Re: [Boost-users] Boost Serialization with a dynamically loaded sharedlibrary

I got it to compile, see my second reply to your last message. Robert Ramey wrote:

Hmm - I just compiled it on a couple of cmpilers here. gcc 34, MSVC 7.1, borland 5.64.

I'm using boost 1.34 + improvements in the serializaiton lirbrar so it might not be the same as you.

What version of boost are you using? What version of gcc?

If its 1.33 or below try using the following header setup:

...

#include #include

...

#include #include

I compiled this code with the change below. Uncomment 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
