you have to provide more context to help you more, but usually /dev is populated with devtmpfs during kernel boot. and similarly /etc is mounted early on. So access permissions could be mounting issues perhaps.

Patch files before recipe is parsed

Paul Adams
 

There is a problem with the Yocto recipe for Python 3 in warrior. It
is missing ntpath in the list of core modules listed in
python3-manifest.json.

Since warrior is EOL, I was hoping to fix this by patching the
python3-manifest.json file but it doesn't work. I think the reason is
that the manifest file is read by an anonymous function in the recipe,
which I understand is executed during recipe parsing (which I assume
happens before the patches are applied).

I know the patch is being applied correctly because the content of
python3-manifest.json file is correct when I inspect it in the
build/tmp/work... directory.

My question is whether there is any method in bitbake to apply patches
early enough to fix this issue?


Qtwebengine recipe in yocto zeus (latest version) #yocto #zeus #qt

anthony.marchand@...
 

Hello.
I hope you're going well in this period.
I'm working with yocto (zeus version) with a soc i.MX6 and kernel 4.19. Actually, I meet a weird issue about the recipe "qtwebengine" in all of my projects that are using zeus version.
The compilation was working fine until there, but since approximatively two weeks, with no particular reason, whatever the project I want to compile, I'm unable to compile qtwebengine and making a rootfs image with it inside.

So I have tested:

1) bitbake qtwebengine
2) bitbake myimage

PS: myimage contain the recipe qtwebengine.

But whatever the bitbake commands 1 or 2, Bitbake shows me the same error I don't understand and this error follows:

I don't understand why bitbake don't find '<asm/errno.h>', because it is present in the kernel 4.19 and in my host system ubuntu 18. Furthermore, I don't understand the problem with run_ninja.

I try to change my PC for compilation, but I have got the same error. The PC I use to compile with bitbake got 20 cores intel xeon and 32GB of ram. I think the problem is not from here. :-)

Does someone already meet this problem?

Does someone know where could be the problem?

Thanks for all and best reguards: Anthony.


#yocto "zeus" #yocto

Monsees, Steven C (US)
 

 

This is probably a simple question, but since I am new to yocto there is a lot to learn…

 

How do I establish kernel access permissions for the “zeus” kernel so that when my application is up and running, (or an application startup script), can create read/write files for access/updating in the ”/etc” and “/dev” directories ?

 

In the few cases I do this I am seeing unable to open errors…

Note the same code appears to work correctly under “rocko”…

Issue related to .wic image

#yocto zeus X11 keyboard #yocto

Monsees, Steven C (US)
 

 

I am running zeus based image (that runs without the following error under  my rocko build), under zeus build I am now seeing the following :

 

The XKEYBOARD keymap compiler (xkbcomp) reports:

> Warning:          Unsupported high keycode 372 for name <I372> ignored

>                   X11 cannot support keycodes above 255.

>                   This warning only shows for the first high keycode.

Errors from xkbcomp are not fatal to the X server

 

Under: .../share/X11/xkb/keycodes/evfev I372 is defined as:

        // Extended keys that may be generated on "Internet" keyboards.

        // evdev has standardize names for these.

 

        <I372> = 372;   // #define KEY_FAVORITES           364

 

Is there a build option for this component I can tweak to correct for this ?

 

Thanks,

Steve

The issue with your suggestion is that it **replaces** the original

append to the variable iff the recipe is built for menzu-media, that's
what the line above does.

But this didn't work, only "media.patch" is unpacked and moreover the kernel recipe workdir does not contain a content as if unpack didn't work properly.
How can I do it ?

I would like to ask, is there any way to separate this package from the verification function?

merges from stable branches will in most cases work, if they are still alive.
Thanks for sharing. But I'm using official poky release from git so I
cannot cherry pick changes.
Or you have clone of poky repo and add changes on top from newest versions?
Locally, as developer you always have a local branch where you can cherry-pick
changes. With git submodules and repo tooling, you should use a local or
project specific clone of poky. Or move all updates and changes to your own
layers, but I find this doesn't scale and instead branching in git works
better.

How to create new variable in Yocto to use it in a recipe ?

Bel Hadj Salem Talel
 

Hi All,

I'm not trying to export or create a variable inside a recipe because that's easy and not my case.
But I want to create a variable that a user can define in local.conf or in other conf files and a recipe that checks the value of that variable and do some stuff with it like:
python (){
 a = d.getVar('MY_VARIABLE' or '')
}
How can I do this?
Thanks, Talel


Re: python bump

Martin Jansa
 

If you don't really need 3.8 and 3.7.5 from warrior would be good enough for you, then backporting it to thud was relatively straightforward as implemented in:
and as it's in a separate layer it doesn't make your main distro layer more ugly or difficult to maintain (just drop backports layers when upgrading to newer release instead of trying to find out all backported bits and pieces across a whole set of layers).

But even this "small" upgrade from 3.6 to 3.7 introduces ABI change as shown in:
so it's better to upgrade completely to a new release if possible at all.

Re: Error when building eSDK for a `docker load`able tarball

Hi,

And as far as I understand you tried to build some extensible SDK against an x86-64 container.

Please note, that my SDK most likely contains a bit more than the "standard" stuff[0], but this should not make much of a difference here.

[0] https://gitlab.com/meta-layers/meta-resy/-/blob/dunfell/recipes-core/packagegroups/nativesdk-packagegroup-sdk-host.bbappend

I take a container-x86-64:

bitbake app-container-image-mosquitto-oci [1]

[1] https://pastebin.com/T9hX1H8f

bitbake app-container-image-mosquitto-oci -c populate_sdk [2]

[2] https://pastebin.com/eujc57DG

bitbake app-container-image-mosquitto-oci -c populate_sdk_ext

breaks in a similar way[3]

[3] https://pastebin.com/rV9ewZa9

So it looks like it's extensible SDK specific.

Can you please try with the "standard" sdk instead of the extensible sdk to see if this works for you?

You might want to play with IMAGE_CONTAINER_NO_DUMMY = "1" which is defined in poky/meta/classes/image-container.bbclass and try to build a container with a kernel as a workaround in case you build an eSDK.

Robert

You should rather move to a yocto release that has the needed python, backporting major pieces like that is difficult to impossible.
