| AustrianCurrent4 | moto-timo: Even if a nightly-built SDK is being used to build the RPMs via CPack? | 00:10 |
| moto-timo | AustrianCurrent4: and rpm is not universal. It has a pedigree. Many many factors go into whether it will be compatible with your architecture, specific board, specific version of libraries/applications. It is a road to madness. | 00:10 |
| moto-timo | AustrianCurrent4: if you are using a Yocto built SDK (or eSDK "extensible SDK") then you will have better luck. I don't personally have any experience with CPack so I cannot claim any knowledge. I have experience with Fedora's modularity, Flatpack and snaps. All of them are a road to pure unabashed insanity. You will only go down a path of seeming compatibility to find that the bridge behind you is on fire and you have no where to go. | 00:12 |
| moto-timo | AustrianCurrent4: the Yocto Way is to build everything from source. For a reason. | 00:12 |
| *** AustrianCurrent <AustrianCurrent!~AustrianC@2601:152:4d00:84b0:7912:542f:b4aa:6017> has joined #yocto | 00:15 | |
| AustrianCurrent | moto-time: Interesting. So it's highly encouraged to use source builds. That's fair. I've seen layers like this https://github.com/conan-io/meta-conan that do similar things to what I'm trying to attempt but like you're saying it's a dark road | 00:15 |
| moto-timo | AustrianCurrent: all the stars must be aligned for that to work. Everything must be ABI/API compatible. Once some binary only change happens you are hosed. Dead in the water with no rope. | 00:17 |
| moto-timo | AustrianCurrent: swtich to a new SoC or a new board? hosed. | 00:17 |
| moto-timo | AustrianCurrent: meanwhile, with properly curated Yocto Project layers... a switch to a new SoC could be as simple as MACHINE="foo" -> MACHINE="bar". Done. (Not always that simple) | 00:18 |

