Hello, I'm using boost::serialisation, currently with xml_archive. To make a performance test, I tried to switch to another archive format, namely text_archive. However, I cannot read the archive file any longer. Here are the beginnings of both files : ******XML : <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="3"> <GlobalContext class_id="0" tracking_level="0" version="0"> <Pointer class_id="2" class_name="CContainer2[basic]" tracking_level="1" version="0" object_id="_0"> ******Text: 22 serialization::archive 3 0 0 2 18 CContainer2[basic] 1 0 I tried to debug the problem, and could see that the number 2 was incorrectly interpreted as the version of the class GlobalContext, instead of the Id of the following class. It looks like there is a missing 0 in the text file. Does someone have any idea where it may come from ? FYI, I'm using VC++8.0. Best regards, -- Loïc
