Hi all, trying to compile one of the simplest examples in the doc (see code below) for the python-binding of boost::parameters using Visual Studio 2005 prof, I get the following error: error C2440: 'initializing' : cannot convert from 'const boost::parameter::aux::use_default_tag' to 'unsigned int' ...\boost_1_35_0\boost\parameter\aux_\maybe.hpp on line 59 boost::python works well in binding non-boost::parameter-functions. Also, "boost_1_35_0\libs\parameter\test\python_test.cpp" compiles without errors. When all parameters of window::open(..) are set as being 'required' instead of 'optional', the code below finally compiles, too. Somebody, please give me a hint, I don't know where to start. Thanks in advance! /* from: http://www.boost.org/doc/libs/1_35_0/libs/parameter/doc/html/python.html */ #include #include #include #include BOOST_PARAMETER_KEYWORD(tag, title) BOOST_PARAMETER_KEYWORD(tag, width) BOOST_PARAMETER_KEYWORD(tag, height) class window { public: BOOST_PARAMETER_MEMBER_FUNCTION( (void), open, tag, (required (title, (std::string))) (optional (width, (unsigned), 400) (height, (unsigned), 400)) ) { } }; struct open_fwd { template void operator()( boost::type<void>, window& self , A0 const& a0, A1 const& a1, A2 const& a2 ) { self.open(a0, a1, a2); } }; BOOST_PYTHON_MODULE(my_module) { using namespace boost::python; namespace py = boost::parameter::python; namespace mpl = boost::mpl; class_<window>("window") .def( "open", py::function< open_fwd , mpl::vector< void , tag::title(std::string) , tag::width*(unsigned) , tag::height*(unsigned) > >() ); } -- GMX startet ShortView.de.
