Attualmente, in Fedora \u00e8 rigidamente prescritto l'uso di GCC per la costruzione di tutti i pacchetti, tranne nei casi in cui il pacchetto pu\u00f2 essere costruito solo con Clang\/LLVM.<\/p>\n<p>Il motivo per fornire la possibilit\u00e0 di costruire utilizzando Clang \u00e8 che alcuni progetti, ad esempio, <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=49485\">Firefox<\/a><\/noindex> e <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=41072\">Chromium<\/a><\/noindex>, durante lo sviluppo utilizzano Clang come compilatore principale e le costruzioni basate su di esso sono pi\u00f9 ben testate. L'uso di Clang per tali pacchetti permetter\u00e0 di evitare il recupero di errori che emergono durante la costruzione con GCC, cos\u00ec come il coordimento delle correzioni di questi errori con il progetto principale. La costruzione con GCC ha un impatto positivo sul mantenimento della portabilit\u00e0 del codice sviluppato con Clang, ma crea un carico maggiore per i manutentori e ritarda la pubblicazione degli aggiornamenti (ad esempio, Mozilla <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=43894\">proibisce<\/a><\/noindex> \u00e8 necessario utilizzare il marchio Firefox quando si applicano patch di terze parti, perci\u00f2 \u00e8 importante prima ottenere l'inclusione delle patch nel ramo principale e rilasciare l'aggiornamento solo dopo che sono stati apportati i correttivi upstream).<\/p>\n<p>Si osserva che sarebbe logico utilizzare Clang per i pacchetti per i quali questo compilatore \u00e8 pi\u00f9 adatto e utilizzato nel progetto principale. Per tali pacchetti si potrebbe ridurre il carico di manutenzione se la preparazione dei pacchetti fosse gestita dai rappresentanti del progetto principale. Se la compilazione del pacchetto \u00e8 effettuata da un rappresentante della comunit\u00e0, si dovrebbe offrire al maintainers la possibilit\u00e0 di scegliere il compilatore. Per i pacchetti i cui progetti principali non mostrano preferenze per un particolare compilatore, si raccomanda di mantenere lo status quo (compilando in GCC come prima).
