"decl" for what? I should have written that I am using a .def file to get getobj out of the dll, to add some more missing information, I am running MSVC 2005 on Win XP. The sample is a compileable and runnable solution Where can I find a introduction to running the tests? I have spent 2 hours trying to get the test cases to run. Christian Robert Ramey skrev:
Shouldn't there be some "decl" statements in here?
There is a test in the package test_dll_exported...
Perhaps you might check to see that that test works with your setup.
I'm now in the process of adding tests for this functionality for version 1.40 . Can't promise I'll make the deadline though.

I am working on a programwith pluggable classes delivered in DLLs, so I have an virtual abstract base class in my EXE and both abstract and concrete classes in a hiearchy in my first DLL. I am trying ot serialize the derived class instances through a base class pointer. I am not able to get it to work after reading the samples in the documentation and the most likely looking threads here.
So I broke it down in to a sample EXE/DLL and can still not get it to work. I am using version 1_38 currently, also tried with 1_36_0
I am getting the exeption on oserializer.hpp:374 where the comment says // note:if this exception is thrown, be sure that derived pointer // is either registered or exported.
In my opinion I am exporting my derived class, but I am feeling that it is probably going into the wrong instance, since the export code is going into the DLL, but I can not find any other recomendation.
So what am I missing ...
