Yeah, I've actually modified demo_xml.cpp to use istringstream and ostringstream. It works. So it is not a problem of stringstream... Thanks, Hughes, James wrote:
No idea. Not tried serialisation with o/istringstream.
Have you tried serialisation to a file, and recovering data from that? Does the XML look correctly formed?

Thanks James, now I can compile this code but when I run it, I got an error. Any idea what's wrong?
g++ -fstrict-aliasing -fomit-frame-pointer -Wall -pedantic -ansi -g -O2 boost_s_map.cpp -o boost_s_map -lboost_serialization
./boost_s_map terminate called after throwing an instance of 'boost::archive::xml_archive_exception' what(): unrecognized XML syntax Aborted

You need to put the archive header files before the rest...

Then

I think this issue of ordering (which continually catches
me out with
its huge list of obscure error messages!) has been fixed in
the latest
version, but Mr Ramey will be able to confirm that.

Hello, I am trying out the boost serialization library.
I've gotten
demo_xml.cpp to work correctly. Now I want to serialize a
customized
class but I got some errors I don't fully understand. Here is teh complete source code and error. Judging from the error it
seems I am
missing something. But I've compared with demo_xml.cpp and
I am lost.
Any help is appreciated.
