| fberg | hello guys, I'm compiling a library using a cutom recipe. During the do_package() I get this error: No GNU_HASH in the elf binary | 08:41 |
| fberg | I've add the following: do_compile(){ | 08:42 |
| fberg | oe_runmake LDFLAGS=--hash-style=gnu | 08:42 |
| fberg | } | 08:42 |
| fberg | but can't get rid of it | 08:42 |
| *** open-nandra_ <open-nandra_!~marek@81.89.61.168.host.vnet.sk> has joined #yocto | 08:44 | |
| neverpanic | make sure your library accepts LDFLAGS from the envrionment, then this should already work correctly without overriding do_compile() | 08:50 |
| neverpanic | Usually, using a well-established build system is the easiest way to achieve this. | 08:51 |

| fberg | neverpanic, solved thanks. Added TARGET_CC_ARCH += "${LDFLAGS}" | 09:04 |
| nayfe | loulou2 its due to kernel-module-split.bbclass, it removes empty folders | 09:09 |
| *** open-nandra_ <open-nandra_!~marek@81.89.61.168.host.vnet.sk> has quit IRC | 09:17 | |
| loulou2 | @nayfe ok we can simply add blacklist.conf deployement in do_install_append(), that's should do the trick no ? | 09:27 |

| loulou2 | @nayfe no update possible we have to keep 2.1.2, do you think KERNEL_MODULE_AUTOLOAD is broken in old Yocto version ? | 09:39 |

| rburton | fberg: native is the native recipe which provides binaries you can run at build time | 12:29 |
| rburton | such as glib-gettextize | 12:29 |
| *** marka <marka!~masselst@128.224.252.2> has joined #yocto | 12:30 | |

| loulou2 | @zazar just to be sure, you system is running on a persistent storage ? | 14:01 |
| zarzar | loulou2: yes it seems to only keep about 40 commands, HISTSIZE was not set, could that be the issue? | 14:04 |

| fberg | from openembedded I see that g-ir-scanner recipe is available from meta-gir. By the way it's pretty obsolete | 14:05 |
| fberg | a newer recipes by the way seems to compile g-ir-scanner-wrapper and it is gobject-introspection | 14:05 |

| loulou2 | @zazar maybe, according to the doc -> So for an infinite history list, make: HISTSIZE=(some number less than 0) | 14:07 |
| loulou2 | @zazar you can try export HISTSIZE=50 HISTFILESIZE=100 and try to save 50 cmds | 14:08 |

| *** Son_Goku <Son_Goku!~King_InuY@fedora/ngompa> has joined #yocto | 18:27 | |
| seebs | I'm staring at the thing, it turns out that I probably have to change the pseudo IPC structure to allow passing more than one dev/inode. | 18:31 |
| seebs | You actually *can't* do this safely/reliably without both names *and* both dev/ino pairs. | 18:31 |
| seebs | My concern is mostly that I don't think renameat2() should be present in libc and yet returning ENOTSUP. I think. | 18:31 |

| seebs | Huh. | 18:43 |
| seebs | Okay, fair enough, if glibc's not actually exposing it, we can probably avoid doing the thing yet. | 18:43 |
| seebs | Hmm. | 18:45 |
| seebs | So I have a man page for renameat2() on my system, which is why I assumed it was an actual function I could call. Maybe I should check this out more. | 18:45 |
| seebs | ... oh, right. kernel's documenting syscalls, glibc doesn't always provide them. Eww. | 18:47 |

| rburton | seebs: last time i fell for that it took me a few hours to discover that lots of projects were copy/pasting the same code from a manpage for a function which glibc never exposed and had a mistake in anyway, so even if they did add that wrapper it wouldn't work | 19:01 |