| AustrianCurrent | moto-timo: Okay, so to not have to touch a bitbake file every time I patch a library, I should still make a bitbake file but use the AUTOREV and make sure I version my so's | 00:19 |
| moto-timo | AustrianCurrent: when I first started on this path, I had 9 SKUs to worry about. I knew there was no way that I could do that with e.g. Buildroot and stay sane. | 00:19 |
| moto-timo | AustrianCurrent: I do not recommend AUTOREV except for early development. Just get your git foo in shape and keep the SRCREV updated (or the sha256sum of the tarball or whatever). | 00:20 |
| moto-timo | AustrianCurrent: AUTOREV forces a fetch for parsing. It slows everything to a crawl and if there is ANY glitch in networking you are completely hosed. Done. No way out. | 00:20 |
| * moto-timo has strong opinions on certain things. | 00:21 | |
| AustrianCurrent | Ah haha, gotcha. So I guess that goes back to my fundamental problem, I want to be able to push out minor and patch bumps that maintain ABI compatibility without having to edit a bitbake file. | 00:22 |
| moto-timo | AustrianCurrent: you can use for instance "devtool upgrade" to make the workflow simpler to update recipes... it's not perfect but it works well in some use cases | 00:23 |
| moto-timo | AustrianCurrent: why? what is the aversion to editing the bitbake file? It is just part of your "source". Yeah, it's metadata. Just keep your source trees and your metadata in sync. It's not that much effort IMHO. | 00:24 |
| * moto-timo on a bit of a high horse right now... so take this with a grain of salt | 00:24 | |
| AustrianCurrent | Yeah just takes up some extra bandwidth I guess. | 00:25 |
| moto-timo | worklfow: edit library source, push commit, change SRCREV in bb, build, deploy to target | 00:25 |
| moto-timo | depending on your team size you can use "devtool modify" to edit the source library... likely that isn't going to fit the bill, but it might. | 00:26 |
| moto-timo | the extensible SDK was designed to allow a hybrid... you have an SDK but you also have _some_ of the bitbake tooling. Not perfect. | 00:27 |
| AustrianCurrent | Interesting | 00:28 |
| moto-timo | TBH, I spend _much_ less bandwidth on the metadata updates than I do on patching/upgrading components to newer versions or new functionality. | 00:28 |
| moto-timo | out of date, but https://www.youtube.com/watch?v=d3xanDJuXRA | 00:29 |
| moto-timo | and also (me) https://www.youtube.com/watch?v=CiD7rB35CRE | 00:29 |
| AustrianCurrent | I guess I have a team full of people who like to use shared libraries, so it I guess to them it feels like extra effort to support a recipe for every library and have to increment every patch. However, I think that's because it's early development. I do have a dependency with a fairly complex build process that I am sort of concerned about creating | 00:33 |
| AustrianCurrent | a recipe with because it needs npm and java-runtime. It's easy to build and package myself. But I do see meta-nodejs and meta-java are things. | 00:33 |
| AustrianCurrent | I will look further into the devtool workflow though. I think this will solve a lot of my problems developing these recipes. | 00:34 |
| moto-timo | I look at layers as Lego(TM) building blocks... pick and choose what you need to make the CoolThing | 00:35 |
| moto-timo | in the long run, you are much better off re-using upstream anything that is well maintained than home grown... without question. | 00:35 |
| moto-timo | and the corollary is it is in your best interest to contribute to upstream | 00:36 |
| moto-timo | technical debt will be a noose around your neck that drags you to the poor house. | 00:36 |
| moto-timo | if those shared libraries are autotools, meson, cmake... etc. well behaved build systems, devtool add and devtool upgrade will likely JustWork(TM) out of the box. As long as you don't have crutches of things like PLATFORM=$(shell uname -m) or similar... those things are not cross-compile friendly. Everything in OE/YP is cross-compiled... even x86_64 on x86_64 for x86_64 | 00:41 |
| AustrianCurrent | Basically use proper install rules? | 00:42 |
| AustrianCurrent | for cmake I gues | 00:42 |
| smurray | AustrianCurrent: developers wanting to build shared libs on their dev machines and then piecing them together in some ad hoc build process is a recipe for disaster down the road in production. | 00:43 |
| moto-timo | code like it is 1976... it will work. Code like a cool block chain bro and it will break. | 00:43 |
| moto-timo | smurray: rescues me from blathering on and on and on and on | 00:44 |
| * moto-timo steps away | 00:44 | |
| AustrianCurrent | Yep, everyone wants to use RPMs because it's how we managed dependencies before; however, this is the first time on a true embedded system so it's quite the change | 00:44 |
| smurray | AustrianCurrent: Chris Simmonds has given some talks on the pros/cons of using OE/Yocto versus Debian, maybe look for those, as he addresses some of what I suspect you're interested in | 00:46 |
| AustrianCurrent | So I assume to give a customer something that you build from source, to do it the yocto way we would have to deliver a layer of binaries. I will watch those talks on YT, thanks smurray | 00:48 |
| smurray | AustrianCurrent: it depends on what your deliverable is, if you build a h/w product with upgradeable firmware, then you build images and give them to people somehow for upgrades, and Yocto can also be used to build source drops for meeting license requirements for the FOSS parts | 00:50 |
| AustrianCurrent | smurray: Thanks, yeah that and potentially a SDK they can use to build their own layer on ours. | 00:52 |
| smurray | AustrianCurrent: yes, building a SDK that can build binaries to run on your target is also something you can do pretty easily | 00:53 |
| moto-timo | AustrianCurrent: you can also use an OTA solution like foundries.io, mender, updatehub, rauc, swupdate | 00:53 |
| * moto-timo really steps away | 00:54 | |
| AustrianCurrent | Thanks moto-timo and smurray. I will take this back to my team and try to persuade them off our possible road to doom | 00:55 |
| smurray | AustrianCurrent: good luck! | 00:56 |
| AustrianCurrent | Thanks! | 00:57 |

