Hi, All I am trying to run Boost.Python in my IDE. Here is my tools: Microsoft Visual Studio 2012 Express Version (64-bit), Python 2.7 (64-bit), Boost 1.54, Windows7 64-bit. And my code is really simple. I created an empty project, and create a source.cpp as follows: #include <boost\python.hpp> #include <Python.h> using namespace std; void main() { return; } After debugging, an error pops out: "error LNK2001: unresolved external symbol __imp___Py_NoneStruct" May I know where am I wrong?
