I made a couple of changes to your program and compiled it with
both vc 7.1 and borland 5.64 on the current version of the library in the
HEAD.
Here is a summary of the changes.
a) I reordered the headers to conform with a header order requirement
of 1.33 - 1.35 no longer has this requirement.
b) I elminated headers which are not part of the "public" api and
as such are automatically included when necessary.
c) I moved "#include "
to be the first in the list of headers. The default extended_type_info
system is the first one seen. If none is explicitly specified, then the
default extended_type_info_rtti would be used. This will make the
no_rtti ( which should be renamed to something like "by_name") the
default type_info system.
d) I replaced BOOST_CLASS_EXPORT with BOOST_CLASS_EXPORT_GUID
so that I wouldn't have to include <, >, and : characters in the class
export name.
(note this revealed a small error in the newest copy of export.hpp which I
have
fixed on my machine but haven't tested and uploaded yet.
I'm not sure if this helps, but that's what I did.
