Check these out and see if it helps.

Also, quadriple check that your base class has at least one virtual function.

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

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... 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, even if it's not in the 1.42 release I'd be very interested by a patch making it works as soon as it's available. In the meantime I'll try to use the version 1.37, on this web page someone reported that this feature was working: https://kyuu.co.uk/article/6 Jean-Charles On Sun, Dec 20, 2009 at 10:25 PM, Robert Ramey wrote:

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.
