Some patches to Boost 1.60.0 RC1 are required to build my software with GCC 4.4.7 and GCC 4.8.2 on CentOS 6 with the following CXXFLAGS: GCC 4.4.7: -Wall -Wextra -Werror -std=gnu++98 -g -O3 -mtune=native -ffast-math -funroll-loops -DNDEBUG -m64 GCC 4.8.2: -Wall -Wextra -Werror -std=gnu++98 -g -O3 -mtune=native -ffast-math -funroll-loops -DNDEBUG -Wno-unused-local-typedefs -Wstrict-null-sentinel -Woverloaded-virtual -m64 The patches we need are: 1. boost/property_tree/detail/json_parser/standard_callbacks.hpp, adding a "return new_tree();" after the "assert(false);" on line 131. This is https://svn.boost.org/trac/boost/ticket/11501 but my co-worker chose to use the return rather than std::abort() 2. boost/property_tree/detail/json_parser_write.hpp which is previously reported as https://svn.boost.org/trac/boost/ticket/5598 3. boost/lexical_cast.hpp, effectively restoring the file to the version released in 1.59.0. See my previous posting: http://lists.boost.org/boost-users/2015/12/85396.php I'm glad to see some of the issues I reported with Beta 1 have been addressed.
