Dec 21 05:58:08 <xtron> anyone recently worked on SELinux?
Dec 21 06:07:26 <grokreality> hi all
Dec 21 06:08:26 <grokreality> while building x-load in meta-ti I face ERROR: oe_runmake failed
Dec 21 06:09:00 <grokreality> arm-poky-linux-gnueabi-ld: cannot find -lgcc. Can somebody plz help me.
Dec 21 06:13:09 <grokreality> I'm using morty branch for meta-ti
Dec 21 06:13:33 <paulg> grokreality, you need to indicate what package in the build failed, by quoting more context of your error message.
Dec 21 06:16:38 <xtron> how to keep running the bitbake build after error,  I already use -k but it stops after broken patch, I want to see how many patches are broken
Dec 21 06:17:36 <paulg> not finding / linking against lib gcc has different meaning for a user space package vs. say a kernel build.
Dec 21 06:19:30 <paulg> xtron, you cant do that.  If patch B depends on A, and patch C depends on B, and patch D depends on C...
Dec 21 06:20:15 <paulg> If you throw out "A" then everything will seem like it is broken.
Dec 21 06:20:36 <xtron> paulg, you're right, but there should be some way to check that how many error are there, isn't
Dec 21 06:21:02 <grokreality> the package was x-load. the bootloader for omap3xxx.
Dec 21 06:21:46 <xtron> paulg, most of the patches are independent
Dec 21 06:27:48 <paulg> grokreality, that is good information.  A bootloader 99% of the times has to be static linked.  It has no idea of a file system or library or ldd concepts.  It needs to be a simple binary that the processor can execute out of reset, gradually enabling features like DDR controllers for memory, and then MMU so it can relocate.
Dec 21 06:29:18 <paulg> Such a thing can not expect to use a gcc library on a linux filesystem; it has no idea what linux is at that early stage.
Dec 21 06:30:39 <sledz> Anyone tried to cross-compile for MS Windows target with Yocto/OE?
Dec 21 06:37:08 <grokreality> hi paulg. can i send u the error msgs here.
Dec 21 06:37:18 <grokreality> or a file?

Dec 21 06:41:18 <paulg> grokreality, "bitbake -c devshell x-load"
Dec 21 06:42:11 <paulg> take your same cut and paste above and drop the "-lgcc" and run it.
Dec 21 06:43:25 <paulg> [hint: the directory of the build in temp has copies of "run" scripts that you can cut and paste from.]
Dec 21 06:44:18 <paulg> I don't know anything about your platform, but the -lgcc seems somewhat suspect.
Dec 21 06:47:33 <paulg> I worked on u-boot for PowerPC a lot of years ago, so you get to decide if it is best to ignore me or listen to me.  ;-)
Dec 21 06:47:59 <grokreality> hey paulg...why wud i ignore u... ;)
Dec 21 06:49:41 <grokreality> could u explain the drop -lgcc part?
Dec 21 06:49:51 <grokreality> from the Makefile?
Dec 21 06:50:16 <grokreality> I ran the -c devshell, could u tell me wht next?
Dec 21 06:56:00 <paulg> The "drop -lgcc part"...   you are asking to link into the lib gcc bundle of functions.  But a bootloader only needs to know how to configure the hardware and then serial port and/or display+keyboard
Dec 21 06:57:10 <paulg> it should not need complex libraries of functions, and worse == it (bootloader) does not know how to load on-demand shared libraries.
Dec 21 06:57:29 <grokreality> I ran the ./temp/run.do_compile script and face the same -lgcc not found issue.
Dec 21 06:57:36 <grokreality> in the devshell that is.
Dec 21 06:58:11 <paulg> did you actually *delete* the "-lgcc" part from that script?
Dec 21 06:59:43 <paulg> what I'm trying to say is, nothing in the bootloader should *need* that but if you put it on the link command line, then it has no choice but to tell you the files were not found.
