Udgivet er version 0.26 af GNU Mes v\u00e6rkt\u00f8jet, der underst\u00f8tter bootstrapping-processen for GCC og muligg\u00f8r en lukket cyklus for genkompilering fra kildekoder. V\u00e6rkt\u00f8jet adresserer behovet for en verificeret initial kompileringsbygning i distributioner, hvilket bryder cyklen af cyklisk genkompilering (for at bygge en compiler kr\u00e6ves eksekverbare filer fra en allerede bygget compiler, og bin\u00e6re builds af kompileren kan v\u00e6re en potentiel kilde til skjulte bagd\u00f8re, hvilket forhindrer en fuldst\u00e6ndig garanti for integriteten af builds fra reference kildekoder). <\/p>\n
I GNU Mes tilbydes en selvforsynende (self-hosting) interpreter for sproget Scheme, skrevet i C, samt en simpel compiler for C-sproget (MesCC), skrevet i Scheme. Begge komponenter kan gensamles. Scheme-interpreteren muligg\u00f8r opbygningen af C-kompilatoren MesCC, som derefter kan bygge en besk\u00e5ret version af kompilatoren TinyCC (tcc), hvis funktionalitet allerede er tilstr\u00e6kkelig til at bygge GCC. <\/p>\n
Interpreteren for sproget Scheme er meget kompakt og best\u00e5r af ca. 5000 kodelinjer p\u00e5 det enkleste underr\u00e6kke af C-sproget og kan omdannes til et eksekverbart fil ved hj\u00e6lp af den universelle overs\u00e6tter M2-Planet eller en simpel C-compiler, bygget ved hj\u00e6lp af den selvopbyggelige assembler hex0, som ikke kr\u00e6ver eksterne afh\u00e6ngigheder. Desuden inkluderer interpretereren en fuld garbage collector og tilbyder et bibliotek af indl\u00e6selige moduler. Projektet udvikler ogs\u00e5 C-biblioteket Mes C, som er tilstr\u00e6kkeligt til at bygge glibc 2.2.5, binutils 2.20.1 og gcc 2.95.3, som er n\u00f8dvendige for at implementere distributionen Guix til platformene i686-linux, x86_64-linux, armhf-linux og aarch64-linux, ved kun at bruge kildekoder (Full Source Bootstrap). <\/p>\n
Den nye version tilf\u00f8jer underst\u00f8ttelse af fuldt kompatible moduler med Guile og muligheden for at k\u00f8re Gash og Gash-Utils. Der er sket en overgang fra assert til brug af undtagelser. Underst\u00f8ttelse af regul\u00e6re udtryk er blevet tilf\u00f8jet. Ni nye moduler er implementeret (ftw, i18n, receive, regex, io ports, bytevectors, srfi-2, srfi-11 og srfi-37). 46 nye funktioner er tilf\u00f8jet, herunder chdir, clone-port, closedir, concatenate, drop, environ, execle, mkdir, opendir, partition, pipe, readdir, reduce, rmdir, seek, span, sleep, umask, uname og utimes. I kommende udgivelser forventes der st\u00f8tte til bootstrapping af NixOS udelukkende fra kildekoder, mulighed for bootstrapping af gcc 4.6.4 samt st\u00f8tte til en fuld bygning af hele systemet fra kildekoder i Linux-milj\u00f8er baseret p\u00e5 arkitekturerne armhf og riscv64. \u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0432\u044b\u043f\u0443\u0441\u043a
