Cannot install kernel-devsrc

Asked 2021-Jun-07 at 11:16

I'm trying to set up my environment to use Yocto's generated SDK to compile my out-of-tree module, but for some reason, I'm getting an error.

cp: cannot stat 'arch/arm/kernel/module.lds': No such file or directory

I'm using Poky distribution and meta-raspberrypi which is needed because I'm using the RPI ZeroW board. Apart from this everything works fine. I'm able to compile the entire image and load it on the board.

Here is the line I've added to local.conf

TOOLCHAIN_TARGET_TASK_append = " kernel-devsrc"

as I've found in the documentation.

Also below you can find the whole log from the compilation.

Understanding bitbake default task

Asked 2021-Jun-05 at 23:13

I'm trying to familiarize myself with yocto for work, and I'm reading through "Embedded Linux Systems with The Yocto Project", which is a decent resource, but I think it fails to explain the bigger picture very well.

To familiarize myself with how bitbake works, I created a very simple layer with a recipe called condtest which simply prints out a variable:

ANSWER

Answered 2021-Jun-05 at 23:13

There is always an implied:

INHERIT += "base"

which includes base.bbclass and conf/bitbake.conf is also included. These provide many of the defaults you're relying upon. Placing an empty bitbake.conf alongside local.conf would do something quite different (and break many things but proves how much it does).

ANSWER

Answered 2021-May-26 at 10:28

You have two different files: a .bb and a .bbappend.

A .bb is the base recipe of one (or multiple) packages. It generally describe how to fetch, configure, compile, install files in a package for your target.

A .bbappend file is an 'append' file. It allows a meta (here meta-petalinux) to modify an existing recipe in another meta without copying it. A .bbappend can modify any steps of the bb file: source fetch, configure, compile, install...

You can for example create your own bbappend of Gstreamer, to enable pango (disbaled by default on my Yocto). The bbappend filename is gstreamer1.0-plugins-base_%.bbappend and only contains PACKAGECONFIG_append = "pango"

The Yocto Manual can give you more information on bbappend files here.

QUESTION

Yocto Dunfell error 'No recipes available for' with multiple machines in single custom meta layer

Asked 2021-May-09 at 14:42

I maintain a custom Yocto meta layer compatible with Dunfell. It supports a Microchip SAMA5D27 processor based board. I have several bbappend files in this layer that apply only to file from the meta-atmel and other Microchip specific packages.

Now, I want to re-use many parts of this custom meta layer and support a new processor from a different vendor. I have created my own new image recipe in my layer that does not include these bbappend files that are only relevant to Microchip.

The problem is that Yocto throws as error 'No recipes available for' regarding my bbappend files. The error seems to happen during parsing and does not consider whether I use the recipe or not in the current target.

I have searched extensively for a solution, but so far have come up empty. How can I use 1 meta-layer and maintain different bbappend files, while being able to switch MACHINE variables for different target builds? Thanks!

You cannot append to a recipe that does not exist in the first place.

If the recipes exist:

make sure that their layer is added to bblayers.conf.

QUESTION

Yocto : Custom colored output in recipes?

Asked 2021-Apr-24 at 10:03

Context

When I'm using bitbake to process recipes with Yocto, I'd like to be able to print useful output on the screen. There exist a few ways to do this so far, but they're not very practical. Let me enumerate the default options:

Using: bbinfo "my message" with bitbake --verbose
Using: bbdebug 1 "my message" with bitbake -D (scaling is possible for more debug levels)
Using: bbwarn "my message" with no extra flags

Problem

Using option (1) outputs a lot of unnecessary clutter on the terminal, and also suffers from having no colored output. Option (2) is colored, but unfortunately also captures a lot of debugging messages from the other build components, which floods the output. I've been using option (3) for now, as it makes my messages stand out without also enabling other irrelevant information from appearing.

So my question is, how can I enable custom logging (i.e. in green, or blue) for my own messages? It would make it easier for me to distinguish important output I want without accidentally enabling unnecessary information from appearing

...

ANSWER

Answered 2021-Apr-24 at 10:03

Bitbake is the one taking care of printing log messages in their appropriate colors. You could add new kinds of log messages if you want with different colors by modifying: https://gitlab.com/yoctoproject/poky/-/blob/master/bitbake/lib/bb/build.py#L475 seems to be where the bbwarn/bbdebug/bbplain/etc... shell commands are translated to Python's bb.warn, bb.debug, bb.plain, etc.. defined here: https://gitlab.com/yoctoproject/poky/-/blob/master/bitbake/lib/bb/__init__.py#L132-165 and whose colors and loglevels are defined in BBLogFormatter class defined here: https://gitlab.com/yoctoproject/poky/-/blob/master/bitbake/lib/bb/msg.py#L22

I'd personally try to add warning levels the same way as different debug levels are handled and then you can associate a warning level to a particular color.

This however modifies bitbake itself, which is not possible via bbappends or other btibake mechanisms as they are Python scripts.

Otherwise, I'm wondering if it would not be possible to just have your own logger defined in/for the recipes/tasks/functions you want to use it, e.g. have a bbclass which sets up everything you need with the Python logging module and just use this instead of bbwarn or bb.warn.

Vulnerabilities

No vulnerabilities reported

Install bitbake

You can download it from GitHub, GitLab.
You can use bitbake like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
