Hi,
I tried to expose objects of class:
typedef boost::tuple<ClassA, std::string> RegisterResult;
to python.
I used automatic conversion
(http://www.language-binding.net/pyplusplus/troubleshooting_guide/automatic_conversion/automatic_conversion.html)
but as usual I hit a wall and got unsolvable error.

while running GCC-XML:
/home/macieks/boost/boost_1_42_0/boost/mpl/bool_fwd.hpp:21: sorry,
unimplemented: call_expr cannot be mangled due to a defect in the C++ ABI
I tried to use tuples.hpp from pyogre (it has some few lines added), but
the problem is the same.
I attached simple example files to this mail.
Best regards
