Hi, I am trying to build boost1_33_1 on solaris 2.9 with CC 5.5 compiler. Libraries like filesystem, serialization, program_options are not built. But other libraries like thread are built perfectly. The libraries which I am not able build I am getting following same error for all libraries /data/tdm/boost_1_33_1/boost/iterator/iterator_facade.hpp", line 838: Error: Could not find a match for boost::iterator_core_access::equal<boost::iterator_core_access::Facade1, boost::iterator_core_access::Facade2>(const boost::filesystem::path::iterator, const boost::filesystem::path::iterator, boost::is_convertible<boost::filesystem::path::iterator, boost::filesystem::path::iterator>). "/opt3/SUNWspro/prod/include/CC/Cstd/./algorithm.cc", line 2370: Where: While instantiating "boost::operator!=<boost::filesystem::path::iterator, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>, boost::bidirectional_traversal_tag, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>&, int, boost::filesystem::path::iterator, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>, boost::bidirectional_traversal_tag, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>&, int>(const boost::iterator_facade<boost::filesystem::path::iterator, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>, boost::bidirectional_traversal_tag, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>&, int>&, const boost::iterator_facade<boost::filesystem::path::iterator, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>, boost::bidirectional_traversal_tag, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>&, int>&)". Please tell me how to solve this problem Thanks
