Hi, The xlC compiler on the IBM issues a severe error when compiling operations.hpp. The compile error appears to be legitimate (use of an undefined class). Unfortunately I don't have a patch to offer, just the bug report. Thanks. -- Noel Belcourt vacpp.compile.c++ ../../../bin.v2/tools/regression/build/vacpp/ release/link-static/process_jam_log.o "../../../boost/filesystem/operations.hpp", line 732.72: 1540-1118 (S) The declaration of "end_itr" uses the undefined class "boost::filesystem::basic_directory_iterator<boost::filesystem::basic_pa th<std::basic_string<char,std::char_traits<char>,std::allocator<char>
