Desenvolvedores do FreeBSD apresentaram<\/a><\/noindex> plano para remo\u00e7\u00e3o do GCC 4.2.1 dos c\u00f3digos fonte do sistema base FreeBSD. Os componentes do GCC ser\u00e3o removidos antes do branch FreeBSD 13, que incluir\u00e1 apenas o compilador Clang. O GCC poder\u00e1 ser instalado a partir dos ports, onde \u00e9 oferecido GCC 9<\/a><\/noindex>, 7<\/a><\/noindex> e 8<\/a><\/noindex>, assim como aqueles j\u00e1 classificados como obsoletos lan\u00e7amentos<\/a><\/noindex> GCC 4.8<\/a><\/noindex>, 5<\/a><\/noindex>, 6<\/a><\/noindex> e 7<\/a><\/noindex>.<\/p>\n

Arquiteturas que dependem do GCC e n\u00e3o podem migrar para o Clang ser\u00e3o aconselhadas a mudar para ferramentas externas, instaladas a partir dos ports. Como parte dos preparativos para a remo\u00e7\u00e3o do GCC do sistema base, planeja-se melhorar a integra\u00e7\u00e3o do sistema de build do sistema base com ferramentas externas. Por exemplo, para a arquitetura amd64, j\u00e1 foi adicionada ao sistema de integra\u00e7\u00e3o cont\u00ednua a capacidade de compilar usando gcc 6.4 a partir dos ports, que pode ser utilizada como base para portar outras arquiteturas.<\/p>\n

Lembramos que desde o FreeBSD 10, o sistema base para as arquiteturas i386, AMD64 e ARM foi alterado para fornecer por padr\u00e3o o compilador Clang e a biblioteca libc++ desenvolvida pelo projeto LLVM. O GCC e libstdc++ para as arquiteturas mencionadas deixaram de ser compilados como parte do sistema base, mas continuaram a ser fornecidos por padr\u00e3o para arquiteturas powerpc, mips, mips64 e sparc64, al\u00e9m de poderem ser instalados ao recompilar com os flags WITH_GCC e WITH_GNUCXX. A entrega da vers\u00e3o obsoleta GCC 4.2.1 foi motivada por restri\u00e7\u00f5es de licen\u00e7a.<\/p>\n

O FreeBSD n\u00e3o p\u00f4de migrar para uma vers\u00e3o mais recente do GCC, pois a partir do lan\u00e7amento 4.2.2, o GCC foi migrado<\/a><\/noindex> para a licen\u00e7a GPLv3 e a integra\u00e7\u00e3o do GCC 4.2.2 foi dificultada pela incompatibilidade dos componentes de runtime do GCC com a licen\u00e7a BSD. Posteriormente, na vers\u00e3o GCC 4.4, esta incompatibilidade foi resolvida<\/a><\/noindex>, mas a adi\u00e7\u00e3o de componentes sob licen\u00e7a GPLv3 ao sistema base FreeBSD foi considerada imposs\u00edvel<\/a><\/noindex> devido a conflitos com os objetivos do projeto FreeBSD<\/a><\/noindex> e a relut\u00e2ncia em impor restri\u00e7\u00f5es adicionais aos usu\u00e1rios, como a proibi\u00e7\u00e3o de tivoiza\u00e7\u00e3o<\/a><\/noindex>.<\/p>\n

O processo de remo\u00e7\u00e3o do GCC do sistema base ser\u00e1 dividido em v\u00e1rias etapas e durar\u00e1 9 meses, o que dar\u00e1 aos desenvolvedores das arquiteturas compat\u00edveis com GCC (powerpc, mips, mips64 e sparc64) tempo para migrar para o Clang ou para usar ferramentas externas. A primeira etapa come\u00e7ar\u00e1 em 31 de agosto e resultar\u00e1 na remo\u00e7\u00e3o do gcc 4.2.1 da constru\u00e7\u00e3o no sistema de integra\u00e7\u00e3o cont\u00ednua, al\u00e9m da interrup\u00e7\u00e3o da aplica\u00e7\u00e3o da flag \u2018-Werror\u2019 para as plataformas compat\u00edveis com GCC e na desativa\u00e7\u00e3o padr\u00e3o da constru\u00e7\u00e3o do GCC ao executar \u2018make universe\u2019. <\/p>\n

Em 31 de dezembro de 2019, a build do GCC ser\u00e1 desativada por padr\u00e3o, mas poder\u00e1 ser reativada com a especifica\u00e7\u00e3o de certas flags. Em 31 de mar\u00e7o de 2020, o GCC ser\u00e1 removido do reposit\u00f3rio SVN, e em 31 de maio, todas as plataformas que n\u00e3o est\u00e3o cobertas pelo sistema de integra\u00e7\u00e3o cont\u00ednua, que n\u00e3o suportam LLVM ou que n\u00e3o migraram para o uso de ferramentas de build externas, ser\u00e3o removidas do SVN. Em 31 de julho de 2020, a remo\u00e7\u00e3o final de todas as plataformas restantes que requerem ferramentas de build externas, mas que n\u00e3o t\u00eam suporte nos scripts de forma\u00e7\u00e3o de lan\u00e7amentos, ser\u00e1 realizada.<\/p>\n
