I compiled the boost 1.50.0 libraries using b2 with the correct Python configuration. Here's the relevant ouput from the command b2 --debug-configuration:

The Boost C++ Libraries were successfully built!
I have set the linker directories correctly and linked to the appropriate output files (libboost_
python3-vc100-mt-1_50.lib on release, and libboost_python3-vc100-mt-gd-1_50.lib on debug). I am using a self compiled python distribution, but I've tried with the standard ones too and the result isn't any different.
The link errors I'm getting when I compile are:
error LNK2019: unresolved external symbol "__declspec(dllimport) protected: __thiscall boost::python::detail::str_base::str_base(char const *)" (__imp_??0str_base@detail@python@boost@@IAE@PBD@Z) referenced in function "public: __thiscall boost::python::str::str(char const *)" (??0str@python@boost@@QAE@PBD@Z)
error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall boost::python::detail::str_base::~str_base(void)" (__imp_??1str_base@detail@python@boost@@QAE@XZ) referenced in function "public: __thiscall boost::python::str::~str(void)" (??1str@python@boost@@QAE@XZ)

fatal error LNK1120: 3 unresolved externals
The test code which produced those errors boils down to:
using namespace boost::python;
object main_module = import("__main__");
I have used Boost.Filesystem with the same build configuration and it didn't cause me any problems.
I hope somebody can help me with this issue, it's really confusing me!
Update: I just read some vague text about the define BOOST_PYTHON_STATIC_LIB; i'm not sure if i'm headed in the right direction with this (since afaik it wasn't mentioned in the build process), but either way, it gives me an even more confusing error:
LINK : fatal error LNK1104: cannot open file 'python27.lib'
I don't know why it trys to link with that lib when the python-cfg output clearly shows it found my python33 dist (which my application is already linking with; python33.lib).
