Link your C++ module with Python27.lib . Boost.Python is only the wrapper of Python binding so if your module is static, it absolutely needs the Python27.lib . Even we might use dynamic boost.python , but host application might still require Python27.lib if there are any Python APIs called.

I have no idea what the matter is. I will greatly appreciate it if you can help me out.
I don't use Boost.Python myself so I can't give you more specific instructions, but unresolved externals of __imp_* symbols mean that you need to add an import library (the .lib) for a DLL, either by adding a reference to it or by adding it to the linker project settings.
Given the names of the symbols, it's most likely one of the Python runtime DLLs.