Dec 21 07:01:56 <paulg> all that said, boot-loader code is tricky.  To bundle it with a bigger build just makes it more prone to failure.
Dec 21 07:02:03 <grokreality> no -lgcc does not exist in the script
Dec 21 07:02:10 <grokreality> in the LDFLAGS section.
Dec 21 07:07:40 <paulg> grokreality, the "devshell" puts you in an environment where you can cross-compile stuff for your target, including the bootloader.
Dec 21 07:08:06 <grokreality> but i do find libgcc.a in the -L path in BUILD_LDFLAGS variables?
Dec 21 07:08:59 <paulg> I still think this is a bug.  Bootloader stuff should not require that library.
Dec 21 07:09:30 <paulg> Bootloader code should be almost pure assembly for that particular processor.
Dec 21 07:10:35 <grokreality> ok. so to try where shud i purge the -lgcc from? the Makefile?
Dec 21 07:11:25 <grokreality> i found libgcc.a here:  ./tmp/work/beagleboard-poky-linux-gnueabi/x-load/1_1.5.1-r3/recipe-sysroot/usr/lib/arm-poky-linux-gnueabi/7.2.0/libgcc.a
Dec 21 07:16:17 <paulg> again I have to confess that I know *nothing* about booting the beagleboard.  But what I *do* know, is that boot loader binaries have been static linked for pragmatic reasons for a decade or so.
Dec 21 07:21:01 <grokreality> thanks paulg. :)

Dec 21 07:25:18 <devik> Hi :)
Dec 21 09:07:52 <nayfe> morning
Dec 21 09:18:08 <Tamis> morning
Dec 21 10:25:31 <yocti> New news from stackoverflow: Difference between layer and metadata in Yocto <https://stackoverflow.com/questions/47922619/difference-between-layer-and-metadata-in-yocto>

Dec 21 15:19:23 <RP> zeddii_home: how did the kernel testing play out?
Dec 21 15:41:08 <zeddii_home> my tests all passed. I was going to send that patch series out shortly.

Dec 21 16:22:36 <RP> zeddii_home: cool, if you send I can merge as I already tested it! :)
Dec 21 16:23:05 <RP> rburton: mut is looking rather sad :(
Dec 21 16:23:57 <RP> hmm, the above is another apic hang :/
Dec 21 16:25:08 <RP> rburton: ok if I merge the kernel patches to master?
Dec 21 16:25:19 <rburton> yeah
Dec 21 17:56:33 <BubuIIC> is there some machine specific folder where I can put files that can be referenced in SRC_URI?
Dec 21 17:58:50 <BubuIIC> i.e. referincing the same file from multiple recipes
Dec 21 18:16:54 <BubuIIC> for using the same devicetree for kernel and uboot build
Dec 21 18:49:10 <moto-timo> halstead: ping. looks like we want the nexus instance again... I forget the status
Dec 21 18:50:52 <moto-timo> halstead: also we will be needing to update the downloads.yp.org eclipse mirrors for neon.3 and oxygen.1 oxygen.2 versions
Dec 21 19:11:50 <ikkysleepy> Does anyone have an example on how to start an existing service automatically ? I want to enable the dnsmasq on on the build so when I flash the image it auto starts.
Dec 21 19:18:17 <nayfe> BubuIIC> you can use files/<machine> folder
Dec 21 19:18:45 <nayfe> <ikkysleepy : sysvinit or systemd ?
