Boost.python Compiling and demonstrating sample

Linux build boost Link: http://blog.csdn.net/majianfei1023/article/details/46761029

Compile and install the boost yesterday, ready to use Boost.python to write a python call C + + code sample, the result stepped on a lot of pits.

First put the code:

1.student.cpp, an ordinary C + + class

#include <iostream> #include <string>using namespace Std;class student{public:void setname (String str) { name_ = str;} String GetName () {return name_;} void setage (int age) {Age_ = age;} int Getage () {return age_;} Private:string name_;int Age_;};

2.student2py.cpp, the code that encapsulates C + + as a Python module, uses the Boost.python

#include <boost/python.hpp> #include "student.cpp" using namespace boost::p Ython; Boost_python_module (example)  //python module {class_<student> ("Student"). DEF ("SetName", &student:: SetName). def ("GetName", &student::getname). def ("Setage", &student::setage). def ("Getage", &student:: getage). Add_property ("name", &student::getname,&student::setname). Add_property ("Age", &student:: Getage,&student::setage);}

3.makefile

4.example.py,python Calling *.so Demo sample code

Import Examplestu = Example.student () stu.setname ("MJF") stu.setage (+) print Stu.nameprint stu.age

thought it would be smooth sailing. The result is a variety of tangled questions:

1.

.. /boost/python/detail/wrap_python.hpp:50:23:error:pyconfig.h:no such file or directory
./boost/python/detail/wrap_python.hpp:75:24:error:patchlevel.h:no such file or directory

./boost/python/detail/wrapper_base.hpp:21:error:expected initializer before ' * ' token
./boost/python/detail/wrapper_base.hpp:23:error:expected initializer before ' * ' token

A variety of search data found to be the problem of Python.

Missing dependent library Python-devel, to install:

sudo yum install Python-devel

2. Overcome the above problem. New problems have also been discovered.

/usr/bin/ld:cannot Find-lboost_python

A check, sure enough to find no libboost_python.so, installed boost when I was indeed completely installed. Do not know how to do, did not pretend to anticipate.

Once again, Boost.python.

. /bootstrap.sh--prefix=/home/mjf/lib

sudo./b2--with-python Install

Accomplished, took nearly two hours to solve some problems. Ability to successfully invoke example.so with Python

Finally: Thanks to StackOverflow, the answers to many questions can be found on top.
