OK - found it now.
I've invested a little time to look into it.
A couple of things
a) turns out I never really built/ran this this
test. It depended on my getting
more understanding to how to test a dll with boost
and setting my msvc IDE
to handle this. Lately I got this squared
away but I hadn't run the test.
a) the test uses the polymorphic_archive.
This seemed to confuse me (mostly
because the word "polymorphic" is all over the
place) so I changed it to text_?archive.
b) So I ran the test and found a couple of dumb
bugs. Need to link to the
dll_polymorphic_derived2.dll, etc.
c) needed to add a marcro
BOOST_SERIALIZATION_FACTORY_0(polymorphic_derived2)
to the header so the plugin factory would
work.
d) After all this - the program builds and runs -
but has fails to recover the proper
pointer. I"m looking into this. I'll
uploaded updated test to trunk when it's done.
I do not think this fix will make it into it
into boost 1.42.

I'm
working with the latest version 1.41
You can have a look here, I'm not
sure to understand the boost repository, but it looks quite similar of what I
have:
https://svn.boost.org/trac/boost/browser/branches/release/libs/serialization/test
You'll
find the source file I'm talking about (it's actually test_dll_plugin.cpp and
not test_plugin_dll.cpp but you'd have made the correction yourself) along
with the bjam file with the commented line.

Ok,
I understand that it should work somehow, so I'm
doing something wrong. I've checked it and I got quite a few virtual
abstract functions in my main class overridden in the derived
classes.
I've seen all these demo and test. And the one that comes
closer to my problem is definetly test_plugin_dll.cpp Unfortunaltly it is
commented in the Jam file and when I uncommented the line, it won't
compile.
How can I compile it ?
Thanks for your
help,

note that there a few demos of this

helpful.
Also there is test_exported_dll and
test_simple_dll.
Check these out and see if it
helps.
Also, quadriple check that your base class
has at least one virtual function.

Hi,
I've been using the boost serialization on many
projects. But I can't manage to make it work on my current project.
Basically, I've a main application and an abstract class
located in a separate dll. The application loads dynamically plugins
which defines classes derived from the abstract class. Then I'm trying
to serialize a class created by a plugin using a pointer to the
abstract class, I always get a "Unregistered class" exception. I've
used the BOOST_CLASS_EXPORT macro in the plugins trying to make the
boost serialization library aware of my classes without any success so
far.
Looking in the source directory and specially in the
"test" directory, I've seen that what I'm trying to do is the same as
the test described by the file test_dll_plugin.cpp, unfortunately, it
seems the test is not compiled and I can't manage to make it link
without error.
So my main concern is: is this feature supposed to
be working ? If not I'll have to review my design. If it does what is
the magic to make it work (like how to compile test_dll_plugin.cpp or
another simple working example) ?
Thanks for any
help,
Jean-Charles
