musl C library layer for OpenEmbedded

This layer provides musl as an alternative to system C library for OpenEmbedded based distributions along with uClibc and eglibc/glibc

Getting Started

git clone git://github.com/openembedded/openembedded-core.git
cd openembedded-core
git clone git://github.com/openembedded/bitbake.git
git clone git://github.com/kraj/meta-musl.git

$ . ./oe-init-build-env

Edit conf/bblayers.conf to add meta-musl to layer mix e.g.

BBLAYERS ?= " \
  /home/kraj/openembedded-core/meta-musl \
  /home/kraj/openembedded-core/meta \
  "

Building

Below we build for qemuarm machine as an example

$ MACHINE=qemuarm TCLIBC=musl bitbake core-image-minimal
$ MACHINE=qemux86 TCLIBC=musl bitbake core-image-weston
$ MACHINE=qemux86 TCLIBC=musl bitbake core-image-sato

Running

$ TCLIBC=musl runqemu qemuarm

Limitations

Only works with OE-Core >= 1.9

Currently core-image-minimal is buildable/bootable for MIPS, ARM, PPC, x86, x86_64 based qemu machines, core-image-sato and core-image-weston boots with qemux86 MACHINE variable and TCLIBC variables can also be set in conf/local.conf to avoid typing it on commandline on any bitbake invocation

Upstreaming

Mailing List

Send pull requests to openembedded-devel@lists.openembedded.org with '[meta-musl]' in the subject'

When sending single patches, please use something like

git send-email -M -1 --to openembedded-devel@lists.openembedded.org --subject-prefix=meta-musl][PATCH

Forking via github

You are encouraged to fork the mirror on github to share your patches, this is preferred for patch sets consisting of more than one patch. Other services like gitorious, repo.or.cz or self hosted setups are of course accepted as well, 'git fetch ' works the same on all of them. We recommend github because it is free, easy to use, has been proven to be reliable and has a really good web GUI.
