Como construir gcc-6.x.0 em x64 sem “especificação desconhecida” reclamar?

Question

Eu segui as etapas descritas no LFS , mas permaneci em

g++: fatal error: unknown spec function ‘gt’

Para ser específico, foi construído em x86_64-unknown-linux-gnu com gmp-6.1.2, mpc-1.0.3 e mpfr-3.1.5.

Como resolver este problema? Obrigado.

O problema é provável em algumas variáveis ambientais da sua sessão. Você pode tentar executar o comando make em um ambiente limpo:

env -i PATH=/bin:/usr/bin make
