Boost 1.55 Python with Windows Visual Studio 2013, Link Error

Question

I download boost1.55 zip from official website and then build with command bootstrap and b2. And I tried example code, but it has a link error.

1>LINK : fatal error LNK1104: cannot open file 'libboost_python-vc120-mt-gd-1_55.lib'

Below is what I did.

1. New project win32 Console application, DLL empty.

2. Add include path, library path in VC++ DIRECTORIES like the below.

   INCLUDE DIRECTORIES: C:\boost\boost_1_55_0;C:\Python27\include 
   LIBRARY DIRECTORIES: C:\boost\boost_1_55_0\libs;C:\Python27\libs
   

.

#define BOOST_PYTHON_STATIC_LIB
#include <boost/python.hpp>
using namespace boost::python;

struct World
{
    void set(std::string msg) { this->msg = msg; }
    std::string greet() { return msg; }
    std::string msg;
};


BOOST_PYTHON_MODULE(hello)
{
    class_<World>("World")
        .def("greet", &World::greet)
        .def("set", &World::set);
}

Edit

If i add the library directory, C:\boost_1_55_0\stage\liblike an answer below, it make many errors happen, around 200 below is just the part of errors.

Answer 1

The "LIBRARY DIRECTORY" should reference C:\boost_1_55_0\stage\lib instead of C:\boost\boost_1_55_0\libs.
