Basile" <blueness@...too.org> To: gentoo-embedded@...ts.gentoo.org, gentoo-hardened@...ts.gentoo.org, musl@...ts.openwall.com Subject: yet another alternative libc Hi everyone, I just thought I'd let everyone know that I've built a musl stage4 for amd64 and put it on the mirrors . If you don't know about musl, you can read about it here . Its yet another libc which aims to be a slim and fast. I've got a stage4 (kinda/sorta). It is not made using catalyst but rather starts from a musl chroot and builds a new chroot using a ROOT=rootfs emerge -ev @system technique. The scripts are on the releng repo . Right now there are lots of packages which do not immediately build with musl. Mostly these are due to header locations, gnu-isms, gnulib (which assumes way too much about internal implementations) and at least one bug in musl or gcc (depending on who you ask --- exit() compiled with --stack-protector-all). The patches are on the hardened-dev::musl overlay . They are "quickies" and may need work if any are to go upstream. A few points about the stage: 1) it doesn't use busybox for its core utilities. I like a robust native development environment from which you can build. 2) Despite the fact that the profile is under hardened, it is still a vanilla stage. I'm working on getting it hardened, but a few packages break when we turn on pie, ssp, relro and/or bind_now. Enjoy or ignore at your discretion. --Tony Refs.  http://distfiles.gentoo.org/experimental/amd64/musl/  http://www.musl-libc.org/  http://git.overlays.gentoo.org/gitweb/?p=proj/releng.git;a=tree;f=tools-musl  http://git.overlays.gentoo.org/gitweb/?p=proj/hardened-dev.git;a=tree -- Anthony G.
