[boost] [Kerim Borchaev <[e-mail]>] [C++-sig] C++ nested classes and addressof.hpp (cannot convert from 'const C::N *' to 'C::N *')

This showed up on the Python C++-sig. I think it's an issue with addressof()


attached mail follows:

Hello c++-sig,

I'm exporting c++ class nested in other c++ class:
/////////////
struct C{
    struct N{};
};

BOOST_PYTHON_MODULE(hello)
{   
    class_<C::N>("C.N");
}
/////////////

and getting this error message:

C:\Tools\boost_1_29_0\boost\utility\addressof.hpp(26) : error C2440: 'return' : cannot convert from 'const C::N *' to 'C::N *'
        Conversion loses qualifiers

What is fun that in addressof.hpp there's a comment:
// Do not make addressof() inline. Breaks MSVC 7. (Peter Dimov)

Strange, isn't it?

Best regards,
 Kerim                          mailto:warkid_at_[hidden]
