FreeBSD-udviklere bogen \"ITIL Foundation. ITIL 4 Edition\". Dens opgave er at forklare n\u00f8glebegreberne og l\u00e6gge grundlaget for efterf\u00f8lgende studier af avancerede programmer.<\/a><\/noindex> planen for at fjerne GCC 4.2.1 fra kildekoderne i det grundl\u00e6ggende FreeBSD-system. GCC-komponenterne vil blive fjernet inden for grenene af FreeBSD 13, som kun vil inkludere compileren Clang. GCC kan installeres fra ports, hvis \u00f8nskes, GCC 9<\/a><\/noindex>, 7<\/a><\/noindex> og 8<\/a><\/noindex>, samt de der allerede er blevet klassificeret som for\u00e6ldede udgivelser<\/a><\/noindex> GCC 4.8<\/a><\/noindex>, 5<\/a><\/noindex>, 6<\/a><\/noindex> og 7<\/a><\/noindex>.<\/p>\n

Arkitekturer, der er afh\u00e6ngige af GCC og ikke kan overg\u00e5 til Clang, vil blive tilbudt at skifte til eksterne v\u00e6rkt\u00f8jer, der installeres fra ports. I forbindelse med forberedelserne til fjernelsen af GCC fra det grundl\u00e6ggende system planl\u00e6gges der at forbedre integrationen af byggev\u00e6rkt\u00f8jet i det grundl\u00e6ggende system med eksterne v\u00e6rkt\u00f8jer. For eksempel er muligheden for at bygge med gcc 6.4 fra ports allerede blevet tilf\u00f8jet til det kontinuerlige integrationssystem for amd64-arkitekturen, hvilket kan bruges som grundlag for at overs\u00e6tte andre arkitekturer.<\/p>\n

Det skal huskes, at siden FreeBSD 10 er det grundl\u00e6ggende system for i386, AMD64 og ARM-arkitekturerne blevet skiftet til som standard at levere Clang-compiler og libc++-biblioteket udviklet af LLVM-projektet. GCC og libstdc++ for de n\u00e6vnte arkitekturer stoppede med at blive bygget som en del af det grundl\u00e6ggende system, men fortsatte med at blive leveret som standard for powerpc, mips, mips64 og sparc64-arkitekturerne, og kunne ogs\u00e5 installeres ved ombygning med flagsene WITH_GCC og WITH_GNUCXX. Leveringen af den for\u00e6ldede version GCC 4.2.1 var for\u00e5rsaget af licensbegr\u00e6nsninger.<\/p>\n

FreeBSD kunne ikke overg\u00e5 til en nyere version af GCC, da den siden version 4.2.2 var overg\u00e5et<\/a><\/noindex> til GPLv3-licensen, og integrationen af GCC 4.2.2 blev hindret af inkompatibilitet mellem runtime-komponenterne i GCC og BSD-licensen. Senere, i version GCC 4.4, blev denne inkompatibilitet blevet afhjulpet<\/a><\/noindex>, men det blev anerkendt som umuligt<\/a><\/noindex> p\u00e5 grund af mods\u00e6tningerne til m\u00e5lene for FreeBSD-projektet<\/a><\/noindex> og \u00f8nsket om ikke at p\u00e5l\u00e6gge yderligere begr\u00e6nsninger p\u00e5 brugerne, s\u00e5som forbud mod tvangsm\u00e6ssig brug<\/a><\/noindex>.<\/p>\n

Afskaffelsesprocessen for GCC i basis-systemet vil blive opdelt i flere faser og vare i 9 m\u00e5neder, hvilket vil give udviklerne, der er bundet til GCC-arkitekturer (powerpc, mips, mips64 og sparc64), tid til at migrere til Clang eller skifte til brugen af ekstern v\u00e6rkt\u00f8jsudvikling. Den f\u00f8rste fase starter den 31. august og vil f\u00f8re til, at gcc 4.2.1 udelukkes fra bygningen i det automatiserede integrationssystem, samt stop af brugen af flaget '\u2013Werror' for de platforme der er knyttet til GCC og som standard deaktivere bygning af GCC ved k\u00f8rsel af 'make universe'. <\/p>\n

Den 31. december 2019 vil GCC-bygningen v\u00e6re deaktiveret som standard, men kan stadig aktiveres ved angivelse af bestemte flag. Den 31. marts 2020 vil GCC blive fjernet fra SVN-repositoriet, og den 31. maj vil alle platforme, der ikke d\u00e6kkes af systemet til kontinuerlig integration, der ikke underst\u00f8tter LLVM eller ikke er blevet migreret til brug af eksterne bygv\u00e6rkt\u00f8jer, blive fjernet fra SVN. Den 31. juli 2020 vil den endelige fjernelse fra SVN af alle resterende platforme, der kr\u00e6ver brug af eksterne v\u00e6rkt\u00f8jer, men ikke underst\u00f8ttes i relasebyggekoderne, finde sted.<\/p>\n