| kayterina[m] | Hello. I get error "omitting directory" from do_install(). Is it because I try to install -m a folder structure? It is a .tar.gz that I want to copy over to the target, I untar it in do_compile(). | 09:47 |
| hmw[m] | is there a build container for dunfell ? | 09:47 |
| LetoThe2nd | kayterina[m]: the canonical way is using cp: https://stackoverflow.com/questions/39980145/how-to-install-recursively-my-directories-and-files-in-bitbake-recipe/47084404#47084404 | 09:48 |
| LetoThe2nd | hmw[m]: depends on what you call "build container". there is crops, there is pyrex, there is kas - all are container solutions that can build a dunfell release. there is my personal one at theyoctojester/devcontainer-local-yoep, but it might need tuning for you. so what do you need in particular? | 09:49 |
| LetoThe2nd | is there anything out in the wild for generating encrypted rootfs? or is it all internal-homebrew stuff at the moment? | 09:56 |

| Schiller | in the YPAutouilder it is necessary to have a User with root privileges. What is the recommended way for this task? Simply changing the UID in /etc/passwd to 0 would make my User root. | 10:33 |
| rburton | why do you need a root user? | 10:46 |
| RP | Schiller: you definitely do not need a root user | 10:48 |
| Schiller | it is stated here https://git.yoctoproject.org/yocto-autobuilder2/tree/README-Guide | 10:49 |
| Schiller | and without i can't access /home/pokybuild3/git/... in step (Clobber build dir) | 10:49 |
| RP | Schiller: that guide says you setup the pokybuild user from the root user, it doesn't say pokybuild has to be root | 10:50 |
| RP | Schiller: /home/pokybuild3/git should be owned by pokybuild so that should be ok | 10:51 |
| Schiller | ok ill readd the user as root and will check again. | 10:51 |

| selff | hello everyone, im running an image with openvpn in rpi4. i enabled "AUTO_SYSTEM_ENABLE" in "openvpn_2.4.9.bb". i also put the existing client_vpn_test.conf file in /etc/openvpn. however, the service cannot run the config. when "openvpn@client.service" is run, it prints the following error: job for openvpn@client.service failed because the control | 11:10 |

| selff | See "systemctl status openvpn@client.service" and "journalctl -xe" for details. | 11:10 |

| ndec | RP: only when you look at the 'dev' (4.0) version.. if you pick another one, the 4.0.999 is gone! | 11:13 |
| RP | ndec: right I think it is because dev (4.0) *is* 4.0.999 | 11:14 |
| RP | ndec: I think a " and ourbranch != devbranch" addition to the config should solve that | 11:16 |
| RP | I've pushed something to hopefully sort that | 11:18 |
| qschulz | RP: why do we add ourseries to activereleaes line 202? | 11:23 |
| qschulz | RP: also I think we shouldn't have kirkstone in release_series since it's not out yet | 11:24 |
| qschulz | same for lts_releases | 11:24 |
| qschulz | or bitbake_mapping | 11:25 |
| Schiller | RP:I did setup the hole thing again as root (added user cloned repos etc.). As what User should i start the Autobuilder manually. Either way (pokybuild3 or root) i'll run in some path or permission problems. | 11:40 |
| rburton | you only need root to create the new user | 11:42 |
| rburton | everything else should be done as pokybuild | 11:42 |
| rburton | well, the static tap nodes creation is a root task, but that should be done at boot. | 11:42 |
| Schiller | when i run want to start the janitor as pokybuild3 i already run into permission issues | 11:43 |
| Schiller | and when i sudo the janitor command i will run into permission issues during buildtime in step 1. (Clobber build dir) | 11:44 |
| rburton | hard to help with just 'permission problems' | 11:44 |
| rburton | everything should be happening as pokybuild | 11:44 |
| rburton | that user owns the home directory, the build trees, and the source trees | 11:45 |
| selff | Can anyone help with openvpn? | 11:47 |
| Schiller | so to clarify i should be able to run the janitor as pokybuild3 without any root privileges after a correct setup. | 11:48 |
| Schiller | i changed some paths in the ab-janitor file and now i manage to start a build. | 12:13 |
| Schiller | in step 9 (Check run-config steps to use) i get the generated json file but no tasks other tasks are run. It just stops without creating a build. Any suggestions? | 12:14 |
| RP | Schiller: correct, janitor should be fine as pokybuild3 | 12:15 |
| RP | Schiller: I don't understand that since it should extend the steps needed as defined in the json file :( | 12:16 |
| RP | Schiller: I wonder if something changed in a more recent buildbot version? You could compare the version you're using for the controller with what we use on the autobuilder? | 12:16 |
| RP | qschulz: we add it there so that the current release series is displayed in the switcher ? | 12:17 |
| RP | qschulz: kirkstone needs to be in release_series since devbranch is set to kirkstone and we need to be able to resolve that | 12:18 |
| RP | qschulz: setting devbranch to honister would just mean there is no "dev" entry in switchers which would be worse | 12:19 |

