http://stackoverflow.com/questions/4331599/calling-python-functions-from-c This
a simple problem.But they are not the same.My problem is:
boost::python::object func;
Rectangle ret;
func(&ret); // How to make a parameter of c++ instance's pointer to a

That error has nothing to do with boost python. Apparently you did not
link against the definition for the class Rectangle. You need to link
against the object file generated from the definiton of Rectangle,
usually you would have a Rectangle.cpp and generate a Rectangle.o.
Your python module needs
I have write more code.what documentation? http://www.boost.org/? Looks
some confused.I have not found the description of this problem.
BOOST_PYTHON_MODULE(ctopython)
{
using namespace boost::python;
class_ ("Rectangle")
.def("area",&Rectangle::area)
;
def("runtest",runtes
yes..I try it..
