Here are the changes I made. This makes it save but more changes would have to be made in order to load.

Two Problems:
Firstly---> I made the changes you had suggested and it did not work for me. The compilation fails with
"C:\ai\src\external\boost133\boost\archive\basic_xml_oarchive.hpp(86): error C2027: use of undefined type 'boost::STATIC_ASSERTION_FAILURE<x>'". Do I have to define a name-value pair??
If you're using an XML archive, you have to use nvp to assign a name tag to every datum.
(Refer to my previous boost users mailing list posting).
Is it possible for you to attach the cpp code that you compiled and tested (I just want to make sure that I am not doing something stupid).
Secondly----> The output that you had attached just serializes the 'base' object and does not serialize the 'derived' object. I thought the result should have been serialized 'derived' object. Is my understanding wrong?

I just changed
template
inline void save(Archive& ar, derived<T>& obj, const unsigned int version)
{
to
template
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 ------
Linking...
Creating library
c:\BoostMainCVS\libs\serialization\vc7ide\../../../bin/boost/libs/serialization/test/test_zexp_text_archive.test/vc-7_1/debug/threading-multi//test_zexp.lib
and object
c:\BoostMainCVS\libs\serialization\vc7ide\../../../bin/boost/libs/serialization/test/test_zexp_text_archive.test/vc-7_1/debug/threading-multi//test_zexp.exp
run test_zexp with Debug runtime-dynamic text_archive
base: Save
derived<T>::Serialize
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!DOCTYPE boost_serialization>
<originalObject class_id="0" tracking_level="0" version="0">

</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< (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
