09:07.04ao2hi, I've got this 3.2 kernel for armv5te (machine a780 from meta-handheld) which fails to boot when compiled with the current meta-toolchain built with OE (gcc-4.8.2), it boots fine when compiled with an older toolchain from OE (gcc-4.5.x), this is my bblayers.conf https://gitorious.org/openezx/oe-ezx-build/source/9239cede81c496504f5a5050bc73463389c98671:build/conf/bblayers.conf Is it OK for meta-toolchain?
09:08.15ao2Where should I report this kind of issues?

09:27.48ant_workao2: we were about obsoleting that family of devices
09:27.59ant_workgood that you jump in
09:30.10ant_worknow, I can say that other armv5te devices do boot with the standard-built toolchain
09:30.49ant_worknote, I don't include the toolchain-layer
09:31.03koencame across an a780 while tidying up this weekend
09:31.22ant_workheh
09:31.25ao2ant_work, hi, I can try without toolchain-layer
09:31.54ao2hi koen how are you doing?
09:32.41koenao2: pretty good, and you?
09:33.57ant_workao2: try straight 3.14
09:34.09ao2koen, not too bad either, thanks
09:34.50ao2ant_work, do you mean a 3.14 kernel?
09:34.58ant_workyes, can we remove that openezx-kernel_git ?
09:35.47ant_workput your defconfig in linux-yocto_3.14
09:36.10ao2ezx devices are still bound to a 3.2 kernel with a lot of non mainline stuff
09:36.17ant_workargh
09:37.06ao2but if you want to remove this old stuff from mainline OE we can put them in a dedicated layer
09:37.30ant_workwe are collecting all in meta-handheld possibly under the same linux-yocto recipe
09:37.51ant_workkoen: btw it would be great if you'd give a try to hx4700
09:38.16koenI'll have some time thursday, remind me then
09:38.23koenrelease week this week
09:38.34koenand a day shorter due to thursday being a holiday

12:34.50mago_if I set PREFERRED_PROVIDER_x = "y" and PREFERRED_VERSION_y = "1.0", it should include v1.0 of "y" in my image if it depends on x, right?
12:35.36mago_Well, I'm getting this warning: "NOTE: consider defining a PREFERRED_PROVIDER entry to match u-boot" (where u-boot is my "x" in the above example)

15:41.38stefan___I'm trying to use the meta-mingw layer to build a mingw-based SDK. Some of the projects I'm trying to include appear to be pulling in nativesdk-eglibc, which seems entirely wrong. Any idea how I should address that ?

15:49.02nerdboywinding up the clue stick for #wandboard...
15:49.53nerdboystefan___: not sure...  do you have a preferred_provider set for libc?
15:50.19stefan___nerdboy: I don't even know what that is.
15:50.46nerdboytasslehoff: maybe a deploy task with install -d ?
15:51.42stefan___nerdboy: conceptually I would expect the meta-mingw layer to provide its own C runtime, so eglibc shouldn't be used at all (on the host machine, that is).)
15:52.11stefan___but I don't know how that is expressed in terms of poky vocabulary.
15:52.44nerdboygrep your .conf files for PREFERRED_PROVIDER_virtual/libc
15:53.35nerdboyactually, bitbake -e grep foo will show you what it is in your build env
15:55.57stefan___the value is eglibc
15:56.29nerdboythat would be incorrect for what you want...
15:57.52stefan___what does this variable express ? Is that the host C runtime ? (and what would be the name of the target runtime ?)
15:58.31nerdboynothing to do with "host" at least not outside bitbake env
15:58.50nerdboyit's the libc used for your toolchain and runtime
15:59.14stefan___which runtime ? host or target ?
15:59.23nerdboyis still not clear on where the proper place is
15:59.38nerdboytarget runtime and and sdk/toolchain
16:00.40nerdboytry adding PREFERRED_PROVIDER_virtual/libc = "foo" in yout local.conf
16:00.45stefan___Right, but that should be (e)glibc. I'm trying to build an SDK for mingw, so I need a mingw-based runtime for the host-side, and a normal (e)glibc-based runtime for the target.
16:00.58nerdboywhere foo == one of the other libc options
16:01.20stefan___sorry, I'm not sure what the options are.
16:01.38nerdboywhat does mingw need for libc?
16:02.03stefan___I don't know. I think it is downloading a pre-built mingw package from sf.net
16:02.15nerdboyit's been a long time since i played with mingw but iirc that was based on a "normal" gnu toolchain?
16:02.55nerdboywell, if that's true then maybe eglibc is correct
16:03.14nerdboyrunning out of a**-hairs
16:03.55stefan___yeah, I think it is just doing a canadian cross compilation of gcc. Well, it did manage to compile nativesdk-eglibc, but it failed to install it.
16:05.01stefan___ponders writing a mail, unless RP is around on irc to help
16:24.33stefan___nerdboy: the meta-mingw layer contains a "nativesdk-mingw-w64-runtime" package that contains 'PROVIDES += "virtual/nativesdk-libc"'
16:25.12stefan___that sounds to me like it is building the host-side C runtime for the mingw layer, no ?
16:26.07nerdboyyup
16:26.44stefan___so why nativesdk-eglibc, then ? It's not referenced in that .bb file, it must be pulled in from somewhere else.
16:28.03nerdboyif that package got built, the info file should have deps
16:28.22nerdboythere's a dot file dep graph command as well
16:29.37nerdboymaybe there's a missing virtual you need in your config?
16:31.09stefan___I once tried to build a dependency graph. The image was *huge*, so I stopped trying to open it (I killed gimp after it almost brought my machine to its knees during startup.)
16:31.53stefan___and I never got to the point where a package depending on eglibc was built, given that eglibc itself failed to install (due to some path issues)
16:32.16stefan___So, I still have no idea what is dragging in eglibc as nativesdk C runtime.

