Hi, When compiling Boost.Python using the *.dsw visual studio project file in the boost/libs/python/build directory, the project fails to link. Note that I've converted this project to a Visual Studio 9 project. Below are the linker errors: 1>Linking... 1> Creating library .\../bin-stage/boost_python_debug.lib and object .\../bin-stage/boost_python_debug.exp 1>function.obj : error LNK2001: unresolved external symbol "char * boost::python::objects::detail::cpp_signature_tag" (?cpp_signature_tag@ detail@objects@python@boost@@3PADA) 1>function.obj : error LNK2001: unresolved external symbol "char * boost::python::objects::detail::py_signature_tag" (?py_signature_tag@ detail@objects@python@boost@@3PADA) 1>function.obj : error LNK2019: unresolved external symbol "public: static class boost::python::list __cdecl boost::python::objects::function_doc_signature_generator::function_doc_signatures(struct boost::python::objects::function const *)" (?function_doc_signatures@ function_doc_signature_generator@objects@python@boost@@SA?AVlist@34@ PBUfunction@234@@Z) referenced in function _function_get_doc 1>../bin-stage/boost_python_debug.dll : fatal error LNK1120: 3 unresolved externals 1>Build Time 0:00 1>boost_python - 4 error(s), 0 warning(s)
