Cannot successfully install Boost.Python - c++

Question

I am trying to install Boost.Python on my computer. (Windows7 64bit, Visual Studio 2012, Python 2.7 64bit and Boost 1.54)
Following the instruction, I've successfully installed the Boost Library, and then I have to separately install Boost.Python.
However, as I followed the instruction at here. I am stuck at step 3.1.4.
I input C:\boost_1_54_0\…\quickstart> bjam toolset=msvc --verbose-test test
Then there are 135 unresolved external errors pop out. One of them is:
exec.obj : error LNK2019: unresolved external symbol
__imp__PyEval_GetGlobals referenced in function "class boost::python::api::object __cdecl boost::python::eval(class
boost::python::str,class boost::python::api::object,class
boost::python::api::object)"
(?eval#python#boost##YA?AVobject#api#12#Vstr#12#V3412#1#Z)........\bin.v2\libs\python\build\msvc-11.0\debug\boost_python-vc110-gd-1_54.dll
May I know how can I work around this?
=========================================================
Edit:
Following #Kyle 's advice, I've uninstalled the 64bit Python and replace it with a 32bit Python (2.7.5).
Then I've wrote a very simple code, which is like follows:
#include <boost\python.hpp> // This header used to raise error before
#include <Python.h>
using namespace std;
void main()
{
return;
}
It works well. Then my curiosity pushed me one step further, and I tried the example in my first post. It turns out that those 135 unresolved external errors are gone. Instead, I've got this:

Sorry to bother you with a large chunk of error message, I just want to provide as more information as I can.
About this boost_python-vc110-gd-1_54.dll, I can find it at C:\local\boost_1_54_0_32bit\lib32-msvc-11.0, while the root of my Boost is C:\local\boost_1_54_0_32bit\.
Can anyone help me work around with this?

Answer 1

Like Kyle C mentioned, this is happening because it can't find the lib. If you want to use 64-bit, you need to specify address-model=64 on the command line, plus have the 64-bit version of python correctly specified in your user-config.jam file.
I documented what I had to do to get this running, see the bottom for 64-bit specific config.

Answer 2

This means that the linker can't properly link to the Python lib. I have run into this before when trying to link to 64bit Python. You should try installing 32bit python and see if that works.
