one of the serialization functions.
Hmm. I still couldn't compile it with those changes. Here's the cpp file I
tried to compile:
error.cpp:
#include
#include
#include
//BASE
class base
{
public:
virtual void virt_func() = 0;
};
BOOST_IS_ABSTRACT(base);
//DERIVED
class derived : public base
{
public:
void virt_func() {}
template<class Archive>
void serialize(Archive& ar, const unsigned int version);
};
#include
BOOST_CLASS_EXPORT_GUID(derived,"derived")
//MAIN
int main()
{
return 0;
}
And when I try to compile it:
$ g++ error.cpp -lboost_serialization
