Estou tentando compilar o gcc. Eu baixei a versão mais recente do site do GCC (versão 6.3.0), mas estou tendo problemas para criar o gcc. Estou passando as seguintes opções para o script de configuração:
configure --prefix=<location I want to install> --disable-multilib --disable-linux-futex
Nota: Isto compila bem sem a opção de configuração --disable-linux-futex . Eu preciso passar --disable-linux-futex porque eu estou tentando usar o valgrind para depurar um programa que eu escrevi que faz uso do OpenMP, e eles me dizem que eu preciso do GCC compilado com essa opção. Depois de digitar make , a compilação começa e é executada com sucesso por um longo tempo, até que eu receba os seguintes erros:

# If this is the top-level multilib, build all the other

Parece que o problema é com o ranlib em ../.././gcc/libgcc_eh.a , mas não tenho a menor idéia do que fazer ou o que o ranlib deve fazer. Qualquer ajuda seria muito apreciada. Deixe-me saber se posso fornecer mais detalhes úteis sobre minha configuração.