| dacav | hello. | 15:09 |
| dacav | I'd like to verify some properties of the kernel that yocto builds, e.g. if a certain .c file is compiled or not. In order to do so, I'm trying to put some garbage in the file, and I would expect bitbake to fail. It does not fail... | 15:10 |
| dacav | The modification is done in the kernel-source directory that yocto checks out | 15:11 |
| qschulz | dacav: how do you build? | 15:11 |
| dacav | In this directory I can see, for example, that yocto applied the patches in the do_patch phase. | 15:11 |
| dacav | qschulz: I build via something like `bitbake my-linux` | 15:11 |
| dacav | (In short, the kernel seems to lack certain symbols, that should be there according to the defconfig) | 15:12 |
| qschulz | dacav: bitbake has no knowledge of modification in the sources | 15:12 |
| qschulz | dacav: use devtool modify my-linux if you want | 15:12 |
| dacav | I'm not modifying the recipe. I'd like to change the sources in flight, without pushing a commit to a branch | 15:13 |
| dacav | Basically I'd like to mess around without spending time to a proper patch | 15:13 |
| qschulz | dacav: that's exactly what i mean, you're modifying the sources and not the recipe, which is not watched by bitbake | 15:14 |
| qschulz | dacav: use devtool modify | 15:14 |
| dacav | When you say it has no knowledge of the modification in the sources, do you mean that it will not re-build it because it does not detect a change on the remote git repo, so it assumes no change has been done, so it will not invalidate the cached binary? | 15:14 |
| qschulz | yup | 15:14 |
| dacav | aha! | 15:14 |
| dacav | So is `devtool modify` going to put me in the sources? | 15:15 |
| * dacav tries | 15:15 | |
| qschulz | it's going to fetch+patch the sources in a specific workspace | 15:15 |
| qschulz | where you'll be able to modify stuff | 15:15 |
| qschulz | and then use bitbake like you would normally do | 15:15 |
| dacav | OK! Sounds good | 15:15 |
| dacav | thank you qschulz, precious as always | 15:15 |
| qschulz | bitbake has some mechanism to watch over devtool workspaces changes (see externalsrc.bbclass specifically if I'm not mistaken) | 15:16 |
| dacav | OK. So now I have the kernel sources in two places, I believe | 15:23 |
| dacav | will yocto only rely on the one in workspace/sources/? | 15:24 |

| rfs613 | dacav: yes. If you look at conf/bblayers.conf you will see that devtool has added the workspace/sources as a layer. (This caught me by surprise when I remove the workspace and bitbake started complaining...) | 15:35 |
| moto-timo | devtool creates a bbappend that points to workspace/sources until you “devtool finish” or “devtool reset” as I recall | 15:39 |

