Dec 29 03:53:30 <Gordio> Hi.
Dec 29 03:54:16 <Gordio> Why with this https://bpaste.net/show/aa1c6dedff39 bblayers I get image without python/perl etc...?
Dec 29 03:54:40 <Gordio> Builded with `bitbake rpi-hwup-image`
Dec 29 07:05:07 <learningc> What are the packages I can add for images display in framebuffer?
Dec 29 07:06:01 <learningc> I want to display something on the rgb LCD screen
Dec 29 07:11:01 <learningc> What's the difference between -dev and -sdk as in core-image-lsb-dev and core-image-lsb-sdk?
Dec 29 07:43:53 <anujm> learningc: lsb-sdk includes toolchain and dev headers as well
Dec 29 07:44:10 <anujm> you can check what is included in: meta/recipes-extended/images/core-image-lsb-dev.bb
Dec 29 07:45:05 <learningc> What is toolchain?
Dec 29 07:46:13 <anujm> Compiler, autotools etc.
Dec 29 07:49:39 <learningc> I see. What is the purpose of the -dev image since it does not contain the compiler?
Dec 29 07:52:37 <anujm> I believe that it includes dev headers for packages as well which aren't included in the image by default
Dec 29 07:56:35 <learningc> You mean the -sdk image does not contain dev headers for packages?
Dec 29 09:13:05 <mckoan> good morning
Dec 29 09:13:38 <nayfe> morning
Dec 29 09:32:08 <yocti> New news from stackoverflow: busybox error while building using yocto <https://stackoverflow.com/questions/48020218/busybox-error-while-building-using-yocto>
Dec 29 09:36:21 <mkilivan> Hi,  I've created a recipe to build homeridge and modified the avahi.inc file in order to fix libdns_sd.o and dns_sd.h error. (The patch is here https://pastebin.com/5Q2eFEcw) Also, I added the following to the homebridge recipe. DEPENDS_${PN}  = "avahi libavahi-dnssd libnss-mdns"
Dec 29 09:36:46 <mkilivan> But still I got the same error.
Dec 29 09:40:36 <mkilivan> dns_sd.h is not in /poky/build/tmp/work/cortexa7hf-neon-vfpv4-poky-linux-gnueabi/homebridge/0.4.33-r0/recipe-sysroot/usr/include folder. It seems DEPENDS didn't work. Am I missing something?
Dec 29 10:31:08 <ttllkk> I am trying to compile a recipe (NetworkManager) which requires python3-pygobject-native during compilation. I have 'DEPENDS = python3-pyobject-native' but it is still not working. Could anyone help me ?
Dec 29 10:41:13 <nayfe> mkilivan>  you can't use DEPENDS_${PN} but DEPENDS
Dec 29 10:42:02 <nayfe> mkilivan: DEPENDS if for recipes, whereas RDEPENDS_${PN} is for packages
Dec 29 10:45:27 <nayfe> ttllkk: you don't use  http://cgit.openembedded.org/meta-openembedded/tree/meta-networking/recipes-connectivity/networkmanager/networkmanager_1.4.4.bb?h=rocko ?
Dec 29 10:52:27 <Ox4> hello guys
Dec 29 10:52:55 <Ox4> Is it possible to apply patch accoring to the image name? If so, how can I do that?
Dec 29 10:55:41 <ttllkk> nayfe: No, I require a newer version
Dec 29 10:56:14 <ttllkk> But I think I have the problem very localiced
Dec 29 10:56:37 <ttllkk> It is just that 'GObject' it is not available at compilatino time for the SDK.. (like if python3-pygobject-native was not being installed)
Dec 29 10:57:04 <ttllkk> The NetworkManager configure tries to run: "$PYTHON" -c 'from gi.repository import GObject' and checks the return code to see if it is available
Dec 29 10:57:23 <ttllkk> If I try that on 'bitbake -c devshell NetworkManager' error I see that there is an ImportError
Dec 29 10:58:18 <ttllkk> However if I use 'find <networkmanager specific SDK directory> -name "*GObject*" I get some files, which make me thing that GObject should in fact be available (also, well I did add it to the DEPENDS of the recipe)
Dec 29 10:58:40 <ttllkk> This was working fine in Yocto 2.2, but fails now in Yocto 2.4. I believe the new feature of having recipe independent SDKs is the root of my problem
Dec 29 11:00:02 <nayfe> ttllkk: do you inherit gobject-introspection ?
