Installazione di gcc47 come default usando Homebrew

Sto cercando di installare gcc47 come compilatore predefinito usando homebrew. Posso installare correttamente gcc47, ma aggiunge un suffisso -4.7 su tutti i suoi binari. Se provo a collegarlo in / usr / local / bin, le cose si complicano. Considera questo:

$ which gcc
/usr/bin/gcc
$ gcc --version

Se vuoi fare qualcosa di un po 'più semplice da ripristinare in seguito, puoi sempre fare un alias nel tuo file bashrc.

alias gcc gcc-4.7

Questo convertirà automaticamente tutto per te dalla riga di comando. Il rovescio della medaglia è che funziona solo quando il tuo bashrc è usato e solo per il tuo utente (che potrebbe anche essere un positivo).
