compiler tells:

/home/kowalke/Projects/odb/src/main.cpp:1330: error: request for member 'what' is ambiguous
/usr/include/c++/4.2/exception:64: error: candidates are: virtual const char* std::exception::what() const
/opt/boost/include/boost-1_35/boost/exception/exception.hpp:52: error: virtual const char* boost::exception::what() const

code line:

catch ( my_error const& e)
{ std::cout << "my_error: " << e.what() << std::endl; }
