What changes should make to enable dlt-system.
In build folder dlt-system application is not generating.
Manually by using command: cmake -D with dlt-system=ON it will generate but I need to generate while building please look at recipie image
Your recipe supports dlt-system via PACKAGECONFIG.
In order to activate that flags in the compilation process, you just need to add dlt-system to PACKAGECONFIG in .bb or .bbappend file to the recipe:
PACKAGECONFIG_append = " dlt-system"
If you want to add it from local.conf:
PACKAGECONFIG_pn-name_append = " dlt-system"
Just change name with your recipe name.
This will add -DWITH_DLT_SYSTEM=ON to EXTRA_OECMAKE which is used in do_configure of the cmake class.
I am following ROS–Unity Integration tutorial for ROS2. I coppied unity_robotics_demo and unity_robotics_demo_msgs to my src folder from here. When building unity_robotics_demo_msgs gives me an error. I did source install/setup.bash and colcon build. Error:
CMake Error at CMakeLists.txt:7 (find_package):

I am not sure how to add the installation prefix. In foxy/share there is rosidl_default_generators:
I am trying to install a custom application on my Yocto build.
I currently use a Raspberry Pi 4 64 bit setup, for which I want PyQt5 to display an application directly on the frame buffer (so no windowing manager or desktop envoirement).
My current build with Yocto completes and boots on the Raspberry Pi. All the Qt5 libraries are also present in the root fs after the bitbake build.
Although, I'm having problems getting a custom layer, that adds a custom recipe with a custom application to also copy over to the destination root fs.
My custom layer is called 'meta-rpikms' with recipe 'recipes-kms-qt-app' which contains the application bb files. This files is called 'basicquick_0.1.bb' and has the following contents (this test application tries to add a EGLFS friendly Qt5 applicaiton, i'll try PyQt5 later):
SUMMARY = "Simple Qt5 Quick application"
#SECTION = "examples"
LICENSE = "MIT"
#PACKAGE_ARCH = "all"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
DEPENDS += "qtbase qtdeclarative qtquickcontrols2"
SRCREV = "${AUTOREV}"
SRC_URI = "git://github.com/shigmas/BasicQuick.git"
S = "${WORKDIR}/git"
require recipes-qt/qt5/qt5.inc
do_install() {
install -d ${D}${bindir_native}
install -m 0755 BasicQuick ${D}${bindir_native}
}
FILES_${PN} += "${bindir_native}"
When I bitbake the custom layer of my meta-rpikms (called 'qt5-kms-rpi-image'), it does compute. When I take a look at the 'image_initial_manifest' file, my custom application does show up, suggesting that it does compile and try to install the application:
# This file was generated automatically and contains the packages
# passed on to the package manager in order to create the rootfs.
# Format:
# <package_type>,<package_name>
# where:
# <package_type> can be:
# 'mip' = must install package
# 'aop' = attempt only package
# 'mlp' = multilib package
# 'lgp' = language package
mip,basicquick
mip,bluez5
mip,bridge-utils
mip,hostapd
mip, bla bla bla etc etc etc.
And if I take a look in: '~/builds/pyqt5_try1/poky/rpi64-build/tmp/work/cortexa72-poky-linux/basicquick/0.1-r0', the expected files do show up. Also suggesting that it does atleast build the application. This makes the think that the 'install' arguments in my .bb file are pointing to the wrong folder.
In my basicquick_*.bb file this is to make the directory and install (copy) the built files:
install -d ${D}${bindir_native}
install -m 0755 BasicQuick ${D}${bindir_native}
I used the 'bitbake -e' command to trace the variable D and bindir_native:
D="/home/mats/builds/pyqt5_try1/poky/rpi64-build/tmp/work/raspberrypi4_64-poky-linux/qt5-kms-rpi-image/1.0-r0/image"
bindir_native="/usr/bin"
This seems okay at first glance, but when I manually follow the destination of the variable 'D', there is no 'images' folder created. I also wonder why everybody installs their custom applications on ${D}/usr/bin? Should this not be written to the build/tmp/deploy directory? Or am I missing a step here.
So, in this 'qt5-kms-rpi-image/1.0-r0' folder, there is a folder called 'deploy-qt5-kms-rpi-image-image-complete', which contains a rootfs. But there also is a rootfs folder in the 'qt5-kms-rpi-image/1.0-r0' folder. Both of these rootfs's do not contain any mention of my basicquick application, or a BasicQuick folder being created in /usr/bin.
Also, the rootfs found in the "build/tmp/deploy/images/raspberrypi4-64/qt5-kms-rpi-image-raspberrypi4-64.tar.bz2" does not contain any mention of the basicquick application being present in the filesystem.
Does anybody have any clues on what I am missing? Am I just not copying my files to the correct location? Or does the final deploy image end up somewhere else from where I am expecting it?
Thanks in advance.
With kind regards,
Mats de Waard
I new to Yocto so there are probably some mistakes and misunderstanding that I've had, I appreciate if you can help.
So, I want to add a new package (tar file) to my custom image.
I have followed steps and steps in manual and some online instructions. While running: "bitbake mylayer", the layer is built fine but I got this error while building the image, here is the log file:
DEBUG: Executing python function rootfs_deb_bad_recommendations
DEBUG: Python function rootfs_deb_bad_recommendations finished

