Hello, I am not sure if you've found the OpenEmbedded Layer Index [0] yet, but that's a good resource and an example of what can be done. I believe the source code is available [1] and I've toyed with the idea of getting it working locally (although I've not had the time to do so).
That could be a part of what you're looking for, at least. Hope that helps, Aaron 0) https://layers.openembedded.org/layerindex/branch/master/recipes/ 1) http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/tree/layerindex On Thu, Oct 12, 2017 at 5:34 AM, Bernd <prof7...@gmail.com> wrote: > I am a new user for a few weeks now, trying to make a customized image > for a toradex colibri-vf module, so far I have succeeded in the > following disciplines: > > * adding the 3rd party layers that I need > * making my own layers > * using a .bbappend to patch the device tree > * using a .bbappend to workaround a bug(?) in one of the freescale layers > * writing my own recipe to install a python script > * writing recipes for pulling additional python packages with pypi and > setuptools3 > * writing my own image recipe > * making it boot and run on the target platform > > During this learning experience I have made the following observations > of circumstances that made it especially hard for me to get things > done, I'm not yet really sure if this is a documentation issue or if > it is really a missing feature but I feel I could have had a much > *much* easier time learning and understanding the concepts and > relationships and the inner workings of existing layers upon which I > want to build my system if the following things were possible (and/or > if they are already possible they should be documented in the very > first chapter of the documentation): > > * Finding the *file path* of an existing recipe (or append file or > class) *by its name* and also all existing .bbappends for it, i > imagine something simple like bitbake --show-paths foo-bar would > output me the small list of absolute paths of recipe files by the name > foo-bar and all matching .bbappend files in the order in which they > would be applied, it would show me only this small list of paths and > not dump 100kb of unrelated information along with it.
