Newbie problem with paths just building Poky

[Pauli Heikkinen]

Hi,

According to https://github.com/siemens/kas/issues/175 this should be a place not just for patches and announcements but also for Q&A so here goes...

I made a basic kas file like this:

header:

version: 20

build_system: openembedded

machine: genericx86-64

distro: poky

repos:

# Initially we use poky to build.

# Later on we may be able to dump poky and go with a curated list of repos and our own distro.

# That will have an effect on paths in general as well, as poky has its own "funny" structure.

poky:

url: "git://git.yoctoproject.org/git/poky"

tag: "scarthgap-5.0.14"

kas checkout works, but kas build does not:

kas build censored.config.yaml

Now, clearly it's looking in the wrong place - poky/conf instead of poky/build/conf - but what am I doing wrong and how do I fix this, or is this some weird bug?

I could use kas for just checkout, it would still help keep everything organized, but I'd like to do the build step as well if I only only knew how to make it work:

Sorry,

Actually the conf files were created in build/conf, not in poky/build/conf. Which just adds to my confusion :(

This is a multi-layer repo, so you need to specify the layers you want to use here:

  poky:
    ...
    layers:
      meta:
      meta-poly:
      ...

Thanks, that was indeed the problem.

Would it make sense for kas to detect this and warn the user?

Hmm, that would mean doing the work that bitbake does, checking for
layer.conf, once more in kas. Not too nice in the "fast" path. In an
ideal world, bitbake would give some additional hint...