Dec 21 19:21:27 <ikkysleepy> Systemd
Dec 21 19:21:28 <nayfe> BubullC: example here: http://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#customizing-a-recipe-for-a-bsp
Dec 21 19:23:00 <ikkysleepy> So the service exist already but I need to enable it, I tried a symlink but it didn't work: ln -sf ${systemd_unitdir}/system/dnsmasq.service ${D}${sysconfdir}/system/multi-user.target.wants/dnsmasq.service
Dec 21 19:23:58 <nayfe> <ikkysleepy> it's because dnsmasq is in conflict with systemd resolved I think, let me check
Dec 21 19:26:34 <ikkysleepy> <nayfe> I have similar issue with starting hostapd , both services install fine but I can't figure out how to build the image with the service enabled. I have a bbappend scripts for both
Dec 21 19:27:16 <nayfe> ikkysleepy: I added After=systemd-resolved.service in dnsmasq-noresolvconf.service (with bbappend) because dnsmasq tried to start before resolved is running
Dec 21 19:28:13 <BubuIIC> nayfe: thank you. I will look into it tomorrow.
Dec 21 19:28:43 <nayfe> ikkysleepy maybe better to enable resolvconf in PACKAGECONFIG  not sure
Dec 21 19:30:00 <ikkysleepy> i'm just making a simple Access Point on RPI3 and I already have it working except for the build part. I guess the next solution I can think of is start up script to start dnsmasq and hostapd
Dec 21 19:32:52 <nayfe> ikkysleepy: it's all about dependency in systemd, maybe check systemctl status and journalctrl to see where the error comes
Dec 21 19:34:09 <ikkysleepy> is it true that the  dnsmasq and hostapd should have been enabled by default?
Dec 21 19:35:04 <nayfe> i think it is enabled, but somehow they fail to run when they are launched
Dec 21 19:36:04 <ikkysleepy> I can enabled them on first boot and it works but I want this to happen without me having to do it. I'll check the logs ...
Dec 21 19:56:00 <ikkysleepy> Reporting back, there is an issue with the dnsmasq starting up: Jan 01 00:00:06 raspberrypi3 dnsmasq[238]: dnsmasq: syntax check OK. Jan 01 00:00:06 raspberrypi3 dnsmasq[241]: dnsmasq: failed to create listening socket for 10.0.0.1: Cannot assign requested address Jan 01 00:00:06 raspberrypi3 systemd[1]: dnsmasq.service: Control process exited, code=exited status=2 Jan 01 00:00:06 raspberrypi3 systemd[1]: dnsmasq.service: Unit ente
Dec 21 19:58:18 <nayfe> did you try to add After=systemd-resolved.service ?
Dec 21 20:01:24 <ikkysleepy> I just add this line to the bbappend?   After =  "systemd-resolved.service"   ? If so, i am building / testing and will report back
Dec 21 20:03:33 <nayfe> <ikkysleepy nop in dnsmasq-noresolvconf.service file, under After=network.target
Dec 21 20:04:16 <ikkysleepy> oh you want me to modify the source code mmm...
Dec 21 20:05:38 <nayfe> you can override the file by add it with bbappend
Dec 21 20:29:51 <ikkysleepy> <nayfe> that seemed to work. =D
Dec 21 20:40:01 <nayfe> Nice
Dec 21 20:49:20 <kergoth> see also `recipetool appendfile`, which automates overriding files in recipes on target
Dec 21 21:03:19 <mrk377> Quick question:  I updated kernel options and created new rpms for my yocto distro with the same kernel version.  I installed the new RPMs and after reboot the /proc/config.gz is not showing the changes.  Is a boot loader changed required to recognize new kernel location?
Dec 21 21:57:55 <mrk377> Any yocto developers online?
Dec 21 21:58:09 <Son_Goku> NEVAHHHH :D
Dec 21 21:58:34 <Son_Goku> mrk377, in all seriousness, most of the Yocto folks are on vacation for the Christmas holidays
Dec 21 21:58:39 <mrk377> LOL.  I have a question about a updating a vmlinux image on my build root.
Dec 21 21:58:40 <Son_Goku> though some people are hanging around anyway
Dec 21 21:58:56 <Son_Goku> and I'm just an idiot that hangs out here because I can ;)
Dec 21 22:05:10 <rburton> mrk377: ask the question and you might get a reply
Dec 21 22:08:31 <mrk377> OK.  I have created new rpms for all the kernel-*.rpm files using a new defconfig recipe.  I remounted my read-only filesystem to read-write and installed the kernel-*.rpm files.
