[Boost-users] How to expose self defined type in boost.python

14 Jan 2008

      Hi,

I try to use boost.python to invoke C++ library in Python, so I need to
expose types and classes.
Here is the c++ head file:

 *typedef int XTYPE;*
*class XCLASS*
*{*
*public:*
*        XTYPE getvalue( void ){ return XTYPE( 3 ); }*
*};*

So I write exposing code in BOOST_PYTHON_MODULE like this:

 *BOOST_PYTHON_MODULE( x )*
*{*
*        class_< XCLASS >( "XCLASS" )*
*                .def( "getvalue", &XCLASS::getvalue, return_value_policy<
copy_non_const_reference >() )*
*        ;*
*}*

but there is compiling error as using of undefined type.
what shall I do to make the type XTYPE known by boost.python?
Thanks in advance!
