With Xcode 4.x and earlier, GCC was a GCC frontend to LLVM, so it actually worked for compiling Asterisk. Looks like that's changed for Xcode 5. Now gcc is just an alias for clang (which seems like a very wrong headed thing to do, IMO).

GCC 4.8 from Homebrew works great for 12 and trunk. There are a couple of issues compiling 1.8 and 11, though. I bet apple-gcc42 will work, but I haven't had a chance to try it.

I'm a bit crammed for time now, but post-Astricon I may be able to look into back porting fixes in 12 to get 1.8 and 11 compiling on OS X again.

For 12 and trunk, here are the homebrew packages I install (from memory; might be missing a few):

brew tap leedm777/asterisk
brew tap homebrew/versions
brew install pjsip iksemel unixodbc srtp gcc48 sqlite openssl speex

To configure Asterisk:

CC=gcc-4.8 CXX=g++-4.8 ./configure --with-ssl=/usr/local/opt/openssl --with-sqlite3=/usr/local/opt/sqlite --without-netsnmp --with-unixodbc=/usr/local/opt/unixodbc --without-gtk2

Personally, I also add --prefix=/opt/Asterisk so that Asterisk doesn't get muddled with either system or homebrew managed stuff.

Inline stuff causes warnings with homebrew's GCC, so disable that via menuselect:

menuselect/menuselect --enable DISABLE_INLINE menuselect.makeopts


Hope that helps!
