redhat 7 tem gcc 4.8.5.
Eu quero atualizá-lo para 4.9. Para isso usei o comando abaixo
sudo yum install devtoolset-3-gcc.x86_64
E recebi a resposta abaixo

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Eu verifiquei que o mpfr está instalado

Mas ambos já existem no meu sistema. Estou faltando alguma coisa aqui? Como posso instalar o gcc versão 4.9 no RHEL 7?

Não o ano 2000 "redhat 7", mas RHEL 7:Red Hat Enterprise Linux 7
Nota: devtoolset-3 não é uma atualização do gcc/g++, mas apenas um dos compiladores extras disponíveis para EL7. Ou seja, você pode ter quantas versões do gcc quiser, instaladas ao mesmo tempo. Por favor, certifique-se de ter o compilador do sistema instalado: #yum install gcc-c++
Requer: libmpfr.so.1()(64 bits)
Requer: libgmp.so.3()(64 bits)
"devtoolset-3" é antigo (RHEL 6): 1) Instale esses pacotes (construído para EL7, 'janeiro de 2015') .... compat-libgmp-4.3.1-1.sl7.x86_64.rpm, compat-libmpfr-2.4.1-1.sl7.x86_64.rpm
Link, compatibilidade-libgmphttps://drive.google.com/file/d/0B7S255p3kFXNZFJDdWtkV3RyZTA/view?usp=sharing... e compat-libmpfrhttps://drive.google.com/file/d/0B7S255p3kFXNV0FoOVlPemRBS0k/view?usp=sharing
# cd Downloads/ && yum install compat-libgmp-4.3.1-1.sl7.x86_64.rpm compat-libmpfr-2.4.1-1.sl7.x86_64.rpm
2) Não há necessidade do devtoolset-3 completo. Isso instalará gcc-4.9 / g++-4.9 :
# yum install devtoolset-3-gcc-c++... total de ~4 pacotes. ... 'gfortran':# yum install devtoolset-3-gcc-gfortran
Habilitar gcc-4.9, g++-4.9 : $ scl enable devtoolset-3 bash... e $ gcc -vdirá "gcc versão 4.9" (a configuração é válida até você sair do terminal).
