Re: [Boost-users] [serialization] Export macro doesnt work

Ok I tried one test code and it worked, but when I moved the all the classes in header file and but the export macro in cpp file it fails with "derived class not registered or exported". Then I moved the export macros to main.cpp right before main() and before the saving/loading calls, and that did the trick. So it seems export's need to be in same CPP file where the loading/saving starts? Or is it in same cpp where the function is?

I have rather simple project considering its not DLL or Lib where I need those exports. And I honestly dont know what the manual is saying about BOOST_CLASS_EXPORT as I have applied it to my project according to my best ability, and it doesnt work.

So can you help and give instruction how to use the macro?

I have included BOOST_CLASS_EXPORT(SomeClass) after every #include "SomeClass.h" but something is wrong.

I dont know what to try.

I followed the manual to my best ability.

Try building one of he demos or tests that come with the library.

Make sure that your base classes have at least one virtual function.

thanks.

Hi I was trying to use BOOST_CLASS_EXPORT for all my classes in order to save them but I always got unregistered class error. So I used oa.register_type<object>(); for the class that was causing the error and problem solved. But why doesnt the BOOST_CLASS_EXPORT macro work?

because you're not using it properly.

Why I need to use oa.register_type<object>(); ?

because you can't get EXPORT to work.
