Oggetto: Building "hello world" with Boost.Python
i want to use a C++ dll (containing overloaded functions) with Python.
I'm trying to use Boost.Python.
I dowloaded it and now I'm doing the hello world tutorial situated in the boost installation folder in \libs\python\example\tutorial
I got also bjam and configured it to work with gcc and python 2.5.
This is the hello.cpp file to export:
char const* greet()
return "hello, world";
using namespace boost::python;
I use this Jamroot file (that is in the same folder as hello.cpp):
# Copyright David Abrahams 2006. Distributed under the Boost
# Software License, Version 1.0. (See accompanying
# file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt)
# Specify the path to the Boost project. If you move this project
# adjust this path to refer to the Boost root directory.
: ../../../.. ;
# Set up the project-wide requirements that everything uses the
# boost_python library from the project whose global ID is
: requirements <library>/boost/python//boost_python ;
# Declare the three extension modules. You can specify multiple
# source files after the colon separated by spaces.
python-extension hello_ext : hello.cpp ;
# A little "rule" (function) to clean up the syntax of declaring tests
# of these extension modules.
local rule run-test ( test-name : sources + )
import testing ;
testing.make-test run-pyd : $(sources) : : $(test-name) ;
# Declare test targets
run-test hello : hello_ext hello.py ;
In the Jamroot file i changed only this:
: ../../../.. ;with this(the boost root folder on on my disk):
: C:/boost/boost_1_35_0 ;When i run bjam it seams that it builds well, only with some warning, but without any error.
In the tutorial they say that if all is well i should now have built the DLLs.
But the only things in there are 2 files: hello.o and hello.lib
I can't use these as python modules, how can i get the DLL? and the .pyd?
Thanks in advance.