Dec 29 11:00:35 <ttllkk> Yes, this is the recipe: https://pastebin.com/zryYY6Fj
Dec 29 11:01:38 <ttllkk> By the way, would   poky@yoctoproject.org be the correct mailing list to post thiskind of problems?
Dec 29 11:02:24 <yocti> New news from stackoverflow: Couldn't find shared library provider <https://stackoverflow.com/questions/48021440/couldnt-find-shared-library-provider>
Dec 29 11:05:36 <nayfe> ttllkk: i think openembedded-core@lists.openembedded.org  is more appropriate
Dec 29 11:06:46 <ttllkk> even though the python3-pygobject recipe is in the poky layer?
Dec 29 11:09:50 <nayfe> ttllkk: see http://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#how-to-submit-a-change
Dec 29 11:14:22 <nayfe> ttllkk: btw gobject introspection is for documentation generation i suppose? do you need it?
Dec 29 11:18:02 <ttllkk> Probably not critical, but I would like to leave things as close as possible as they were in Yocto 2.2
Dec 29 11:18:18 <ttllkk> But yes,  if aI am not able to fix this I would just dislabe introspection in the configure
Dec 29 11:18:26 <ttllkk> thanks for the link
Dec 29 11:34:13 <ttllkk> Any idea how to make PYTHON list all the available modules/libraries?
Dec 29 11:34:27 <ttllkk> I am comparing the sysroot in yocto 2.2 and 2.4 and they seem identical..
Dec 29 11:34:46 <ttllkk> I would like to understand the process python3 uses to execute the 'from gi.repository import GObject'
Dec 29 11:40:47 <nayfe> ttllkk: it comes from https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/configure.ac#n1284
Dec 29 11:41:10 <ttllkk> Yes, the '"$PYTHON" -c 'from gi.repository import GObject'' is what f ails
Dec 29 11:41:18 <ttllkk> I can reproduce it on -c devshell
Dec 29 11:41:22 <ttllkk> But in yocto 2.2 it works
Dec 29 11:41:50 <ttllkk> and I am comparing the sysroots and they look the same.. they both have the .typelib  file, the both have the /gi/_gojbect/__init__.py...
Dec 29 11:42:41 <ttllkk> The error it gives is 'ImportError: cannot import name GObject, introspection typelib not found'
Dec 29 11:54:09 <mkilivan> nayfe Can I add a package to a DEPENDS list? DEPENDS = "avahi libavahi-dnssd " failed with the following error:
Dec 29 11:54:27 <mkilivan> ERROR: Nothing PROVIDES 'libavahi-dnssd'
Dec 29 11:54:41 <mkilivan> avahi RPROVIDES libavahi-dnssd
Dec 29 11:54:51 <nayfe> <mkilivan> DEPENDS is for recipes
Dec 29 11:55:11 <mkilivan> I've added libavahi-dnssd to package list in avavi receipe.
Dec 29 12:02:38 <yocti> New news from stackoverflow: Process for keeping an OE/Yocto image updated <https://stackoverflow.com/questions/48021974/process-for-keeping-an-oe-yocto-image-updated>
Dec 29 12:04:22 <nayfe> ttllkk: introspection maintainer is kanavin, maybe he'll help :)
Dec 29 12:04:44 <ttllkk> Thank you
Dec 29 12:05:09 <mkilivan> nayfe perhaps I should not modify the avahi recipe. Basically, homebridge requires libavahi-compat-libdnssd-dev installed on Linux. So, I am trying to get equivalent on yocto. Can you suggest a better way of doing that?