| AbleBacon | so, yocto creates linux images, right? like if i were to install windows, do the updates, remove a bunch of crap, and then install it on a bunch of computers, yocto is like a linux version of that? | 19:03 |
| rburton | erm, sort of? | 19:03 |
| AbleBacon | i'm just sort of trying to understand this conceptually because the guides just sort of dive right in | 19:04 |
| rburton | its a tool to build a custom linux-based operating system | 19:04 |
| AbleBacon | so, i'm trying to create a linux image for this embedded device we have, so why am i installing ubuntu onto a virtual machine and doing a bunch of stuff on it first in order to accomplish that? | 19:05 |
| rburton | no idea, you tell me | 19:05 |
| rburton | because the yocto tools don't work in windows? | 19:05 |
| AbleBacon | ok, so i'm configuring this ubuntu environment right now on this virtual machine--when does that turn into configuring the environment that i want on the embedded device? | 19:06 |
| fray | never | 19:06 |
| AbleBacon | i.e. i'm not sure what stuff is working towards getting yocto working, vs getting the finished image configured | 19:07 |
| fray | The Yocto Project 'build system', is a tool that runs on a Linux OS of your choice.. (which is ubuntu based on your description) | 19:07 |
| fray | from there you would configure a new -custom- Linux distribution that is YOUR embedded Linux distribution. | 19:07 |
| fray | You build it, and then get something out of it that can be deployed into your custom environment | 19:07 |
| AbleBacon | so my ubuntu machine is going to download a bunch of packages and things, but not for it--for the custom environment? | 19:08 |
| hastake | hello, if i feel like changing the init system to something else, how to make the link /sbin/init to somewhere else? if i do it in FILES_${PN} i have an error about someone else owning the link | 19:08 |
| fray | The Yocto Project build system requires a Linux based operating system to run on.. but it is purely a 'tool'. Ubuntu is only used as an OS to run the tool.. | 19:08 |
| fray | The Yocto Project tooling, running on your Ubuntu OS will download what it needs to compile that applications, that you configured, to create an image to run on your configured target. | 19:08 |
| fray | hastake, usually you would do this by defining a different initscript 'system'. I beleive currently sysvinit and systemd are defined.. you could define your own.. | 19:09 |
| AbleBacon | how come people don't just emulate the target hardware, install linux on it, get the stuff they need, and then save that as an image instead? | 19:09 |
| fray | Do you have an emulator for all available hardware? If so I'd like it.. baring that, we do build and use QEMU for some things.. but we're limited to the hardware (and CPUs) that qemu is capable of emulating.. | 19:10 |
| smurray | plus that's slow | 19:10 |
| AbleBacon | well, what if i have the hardware itself? | 19:10 |
| rburton | AbleBacon: the point is yocto is building the linux *you want*. not what ubuntu is, or redhat. | 19:10 |
| fray | There are severe limitations to the emulation on various IA, ARM, and Power platforms. (I think MIPS is fairly well emulated, unless you end up with a variant like the Cavium Octeon) | 19:10 |
| fray | AbleBacon, with some exceptions, USUALLY your host system is much faster at compiling then the target hardware.. | 19:10 |
| rburton | AbleBacon: if you have the hardware yourself and eg ubuntu is provided for it and it does what you want already then feel free to use ubuntu | 19:11 |
| fray | so everything is cross compiled. | 19:11 |
| AbleBacon | i wouldn't even know how to install linux on this ARM processor in the first place. but yocto takes care of that--right? | 19:11 |
| rburton | well, arm is comedy because none of them boot the same | 19:11 |
| rburton | which is kind of why you can't just get "ubuntu for arm" | 19:12 |
| fray | If your host system is not already faster -- or you don't want to cross compile -- or as rburton said, you have an existing OS to run on that.. you don't have to do this..... BUT there is another penalty.. reproducibility. The Yocto Project can repduce the same image using the same configuration over and over.. in a way that you can PROVE the sources you have are being used.. this is VERY important from a commercial perspective.. | 19:12 |
| *** armpit <armpit!~armpit@50-233-148-156-static.hfc.comcastbusiness.net> has joined #yocto | 19:12 | |
| fray | Ya, YP will be able to build the kernel and OS for a known board.. but most likely the install process (for most 32-bit ARM) is so custom, you will have manual steps to deploy it.. the BSP/machine layer usually includes instructions on how to deploy) | 19:12 |
| AbleBacon | so if i want to share my linux image with others, i save a small recipe file and send it to them and they can compile it themselves? | 19:13 |
| rburton | AbleBacon: yeah. or just share the image. | 19:13 |