| MrSaturn | Alright, I may have come up with something... after running "savedefconfig" I copy it to the old _defconfig, git add, git commit, then run "devtool finish". The only issue remaining is that I have 4 other patches in the layer, and it sets the number of the latest patch as 0001 | 16:07 |
| qschulz | MrSaturn: the name of the patch does not matter to bitbake | 16:09 |

| dacav | rfs613: thanks. I wonder on what basis it will take the precedence... maybe (?) by the fact that the layer is listed in the last position? I'll experiment some later :) | 18:31 |
| rfs613 | dacav: layers have priorities, try "bitbake-layers show-layers" and note the number at the far right of each line. | 18:33 |

| jonmason | there is other stuff with hvc0 that needs to be figured out, but I can drop those patches | 20:24 |
| jonmason | essentially, without those being present, poky-tiny sprays errors on stdout forever as fast as it can | 20:25 |
| jonmason | err..with hvc0 being in the machine conf file, but not being present | 20:25 |
| RP | jonmason: I couldn't remember where we were at with them to be honest | 20:25 |
| jonmason | they worked, khem said there was unnecessary stuff in there, and I needed to pull it out. since I was waiting on the kernel configs to get it, I sat on it. But I did an update the other day and seems like they are in there now | 20:27 |
| RP | jonmason: ah, yes, think I had to pull the patches as the kernel bits weren't there yet | 20:27 |

| MrSaturn | Huh. I am looking at some freescale kernel recipes. It looks like it copies the defconfig into ${B}/.config and other layers just dump config fragments to the end of the config. Is this a normal pattern? It makes maintining patches to the config file painful. | 20:44 |
| abelloni | RP: jonmason thinks https://autobuilder.yoctoproject.org/typhoon/#/builders/103/builds/3818 is a bitbake server timeout, this was going to also be my first thought but I don't remember how we triaged the previous time we have seen that | 20:48 |

| RP | abelloni: hmm. Do we still have the logs? | 20:48 |
| abelloni | it was yesterday, so possibly | 20:49 |
| jonmason | it did seem to match what was in there for the others | 20:49 |
| RP | it doesn't look like the usual server timeout tome | 20:50 |
| abelloni | I have to grabe something to eat, can you check? | 20:51 |
| abelloni | (hte logs) | 20:51 |
| RP | abelloni: the logs are there I think | 20:51 |
| dacav | rfs613: thanks | 20:51 |
| RP | nothing useful :/ | 20:51 |
| jonmason | RP: any idea why systemtap tests would fail in master-next? I see nothing in the queued patches that is related, and I don't see any open bugs about it being a known issue | 20:56 |
| RP | jonmason: was that the centos7 one? | 21:00 |
| jonmason | yes | 21:00 |
| RP | jonmason: I didn't get a conclusive answer but I think the copying times were very high, around 290s in a 300s timeout | 21:00 |
| RP | so I thought it was IO load related | 21:01 |
| *** Minvera <Minvera!~Minvera@user/Minvera> has quit IRC (Remote host closed the connection) | 21:01 | |
| smurray | MrSaturn: I believe all the kernel recipes in meta-freescale are based on kernel-yocto.bbclass, so .cfg fragments should work with those | 21:01 |
| jonmason | RP: should I open a bug to track it or just mark it down to hw? | 21:02 |
| RP | jonmason: best ask abelloni what to do with that, whether there is an existing one | 21:02 |
| jonmason | abelloni: https://autobuilder.yoctoproject.org/typhoon/#/builders/79/builds/3325 is the offender | 21:03 |
| RP | abelloni, jonmason: I did dig a little into that timeout in the buildbot UI and it is odd. The bitbake-cookerdaemonlog says the build ran for 10 mins and the server exited | 21:03 |
| RP | We can get the timestamps of the step from https://autobuilder.yoctoproject.org/typhoon/api/v2/builders/103/builds/3818/steps/11 | 21:03 |
| MrSaturn | smurray: do you have any advice for working with fragments like that? I am used to using devtool + patches. It seems like there must be a workflow I am unfamiliar with here. | 21:04 |
| RP | which match the start time in the log, translating the epoch value | 21:04 |
| smurray | MrSaturn: take a look at https://docs.yoctoproject.org/kernel-dev/common.html#creating-configuration-fragments | 21:05 |
| MrSaturn | smurray: thanks! | 21:05 |

