Building Thunderbird on OS X Lion (10.7) and XCode 4.2

Blake Winton

A few people recently asked me about building Thunderbird on the latest version of Mac OS X. Since I have it working, and to give myself a place to point to the next time they ask, I figured it would be a good idea to blog about it.

So, here’s my .mozconfig.

# For NSS symbols
export MOZ_DEBUG_SYMBOLS=1
#ac_add_options --enable-debug-symbols="-gdwarf-2"

#Use ccache
#ac_add_options --with-ccache=/usr/local/bin/ccache

# We don't have GCC anymore, since XCode 4.2, so use clang instead.
CC=clang
CXX=clang++

There are probably a bunch of things I don’t really need in there, so if anyone wants to take it, and cut it down to the minimal set, I would definitely appreciate it. But in the meantime, this works for me, and will probably work for you, too.
