Building a yocto image for RPi3 - raspberry-pi

Recently I started with yocto-project to build images for raspberry-pi.
I cloned poky and meta-raspberrypi under a directory named as yocto_project on my ubuntu host. Initiated the build using source oe-init-build-env rpi-build.
The first image I created the rpi-basic-image which was a successful attempt.
Upon booting RPi with the image I got a CLI based interface, but the problem is few commands are missing. Came to know by-default all the packages didn't get combine with image, we need to add it manually for example systemd.
If I run bitbake-layers show-recipes I get long list of all the recipes available for RPi. So I added the text IMAGE_INSTALL_append = " systemd" after reading some documents online to append systemd. After this when I bitbake rpi-basic-image got error as ERROR: Nothing RPOVIDES 'systemd' (but /path_to/rpi-basic-image.bb RDEPENDS on or otherwise requires it)
ERROR: systemd was skipped: 'systemd' not in DISTRO_FEATURES
ERROR: Required build target 'rpi-basic-image' has no buildable providers
Don't have clue, why I get this error. How to resolve it. Also do I have to manually add those packages/recipes using build/local.conf to get all the commands.
Need a good explanation/guidance .

From Selecting an Initialization Manager - Yocto Development Manual:
DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
You can set those variables in your local.conf.

Bitbake understanding the EXCLUDE_FROM_WORLD mechanism

I'm developing on Yocto 2.4 rockowith a BSP given by my provider. I'm trying to build modemmanager from the meta-openembedded layer, included in the meta-oe sub layer.
The configure task fail and give me as error :
checking for gobject-introspection...
configure: error: gobject-introspection-1.0 is not installed
After some search I've installed the libgirepository1.0-dev package on my host machine. But the error is always present.
I've continued investigations, and find in my recipe log the line :
DEBUG: EXCLUDE FROM WORLD: virtual:native:/home/test/share/sc20_linux/poky/meta/recipes-gnome/gobject-introspection/gobject-introspection_1.52.1.bb
I've tried to find which recipe excludes the dependency, with no success.
Can you help me to understand how works the EXCLUDE_FROM_WORLD mechanism ?
Thanks for your help.
I suspect that is debug output and doesn't mean the recipe is excluded. Have you looked at the modemmanager recipe to see if it has a DEPENDS on gobject-introspection-native and perhaps gobject-introspection? If not, or the PACKAGECONFIG isn't set, try adding the DEPENDS or enabling the PACKGECONFIG?
Also, have you tried simply building "bitbake object-introspection-native" and "bitbake object-introspection". You should get an error about why they ar disabled if you try and build them directly and they are excluded/disabled for some reason.

I'm trying to run this command "bitbake-layers show-recipes"

I'm trying to setup Yocto project in my linux system. I have added two layers which point outside the Yocto poky folder.
I'm following build steps from here:
https://www.yoctoproject.org/docs/2.7/brief-yoctoprojectqs/brief-yoctoprojectqs.html
I am trying to run the following command "bitbake-layers show-recipes 'ara-'*"
I'm getting this error
ERROR: ExpansionError during parsing /home/XXX/YYYYY/codebase/apd-source/meta-openembedded/meta-oe/recipes-support/syslog-ng/syslog-ng_3.6.4.bb
But I'm expecting output something like this:
***Parsing recipes..done.
=== Matching recipes: ===
ara-com-examples:
meta-ara 1.0.0
ara-com-fusion-example:
meta-ara 1.0.0
ara-com-gen:***
.
.
.
.
.
This error indicates bitabake failed to parse the recipe and could be due to syntax error from the recipe. But I have encounter this issue even without any error in my recipes. Honestly the don't know why that happened and that could be some issue with the build environment. Not sure.
In this situation, can you try
1. Remove the build directory and also ssttate cache directory.
2. Execute the setup environment script and rebuild
Try with the above steps and check issue resolved. And before that make sure you don't have any syntax error in the syslog_ng recipe , check do you have any bbappend recieps for syslog_ng in your layer or any other layers and they don't have any syntax errors.