18:20.16khemnativesdk-libiconv nativesdk-libintl
18:20.49khemunless your recipes provide them it will pull in nativesdk-eglibc
18:21.18khemand usually we do depend on our own version of libc to be running on sdk host machine
18:21.28*** join/#oe tasslehoff (~Tasslehof@145.79-161-31.customer.lyse.net)
18:21.56stefan___khem: OK. So if it is expected that eglibc is built for mingw, we need to figure out why it fails to install. Some paths are wrong...
18:21.58khemsince we depend on rpath manipulations to run cross compilers and other native tools in SDK
18:22.16khemstefan___: I would suggest to go that route yes
18:23.24tasslehoffmaybe slightly OT, but do anyone know why I can't also have an entry in fstab that shows me /dev/mmcblk0p2 in /media/mmcblk0p2 as well as in / (rootfs)?
18:23.39tasslehoffa bit too much also and as well there :)
18:24.33khemtasslehoff: you mean you want it to be automounted ?
18:24.48khemyou can write udev rules for that
18:27.30khemthere already is mount script in udev IIRC
18:27.33*** join/#oe JokerDoom (~JokerDoom@24-196-46-114.dhcp.fdul.wi.charter.com)
18:27.38khemwhich should work in most cases
18:27.46tasslehoffkhem: on my beagleboard I had /media/mmcblk0p[1-4] in /etc/fstab, and they were all mounted. on my wandboard all of them show up in the mountpoints except the one that contains the rootfs
18:27.59tasslehoffand is therefore already mounted on /
18:28.09tasslehofftrying to find the x-factor
18:29.00khemits mounted as / already so whats the need to get it automounted under /media
18:31.08tasslehoffkhem: convenient for my upgrade scripts. they extract the new rootfs to /media/mmcblk0p2 or 3 based on where the running rootfs is.
18:31.29tasslehoffNot very important, but I'm curious what has changed
18:31.47*** part/#oe JokerDoom (~JokerDoom@24-196-46-114.dhcp.fdul.wi.charter.com)
18:31.48tasslehoffbut, if this is OT I'll try some detective work of my own.
18:33.06khemyou wont be overwriting mounted rootfs I assume so if it does not exist in /media then its mounted as /
18:33.52khemtasslehoff: btw. is it same version of OE that mounts it on beagle
18:33.57khemand not on wandboard ?
18:34.12tasslehoffkhem: nay. 1.4 on beagle, 1.6 on yocto.
18:34.26khemoh well
18:35.04tasslehoffI guess :)

18:35.44khemtasslehoff: there were few changes done on automounting /
18:35.51tasslehoffkhem: but! you gave me another good idea. to automount the partitions instead of keeping them in fstab
18:35.53tasslehoffok
18:36.10khemand 1.4 to 1.6 is a bigger jump so there could be more causing it
18:36.19khembut I would suggest to look into that area
