Subject: [boost] Serialise on Mac OSX 10.8, XCode and GCC

I have an XCode c++ project that uses the static serialisation library (as
well as FileSystem, IOStream and System). The project started out on XCode
3.6 on Mac OSX 10.6, where it successfully built and ran using Boost 1_49_0,
built against Apple's 10.6 SDK.

However, I needed to use the XCode debugger to track down some run-time
issues and found I couldn't access the debugger on this version of XCode
(I'm blind and have to use the VoiceOver utility to gain access to my Mac).
Having taken advice, I upgraded to Mac OSX 10.8, SDK 10.8 and XCode 4.6,
which solves my debugging issue.

Unfortunately, my project no longer links correctly. The linker complains
that it can't find symbols for my architecture (x86_64) - the messages are
in the the form:

rt(char const*)", referenced from:

rride(boost::archive::version_type&, int)", referenced from:

rride(boost::archive::class_id_type&, int)", referenced from:

(I've truncated the output here for brevity). I get no linker errors for
any of the other Boost binaries - it's only the serialisation library that
creates a problem.

The project is configured to compile with the llvmgcc42 compiler, as it also
uses the wxWidgets libraries, which don't support compilation using clang.

Boost versions tried:

1_50_0, 1_52_0 and 1_53_0.

Boost build options tried:

1 - Default (no options specified) - this worked on Mac OSX 10.6, Snow

2 - As follows:

macosx-version=10.3 macosx-version-min=10.6 architecture=combined
threading=multi link=static address-model=32_64

3 - As follows:

architecture=combined address-model=32_64

I'm a novice using Boost and the Mac, so would appreciate any suggestions as
to how I can resolve this issue.
Best wishes.