core-image-minimal has bluetooth

I am trying to build core-image-minimal receipe for iMx7 (Yocto project), the image gets successfully built but it has bluetooth, caam and lot of other stuff. How can I remove these from including in the minimal-image?
core-image-minimal should only have things required for just booting nothing else, somehow other packages are getting added. I didnt add anything in my local.config file.
MACHINE = "imx7dsabresd"
bluetooth and wifi are enabled here:
imx7dsabresd.conf
You can add the following to your local.conf to remove bluetooth:
MACHINE_FEATURES_remove = "bluetooth"
CAAM is enabled in the kernel config here:
defconfig
To change the kernel configuration you can either provide a new defconfig or use a configuration fragment. The following steps describe how to create a config fragment.
Run the following command and deselect the bluetooth related config options:
bitbake -c menuconfig virtual/kernel
Run the following command to generate fragment.cfg in ${WORKDIR}
bitbake -c diffconfig virtual/kernel
At this point if you do not have your own layer, create one by following this guide:
Creating Your Own Layer
Create the directory for the .bbappend and the configuration fragment:
mkdir -p ${PATH_TO_YOUR_LAYER}/recipes-kernel/linux/linux-fslc-imx/linux-fslc-imx/
Move fragment.cfg from ${WORKDIR} to ${PATH_TO_YOUR_LAYER}/recipes-kernel/linux/linux-fslc-imx/linux-fslc-imx/
Create a ${PATH_TO_YOUR_LAYER}/recipes-kernel/linux/linux-fslc-imx_%.bbappend (assuming linux-fslc-imx is the correct kernel recipe for this board) and place the following in it:
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SRC_URI += "file://fragment.cfg"
Additionally, you may find the Creating Configuration Fragments section of the manual helpful.
For more information about bbappends see:
mega-manual
You do not mention which machine you are building for, but I suspect it has bluetooth enabled in the MACHINE_FEATURES. I also didn't look at the bb file for core-image-minimal closely, so could be something else.

How to include irdadump into Yocto (Poky) irda-utils 0.9.18 package

Please excuse my lack of knowledge and incorrect use of terminology. I
am looking to include irdadump in my build image within Yocto.
I modified the
/poky/meta/recipes-connectivity/irda-utils/irda-utils_0.9.18.bb file to
include irdadump in the list of targets to be built.
INITSCRIPT_NAME = "irattach"
INITSCRIPT_PARAMS = "defaults 20"
TARGETS ??= "irattach irdaping irdadump"
do_compile () {
for t in ${TARGETS}; do
oe_runmake -C $t
done
}
However the bitbake process fails which comes down to the dependency of
pkg-config and glib 2.0 required for idradump.
I did a quick search online and noticed that there was a separate .bb
file for irdadump:
http://cgit.openembedded.org/openembedded/plain/recipes/irda-utils/
I tried to replicate this however was still faced with compiling issues.
Could anyone give me a helping hand on including irdadump to my
irda-utils package?
Thank you
To add irda-utils to your build image, just add IMAGE_INSTALL_append in your conf/local.conf file.Next time when you will run Bitbake,it will include irda-utlis package in your build image.
IMAGE_INSTALL_append = " irda-utils"

Yocto Image build fails because "nothing RPROVIDES libavresample"

I am trying to build a custom Yocto image based on fsl-image-gui for my iMX6 based board SECO A62J. I use Hob to do this.
After having selected my machine, my layers and my image, I custom my packages list by adding chromium. This automatically selects libexif and libav which are Chromium dependencies. The build of the packages is successful
The last step is the build of the image itself, and this is where my problem appears. I select the packages I want to include in my image, including Chromium, libexif and libav (and its dependencies).
And I got those errors :
Nothing RPROVIDES 'libavresample' (but
/home/adrien/fsl-release-bsp/build_anna/recipes/images/fsl-image-gui-edited-20170131-144607.bb RDEPENDS on or otherwise requires it)
and
Required build target 'fsl-image-gui-edited-20170131-144607' has no
buildable providers. Missing or unbuildable dependency chain was:
['fsl-image-gui-edited-20170131-144607', 'libavresample']
However, the library libavresample.so is built successfully and can be found under my build directory in sysroots/"machine_name"/usr/lib/
Why Yocto can't find and include this library in my image, What am I missing here?
In your local.conf :
LICENSE_FLAGS_WHITELIST += " commercial"
