There were interest in other threads in having musl as an alternative

Blimey Khem that was quick. :)

I wonder if it's worth splitting this out into its own layer though
I thought about it and since class/conf changes that need to go in into OE-core
first I kept it as it is (lazyness too). I think once the core support
is available in OE-core
we can spin the recipes into a layer of its own.

(with fixes done via bbappends) so that it's easy for multiple people
to contribute to. It would also mean it doesn't need rebasing onto
master all the time.

I'd definitely like to get involved with this. In particular I can
ensure opkg (both current release and development branch) work with
musl and see if some of my preferred software from meta-oe will build
(vim, htop, etc).
start with what we have. Once master opens up I would propose the needed
changes to OE-core and spin a layer
I did a quick 'bitbake -k core-image-minimal' to see what's currently
failing. Full logs and config at

Build Configuration:

I can see for util-linux that we need to implement qsort_r().

Busybox probably just needs config changes:

I already have local fix for busy box.
Excellent! I'm currently looking at util-linux.

I think we should ask for a new repo to be setup on for meta-musl. I'm happy to be one of the
maintainers for that, I hope that you are as well and maybe a couple
of the others who were interested could also help. I think having a
few people as maintainers is important as we're all already fairly
busy on other projects.

Once the layer is setup we can move the recipes off your branch of
oe-core and into the layer as time permits. That would just leave the
changes which need to go into oe-core on your branch.

Does that sound like a sensible plan?