| *** steev_ <steev_!~steev@de1.hashbang.sh> has joined #yocto | 21:25 | |
| steev_ | hi, i am trying to setup a yocto build environment at my workplace. one thing we are struggling with is how to version our application recipes during the development cycle. could someone please point me to some common techniques which don't have us point our app.bb do git HEAD? we would like for each meta-foo commit to represent a known snapshot of application commits at that point | 21:27 |
| jsbronder | steev_: This still ends up pointing something at HEAD, but it might be helpful: | 21:30 |
| jsbronder | We have a virtual/app with two recipes that (R)PROVIDE it, app.bb and app-live.bb. | 21:30 |
| jsbronder | For nightlies, we build the app-live.bb recipes, which point at HEAD, for releases we build the app.bb recipes which point at an annotated tag. | 21:31 |
| jsbronder | The app-live.bb recipes also dump some `git describe` output in /etc so we can trace back. | 21:32 |
| jsbronder | </hand-waving> | 21:32 |
| jsbronder | There's also externalsrc (https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#ref-classes-externalsrc) but I came up with the above before I knew about its existence. | 21:33 |
| *** florian <florian!~florian@dynamic-093-132-070-235.93.132.pool.telefonica.de> has joined #yocto | 21:37 | |
| steev_ | jsbronder: thanks. so if you ever wanted to reproduce a build from last Wednesday, how would you do it? | 21:40 |
| JaMa | moto-timo: I no longer work on meta-ros, not sure if OSRF already moved the maintenance to someone else | 21:40 |
| moto-timo | JaMa: ok. I didn't know that. Thank you for the heads up. | 21:40 |
| moto-timo | FWIW I got galactic building on kirkstone... no idea how useful/functional it is | 21:41 |
| JaMa | moto-timo: https://discourse.ros.org/t/ros-2-tsc-meeting-january-20th-2022/23986/3 | 21:42 |
| jsbronder | steev_: With mild effort; you have the shas in /etc. Each app-live.bb recipe has something like: | 21:42 |
| jsbronder | APP_URI ?= "uri pointing to tip of master>" | 21:43 |
| jsbronder | SRC_URI = "${APP_URI}" | 21:43 |
| jsbronder | So, you can override APP_URI to point to whatever sha. | 21:43 |
| JaMa | moto-timo: it was working fine on oe master as of 2021-12-06 when I did the last update, at least the LAYERSERIES_COMPAT needs to be changed after that, but I haven't built anything with meta-ros in 2022 | 21:44 |
| jsbronder | That said, we archive the artifacts from each nightly for quite a while, so in reality I'd just go back and pull those. | 21:44 |
| moto-timo | JaMa: understood. I won't pester you about it anymore ;) | 21:44 |
| moto-timo | a few minor warnings about licensing changes and so on... plus a couple distutils3 changes... but anyway. I'll try to follow the community | 21:45 |
| JaMa | moto-timo: you can pester Rob Woolley of WindRiver or someone from Xilinx who was also interested in maintaining meta-ros .. | 21:45 |

| moto-timo | JaMa: well, I hope you are moving on to better things! 🍻 🏎️ | 21:50 |
| jsbronder | steev_: Honestly, if you care about reproducibility, you should be pulling from tags. | 21:50 |

| Guma | Hello Everyone. I am testing my first Yocto build on my board. After booting, I added the account manually for now. Later I can focus on integrating it into Yocto the build. The issue I am puzzled by is that when I log in to this account "adb shell" or "ssh" simple error "socket: Permission denied when I try to ping any server. Do I have to add a new user to some group? I can ping just fine as root. | 22:00 |
