Licença: GPL-3.0.

Como executar:

$ time sudo bash scriptgcc-4.7.3_UBUNTU12_64BITS.sh

Tempo de compilação em um Acer Aspire 4540 AMD Athlon M300 4 GB: ~3 horas.

• Enviar nova versão

Versão 2 - Enviado por Bruno Medeiros em 26/05/2013

Changelog: Legal o script, mas não concordo com algumas coisas, como por exemplo deixar o prefix no /usr (isso é extremamente desaconselhado, somente o gestor de pacotes (dpkg ou rpm) deve colocar arquivos no /usr). Usei a primeira versão como base e criei um script que configura o prefix pra um lugar dentro do próprio home, o sudo é usado somente para instalar os pré-requisitos.

Também foi preciso incrementar o LD_LIBRARY_PATH pra executar o gcc-4.7, fiz isso no /etc/bash.bashrc mais ou menos assim (ajustar local para o prefix configurado):

export LD_LIBRARY_PATH=/home/brunojcm/gcc/4.7.3/target/lib:/home/brunojcm/gcc/4.7.3/target/lib64:$LD_LIBRARY_PATH
