Musl-LFS:使用Musl作为LibcLinux From Scratch

# Musl-LFS Linux From Scratch using Musl as Libc and S6+S6-rc as init system This is based on the works of Linux From Scratch (http://www.linuxfromscratch.org), which use GLibc and SysVinit/systemD. Additional work was derived from Void Linux (https://voidlinux.org), Alpine Linux (https://alpinelinux.org), and Dragora Linux (https://dragora.org). For logging during development of tool chains, I used porg from http://porg.sourceforge.net/. The aim of this project is to create a create a Linux system using Musl (www.musl-libc.org) instead of GNU's Glibc and S6 (https://skarnet.org/) instead SysVinit. ## Supported Architectures <ul> <li>i686/i586 : Stable and tested. Stable enough to build Xorg, Qt5 (without QT-webengine), Rust, and Firefox.</li> <li>x86_64 : Stable and tested. Stable enough to build Xorg, Qt5, Rust, and Firefox.</li> <li>aarch64: Stable and tested. Stable enough to build Xorg, Qt5, Rust, and Firefox.</li> <li>armv7/armv6: Builds fine. Requires modification to suit target hardware.</li> </ul> ## Goals: <ul> <li> [x] Properly name patches to reflect origin (i.e. Alpine or void) </li> <li> [ ] Create a list for wget to download sources.</li> <li> [ ] Create md5s list for sources</li> <li> [ ] Update s6-rc & s6 to lastest version </li> <li> [x] Redesign tool chain build to avoid two build passes of binutils and GCC</li> <li> [ ] Generate HTML 'book' like LFS</li> <li> [ ] Add utmp/utmpx implementation</li> <li> [ ] Transition from pkgconfig to pkgconf</li> <li> [ ] Transition from gettext to gettext-tiny?</li> <li> [ ] POSIX compatibility </li> </ul> ## Tested Builds | Host | Target | Build Status | | ------------ | ----------- | -------------- | | i686-musl | i686-musl | Pass | | i686-glibc | i686-musl | Pending | | x86_64-musl | x86_64-musl | Pass | | x86_64-glibc | x86_64-musl | Pass | | aarch64-glibc | aarch64-musl | Pass | | armv7l-glibc | armv7l-musl | Pass | | armv7l-musl | armv7l-musl | Pending | | armv6-glibc | armv6-musl | Pending | | armv6-musl | armv6-musl | Pending | *ARM builds will need some modification based on specific hardware* ## Additional Required Packages If pursuing BLFS, some packages will fail to compile due certain implementions left out in the Musl C Library. <ul> <li>Musl C Library https://www.musl-libc.org/</li> <li>Musl-FTS https://github.com/pullmoll/musl-fts</li> <li>Musl-Obstack https://github.com/pullmoll/musl-obstack</li> <li>Musl-RPmatch https://github.com/pullmoll/musl-rpmatch</li> <li>Musl-Legacy-Compatibility Headers https://github.com/void-linux/void-packages/blob/master/srcpkgs/musl-legacy-compat </li> <li>Argp-Standalone https://github.com/jahrome/argp-standalone</li> </ul> ## Optional Packages: <ul> <li>LibreSSL (instead of OpenSSL) https://www.libressl.org/</li> <li>GNU Nano (Text Editor) https://www.nano-editor.org/ </li> </ul> ## Projects of Interest <ul> <li>gCompat - "The gcompat project provides a glibc-compatible runtime environment for distributions that use musl libc." https://code.foxkit.us/adelie/gcompat</li> <li> Locales - "Locale program for musl libc" https://github.com/rilian-la-te/musl-locales </li> <li>Mussel - "...the shortest and fastest script available today to build working cross compilers that target musl libc." https://github.com/firasuke/mussel </li> <li>shimmy - POSIX:registered: compatibility shims for Linux (and other environments) https://code.foxkit.us/adelie/shimmy</li> <li>gettext-tiny - It provides lightweight replacements for tools typically used from the GNU gettext suite. https://github.com/AdelieLinux/gettext-tiny</li> </ul> ## Layout <ul> <li>build-scripts - [WIP] Build scripts to use to semi-automate building /cross-tools, /tools, and the final system</li> <li>contrib - Additional sources that are hard to find or re-packed <li>doc - Build instructions to build a LFS installation that uses Musl instead of Glibc and S6 instead of SysVint.</li> <li>extra - Helpful scripts to mount, chroot, and umount a MLFS build.</li> <li>files - Files that will be needed during the build</li> <li>patches - All patches used to patch sources to work/recognize Musl C Library</li> <li>sources.list - List of sources to download </ul> ## Changelog (since 6.00) <ul> <li>Upgraded to GCC-10.2.0 and several other packages</li> <li>Added musl-rpmatch to build</li> <li>Add zstd to build</li> <li>Changed tool chain build flow to build binutils and GCC once</li> <li>Added nano text editor for tool chain - Helps with troubleshooting</li> <li>Updated patches and files directory scheme to reflect origins</li> <li>Removed porg.
