\u00c8 stato pubblicato il rilascio degli strumenti GNU Mes 0.26, che forniscono il processo di bootstrap per GCC e consentono di ottenere un ciclo di ricompilazione chiuso dai codici sorgente. Gli strumenti risolvono il problema della compilazione iniziale verificata del compilatore nelle distribuzioni, interrompendo la catena di ricompilazione ciclica (per compilare il compilatore sono necessari file eseguibili di un compilatore gi\u00e0 compilato, e le compilazioni binarie del compilatore sono potenziali fonti di backdoor nascoste, il che non consente di garantire completamente l'integrit\u00e0 delle compilazioni dai codici sorgente di riferimento). <\/p>\n
GNU Mes offre un interprete autonomo per il linguaggio Scheme, scritto in C, e un semplice compilatore per il linguaggio C (MesCC), scritto in Scheme. Entrambi i componenti sono reciprocamente compilabili. L'interprete Scheme consente di compilare il compilatore C MesCC, che a sua volta consente di costruire una versione ridotta del compilatore TinyCC (tcc), le cui capacit\u00e0 sono gi\u00e0 sufficienti per compilare GCC. <\/p>\n
L'interprete del linguaggio Scheme \u00e8 molto compatto, occupa circa 5000 righe di codice nella sottosetta pi\u00f9 semplice del linguaggio C e pu\u00f2 essere convertito in un file eseguibile utilizzando il traduttore universale M2-Planet o un semplice compilatore C, costruito utilizzando l'assemblatore auto-costruibile hex0, che non richiede dipendenze esterne. Inoltre, l'interprete include un completo garbage collector e fornisce una libreria di moduli caricabili. Il progetto sviluppa anche la libreria C Mes, sufficiente per compilare glibc 2.2.5, binutils 2.20.1 e gcc 2.95.3, necessari per il dispiegamento della distribuzione Guix per piattaforme i686-linux, x86_64-linux, armhf-linux e aarch64-linux, utilizzando solo i sorgenti (Full Source Bootstrap). <\/p>\n
In questo nuovo rilascio \u00e8 stata aggiunta la supporto per moduli completamente compatibili con Guile e sono state fornite le possibilit\u00e0 di avvio di Gash e Gash-Utils. \u00c8 avvenuto il passaggio da assert all'uso delle eccezioni. \u00c8 stato aggiunto il supporto per le espressioni regolari. Sono stati implementati nove nuovi moduli (ftw, i18n, receive, regex, io ports, bytevectors, srfi-2, srfi-11 e srfi-37). Sono state aggiunte 46 nuove funzioni, tra cui chdir, clone-port, closedir, concatenate, drop, environ, execle, mkdir, opendir, partition, pipe, readdir, reduce, rmdir, seek, span, sleep, umask, uname e utimes. Nei prossimi rilasci \u00e8 previsto il supporto per il bootstrap di NixOS solo dai codici sorgente, la possibilit\u00e0 di bootstrap gcc 4.6.4, cos\u00ec come il supporto per la compilazione completa dell'intero sistema dai codici sorgente in ambienti Linux basati su architetture armhf e riscv64. \u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d
