Re: [Boost-users] Problems non intrusively serializing templateinheritance classes, boost 1.33

I just changed

template<class Archive, class T>
inline void save(Archive& ar, derived<T>& obj, const unsigned int version)
{

to
template<class Archive, class T>
inline void save(Archive& ar,  const nderived<T>& obj, const unsigned int 
version)
{

at line # 91,

and I removed the l // from line #85

compiled and ran with VC 7.1 Seemed to work find. the output was:

------ Build started: Project: test_zexp, Configuration: Debug 
runtime-dynamic text_archive Win32 ------

</originalObject>

which looks correct to me.

I had tried putting 'const' in the save function header. The code 
compilation fails with "boost::STATIC_ASSERTION_FAILURE<x>" at the 
"save_override" function in "basic_xml_oarchive.hpp".

I tried "BOOST_SERIALIZATION_BASE_OBJECT_NVP(obj)" and 
"boost::serialization::base_object< <base<T> >(obj)" and I am not able to 
compile the source code. Base object serialization macros are not able to 
deduce the template argument list.

Hi,
  I am relatively a new to Boost serialization classes. I am trying to 
serialize a derived template class.

template<class T> class base {};
tempate<class T> class derived : public base<T> {};

I am trying to serialize 'derived'  and have tried many different things. I 
am unable to serialize the inherited template classes.
For some reason the code calls
(1) 'derived::Serialize'
(2) 'base::Save'
and never executes 'derived:: Save' and doesnot serialize the 'derived' 
object properly.

I am attaching the source code (SerializeTemplates.cpp) and the 
output(output.txt) of the program.
I am using MSVC7.1, debug mode, Boost 1.33, Spirit 1.8
It will be great, if somebody could point out what I am doing wrong.
Thanks,
Pyush
