Boost C++ Libraries: Ticket #8720: Fix for boost serialisation, portable binary archive on AIX

Boost C++ Libraries: Ticket #8720: Fix for boost serialisation, portable binary archive on AIX https://svn.boost.org/trac10/ticket/8720 On most platforms, char is signed, however on AIX by default char is unsigned. The portable binary archive assumes the char type is signed. The fix is simply to replace 'char' with 'signed char' in the correct places. This is a fairly safe and quick fix, can I please ask the authors of this library to add this fix, for the next version of boost. Here are the changes I made: (flagged under ' changed ' comment -------------------------------------------------------- portable_binary_iarchive.hpp <blockquote> void load(signed char & t){ changed <blockquote> this->primitive_base_t::load(t); </blockquote> } </blockquote> ------------------------------------------------------------- portable_binary_iarchive.cpp void portable_binary_iarchive::load_impl(boost::intmax_t & l, char maxsize){ <blockquote> signed char size; changed l = 0; this->primitive_base_t::load(size); </blockquote> <blockquote> if(0 == size){ <blockquote> return; </blockquote> } </blockquote> <blockquote> bool negative = (size < 0); ...... </blockquote> ----------------------------------------------------------------- portable_binary_oarchive.hpp <blockquote> void save(const signed char & t){ changed <blockquote> this->primitive_base_t::save(t); </blockquote> } </blockquote> ----------------------------------------------------------- portable_binary_oarchive.cpp void portable_binary_oarchive::save_impl( <blockquote> const boost::intmax_t l, const char maxsize </blockquote> ){ <blockquote> signed char size = 0; changed </blockquote> <blockquote> if(l == 0){ <blockquote> this->primitive_base_t::save(size); return; </blockquote> } </blockquote> <blockquote> .......... </blockquote> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/8720 Trac 1.4.3
