LetoThe2ndgrokreality: this is appearing when doing what? you have checked that you are not mixing branches? on which recipe?08:24
grokrealityits for the beagleboard xM (meta-ti) using daisy branch.08:25
LetoThe2nderps08:25
LetoThe2ndthat is about as outdated as possible08:26
grokrealitydoing bitbake core-image-minimal08:26
LetoThe2ndso besides the advice to check everything is equivalently on daisy... well... maybe upgrade? ;-)08:26
grokrealitywhich is daisy branch...which do you think would be a better branch. plz help.08:26
grokrealityi mean is daily branch outdated?08:27
LetoThe2ndgrokreality: https://wiki.yoctoproject.org/wiki/Releases08:27
LetoThe2ndgrokreality: daisy is 3.5 years old08:27
grokrealitythanks for the advice...i was just following instructions from a n old blog...08:28
LetoThe2ndplus, beagle-xm is alsmost equivalently outdated and unsupported08:28
grokrealityoh. :(08:28
grokrealityjust wanted to start with yocto and have this hardware around...08:28
LetoThe2ndyou can easily start with openembedded without hardware, we have reasonably good qemu support08:29

nayfeHi everyone, do you know if we can override / with overlayfs if / is already mounted ? something like mount -t overlay ofs / -o lowerdir=/,upperdir=/data/overlay/,workdir=/data/work/08:43

rburton'meta-selftest: fix upstream version checks for devtool test recipes'12:56

kanavinupstream check uri is so that the recipe doesn't report that the version is unknown which improves the overall statistics12:57

sveinseI'm currently experimenting with a Yocto build for an Intel FPGA SoC. I see that they setup a meta-linaro-toolchain. Why would they? Why is there a Linaro toolchain and how is it different from the one in stock Yocto/OE?13:53

Tamis_I would like to ask what is the biggest advantage to use native recipe to build a tool instead of using the same tool from.14:26
Tamis_Do you have a link to read online about that?14:26
Tamis_from host*14:26
kanavinsveinse: LTS can be purchased from commercial yocto vendors; it's simply beyond the community's capacity14:26
rburtonsveinse: you'll have to ask the fpga bsp people the linaro question14:27
kanavinTamis_: in short, then we would know exactly what we're getting when we use that tool (or library etc.). Fighting with a zoo of desktop distributions is a major pain.14:27
kanavinTamis_: the downside is that building the tool takes time, maintaining the recipe and its dependencies takes effort14:28
rburtonTamis_: example: we build subversion-native because subversion had a few serious changes in behaviour where we can't cater for both at the same time.  build our own, we know what we're getting.14:30
Tamis_kanavin: I see. So the biggest advantage is that get the exact version and behaviour we want. Instead of fighting with what the current distro provides14:32
Tamis_But with all those new tools like VM's docker's etc. Wouldn't make above consideration a little bit obsolete?14:34
rburtononly if we start shipping a VM for people to build inside14:34
rburtonwhich so far, we're not14:34
Tamis_I see. Ok thanks.14:35
ramcqthe flatpak sdk can actually run yocto inside flatpak when building14:35

sveinsekanavin, rburton: thanks14:36
sveinseallthou i've never really understood what linaro adds to the table (and not just for yocto-things) ...but yes, not a Yocto question14:38
ramcqupstream work on ARM support across the Linux ecosystem - for example upstreaming and maintaining good ARM support in gcc, linux, a u-boot that actually supports multiple boards, ...14:39
kanavinit will be a sad day when VM becomes a requirement for development14:39

neverpanicAnd those indirection layers often hide real issues, too.14:42
sveinseI can vouch for that: Before we changed our product to Yocto, we used Ubuntu (they were the first to have good support for armhf back in the days). We need to use docker and maintain a container with the host tools that matches the (old) version of the target system. It's a pain to maintain.14:43
*** Nilesh_ <Nilesh_!uid116340@gateway/web/irccloud.com/x-fcyxrttghahzbadx> has joined #yocto14:44
Tamis_From what I see here and there, devops and build systems are using heavily VM's and dockers and those stuff. So I guess that a lot of things are moving towards there.14:46
*** toscalix <toscalix!~toscalix@167.98.27.226> has joined #yocto14:47
neverpanicAbsolutely agree, but even those VMs and containers aren't stuck at fixed versions, so you either need to continuously test with newer containers (and then adapt your code to support both versions or drop support for the older version), or you're stuck with an old container (which is even worse)14:48
kanavinnot to mention that VMs and containers have their own bugs, too14:49
kanavinqemu can be very frustrating for us, and we only use it to do (simple) testing - the image boots, ssh works, etc.14:50
*** Tamis_ is now known as Tamis14:50
TamisThanks for all these inputs. I am really new to all these devops things so I want to know about all those considerations.14:53
TamisI am changing our development process to use yocto for all the image creation and those questions pop up all the time14:54
TamisI spent quite some time to make some java apps to build using ant-native and mvn so I really wandering if those time was well spend to make the yocto tools to work instead of just install those tools to the host machine14:55
neverpanicBtw, full disclosure, we're using a container for Yocto builds, too. It just takes another variable out of the equation when bugs occur. But we're also not very interested in finding every obscure bug that would make binutils or some other fundamental component fail to build.14:56
sveinseThe distro feature 'multiarch', does it affect non-intel architectures? From what I can see from code when grepping, it seems not, but does it have impact on host tools?14:59

sveinseI wish bitbake would have a way to redefine a ?= value. The use case is that a machine conf includes tune-cortexa9.inc which sets DEFAULTTUNE ?=, and that the machine conf also would like to that, but with a different default value.15:47

nayfecan't you use something like DEFAULTTUNE_<machine> override ?16:03
nrossisveinse: you normally set the ?= value in the machine.conf before the include of the tune16:03
sveinsesveinse: lol :D, yes16:04
nrossisveinse: not sure your problem then? ?= behaves that why on purpose ;)16:05
sveinsenrossi: That would make more sense. But grepping a little bit around, it seems the DEFAULTTUNE_<machine> is more common?16:05
*** toscalix_ <toscalix_!~toscalix@82-70-136-246.dsl.in-addr.zen.co.uk> has joined #yocto16:05
nrossisveinse: i've never needed to set it with an override since that would break the nesting of DEFAULTTUNE16:06
nrossie.g. if someone wants to include the machine.conf to create a derivative machine, then the override would not work16:07
sveinsenrossi: nesting?16:07
sveinsenrossi: yes, I see, but this is the case from a 3rd party machine layer. And it's certainly not the first time I've seen this16:08
sveinseThe fix is that I need to fork this layer and do the appropriate reordering of the statements so that is defaults correctly16:09
nrossisveinse: ideally yes16:10
nrossisveinse: which/whose bsp layer is it out of query?16:10

sveinsenrossi: perhaps. no idea. I've forked the repo and will fix it, because I don't like having to rely on large edits in local.conf16:19
nrossisveinse: you can always do it from a distro config, like how meta-angstrom rewrites DEFAULTTUNE for arm targets: https://github.com/Angstrom-distribution/meta-angstrom/blob/12a9410dff0806bf2b57b42920d2431f592c38d5/conf/distro/include/arm-defaults.inc#L2816:20

sveinsenrossi: I suppose it depends on how one interprets "distro". For some uses, like a complete image for a speicifc product or HW, then a distro can be machine specific. While if distro is a generic collection of functionlity, then I suppose machine shouldn't be a part of that equation.16:28