| fray | You would share custom (code) content via layers.. configuration either via layers or simply 'here use this configuration', etc.. | 19:13 |
| rburton | but absolutely, the layers+image recipe is all they'll need to reproduce what you built. | 19:13 |
| fray | (You can of course share the binary, but again -- in a commercial setting that isn't a good idea for lawyers and such.. they want proof the source you said you used, you used.. so they know what the licensing agreements are) | 19:14 |
| rburton | again, useful in commericial environments where you want to do an update two years after shipping something. | 19:14 |
| AbleBacon | but they'd have to go in and do some fiddling to get everything set up, even if i told them what layers and recipes to use, right? | 19:14 |
| fray | No, if they use exactly the same layers and configuration as you do -- there is nothing further to 'setup'. | 19:14 |
| fray | Remember the Yocto Project builder is a tool that runs on your host.. | 19:14 |
| fray | and the host system must be a Linux based host.. (with a few other requirements) | 19:14 |
| AbleBacon | how would i send them the layers and configuration? is there like a makefile sort of thing? | 19:15 |
| fray | it just happens to be that a lot of people do this on Ubuntu.. but that isn't required.. it can be CentOS, Arch, RHEL, SuSe, even some Yocto Project based systems | 19:15 |
| fray | in your project directory you will have a conf subdirectory.. That is your configuration. | 19:15 |
| fray | the layers referred to by the configuration are almost always git repositories. Use whatever method you wish to share your git repositories (an current commit) with others | 19:15 |
| fray | (the build log always starts with a list of layers and the commit they are on for tracking purposes.. | 19:16 |
| AbleBacon | so the conf directory is everything... assuming another user has checked out the same version of yocto, if i send them my conf directory, their resultant image will be an exact match of mine? | 19:16 |
| fray | yes | 19:16 |
| AbleBacon | so why not have a single file that contains all of the information about the build? like how a makefile might work | 19:16 |
| AbleBacon | i feel like i could get going with an XML sort of deal a lot faster | 19:17 |
| fray | bitbake (the utility you are running) is roughly an equivalent to 'make'.. but way way more extensible and (for the purposes of this build) better able to handle the demands of the system. | 19:17 |
| *** yourfate <yourfate!~yourfate@unaffiliated/yourfate> has joined #yocto | 19:17 | |
| fray | There are various (not YP) programs that can take YAML, XML, or others and generate the .conf files.. | 19:17 |
| fray | but the .conf format ont he Yocto Project is fixed and has a history.. | 19:18 |
| rburton | AbleBacon: probab;ly easiest if you just try a build | 19:18 |
| AbleBacon | so if i want to have, say, GCC 6.10 on my system, i need a... layer for that? | 19:18 |
| fray | there is a learning curve.. | 19:18 |
| fray | the 'meta' layer (a.k.a. oe-core) contains the basics for the core system.. meta-yocto contains various stock distribution configurations.. and meta-yocto-bsps contains various sample BSPs.. | 19:18 |
| fray | there are additional layers you can download (see layers.openembedded.org) | 19:19 |
| fray | As far as GCC, if you want to use GCC.. then you would most likely use the one from oe-core (included) | 19:19 |
| rburton | AbleBacon: you generally get the gcc that comes with the version of yocto you use. changing compiler is *not easy* | 19:19 |
| AbleBacon | oh excellent! i was wondering how to find the specific thing i need for this chip | 19:19 |
| fray | if you wanted to use some alternative version, you may have to implement something yourself.. this is definitely an 'advanced' operation | 19:19 |
| fray | search for your COTs dev system on layers.openembedded.org.. be sure to swithc the 'branch' to whatever branch of the YP you are using.. | 19:20 |
| fray | (Rocko is the last released version).. this changes every 6 months... | 19:20 |
| fray | if you truely have something 'new', then you will need to learn how to do multiple parts of the system -- but usually you can start with one of the QEMU bsps, and then adjust from there | 19:20 |
| AbleBacon | so the ones on that site are the open source ones? i'm seeing my manufacturer has their own BSP, but it's not listed on that site | 19:22 |
| fray | then your manufacturer has not published it to the index -- or they only support it for a different version. You may have to look at older releases. | 19:24 |
| fray | Rocko is current, but it's not unusual to support latest (master) or ancient versions (way past support) | 19:24 |
| Crofton|work | using a several year old version is a bad idea. No good source for updates | 19:24 |
| fray | httpstr://wiki.yoctoproject.org/wiki/Releases | 19:24 |
| fray | ... https://wiki.yoctoproject.org/wiki/Releases ... that gives you an idea of how old something is by the code name (branch name) | 19:25 |

