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!