This may mean that the package is missing, has been obsoleted, or

E: Package 'mylayer' has no installation candidate

And here is mylayer.bb:
SUMMARY = ""
LICENSE = "CLOSE"
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI += "file://mypackage.tar"
Also, I have included the package in conf/local.conf:
IMAGE_INSTALL_append += " mylayer"
So beside trying to figure out how to solve this problem, I also have some questions:
I have read some example of .bb, and they mentioned about LIC_FILES_CHKSUM. The mypackage.tar.gz is a package to install a platform for the device and I don't know much about the source code, so I don't know if it is necessary to include the license? Or how to know that this package need license to install?
In some answer I found online, there is one saying that I need to include PACKAGE_CLASSES ?= "package_deb" (they want to install the .deb file), so probably in my case I will need PACKAGE_CLASSES ?= "package.tar" right? I have tried to change variable, but it still not successful.
The mypackage.tar includes some deb files. If I could not install mypackage.tar, can I instead install these .deb files? Can I put it all in mylayer.bb?
Thank you in advanced, I have tried to study much documents as I could but I get so confused and there is huge amount of information to digest.
First, before answering your questions
Let me mention some best practices advice for you:
Rename the recipe to some significant name related to you compressed package.
Naming the recipe to mylayer confuses Yocto users, because there is the term layer also.
Regarding you recipe:
There is no need for FILESEXTRAPATHS because the recipe path is added automatically to Yocto paths.
FILESEXTRAPATHS it is required for .bbappend files.
You need to override the do_install task function, it does nothing by default.
do_install is the first essential task to make sure that your sources are included in the final image.
Beside that, when specifying a compressed source file into SRC_URI, yocto automatically decompresses it.
This is mentioned here.
So, here what your recipe should look like:
SUMMARY = ""
LICENSE = "CLOSED"
# Prevent Yocto from decompressing the file
SRC_URI = "file://mypackage.tar;unpack=0"
do_install(){
# Create the opt folder into the final image, ${D} is ${WORKDIR}/image
install -d ${D}/opt
# Copy the compressed file there; You can change permissions as you want
install -m 0755 ${WORKDIR}/mypackage.tar ${D}/opt
}
# Very important to specify what you installed in (do_install)
FILES_${PN} = "/opt/*"
Now, when you run IMAGE_INSTALL_append += " mylayer" your file will be installed.
Regarding your questions:
You mentioned that your compressed file contains .deb files, I assume that no license checksum is needed. Also, I understand that you may wanted to point to SRC_URI[md5sum] or other checksums for the full package. That is also not needed for local files, it is used to check for the integrity of online sources.
PACKAGE_CLASSES as mentioned here, is used by the system to know in what type the data should be packaged. By the data I mean the data that you installed with do_install. That data get packaged for according to your PACKAGE_CLASSES variable, for example, to deb file. And that is used, along side with all other recipes packages, to build the final rootfs.
Yes, if you are installing the tar file into the image and then unpack it to install all deb files, for example, with dpkg. You can use the bin_package class to do that, now the recipe must be changed for that reason:
Decompress the tar file and provide the deb files in the local files folder.
Add all deb files to SRC_URI
Inherit the bin_package class
Specify the files to be packaged.
Your recipe should look like this:
SUMMARY = ""
LICENSE = "CLOSED"
SRC_URI = "file://deb_file1.deb \
file://deb_file2.deb"
# No need to `do_install` , it is invoked by the (bin_package) class
FILES_${PN} = ""
Important:
About FILES_${PN}, you need to add all what the deb installed into the image folder
Example, if your deb file installs this:
/usr/bin/hello
/etc/hello.cfg
Specify them:
FILES_${PN} = "/usr/bin/*"
FILES_${PN} += "/etc/*"
Use * so if other deb files install files into the same folder as others it will include all.
Working on a couple of recipe's that have file conflicts with base packages.I am trying to figure out how to force override the conflicts. In particular I am overwriting the /etc/network/interfaces file with a custom one within my recipe. How do I tell bitbake that the file(s) in my package are to take precedence over the file(s) from the base packages?
I am using RPM as the package management subsystem with in the build environment.
Running transaction test
Error: Transaction check error:
file /etc/network/interfaces conflicts between attempted installs of router-1.0-r0.noarch and init-ifupdown-1.0-r7.qemuarm64
file /etc/udhcpc.d/50default conflicts between attempted installs of router-1.0-r0.noarch and busybox-udhcpc-1.24.1-r0.aarch64
You can't. Either don't install one of the packages in the conflict or override the original recipe's file with a bbappend.