| AbleBacon | so if they're mentioning the "krogoth" release in this documentation, i should not try to use rocky? | 19:25 |
| fray | anything older then 1 year should not be used.. and even something as old as one year should be carefully considered.. | 19:25 |
| fray | Krogoth is 2.1, April 2016 | 19:25 |
| fray | the Yocto Project does community (best effort) support for about 1 year.. so that is no longer supported after April 2017 | 19:26 |
| AbleBacon | but if i try to use a newer version, it definitely won't be compatible? | 19:26 |
| fray | (if you have a commercial provider, they certainly can and do extend support longer then 1 year.. but the community generally does not) | 19:26 |
| fray | most likely it will not be directly compatible -- which means you will have to port the kernel and/or other pieces (say an SDK).. | 19:26 |
| fray | if it's a common board, others may have already done it.. if it's not a common board.. beat up the board maker | 19:26 |
| AbleBacon | yeah it's like an ancient board i'm pretty sure | 19:27 |
| AbleBacon | pretty cool, tho. size of a coaster. technology these days! | 19:27 |
| *** Son_Goku <Son_Goku!~King_InuY@fedora/ngompa> has quit IRC | 19:28 | |
| fray | You can use krogoth, and it will probably work.. but it will be harder to ask general questions when you have a problem.. | 19:28 |
| fray | if this is just a hobbiest system.. that may be good enough for you (especially if you are just learning) | 19:28 |
| AbleBacon | eh, not exactly--it's a class 3 medical device :-/ | 19:29 |
| fray | for that, I'd definitely recommend either beating up the board vendor for something newer -- or finding a commercial provider.. | 19:29 |
| fray | (commercial providers often have 3, 5, 10, or even 15 year support... plus can advise some additional options when working in the medical or similar spaces) | 19:30 |
| fray | (i.e. from a system licensing perspective, medical devices often can't allow an end user to modify them -- but the GPLv3 license may require that.. which often means don't use GPLv3 software..) | 19:30 |
| fray | these are things that the Yocto Project can help you do, that other systems (like Ubuntu) can not.. | 19:31 |
| fray | (nothing wrong with Ubuntu, it's just not built for that environment) | 19:31 |
| AbleBacon | right--i wasn't thinking i could use it on here, but i was confused about why i needed it on a virtual machine. makes sense now though | 19:31 |
| fray | Commercial OSVs, as well as consultants and such often have a lot of experience in these areas to help you get started or support you long-term | 19:31 |
| fray | (I work for an OSV, as do others on this channel -- as well as semi makers, ISVs and consultants...) | 19:32 |

| fray | OSV -- Operating System Vendor.. ISV - Independent Software Vendor (generally applications, sometimes more) | 19:33 |
| fray | Semi's (the guys who make the CPUs).. board vendors (you already know that).. etc | 19:33 |
| AbleBacon | ah | 19:33 |
| AbleBacon | yeah, we got vended some of this qt framework stuff from one of those | 19:34 |
| fray | OSV - Wind River (who I work for), MontaVista, Mentor Graphics, Enea and many others.. | 19:34 |
| fray | I'd consider QT software to usually be an ISV.. | 19:34 |
| AbleBacon | right | 19:34 |
| AbleBacon | i should probably just turn off my brain and follow these instructions and see where it gets me | 19:37 |
