Yea, that's the sort of approach I was expecting. Getting musl to build is the easy bit, making it usable as the system libc for an entire image is the difficult bit. I think at least initially we'd need a few bbappends in a meta-musl layer to fix packages which don't compile out-of-the-box with musl. I don't think musl fills the nommu gap though - from the comparison page I linked to it says musl doesn't support mmu-less microcontrollers. -- Paul Barker Email: p...@paulbarker.me.uk http://www.paulbarker.me.uk -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
