This case is descibed in the rationale section of the documentation. Disregard/disable at your own risk. I don't recommend it. I recommend changing your code to avoid situation which avoids warnings. Robert Ramey Chard wrote:
I've been working on a cut-over of a code-base from Boost 1.34.1 to 1.37 and have found I now get a lot of compiler warnings in the serialization code.
The warnings (emitted via BOOST_STATIC_WARNING) appear to be where non-polymorphic objects are serialized via shared_ptr. The boost serialization code seems to want them to be polymorphic.
Are these benign warnings that can be disabled?
Apologies if this has been raised earlier; I had a good look..
The following example code triggers the warnings (MSVC 7.1):
======
#include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/serialization/serialization.hpp> #include <boost/serialization/shared_ptr.hpp>
using namespace boost;
struct X { template <typename T> void serialize(T &ar, const unsigned int version) {} }; typedef boost::shared_ptr<X> X_P;
void test_ser() { X_P x_p;
std::ifstream ifstr("test.txt"); boost::archive::text_iarchive ar(ifstr); ar & x_p; }
