Hi,
I tried including file but still getting the crash.
I have tried to resolve the problem by overloading << as follows :
XMLArchive & operator << (XMLArchive &xa, const struct EMPLOYEE &e)
{
xa << BOOST_SERIALIZATION_NVP(e.id);
xa << BOOST_SERIALIZATION_NVP(e.name);
return xa;
}
and calling it like this :
xa << e;
But, though I am getting the expected result, it still gives me a WARNING As follows :
test.cc: In function ‘int main()’:
test.cc:94: warning: ISO C++ says that these are ambiguous, even though the worst conversion for the first is better than the worst conversion for the second:
test.cc:72: note: candidate 1: XMLArchive& operator<<(XMLArchive&, const EMPLOYEE&)
/usr/include/boost/archive/detail/interface_oarchive.hpp:63: note: candidate 2: Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = EMPLOYEE, Archive = boost::archive::xml_oarchive]
If I call "<<()" as :
operator <<(xa, e);
then it gives me no WARNING.
Also, "ltrace -C " for the crashed program is as below :

So, does anyone know about any solution on,
* either, how to remove the WARNING
* or, how to avoid the crash?
I am using boost-1.37.0-6.fc11.i586 on FC11.

Hi,
I am able to insert the stylesheet tag from inside a constructor
of my new derived class.
Please find below the whole program.
But, I am still getting an error :
terminate called after throwing an instance of 'std::bad_cast'
what(): std::bad_cast
Aborted (core dumped)
on the statement :
xa << BOOST_SERIALIZATION_NVP(e);
in the code below.
The statements :
xa.putTag ("TESTING_XMLCLASS");
xa << BOOST_SERIALIZATION_NVP(tmp);
oa << BOOST_SERIALIZATION_NVP(e);
work as expected.
Can you please let me know what could be the reason for this?
I can't. The only thing that looks missing to me is:
#include
