Serialization library warnings

[lcarreon@…]

Hi,

I built Boost 1.53.0 on Fedora 18 32/64-bit using the following command:

./b2 link=shared runtime-link=shared address-model=32|64 variant=release

and received the following messages:

libs/serialization/src/basic_iarchive.cpp: In member function ‘const boost::archive::detail::basic_pointer_iserializer* boost::archive::detail::basic_iarchive_impl::load_pointer(boost::archive::detail::basic_iarchive&, void*&, const boost::archive::detail::basic_pointer_iserializer*, const boost::archive::detail::basic_pointer_iserializer* (*)(const boost::serialization::extended_type_info&))’: libs/serialization/src/basic_iarchive.cpp:437:23: warning: variable ‘new_cid’ set but not used [-Wunused-but-set-variable] libs/serialization/src/basic_serializer_map.cpp: In member function ‘bool boost::archive::detail::basic_serializer_map::insert(const boost::archive::detail::basic_serializer*)’: libs/serialization/src/basic_serializer_map.cpp:46:47: warning: variable ‘result’ set but not used [-Wunused-but-set-variable] In file included from ./boost/archive/impl/basic_text_iprimitive.ipp:31:0,

Patch for warnings

[Jeremiah Willcock]

The attached patch, plus the fix for #8525, appears to silence the warnings.

[Johan Lundberg <lundberj@…>]

The issue remains in boost 1.54 beta1

the method looks like this (removing comments):

BOOST_ARCHIVE_DECL(bool) basic_serializer_map::insert(const basic_serializer * bs){

const std::pair<map_type::iterator, bool> result =

m_map.insert(bs);

return true;

}
