One final update for anyone who might run into this problem.
With all of my fiddling/twiddling I failed to get libquadmath to build under the `zeus` branch.  Unfortunately, my other layer dependencies only support `zeus` so it seems I will have to wait until they support a branch that can build `libquadmath`.
I am fairly certain there is just a simple mistake somewhere but, alas, I have been unable to find where that is.

Hi,

If you can come up with a reasonably simple reproducer and
it fails on a supported branch:
https://wiki.yoctoproject.org/wiki/Releases

then we'd appreciate if if you could report the bug in the YP Bugzilla:

https://wiki.yoctoproject.org/wiki/Bugzilla_Configuration_and_Bug_Tracking

Don't worry too much about getting every field right if you aren't familiar
with the overall project.


There's no guarantee that we'll get someone to work on it but
at least it's tracked and we might get to it at some point.

I will keep fiddling but I think we are onto something.
The interesting thing I found is that `libquadmath.so

IS being built for the nativesdk but NOT when I add `DEPENDS

Perhaps, because `FORTRAN = ""` is in the gcc_%.bb, maybe
that should be something less strict?
I might be screwing up my bbappend too...
My append is in
`meta-mylayer/recipes-devtools/gcc/gcc-runtime_%.bbappend`
Which is mapped correctly to $BBFILES n my layers `layer.conf`

Just inject that line via distro or local.conf

Hello,

so I'm a bit at a loss. I admit, I've not yet been using Yocto for a long time. I'm trying to use base-utils as provided by packagegroup-core-base-utils to have a more full featured set of base utils instead of busybox. It all builds just fine, however, whatever I do (using dunfell), it ends up with a kernel panic during boot.

I added the following to local.conf on a clean clone of poky:

INIT_MANAGER="systemd"

IMAGE_FSTYPES="live"

PREFERRED_PROVIDER_base-utils = "packagegroup-core-base-utils"
VIRTUAL-RUNTIME_base-utils = "packagegroup-core-base-utils"
VIRTUAL-RUNTIME_base-utils-hwclock = "util-linux-hwclock"
VIRTUAL-RUNTIME_base-utils-syslog = ""

Hi Paul,

Try adding:

VIRTUAL-RUNTIME_base-utils-syslog = "syslog"

as shown on:

https://git.yoctoproject.org/poky/tree/meta-poky/conf/local.conf.sample.extended#n371

I would expect that since you have systemd, you'd have the systemd journal as well so
you wouldn't need syslog but it would be good to do a sanity check.


If that doesn't help, show us what the kernel panic is saying.
Is this with a custom BSP and if so can you reproduce with qemux86-64?

Try the same things using poky on the master branch if you can.

../Randy

Does anyone have any idea how to get this to work?

Can you please let me know how to "forward SSH_AGENT into it to be able
to fetch from internal projects without the need to mount the key into the container."? I never did that before.

I use the following options within the Docker run command:
-v $SSH_AUTH_SOCK:/ssh.socket \
-e SSH_AUTH_SOCK=/ssh.socket \

Furthermore, I had to mount the .ssh folder into the container to make it working (be aware of security risk).
Additionally, you should check that uid, gid of the user in the container is the same on the host.

yeah something like that works, we use it for yoe which always uses
container to build

Is there a way we can fetch those approved header files from YOCTO SDK and filter it?

I am thinking like creating subset versioned module recipe and specify those approved header files and package only those files. Is there any better mechanism on packaging or filtering the SDK based on some rules to filter some header files?

Like for example in YoctoSDK, we have 2 modules
moduleA (A1.h, A2.h,A3.h and libA.so),
moduleB (B1.h, B2.h, B3.h and libB.so)
Lets say A3.h & B3.h are not approved in my Custom SDK, then in final Customer SDK we will only package
moduleA (A1.h, A2.h and libA.so), moduleB (B1.h, B2.h, and libB.so)

I want to keep YoctoSDK without any filters, so that A3.h/B3.h can be used for internal purposes without any issue.

Hi Praveen,

I'm not aware of anyone else doing that.

For libraries/recipes, you could just omit certain packages from the eSDK but you don't seem to want to do that.

What is your goal in filtering headers and libraries rather than say generating two SDKs:
one that is unrestricted and the other with limited APIs ?

That is, can you not package each moduleA as moduleA and moduleA-private using Yocto's packaging

mechanism with the *3.h files being in the private packages?

I don't work with the SDK very much so I could be out in left field but
if I am, hopefully someone will reply and straighten us both out!