Dec 29 12:07:09 <mkilivan> By the way, I noticed that issue was discussed here https://www.yoctoproject.org/irc/%23yocto.2014-08-12.log.html, I wonder if manuel_ build the code at the end. :)
Dec 29 12:07:14 <nayfe> mkilivan: there are DEPENDS when recipe needs another to compile, and RDEPENDS to tell some package needs another package in runtime
Dec 29 12:08:54 <nayfe> mkilivan: when you see "dns_sd.h is not in ..." it means you need to add the recipes responsible to fetch dns_sd.h in DEPENDS of your recipe (not RDEPENDS)
Dec 29 12:09:07 <mkilivan> The thing is avahi doesn't provide necessary files (I think) so I've edit a package to provide extra files. See patch is here https://pastebin.com/5Q2eFEcw
Dec 29 12:13:12 <mkilivan> now DEPENDS = "avahi libavahi-dnssd "
Dec 29 12:13:46 <mkilivan> ERROR: Nothing PROVIDES 'libavahi-dnssd' (but /local/mnt/workspace/raspberrypi-rocko/poky/build/workspace/recipes/homebridge/homebridge_0.4.33.bb DEPENDS on or otherwis e requires it). Close matches:   avahi RPROVIDES libavahi-dnssd
Dec 29 12:17:21 <nayfe> DEPENDS = "avahi" is enough
Dec 29 12:17:46 <nayfe> as DEPENDS works with recipes, and you are modifying avahi recipe
Dec 29 12:18:55 <nayfe> but maybe you need extra steps in do_install() to copy include files from WORKDIR to ${D}
Dec 29 12:19:17 <mkilivan> OK, so how can make avahi recipe to add extra files? Because my changes didn't work.
Dec 29 12:22:01 <nayfe> in avahi.inc, do_install() part, add something like install <options> ${D}/${includedir}  ; cp -rf ${WORKDIR}/...../dns_sd.h ${D}/${includedir}/
Dec 29 12:23:03 <nayfe> before you can check in /tmp/work/...../avahi/.../image if dns_sd.h is already present
Dec 29 12:25:51 <mkilivan> yes I can see that dns_sd.h is in /tmp/work/.../avahi/.../image/usr/include/avahi-compat-libdns_sd/ folder
Dec 29 12:26:53 <mkilivan> and libdns_sd.so is in /tmp/work/.../avahi/.../image/usr/lib folder
Dec 29 12:44:19 <nayfe> mkilivan: so its FILES_libavahi-dnssd = "${libdir}/libdns_sd.so.* ${includedir}/avahi-compat-libdns_sd/dns_sd.h"
Dec 29 12:45:32 <mkilivan> nayfe I am trying to add these files in do_install() but couldn't managed yet.
Dec 29 12:46:48 <nayfe> mkilivan: if files are already installed (probably due to autotools_do_install), you dont need more, check with oe-pkgdata-util list-pkg-files -p avahi if dns_sd.h is listed
Dec 29 12:51:38 <mkilivan> nayfe Thanks, I can see dns_sd.h is in the output. So do you think that files are already installed then, right?
Dec 29 12:52:47 <nayfe> mkilivan: indeed, so if you add DEPENDS = "avahi" to homeridge recipe, you should find dns_sd.h as well in sysroot-recipe
Dec 29 12:53:02 <mkilivan> nayfe in do_install() there is following line:
Dec 29 12:53:04 <mkilivan>  rm -rf ${D}${libdir}/avahi
Dec 29 12:53:28 <mkilivan> Does that mean these files has been deleted during install?
Dec 29 12:55:41 <nayfe> mkilivan: indeed
Dec 29 12:59:20 <mkilivan> nayfe Thanks, I will have a look at it to understand the recipe first. At least I can see what the problem is with your help. Much appreciated.
Dec 29 13:01:54 <nayfe> mkilivan: np, did you check recipe-sysroot folder from homeridge work dir for dns_sd.h file ?
Dec 29 13:02:30 <mkilivan> I did, dns_sd.h is not there.
