Sorry about the error message difference - nothing funny is going on. I tested with an 8 character array first and then a 16. I included the error message from the 8 try. I'll try it with an int array and post the results. Jeff Brewer -----Original Message----- From: Ralf W.

I am using Boost 1.30. Sorry I forgot to mention that.
def_readonly seems to still in 1.30 and its implementation is: template <class D, class B> self& def_readonly(char const* name, D B::*pm_) { D T::*pm = pm_; this->add_property(name, make_getter(pm)); return *this; } Is it deprecated though?
Nope. I don't have time to figure out why this isn't working for you right now, but...
If David cannot figure it out, maybe it is time to admit that I am lost, too. I am doing all the time what you are trying to do, under many platforms including Visual C++ 7.1. However, I've never tried it with char arrays. What happens if you change your small test to work with, say, int instead of char? I am not sure it will help, but here is my "to_tuple" converter: template <typename ContainerType> struct to_tuple { static PyObject* convert(ContainerType const& a) { boost::python::list result; for(std::size_t i=0;i<a.size();i++) { result.append(boost::python::object(a[i])); } return boost::python::incref(boost::python::tuple(result).ptr()); } }; Your's looks good, too, but maybe there is a subtlety that VC chokes on? I also noticed that your test involves char array[16], but you quote an error message related to char array[8]? Where does that factor of two come from? OK, enough shots in the blue for now. Hope this is useful somehow. Ralf __________________________________ Do you Yahoo!? Yahoo!