I do something similar, my "problem" was that ssh needs the
.ssh/known_hosts file with a matching entry in addition to your
key/agent, but mounting the .ssh folder was not possible for me because
of permissions. Currently, I just created a little script that wraps
"oe-init-build-env" and populates the known_hosts file accordingly.

mkdir -p ~/.ssh

cat <<EOF >> ~/.ssh/known_hosts
git.example.com ssh-ed25519 <base64key>
EOF

I use my own Dockerfile based on crops/poky where I do the following,
which might be helpful if you also use this. It sets up the config
changes in /etc/skel/ since it creates users "on the fly" with
matching uid.

# Remove strict host key checking for ssh
# This is needed since the build will pull source over git-ssh
RUN mkdir -p /etc/skel/.ssh/
COPY ci-scripts/docker-stuff/config /etc/skel/.ssh/
RUN echo 'export GIT_SSH_COMMAND="ssh -o UserKnownHostsFile=/dev/null
-o StrictHostKeyChecking=no"' >> /etc/skel/.bashrc


The ci-scripts/docker-stuff/config file contains:
Host *
StrictHostKeyChecking no
UserKnownHostsFile=/dev/null

Now it was ages ago I set this up, and right now I can't really
understand why I basically do the same thing twice. So you'd have to
check which of the two things that actually solves the issue :-)

Cheers,
Erik

I use almost the same, just without submodules.

It should "just work" if ssh is able to find your key. I often build in
a docker container, so I have to forward SSH_AGENT into it to be able
to fetch from internal projects without the need to mount the key into
the container. I don't really have any insight for builds outside
docker, if git clone works, the bitbake fetcher should too.

But this results in the error:

<snip>

But I am able to clone the repo using git clone.
SSH key is already added to the Gitlab. There is no config file in my
~/.ssh. Do I need to create a config file? What should be the content
of the config file?

You should not need a ssh config file.

Can anyone please let me know how to resolve this?
Thanks in advance.

A question specifically to Denys, how can I actually get this into the mixin repo, and have commit rights to the branch? We've tested this quite well in private, and there are further enhancements coming up.

this could be an independent layer too.

Hello Bruce,

Another is to make that append conditional based on something you can test. i.e. test for kernel-cache in the SRC_URI, and if present, do the append. Or you could test for the defconfig in the SRC_URI and don't do the append. There may be other options for this, but without all the details of the recipes, I can't say for sure.
I have a few variations of that theme in meta-virtualization, since there's a broad range of kernel types supported (https://git.yoctoproject.org/meta-virtualization/tree/recipes-kernel/linux/linux-yocto_virtualization.inc).

I chose the variant based on SRC_URI, but used KERNEL_CONFIG_URI because I got endless recursion between SRC_URI and KERNEL_FEATURES in the kernel recipe I use.
I ended up with this function:

def insert_if_kernel_cache_available(feature, d):
import re
if d.getVar('KERNEL_CONFIG_URI'):
config_uri = d.getVar('KERNEL_CONFIG_URI')
kernel_cache = re.search("kernel-cache", config_uri)
if kernel_cache:
return feature
return ""

KERNEL_FEATURES:append = "${@insert_if_kernel_cache_available(' features/overlayfs/overlayfs.scc', d)}"

Many greetings,
Matthias

Hi Quentin,

Thank you very much for the review.

Also revert the changes with "git reset --hard" to

One change at a time please ☺️

Well, here, the two should go together. I admit my description is
probably misleading.

My initial "git checkout" was wrong (wrong path), so wasn't doing
anything. Now that "git checkout" works as expected, I need a way to
clean the branch after the docs are generated. Otherwise, I'll switch
branches in the rest of the script from an unclean state.

This should be done right after the git checkout. It's better to ensure what you build is clean that try to ensure the next oneto build has a clean env. Especially since checkouts can dirty the git repo I think (I've had this issue multiple times when switching between kernel branches far enough from one another).

Also git reset --hard is not enough. I use git clean -ffdx instead usually. Didn't have a problem with this one for a while now.

My point was just to undo the "git checkout" to fetch releases.txt from
"master", not to be a substitute for "make clean".  I can't do it right
after "git checkout" otherwise I'm not doing anything at all.

You have a valid point about a possible "dirty" git version though.
Fortunately, I checked and it seems that uncommitted changes have no
impact on the generated docs. I couldn't find any git commit anywhere.

Thanks
Michael.
