I've attempted rebuilding from scratch, changing only the HOST_CXX var
generated in build/core/combo/HOST_darwin-x86.mk to llvm-gcc
I get this build error:
configure: error: Your host toolchain does not support C++0x/C++11 mode
properly. Please upgrade your toolchain
*** Fix above errors and then restart with "make -f client.mk
build"
make[3]: *** [configure] Error 1
make[2]: *** [/Volumes/firefoxos/B2G/objdir-gecko/Makefile] Error 2
make[1]: *** [build] Error 2
make: *** [out/target/product/inari/obj/DATA/gecko_intermediates/gecko] Error 2
which I haven't seen before. not sure what's causing it.

Christopher,
I've been able to make (what I think) is a good build simply by changing
HOST_CXX inside build/core/combo/HOST_darwin-x86.mk to |llvm-g++|. None of the
other changes appeared to be necessary for me. I wonder if you might confirm
this on your end?
I haven't been able to flash this build, I think because no boot.img is being
created, and updates need to be made. Are you flashing on a production device?
If so, did you run into problems here? If not, then it could be something is
failing because I didn't attempt to make the other changes you mentioned.

Hi is great Christopher - thanks! I've added the following entry to the
documentation:

Let me know if you think this reads ok.

I'll do my best to describe the problem below:
While building B2G with it configured for Inari, I ran into trouble on OSX.
Xcode 5 changes the gcc and g++ compilers in /usr/bin, which breaks the build
process if you try to use them to compile.
In order to work around the problem, I decided to manually change instances of
`g++` and `gcc` to `llvm-g++-4.2` and `llvm-ggc-4.2` in the following folders:
objdir-gecko/_virtualenv/lib/python2.7/config/Makefile
• CC
• CXX
build/core/combo/HOST_darwin-x86.mk
• HOST_OBJCC
• HOST_CC
• HOST_CXX
I also added this to my .userconfig file, for good measure:
export CXX=llvm-g++-4.6
export CC=llvm-gcc-4.6
export CPP=llvm-gcc-4.6
Let me know if I can clarify any of the above a bit further.

Christopher,
That's great news! I'm wondering if you might be so kind as to outline the
files you needed to change?

James,
Yes, the changes I made allowed me to successfully build B2G v1.3. There
were a few other bumps down the road - some other spots needed updates
for CC and CXX vars
In the end, I was able to successfully flash it onto my ZTE Open, and so
far it's working great.
Your assessment of the Xcode 5 update sounds about right to me, gcc and
g++ on my machine were no longer symlinked to my llvm-* binaries as they
may have been in Xcode 4.x
If the output from the build process was correct, then I won't be able
to build for a simulator, but I haven't tried that.

Some updates on what appears to be going on here:
* On Xcode 4.x, /usr/bin/gcc was a symlink, likely to llvm-gcc-4.2 (which
apparently wouldn't produce a usable emulator build - I'm not sure about inari)
* With the Xcode 5 update, the CLI tools have replaced that symlink with an
actual binary, which is clang, as opposed to gcc.
The build obviously doesn't compile with clang, and so things are broken in
their current state. I'd be curious to know if Christopher's modifications
gave him a working inari build.
Where is the appropriate place to report a bug like this?

Actually, Keon is called out specifically:
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Firefox_OS_build_prerequisites#Requirements_for_Mac_OS_X
At this point, I'm willing to say it's not a problem with inari, as I just
attempted to build for emulator and received the same clang errors. There's
definitely a problem with the build process.

Guys, I don't remember where, but I have seen in documentation that the
inari build is not working on Mac OS X. I guess it was in "Build the
Firefox OS" on MDN
Give a look on this tutorial.

And yes, I'm pretty sure the bootstrap script should be passing
--enable-cxx to GCC's configure script. Not entirely sure because it looks
like Clang is being picked up (and causing the errors in the OP). You can
manually fix it by doing:
brew install
