C + + calls Python

1, download boost1.52,http://www.boost.org/, unzip the file to D:\boost\boost_1_52_0;

2, download python2.7.3,http://www.python.org/; (boost1.4 support to python2.5)

3, install Python, I installed in the D:\PYTHON25, set the environment variable path D:\PYTHON25;

4. Starting with the program->microsoft Visual Studio 2010->visual Studio tools->visual Studio Command Prompt (2010), open a console

5. In the console, enter the following 3 lines in turn:

CD D:\boost\boost_1_49_0
Bootstrap.bat
Bjam stage–toolset=msvc-9.0–with-python–stagedir= "D:\boost_1_49_0\bin\vc9" Link=static runtime-link=shared Runtime-link=static Threading=multi Debug Release

6, the project properties are configured as follows
Add additional Library directories to the linker, python/libs (in Python's installation directory), Boost/vs2010/lib (in the generated boost directory)

Add-on Add-on library directory for C/C + +, boost (boost download directory), python/include (Python installation directory)

1. Confirm that the project properties are configured as follows
Add additional Library directories to the linker, python/libs (in Python's installation directory), Boost/vs2010/lib (in the generated boost directory)
Add-on Add-on library directory for C/C + +, boost (boost download directory), python/include (Python installation directory)

2, if the use of Boost.python Static library: In the properties-----preprocessor-----preprocessor definition add boost_python_static_lib, otherwise compiled as dynamic, will be prompted to find python_boost*.lib or something

Create a simple.py python file in the current directory with the following contents:

def foo(i = 4):      return i**3
