[Boost-users] Problem linking to serialisation library on Mac OSX

Hi,

I built my boost on Mac OSX 10.8 as follows:

./bootstrap.sh -prefix=/users/tim/developer/libraries/boost_1_50_0/stage
./b2 -address-model=32_64 stdlib=libc++

This ran boost.build with the Darwin toolset, as expected, and generated no
errors.  Checking the stage/lib folder revealed a complete set of static and
dynamic library files with appropriate date-time stamps.  I specified the
linker as libc++ as the project I'm working on using XCode 4.6 uses
wxWidgets 2.9.4, which requires that the project be compiled using Apple's
GCC instead of the default compiler (this, in turn, means that libc++
becomes the linker used by the project). 

However, when I try to build my XCode project, I get errors of the form:

Undefined symbols for architecture x86_64:
 
"boost::archive::basic_xml_iarchive<boost::archive::xml_wiarchive>::load_sta
rt(char 

All of the errors refer to boost::archive or boost::serialisation.  My
project also uses the boost FileSystem, IOStream  and System libraries,
which don't generate any errors.  I've found an awful lot of references to
this issue on the web (particularly StackOverflow), but have yet to find an
answer/solution.  I'm pretty sure that I'm using the correct command-line
options (I didn't specify architecture=combined, as Mac OSX SDK 10.8 no
longer supports PPC), but I'm confused by the plethora of available build
options, as I'm a novice on this platform.  

The project is a cross-platform effort and the same source code presented to
my Windows VS2010 32/64-bit project builds and runs.  Similarly, the same
project built and ran under Mac OSX 10.6 with XCode 3.6 - I'd gladly revert
to the older Mac O/S and XCode except for the fact that I'm a blind
developer and the debugger provided in XCode 3.6 is not accessible to me
using Apple's VoiceOver speech output utility (the debugger in XCode 4.6
holds out more hope for being usable).
  
I'd greatly appreciate any tips and tricks for resolving this problem, so
many thanks in advance.

Best wishes.