Dec 21 22:09:49 <mrk377> The /boot/bzImage-3.14.57-yocto-standard-custom is different, but the when I "zcat /proc/config.gz" the kernel options are not changed?  Did the kernel update actually work, since it is the same version?
Dec 21 22:14:51 <mrk377> Is this OS like lilo, where you have to update the location of the kernel image on each update somewhere?
Dec 21 22:23:02 <Son_Goku> I would not be surprised if Yocto's default setup for kernels is dumb-ish
Dec 21 22:23:15 <Son_Goku> but I haven't made a Yocto image recently, so hell if I know :)
Dec 21 22:26:50 <mrk377> I am stumped.  The rpm (kernel-image-3.14.57-yocto-standard-custom-3.14+git0+769b79eb20-r0) installs the /boot/bzImage-3.14.57-yocto-standard-custom image.
Dec 21 22:32:05 <Son_Goku> mrk377: does it have any scriptlets for actually configuring the bootloader?
Dec 21 22:32:27 <Son_Goku> rpm -q --scripts kernel-image-3.14.57-yocto-standard-custom
Dec 21 22:32:45 <mrk377> Son_Goku:  I dont' know.  It must have a script of some sort.
Dec 21 22:34:16 <mrk377> postuninstall scriptlet (using /bin/sh): # kernel-image-3.14.57-yocto-standard-custom - postrm if [ "$1" = "0" ] ; then update-alternatives --remove bzImage bzImage-3.14.57-yocto-standard-custom || true fi
Dec 21 22:35:46 <Son_Goku> eww
Dec 21 22:35:49 <Son_Goku> so it works using alternatives
Dec 21 22:35:55 <Son_Goku> that's... horrific
Dec 21 22:35:57 <mrk377> # kernel-image-3.14.57-yocto-standard-custom - postinst
Dec 21 22:36:06 <mrk377> 	update-alternatives --install /boot/bzImage bzImage /boot/bzImage-3.14.57-yocto-standard-custom 31414 || true
Dec 21 22:36:19 <Son_Goku> do you have an implementation of alternatives in your image?
Dec 21 22:36:28 <Son_Goku> for example, chkconfig provides one
Dec 21 22:36:33 <mrk377> yeah.
Dec 21 22:36:53 <Son_Goku> what does "ls -l /boot/bzImage" tell you?
Dec 21 22:37:25 <mrk377> lrwxrwxrwx    1 root     root            43 Dec 21 16:42 /boot/bzImage -> /boot/bzImage-3.14.57-yocto-standard-custom
Dec 21 22:37:39 <mrk377> Looks good to me!
Dec 21 22:38:46 <Son_Goku> what's your configured bootloader?
Dec 21 22:40:03 <mrk377> Just rebooted after re-running:update-alternatives --install /boot/bzImage bzImage /boot/bzImage-3.14.57-yocto-standard-custom 31414
Dec 21 22:40:08 <mrk377> standby
Dec 21 22:43:47 <mrk377> It is the standard yocto bootloader.
Dec 21 22:44:17 <mrk377> uboot
Dec 21 22:47:10 <mrk377> No change.  Hmmm...  I might roll a new image from scratch.  I was hoping to just install rpms
Dec 22 00:10:16 <bemo> looking in the mega-manual, should I expect tags/yocto-2.5 to exist? (the command shown is: "git checkout tags/yocto-2.5 -b poky_2.5")
Dec 22 00:16:56 <bemo> "git checkout -b sumo origin/sumo" doesn't seem to work for me either.
Dec 22 00:19:01 <bemo> ... looking at the branches, using "rocko" instead of "sumo" (based on releases listed on yoctoproject.org) seems to work
Dec 22 00:20:33 <ikkysleepy> is there any easy way to run a script at startup ? Is creating a service that calls a script the best way? or which files do I need to edit to run a script on startup?
