hmm. this is all correct in my code. In fact, this trivial piece of code
does not compile:

#include <boost/serialization/base_object.hpp> 
#include <boost/archive/text_oarchive.hpp>       
#include <boost/archive/text_iarchive.hpp> 
#include <boost/serialization/export.hpp>           //AFTER all archive
headers

//BASE 
class base 
{ 
public: 
  virtual void virt_func() = 0; 
}; 
BOOST_IS_ABSTRACT(base); 

//DERIVED 
class derived : public base 
{ 
public: 
  void virt_func() {} 
}; 
BOOST_CLASS_EXPORT_GUID(derived,"derived")  //no namespaces here

//MAIN 
int main(){return 0;}

Is this code correct? Does it compile for you?

What do you mean by "Check test export"?

Thanks for all the time you're putting into helping me,
