musl is mainly useful for tiny systems, a 40 MB partition is such a huge amount of space that the size of the C library no longer matters much. The size benefit of replacing glibc with musl is around 2 MB. A partition with an -Os build of Yocto with glibc+systemd (sic) is around 9 MB, together with bootloader and kernel this all fits in a 16 MB flash. Use compression for kernel and root filesystem and everything fits in a 8 MB flash. > Ross cu Adrian -- _______________________________________________ Openembedded-core mailing list [email protected] http://lists.openembedded.org/mailman/listinfo/openembedded-core