Dec 29 13:09:42 <nayfe> mkilivan: do you think you can share homeridge recipe ?
Dec 29 13:15:03 <mkilivan> Sure, https://pastebin.com/X0awTquc
Dec 29 13:30:18 <nayfe> mkilivan: did you change FILES_libavahi-dnssd = "${libdir}/libdns_sd.so.* ${includedir}/avahi-compat-libdns_sd/dns_sd.h"    (add avahi-compat-libdns_sd folder) ?
Dec 29 14:58:24 <dafna> Hi, I coudn't find ant documentation explaining the differences between the distribution features "x11" and "x11-base"
Dec 29 14:58:58 <dafna> it's wrritan in the manual that "x11-base" is a x11 with minimal environment
Dec 29 14:59:22 <dafna> couldn't understand what is means
Dec 29 15:03:27 <kergoth> x11-base isn't a distro feature, it's an image feature
Dec 29 15:03:39 <kergoth> it controls what's installed, not how things are built / what the distro supports
Dec 29 15:09:24 <dafna> ok, I see that x11 is both a distro and an image feature
Dec 29 15:15:24 <dafna> so adding x11 only as image feature , install x11 libraries related but does not initialize the server ?
Dec 29 15:23:42 <mkilivan> nayfe: I changed FILES_libavahi-dnssd to add avahi-compat-libdns_sd folder and this did a trick. Now, I can see the header file in homebridge's work folder.
Dec 29 15:23:44 <mkilivan> ./recipe-sysroot/usr/include/avahi-compat-libdns_sd/dns_sd.h
Dec 29 15:24:12 <nayfe> mkilivan: nice
Dec 29 15:24:18 <mkilivan> I still got the same error though.
Dec 29 15:24:19 <mkilivan> ../src/mdns.hpp:32:10: fatal error: dns_sd.h: No such file or directory
Dec 29 15:24:56 <mkilivan> should I add avahi-compat-libdns_sd in compiler's include folder?
Dec 29 15:30:49 <nayfe> mkilivan indeed
Dec 29 16:16:36 <learningc> What's the purpose of headers when adding -dev after the image name?
Dec 29 16:17:34 <learningc> I mean, how do we use the image-dev as compared to image without dev?
Dec 29 16:27:21 <kergoth> learningc: uh, you'd use the headers the same way you use headers on any linux system, for development
Dec 29 16:29:04 <learningc> kergoth, Then how do we compile the app?
Dec 29 16:29:11 <kergoth> what app?
Dec 29 16:29:35 <kergoth> headers for a library are used by projects linking against that library
Dec 29 16:29:39 <learningc> If it's for development, this means we are developing an app?
Dec 29 16:29:43 <kergoth> if you don't know what you want to build, i cant help you
Dec 29 16:30:07 <kergoth> it's an image with headers included for you to use in your development. if you don't know waht you want to code, i don't know what to tell  you
Dec 29 16:30:15 <kergoth> it's not an image intended to develop some specific thing
Dec 29 16:30:29 <learningc> I see
Dec 29 16:31:39 <learningc> So, how do we link against the library?
Dec 29 16:31:47 <kergoth> i don't have time to teach you how to code
Dec 29 16:31:54 <kergoth> google is your friend
Dec 29 16:32:41 <learningc> I know how to code. just don't understand what the -dev image used for
Dec 29 16:33:14 <learningc> The headers and libraries are provided
Dec 29 16:34:02 <learningc> But do we need a linker to link to the library?
Dec 29 16:36:32 <learningc> What I mean is, does the -dev image has linker in it? Or am I misunderstanding the use of the -dev image?
Dec 29 20:56:21 <dafna> Hi, i'm a bit confused, the do_package_write comes after the do_package ?
Dec 29 20:57:37 <dafna> it's a bit confusing , in the manual the do_package_write is described first
Dec 29 20:57:57 <dafna> http://www.yoctoproject.org/docs/1.6/ref-manual/ref-manual.html#package-feeds-dev-environment
